The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. Code Revisions 1 Stars 14 Forks 3. This paper will introduce its usage in detail. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. The url parameter should be a valid URL. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. This filter works only with HTTP (including HTTPS) requests. The following example below is invalid: The Redis implementation is based on work done at Stripe. https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). Easy to extend and/or customize using standard Spring patterns It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. This is the number of tokens the token bucket can hold. URI variables may be used in the value and will be expanded at runtime. Modifying the Way Remote Addresses Are Resolved, 5.12. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in The default filter is a rewrite path filter with the regex /serviceId/?(?. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. Passing headers with Spring Cloud Feign. SetRequestHeader is aware of URI variables used to match a path or host. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. .route("test1", r -> { It is the permissible size limit of the request defined in bytes. 4.1. The DedupeResponseHeader filter also accepts an optional strategy parameter. The lowercase full name of the secure header needs to be used to disable it.. and puts it in a request header for the downstream requests. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. Value 3.9. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. This uses Java regular expressions for a flexible way to rewrite the request path. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. httpStatusCode: The HTTP Status of the request returned to the client. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. This predicates matches the Host header that matches the pattern. Spring cloud gateway response body modification. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. For example, you can match on the path segment of the URL or the HTTP method of the request. 25Modify Response Body GatewayFilter Factory; The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). Have a question about this project? response Header Transformations: . To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. These are basic guides to writing some custom components of the gateway. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. Predicate: This is a Java 8 Function Predicate. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. This property takes a list of filters. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. If youre using load-balanced routes, you need to explicitly define your. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. The default is http|https|ftp|ftps. It is the name of the header to be removed. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. You can enable, disable, or configure policies to control how they modify APIcast. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. Multiple matching segments are allowed. Download ZIP. Once a request has been marked as routed, other routing filters will not route the request again, It must be a Java System Property, not a Spring Boot property. Configure for High Availability. connect-timeout must be specified in milliseconds. Server. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. It uses the Netty HttpClient to make the downstream proxy request. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). If You Appreciate This, You Can Consider: We are thankful for your never ending support. Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). You must use $\ to mean $ because of the YAML specification. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. You can read more about them in the. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. Setting this value to zero blocks all requests. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. pass the authentication token downstream to the services (in this case With MVC, it also supports forwarding to a local handler through the forward() method. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. 3,AddResponseHeader GatewayFilter Factory. The SetRequestHeader GatewayFilter factory takes name and value parameters. There is an abstract class called AbstractRoutePredicateFactory which you can extend. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts results in dropped requests (HTTP 429 - Too Many Requests). The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. It offers a simple way to manipulate the request path by allowing templated segments of the path. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. The To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query So a request to /hello is sent to /mypath/hello. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. return r.host("*.somehost.org").and().path("/somepath") It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). In future milestone releases, there will be some KeyResolver implementations. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. responseCode; responseHeaderTransformations; responseMessage; type; . The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. The first one is the For a full working sample see this project. The KeyResolver is a simple one that gets the user request parameter AddRequestHeader is aware of the URI variables used to match a path or host. This predicate matches with a header that has the given name whose value matches the regular expression. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled value or the String representation of the HttpStatus enumeration. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). Here, you can modify requests and responses before or after sending the downstream request. To configure Global http timeouts: The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. This predicate matches requests that happen before the specified datetime. Closing due to lack of requested feedback. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. Writing Custom GatewayFilter Factories, 17.2.1. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. API gateway provides a unified access for services in microservices architecture. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. The RemoveResponseHeader GatewayFilter factory takes a name parameter. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. application.yml. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. For example, given a Gateway that has 1 replica, the following will . This predicate matches requests that happen after the specified datetime. For relative redirects, you should use uri: no://op as the uri of your route definition. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted In subsequent calls, this value is recalculated with the number of seconds left until the response expires. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/1/ or /red/blue or /blue/green. Those values are then available for use by GatewayFilter factories. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. Since the request can be read only once, we need to cache the request body. response-timeout must be specified in milliseconds. application.yml. URI variables may be used in the value and will be expanded at runtime. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. Displays the list of GatewayFilter factories applied to a particular route. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The request returns a 200 without a response body. Spring Cloud Gateway includes many built-in route predicate factories. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. status codes you want to trip the circuit breaker you can either use an integer with the status code keyResolver is a bean that implements the KeyResolver interface. Cleanliness 4.4. consumer can be a pure Client (like an SSO application) or a Resource By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. Each item defines the name and the arguments of a given predicate. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. The pattern is an Ant-style pattern with . The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. By default, it creates a NettyChannel by using the default TrustManagerFactory. There are convenience methods that you can use to mark an exchange as routed The route configuration allows applying CORS directly to a route as metadata with key cors. It uses the Netty HttpClient to make the downstream proxy request. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. Retrieving the Routes Defined in the Gateway, 15.5. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. However, there is one in another application, registered under localhost:9994. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. A number of timeouts are associated with this handshake. Route: The basic building block of the gateway. APIcast standard policies Configuring Predicates and Filters For, 15.4. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. ServerHttpResponse interface. .filters(f -> f.addRequestHeader("header1", "header-value-1")) AS_IN_REQUEST: The version is stripped only if the original request path contains no version. To clear the routes cache, make a POST request to /actuator/gateway/refresh. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. Sign in also note that the gist doesn't take the decoders into account from upstream like here. See the documentation for @RequestMapping in Spring MVC for more details of those features. In some cases you might want to trip a circuit breaker based on the status code If you would like us to look at this issue, please provide the requested information and we will re-open the issue. Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. The circuit breaker config object takes a list of So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. This is the value of the Location header. This filter also automatically calculates the. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. If the information is not provided within the next 7 days this issue will be closed. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. status: The HTTP status of the request returned to the client. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. The RequestRateLimiter is not configurable with the "shortcut" notation. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. The RemoveRequestParameter GatewayFilter factory takes a name parameter. name can contain a space-separated list of header names. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. The collection of filters applied to the route. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. Both offer the same possibilities. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Any otherway is there apart from blocking call? This predicate matches cookies that have the given name and whose values match the regular expression. regexp, so green and greet would match. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters.
