. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. A burst of 20 is allowed, but, in the next second, only 10 requests are available. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. 3,AddResponseHeader GatewayFilter Factory. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. Sign in The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". Let's simplify this scenario. This interface and its usage are subject to change in future milestone releases. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. 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 example below is invalid: The Redis implementation is based on work done at Stripe. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. Looking for a place to stay in Gunzenhausen? When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. Since the request can be read only once, we need to cache the request body. Easy to extend and/or customize using standard Spring patterns The following listing shows how it works: This style also allows for more custom predicate assertions. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. value or the String representation of the HttpStatus enumeration. The first one is the By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. It uses the Netty HttpClient to make the downstream proxy request. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. to the exchange attributes. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. It must be a valid Spring HttpStatus. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. That is not a complete working sample, it is just some code. It offers a simple way to manipulate the request path by allowing templated segments of the path. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. connect-timeout must be specified in milliseconds. 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. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. 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. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Spring Cloud Gateway includes many built-in GatewayFilter Factories. However, there is one in another application, registered under localhost:9994. backoff: The configured exponential backoff for the retries. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. Well occasionally send you account related emails. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. I think i have to go for a blocking call here. 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. If it is not provided, the value of the Host request header is used. Then the proxy request is made. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. 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. The RemoteAddr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). The Between route predicate factory takes two parameters, datetime1 and datetime2 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). This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. 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. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. and puts it in a request header for the downstream requests. If it is not matched, the filter does nothing. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. There are convenience methods that you can use to mark an exchange as routed Created 6 years ago. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) application.yml. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. essentially skipping the filter. Creating and Deleting a Particular Route, 15.8. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Sharing Routes between multiple Gateway instances, 17.1. You can use it inside a regular Spring web handler as a method parameter. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. A number of timeouts are associated with this handshake. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). The KeyResolver is a simple one that gets the user request parameter It uses the Spring WebSocket infrastructure to forward the websocket request downstream. The filter takes a maxSize parameter. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. It uses the Netty HttpClient to make the downstream proxy request. Tripping The Circuit Breaker On Status Codes, 12.4.1. The status parameter should be a 300 series redirect HTTP code, such as 301. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. The preceding route matches if the request contained a red query parameter whose value matched the gree. All of these predicates match on different attributes of the HTTP request. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. There are many caching cases on the network, but there are various Bug problems in the testing process. . Modify request body. The args key is a map of key value pairs to configure the predicate or filter. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. It uses Java regular expressions for a flexible way to rewrite the response header value. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. SetRequestHeader is aware of URI variables used to match a path or host. You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. This applies the filter to all requests. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. 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. The AddRequestHeader GatewayFilter factory takes a name and value parameter. The RemoveRequestHeader GatewayFilter factory takes a name parameter. For example, to reference a filter named Something in configuration files, the filter }, 4. .uri("http://someuri") The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. response-timeout must be specified as a java.time.Duration. It is the permissible size limit of the request defined in bytes. Currently, only forward: schemed URIs are supported. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. 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). To clear the routes cache, make a POST request to /actuator/gateway/refresh. The ServerHttpResponse instance is used to . Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. .route("test1", r -> { This uses the URI templates from Spring Framework. If you would like us to look at this issue, please provide the requested information. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. 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. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). 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. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 The RemoteAddr Route Predicate Factory, 5.10.1. Code Revisions 1 Stars 14 Forks 3. it is proxying. response-timeout must be specified in milliseconds. The circuit breaker config object takes a list of Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The By default, it creates a NettyChannel by using the default TrustManagerFactory. Route: The basic building block of the gateway. 25Modify Response Body GatewayFilter Factory; which are java ZonedDateTime objects. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). AddResponseHeader is aware of URI variables used to match a path or host. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. The lowercase full name of the secure header needs to be used to disable it.. Displays the list of routes defined in the gateway. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. The default request size is set to five MB if not provided as a filter argument in the route definition. 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. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. This is the number of tokens the token bucket can hold. 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. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; Displays the list of GatewayFilter factories applied to a particular route. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ aws api gateway parameter mapping. For more detailed examples of how to use any of the following filters, take a look at the. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. By default, if the KeyResolver does not find a key, requests are denied. Passing headers with Spring Cloud Feign. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). The RemoveRequestParameter GatewayFilter factory takes a name parameter. regexp, so green and greet would match. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. return routeBuilder.routes() It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. This predicate matches requests that happen after datetime1 and before datetime2. Note that the $ should be replaced with $\ because of the YAML specification. If the new named header already exists, its values are augmented with the new values. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. .metadata(CONNECT_TIMEOUT_ATTR, 200); 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. Retrieving the Routes Defined in the Gateway, 15.5. The following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). The following examples show how to set up global pre- and post-filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. It must be a Java System Property, not a Spring Boot property. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. This filter works only with HTTP (including HTTPS) requests. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). A utility method (called get) is available to make access to these variables easier. For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. The following describes an alternative style gateway. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). response Header Transformations: . To configure per-route timeouts: 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). In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, 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. Modifying the Way Remote Addresses Are Resolved, 5.12. Have a question about this project? The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. The name and argument names are listed as code in the first sentence or two of each section. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response.
