The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. 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. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. GitHub Gist: instantly share code, notes, and snippets. The 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. SetResponseHeader is aware of URI variables used to match a path or host. If You Appreciate This, You Can Consider: We are thankful for your never ending support. The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. By default, it creates a NettyChannel by using the default TrustManagerFactory. public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. If it is not matched, the filter does nothing. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. return routeBuilder.routes() The RemoteAddr Route Predicate Factory, 5.10.1. This could be useful for maintenance windows. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. The RemoveRequestHeader GatewayFilter factory takes a name parameter. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. httpStatusCode: The HTTP Status of the request returned to the client. It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. Passing headers with Spring Cloud Feign. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. The RemoveResponseHeader GatewayFilter factory takes a name parameter. The default is http|https|ftp|ftps. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. None of the prior documentation applies to what follows. For example, you can match on the path segment of the URL or the HTTP method of the request. 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. You can combine multiple route predicate factories with logical and statements. The pattern is an Ant-style pattern with . If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. APIcast standard policies connect-timeout must be specified in milliseconds. AddResponseHeader is aware of URI variables used to match a path or host. . The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. Creating and Deleting a Particular Route, 15.8. A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. For example, to reference a filter named Something in configuration files, the filter You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. privacy statement. AddRequestHeader is aware of the URI variables used to match a path or host. The Host route predicate factory takes one parameter: a list of host name patterns. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled Naming Custom Filters And References In Configuration, 18. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. The url parameter should be a valid URL. All pre filter logic is executed. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. This applies the filter to all requests. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; 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. Writing Custom Route Predicate Factories, 17.2. This uses Java regular expressions for a flexible way to rewrite the request path. You can extend an abstract class called AbstractGatewayFilterFactory. 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. 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. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. Those values are then available for use by GatewayFilter factories. name can contain a space-separated list of header names. Spring Cloud Gateway. Already on GitHub? the ID of the service from the DiscoveryClient. 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. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. . AS_IN_REQUEST: The version is stripped only if the original request path contains no version. Spring Cloud Gateway includes many built-in route predicate factories. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. CircuitBreaker also supports URI variables in the fallbackUri. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. 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. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. It is the name of the query parameter to be removed. 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. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. 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. let's see. .application.yml. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. 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. 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 response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. 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. This is the value of the Location header. I think i have to go for a blocking call here. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. which are java ZonedDateTime objects. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. Download ZIP. Sharing Routes between multiple Gateway instances, 17.1. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. returned from the route it wraps. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. Closing due to lack of requested feedback. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. You can configure the logging system to have a separate access log file. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. You can read more about them in the. The SetRequestHeader GatewayFilter factory takes name and value parameters. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. essentially skipping the filter. 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. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. 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 following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. it is proxying. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. 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'. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. 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. Refresh the page, check Medium 's site status, or find something interesting to read. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. The predicates defined by RouteDefinitionLocator beans are combined using logical and. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. You can also define a rate limiter as a bean that implements the RateLimiter interface. While a Gateway is running you can use kubectl scale to modify the number of replicas. URI variables may be used in the value and are expanded at runtime. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. To write a custom global filter, you must implement GlobalFilter interface as a bean. The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. Policy to specify how to modify the response code, body and headers. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. 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. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. The RemoveHopByHop Headers Filter removes headers from forwarded requests. 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) The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request. Once a request has been marked as routed, other routing filters will not route the request again, The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). 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 up for a free GitHub account to open an issue and contact its maintainers and the community. as the separator. URI variables may be used in the value and are expanded at runtime. 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 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 this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. Otherwise, the original value in the client request is sent. 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"). The KeyResolver is a simple one that gets the user request parameter To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The resulting response is similar to the following: The response contains the details of the global filters that are in place. AddRequestParameter is aware of the URI variables used to match a path or host. Displays information about a particular route. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. The following examples show how to set up global pre- and post-filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. This section covers common problems that may arise when you use Spring Cloud Gateway. Writing Custom GatewayFilter Factories, 17.2.1. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. For a full working sample see this project. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. ServerHttpResponse interface. Retrieving Information about a Particular Route, 15.6. Configure for High Availability. Any otherway is there apart from blocking call? Acompanhe-nos: can gabapentin help with bell's palsy Facebook If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. GatewaySampleApplication.java. The ServerHttpResponse instance is used to . The path part of the request URL is overridden with the path in the forward URL. The following example below is invalid: The Redis implementation is based on work done at Stripe. For the external controller/handler scenario, headers can be added with exception details. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. }) By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. 1. The request returns a 200 without a response body. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Spring cloud gateway response body modification. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. 4.1. 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). HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. 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.) Factory takes name and value parameters headers filter removes headers from forwarded requests for Cloud.
