httpMethod: The HTTP method used for the request. 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. Embed. 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. reverse proxies. . aws api gateway parameter mapping. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. consumer can be a pure Client (like an SSO application) or a Resource 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. Spring cloud gateway response body modification. status: The HTTP status of the request returned to the client. . This applies the filter to all requests. After the proxy request is made, the post filter logic is run. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. The first one is the This is the number of tokens taken from the bucket for each request and defaults to 1. 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)'. 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. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. status codes you want to trip the circuit breaker you can either use an integer with the status code The following example below is invalid: The Redis implementation is based on work done at Stripe. The gateway maintains a client pool that it uses to route to backends. if. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. A number of timeouts are associated with this handshake. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. It adds the Host header, scheme and port of the current request to any existing Forwarded header. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. This predicate matches requests that happen after the specified datetime. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. Tripping The Circuit Breaker On Status Codes, 12.4.1. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. 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. 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. There is an abstract class called AbstractRoutePredicateFactory which you can extend. 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]. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. The arguments are typically listed in the order that are needed for the shortcut configuration. 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. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The default request size is set to five MB if not provided as a filter argument in the route definition. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. It uses the Netty HttpClient to make the downstream proxy request. It is the name of the query parameter to be removed. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. Value 3.9. 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). Naming Custom Filters And References In Configuration, 18. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. URI variables may be used in the value and are expanded at runtime. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. You can add headers to the downstream response by using the header() methods on ProxyExchange. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. 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 RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). The url parameter should be a valid URL. It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. The ServerHttpResponse instance is used to . This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. 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. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. 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. 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. In some cases you might want to trip a circuit breaker based on the status code GatewaySampleApplication.java. .route("test1", r -> { To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). 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. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. 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. So a request to /hello is sent to /mypath/hello. Retrieving the Routes Defined in the Gateway, 15.5. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. It is the name of the header to be removed. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). Some situations necessitate reading the request body. a circuit breaker. Displays the list of GatewayFilter factories applied to a particular route. 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). Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. cloudflare tunnel home assistant 19 3407 . 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. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. forwards the incoming token to outgoing resource requests. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. . The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. It is the name of the header to be removed. 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. The Host route predicate factory takes one parameter: a list of host name patterns. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. connect-timeout must be specified in milliseconds. You can use it inside a regular Spring web handler as a method parameter. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. How does it work? If youre using load-balanced routes, you need to explicitly define your. The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. The following describes an alternative style gateway. Cleanliness 4.4. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. Since the request can be read only once, we need to cache the request body. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. and puts it in a request header for the downstream requests. URI variables may be used in the value and are expanded at runtime. Configuring Predicates and Filters For, 15.4. Currently, only forward: schemed URIs are supported. 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. value or the String representation of the HttpStatus enumeration. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. name can contain a space-separated list of header names. The RemoteAddr Route Predicate Factory, 5.10.1. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. You can configure the logging system to have a separate access log file. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). which are java ZonedDateTime objects. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). The default is http|https|ftp|ftps. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. 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 an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. AddRequestParameter is aware of the URI variables used to match a path or host. The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". 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. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Easy to extend and/or customize using standard Spring patterns return r.host("*.somehost.org").and().path("/somepath") ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. GitHub Gist: instantly share code, notes, and snippets. 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 preceding route matches if the request contained a red query parameter whose value matched the gree. A Token Relay is where an OAuth2 consumer acts as a Client and The KeyResolver is a simple one that gets the user request parameter The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). For the external controller/handler scenario, headers can be added with exception details. The args key is a map of key value pairs to configure the predicate or filter. URI variables may be used in the value and will be expanded at runtime. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. 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 JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. Each item defines the name and the arguments of a given predicate. The pattern is an Ant-style pattern with . Acompanhe-nos: can gabapentin help with bell's palsy Facebook 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. 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). When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. 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 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. NOTE: This is not recommended for production. 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. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. 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. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. 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. This uses Java regular expressions for a flexible way to rewrite the request path. The circuit breaker config object takes a list of 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]. Passing headers with Spring Cloud Feign. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. 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. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. Created 6 years ago. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. Route filters are scoped to a particular route. 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.
