`SetRequestHostHeader` 過濾器

在某些情況下，可能需要覆蓋主機頭。在這種情況下，SetRequestHostHeader 過濾器可以將現有的主機頭替換為指定值。該過濾器接受一個 host 引數。以下列表配置了一個 SetRequestHostHeader 過濾器。

application.yml

spring:
  cloud:
    gateway:
      mvc:
        routes:
        - id: set_request_host_header_route
          uri: https://:8080
          predicates:
          - Path=/headers
          filters:
          - name: SetRequestHostHeader
            args:
              host: example.org

GatewaySampleApplication.java

import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.uri;
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.setRequestHostHeader;
import static org.springframework.cloud.gateway.server.mvc.handler.GatewayRouterFunctions.route;
import static org.springframework.cloud.gateway.server.mvc.handler.HandlerFunctions.http;

@Configuration
class RouteConfiguration {

    @Bean
    public RouterFunction<ServerResponse> gatewayRouterFunctionsSetRequestHostHeader() {
        return route("set_request_host_header_route")
            .GET("/headers", http())
            .before(uri("https://:8080"))
            .before(setRequestHostHeader("example.org"))
            .build();
    }
}

SetRequestHostHeader 過濾器將主機頭的值替換為 example.org。
