使用wiremock-docker代理多个URL

Question

我有一个利用微服务的项目。我正在尝试使用wire-mock来创建一个测试环境。

如何使用docker-compose代理多个URL。

这是我的docker-compose文件。

networks: 
    ft-simulator: 
     external: false 
services: 
    app: 
     depends_on: 
     - nginx 
     environment: 
     - SPRING_PROFILES_ACTIVE=simulator 
     - JAVA_FLAGS=-Dhttp.proxyHost=wiremock -Dhttp.proxyPort=8080 
     healthcheck: 
      interval: 1m 
      retries: 3 
      test: 
      - CMD 
      - curl 
      - -f 
      - http://localhost:8080/health 
      timeout: 10s 
     image: ft-simulator:latest 
     ports: 
      - "8080:8080" 
     networks: 
      ft-simulator: 
       aliases: 
       - bcp 
    nginx: 
     image: nginx 
     ports: 
      - "80:80" 
      - "443:443" 
     networks: 
     - ft-simulator 
    wiremock: 
     image: rodolpheche/wiremock:2.8.0-alpine 
     networks: 
     - ft-simulator 
     ports: 
      - "8081:8080" 
     volumes: 
      - "$PWD/stubs:/home/wiremock" 
     command: ["--proxy-all=http://bcp:8080, http://www.google.com"] 
version: '3.1' 

Google只是一个占位符，直到它启动。

当我跑码头工人，组成了我得到以下错误

这是不可能的代理到一个以上的目标URL在使用--proxy-all参数的同时。

您可以做的是根据传入请求，通过为每个路由创建带有代理响应的存根映射来改变代理目标，例如，

路线1：

{ 
    "request": { 
     "urlPattern": "/route1/.*" 
    }, 

    "response": { 
     "proxyBaseUrl" : "http://target-host-1.com" 
    } 
} 

路线2：

{ 
    "request": { 
     "urlPattern": "/route2/.*" 
    }, 

    "response": { 
     "proxyBaseUrl" : "http://target-host-2.com" 
    } 
} 

注意，URL路径部分将被添加到URL，所以你用代理到http://target-host-1.com/route1/whatever和http://target-host-2.com/route2/whatever请求结束。
