使用wiremock-docker代理多個URL

Question

我有一個利用微服務的項目。我正在嘗試使用wire-mock來創建一個測試環境。

如何使用docker-compose代理多個URL。

這是我的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只是一個佔位符，直到它啓動。

當我跑碼頭工人，組成了我得到以下錯誤

這是不可能的代理到一個以上的目標URL在使用--proxy-all參數的同時。

您可以做的是根據傳入請求，通過爲每個路由創建帶有代理響應的存根映射來改變代理目標，例如，

路線1：

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

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

路線2：

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

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

注意，URL路徑部分將被添加到URL，所以你用代理到http://target-host-1.com/route1/whatever和http://target-host-2.com/route2/whatever請求結束。
