本地部署dify出现Internal Server Error 解决方案

dify 版本：1.5.1

该解决方案适用于docker 使用代理而不是镜像站链接的情况。

今天本地部署dify时一打开一直弹Internal Server Error

尝试了网上的解决办法和issue中的所有解决办法后发现还是没有解决，问题一直出在api容器和plugin_daemon容器之间无法通信，查看日志会看到：

requests.exceptions.HTTPError: 502 Server Error: Bad Gateway for url: http://plugin_daemon:5002/plugin/330ba873-888a-4690-9122-d8b195abbd13/management/list?page=1&page_size=100

实际到api的容器内部使用curl -v http://plugin_daemon:5002/检测连通性，发现

 Uses proxy env variable no_proxy == 'kubernetes.docker.internal,127.0.0.0/8,localhost'
* Uses proxy env variable http_proxy == 'http://host.docker.internal:7897'
*   Trying 192.168.65.254:7897...
* Connected to host.docker.internal (192.168.65.254) port 7897 (#0)

< HTTP/1.1 502 Bad Gateway
< Connection: keep-alive

问题就出在这了，容器间内部通信走了我的代理网络，外部网络根本就识别不了这个地址，所以连接失败，解决办法也很简单，修改 docker-compose.yml 文件，为 api 和 worker 服务禁用或取消代理设置。

services:
  # API service
  api:
    image: langgenius/dify-api:1.5.1
    restart: always
    environment:
      # Use the shared environment variables.
      <<: *shared-api-worker-env
      #
      # --- 添加下面这两行来禁用代理 ---
      http_proxy: ""
      https_proxy: ""
      # ---------------------------------
      #
      # Startup mode, 'api' starts the API server.
      MODE: api
      # ... 其他配置 ...

  # worker service
  # The Celery worker for processing the queue.
  worker:
    image: langgenius/dify-api:1.5.1
    restart: always
    environment:
      # Use the shared environment variables.
      <<: *shared-api-worker-env
      #
      # --- 同样在这里添加这两行 ---
      http_proxy: ""
      https_proxy: ""
      # ---------------------------
      #
      # Startup mode, 'worker' starts the Celery worker for processing the queue.
      MODE: worker
      # ... 其他配置 ...

修改完这两处，删除容器后重新docker compose down 然后再docker compose 启动后发现就没用这个问题了
