带有 NGINX proxy_pass 的 Webpack 开发服务器 [英] Webpack Dev Server with NGINX proxy_pass

问题描述

我试图让 webpack-dev-server 在 Docker 容器内运行，然后通过 NGINX 主机访问它.初始 index.html 已加载，但无法连接到开发服务器的 Web Sockets 连接.

I'm trying to get webpack-dev-server running inside a Docker container then accessing it through a NGINX host. The initial index.html loads but the Web Sockets connection to the dev server cannot connect.

VM47:35 WebSocket 连接到ws://example.com/sockjs-node/834/izehemiu/websocket"失败:WebSocket 握手期间出错:意外响应代码:400

VM47:35 WebSocket connection to 'ws://example.com/sockjs-node/834/izehemiu/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400

我正在使用以下配置.

map $http_upgrade $connection_upgrade {
  default upgrade;
  ''      close;
}

upstream webpack_dev_server {
  server node;
}

server {
  server_name _;
  listen 80;
  root /webpack_dev_server;

  location / {
    proxy_pass http://webpack_dev_server;
  }

  location /sockjs-node/ {
    proxy_pass http://webpack_dev_server/sockjs-node/;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;  # pass the host header - http://wiki.nginx.org/HttpProxyModule#proxy_pass

    proxy_http_version 1.1;  # recommended with keepalive connections - http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_http_version

    # WebSocket proxying - from http://nginx.org/en/docs/http/websocket.html
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
  }
}

推荐答案

Proxy pass 应该是你的 webpack-dev-server 容器的 ip 和 port 并且你需要 proxy_redirect off;

Proxy pass should be ip and port of your webpack-dev-server container and you need proxy_redirect off;

location /sockjs-node {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header Host $host;

    proxy_pass http://node:8080; 

    proxy_redirect off;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

另外不要忘记将 poll 添加到你的 webpack-dev 中间件

Also don't forget to add poll to your webpack-dev middleware

  watchOptions: {
    aggregateTimeout: 300,
    poll: 1000
  }
