Webpack开发服务器与NGINX proxy_pass

Question

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加载，但是Web Sockets连接到开发服务器无法连接。

VM47:35 WebSocket连接到'ws://example.com/sockjs-node/834/izehemiu/websocket'失败:WebSocket握手时错误:意外响应码:400

我使用以下配置:

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;
  }
}

代理通道应该是你的webpack-dev-server容器的ip和端口，你需要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";
}

不要忘记在你的webpack-dev中间件中添加poll

  watchOptions: {
    aggregateTimeout: 300,
    poll: 1000
  }
