帶有NGINX proxy_pass的Webpack Dev Server

Question

我正在嘗試讓webpack-dev-server在Docker容器內運行，然后通過NGINX主機訪問它。 初始index.html加載但與開發服務器的Web套接字連接無法連接。

VM47：35與'ws：//example.com/sockjs-node/834/izehemiu/websocket'的WebSocket連接失敗：WebSocket握手期間出錯：意外響應代碼：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;
  }
}

Answer 1

代理傳遞應該是你的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";
}

另外，不要忘記向您的webpack-dev中間件添加poll

  watchOptions: {
    aggregateTimeout: 300,
    poll: 1000
  }
