我正在尝试让webpack-dev-server在Docker容器内运行,然后通过Nginx主机访问它.最初的index.html加载,但与dev服务器的Web套接字连接无法连接.
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;
}
}
最佳答案
代理传递应该是你的webpack-dev-server容器的ip和端口,你需要关闭proxy_redirect;
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webpack-dev中间件
watchOptions: {
aggregateTimeout: 300,poll: 1000
}
