我正在尝试在Node js应用程序中使用socket.io。我将应用程序放在子域上,并且前端运行在域的www版本上。
不能在同一域上运行前端和Node js服务。
从客户端到服务器来回发送数据似乎正在起作用。我已经通过两种方式发送数据,但它运行良好。
但是,在浏览器的控制台中,我收到以下错误。
WebSocket connection to 'wss://subdomain.domain.com/socket.io/?EIO=3&transport=websocket&sid=6bNHWyXcCdlMI0HHAAAB' failed: Error during WebSocket handshake: Unexpected response code: 400
我的Nginx配置如下所示:
# HTTP - redirect all requests to HTTPS:
server {
listen 80;
listen [::]:80 default_server ipv6only=on;
return 301 https://$host$request_uri;
}
# HTTPS - proxy requests on to local Node.js app:
server {
listen 443;
server_name subdomain.domain.com;
ssl on;
# Use certificate and key provided by Let's Encrypt:
ssl_certificate /etc/letsencrypt/live/subdomain.domain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/subdomain.domain.com/privkey.pem;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers '*******';
# Pass requests for / to localhost:3000:
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://localhost:3000/;
proxy_ssl_session_reuse off;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Connection "upgrade";
}
}
客户端和Node js都使用https。
有谁知道是什么导致了这个问题以及如何修复它?
谢谢

您好像忘了升级标头了。如果您想将Nginx用作WebSockets的反向代理,则需要它。
如上所述here,只需尝试添加一个标头:
proxy_set_header Upgrade $http_upgrade;
