【问题描述】:
我正在尝试在 Node js 应用程序中使用 socket.io。我的应用程序位于子域上,而前端在域的 www 版本上运行。
在同一个域上运行前端和 Node js 服务不是一种选择。
从客户端到服务器来回发送数据似乎可以正常工作。我已经通过两种方式发送了数据,并且效果很好。
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。
有谁知道导致此问题的原因以及如何解决?
谢谢
