前我有我的節點的應用程序運行在端口3000 然後我使用nginx的反向代理與我的域名的SSL服務應用程序:Socket.io不Nginx的反向代理工作中的Node.js
server {
listen 443 ssl;
ssl_certificate /etc/nginx/ssl/server.chain.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
server_name example.com;
location/{
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
我初始化我在客戶端套接字這一行:
var socket = io.connect('https://example.com/');
而在服務器端使用此行:
var io = socket_io()
app.io = io
但是,當我啓動我的應用我有這個錯誤:
WebSocket connection to 'wss://example.com/socket.io/?EIO=3&transport=websocket&sid=jVNRhDOYJD20l9U-AAAA' failed: Error during WebSocket handshake: Unexpected response code: 502
你知道如何解決這個問題?
