【问题描述】：
我正在尝试使用 Socket.io 在我的 Javascript (React) 应用程序中设置 WebSocket。
从 Socket.io 客户端 (v1.4.5) 使用 polling 传输时，一切正常。
但我想使用实际且安全的 WebSockets（wss:// 协议）...
我的服务器是 Debian 7，运行 Nginx v1.2.1 作为我的虚拟主机和我的 Node.js 应用程序的代理（使用 Socket.io v1.4.5）。
我的域名（api.tribeez.net）是通过CloudFlare设置的，其中just announced完整的WebSocketsupport（包括通过SSL，即wss://）。
当我在 Chrome (v50.0) 中启动我的应用程序时，我在 Chrome 的网络面板中看到了 WebSocket 连接（状态 pending）。
但一分钟后，WebSocket 断开连接（状态 101 Switching Protocols），控制台让我感到困惑 WebSocket connection to 'wss://api.tribeez.net/socket.io/?EIO=3&transport=websocket&t=LI3t1dh' failed: One or more reserved bits are on: reserved1 = 0, reserved2 = 1, reserved3 = 1
打开socket.io调试时，我得到的是这样的：
Fri, 06 May 2016 02:23:37 GMT socket.io:server incoming connection with id L43EOXmwsqkgCMVJAAAD
Fri, 06 May 2016 02:23:37 GMT socket.io:client connecting to namespace /
Fri, 06 May 2016 02:23:37 GMT socket.io:namespace adding socket to nsp /

Transport=websocket, query=/socket.io/?EIO=3&transport=websocket&t=LI3t1dh
Fri, 06 May 2016 02:23:37 GMT socket.io:socket joined room /#L43EOXmwsqkgCMVJAAAD
Fri, 06 May 2016 02:23:37 GMT socket.io:socket joining room tribe#1
Fri, 06 May 2016 02:23:37 GMT socket.io:socket joined room tribe#1
Fri, 06 May 2016 02:24:37 GMT socket.io:client client close with reason transport close
Fri, 06 May 2016 02:24:37 GMT socket.io:socket closing socket - reason transport close
这是 Nginx 日志：
2016/05/06 04:24:37 [error] 28383#0: *549 upstream timed out (110: Connection timed out) while reading upstream, client: xxx.xxx.xxx.xxx, server: api.tribeez.net, request: "GET /socket.io/?EIO=3&transport=websocket&t=LI3t1dh HTTP/1.1", upstream: "http://127.0.0.1:3010/socket.io/?EIO=3&transport=websocket&t=LI3t1dh", host: "api.tribeez.net"
还有我的这个应用程序的 Nginx conf：
http {
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
}
server {
server_name api.tribeez.net;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:3010;
}
location /socket.io/ {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://127.0.0.1:3010;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
}
知道为什么它会关闭吗？难道是我需要定期ping它？
