Question

我正在尝试使用Socket.io在我的Javascript（React）应用程序中设置WebSockets。

使用Socket.io客户端（v1.4.5）中的polling传输时，一切正常。但我想使用实际和安全的WebSockets（wss://协议）......

我的服务器是运行Nginx v1.2.1的Debian 7，作为我的虚拟主机的代理，以及我的Node.js应用程序（使用Socket.io v1.4.5）。

我的域名（api.tribeez.net）是通过CloudFlare设置的，just announced完整的WebSocket support（包括通过SSL，即wss://）。< / p>

当我在Chrome（v50.0）中启动我的应用时，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）并且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，这就是我得到的：

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: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"

我的Nginx为这个应用程序配置：

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;
    }
}

知道它关闭的原因吗？可能是我需要定期ping它吗？

在Nginx blogpost的底部找到答案：我需要将我的Nginx版本升级到1.3.13+。我使用正确的Nginx Debian存储库（see instructions）安装了1.10（最新的稳定版），这解决了这个问题。

Socket.io似乎无论如何都要打开一个轮询连接，但是一旦后者工作，我会暂停它以更喜欢websocket（我想......）

WebSocket连接失败：打开一个或多个保留位：reserved1 = 0，reserved2 = 1，reserved3 = 1
