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

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

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

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，作为我的虚拟主机和我的Node.Js应用（使用Socket.io v1.4.5）的代理。

我的域名（API.tribeez.net）通过CloudFlarebuild立， CloudFlare 刚刚宣布了完整的WebSocket 支持 （包括通过SSL，即wss:// ）。

如何使Nginxredirect基于头的值？

如何禁止通过IP地址直接访问网站

如何使用django-sslify在我的Django + Nginx + gunicorn web应用上强制使用https，并依靠Cloudflare的新的免费SSL？

在使用Nginx和CloudFlare时，如何将真实IP传递给Gunicorn？

Laravel 5和Cloudflare SSL

当我在Chrome（v50.0）中启动我的应用程序时，我看到Chrome的networking面板中的WebSocket连接（状态pending ）。 但一分钟后，WebSocket断开（状态101 Switching Protocols ），控制台抛出一个混乱的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

当打开socket.iodeBUGging，这是我得到：

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 / Fri,06 May 2016 02:23:37 GMT socket.io:socket socket connected - writing packet Fri,06 May 2016 02:23:37 GMT socket.io:socket joining room /#L43EOXmwsqkgCMVJAAAD Fri,06 May 2016 02:23:37 GMT socket.io:clIEnt writing packet {"type":0,"nsp":"/"} Fri,06 May 2016 02:23:37 GMT socket.io-parser enCoding packet {"type":0,06 May 2016 02:23:37 GMT socket.io-parser encoded {"type":0,"nsp":"/"} as 0 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的日志：

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"

而我的Nginx conf这个应用程序：

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; } }

任何想法为什么它closures？ 难道是我需要定期Ping它？

白名单cloudflare启用ngx_http_realip_module的Ips

Cloudflare随机错误302redirect

在cloudflare上运行一个长的PHP脚本给了我一个超时（使用Nginx）

通过SSL的WebSocket：Cloudflare

不可能使用CloudFlare为WebP图像提供服务？

在Nginx blogpost底部找到答案：我需要将我的Nginx版本升级到1.3.13+。 使用正确的Nginx Debian仓库（ 见说明 ）安装1.10（最新的稳定），它现在似乎工作正常:)

Socket.io似乎打开一个投票连接，但暂停它喜欢websocket一旦后者工作（我想…）
