nginx-websocket反向代理配置



嗨,我正在尝试将nginx配置为websocket的反向代理。我配置我的服务器如下:

server {
    listen       80;
    server_name  www.mydomain.com;
    access_log  off;
    #error_log off;
    location / {
        proxy_pass         http://127.0.0.1:8765;
        proxy_redirect     off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $http_host;
        proxy_buffering off;
    }
}

但我从客户端收到一个错误,比如跟踪

到"ws://www.application.com/ws"的WebSocket连接失败:WebSocket握手期间出错:"connection"标头值不是"Upgrade"

我可能做了一些配置错误,但我看不到它。

客户端的请求标头在之后

GET ws://www.talkybee.com/ws HTTP/1.1
Pragma: no-cache
Origin: http://www.talkybee.com
Host: www.talkybee.com
Sec-WebSocket-Key: Ol+O1IdaLEsHxxWRBt2oqg==
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36
Upgrade: websocket
Sec-WebSocket-Extensions: x-webkit-deflate-frame
Cache-Control: no-cache
Connection: Upgrade
Sec-WebSocket-Version: 13

当我进行正常的直接连接时,我的连接会正常工作。这是工作请求标头。

Cache-Control:no-cache
Connection:Upgrade
Host:www.talkybee.com:8765
Origin:http://www.talkybee.com:8765
Pragma:no-cache
Sec-WebSocket-Extensions:x-webkit-deflate-frame
Sec-WebSocket-Key:Y026b/84aUkMxVb0MaKE2A==
Sec-WebSocket-Version:13
Upgrade:websocket
User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36

这个问题与nginx版本有关。请检查nginx-v,以检查您的版本。1.4版本之后支持以下参数。

 # WebSocket support (nginx 1.4)
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "upgrade";

如果你正在使用ubuntu,你可以通过以下步骤安装一个新版本:

首先删除旧版本(https://askubuntu.com/questions/235347/what-is-the-best-way-to-uninstall-nginx):

sudo apt-get remove nginx
sudo apt-get purge nginx
sudo apt-get autoremove 

然后安装新版本(https://launchpad.net/~nginx/+归档/开发):

sudo add-apt-repository ppa:nginx/development
sudo apt-get update
sudo apt-get install nginx
