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
