您好我正在尝试将nginx配置为websockets的反向代理。我将服务器配置如下:
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;
}
}
但我从客户端收到错误,如下面的
与'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'
我可能正在做一些配置错误,但我看不到它。
客户端的请求标头正在关注
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==

Upgrade: websocket
Sec-WebSocket-Extensions: x-webkit-deflate-frame
Cache-Control: no-cache
Connection: Upgrade

当我进行正常的直接连接时,我的连接正常。这是工作请求标题。

此问题与nginx版本有关。请检查nginx -v,检查您的版本。 1.4 版本支持以下参数。
# WebSocket support (nginx 1.4)
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
如果您使用的是ubuntu,可以使用以下步骤安装更新版本:
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/+archive/development):
sudo add-apt-repository ppa:nginx/development
sudo apt-get update
sudo apt-get install nginx
