windows Nginx WebSocket ws协议反向代理

• 正常连接WebSocket
• 使用Nginx反向代理

未使用nginx反向代理

var ws = new WebSocket("ws://10.134.10.19:7771/chat?userId="+username);

nginx配置文件添加如下内容
注意：我nginx监听80端口连接websocket失败，换其他端口正常，原因不详

server {
	listen 7772;
	server_name testserver;
	location /chat {
		proxy_pass http://10.134.10.19:7771/chat;
		proxy_read_timeout 300s;
		proxy_send_timeout 300s;
		proxy_set_header Host $host;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_http_version 1.1;
		proxy_set_header Upgrade $http_upgrade;
		proxy_set_header Connection "upgrade";
	}
}

连接websocket地址更改为

var ws = new WebSocket("ws://testserver:7772/chat?userId="+username);
