在客户端,我正在尝试建立wss连接:var ws = new WebSocket("wss://wsserver.com/test")
它返回一个错误:WebSocket connection to 'wss://wsserver.com/test' failed: Error during WebSocket handshake: Unexpected response code: 400
完整的 header 是:
请求 header
GET wss://wsserver.com/test HTTP/1.1
Host: wsserver.com
Connection: Upgrade
Pragma: no-cache
Cache-Control: no-cache
Upgrade: websocket

服务器端在Apache反向代理后面的端口8888上运行。这是Apache配置:
<VirtualHost *:443>
ServerName website.com
ProxyPreserveHost On
ProxyRequests Off
ProxyPass "/" "wss://localhost:8888/"
已安装mod_proxy和mod_proxy_wstunnel。
这里缺少什么吗?似乎请求已通过,但未建立连接。
最佳答案
我最终通过对虚拟主机使用此配置解决了此问题,该配置使用HTTP header 过滤请求:
<VirtualHost *:443>
ServerName website.com
RewriteEngine On
# When Upgrade:websocket header is present, redirect to ws
# Using NC flag (case-insensitive) as some browsers will pass Websocket
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule ^/ws/(.*) wss://localhost:8888/ws/$1 [P,L]
# All other requests go to http
ProxyPass "/" "http://localhost:8888/"
