apache - 如何在运行Apache的端口443上运行socket.io？

Question

我需要在端口443上运行socket.io(其中apache用“让我们加密”运行https站点)

这个想法是使用一个Apache代理，它将流量重定向到socket.io端口。
我找到了解决方案:

<VirtualHost *:443>
     ServerName mysite.com
     ServerAlias www.mysite.com

     SSLEngine on
     SSLProxyEngine On
     ProxyRequests Off

     SSLCertificateFile /etc/apache2/ssl/mysite.com.crt
     SSLCertificateKeyFile /etc/apache2/ssl/mysite.com.key
     SSLCertificateChainFile /etc/apache2/ssl/ca.cer

     DocumentRoot /var/www/errorPages

     ErrorDocument 503 /503.html
     ProxyPass /503.html !

     ProxyPass / http://localhost:3999/
     ProxyPassReverse / http://localhost:3999/

RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* ws://localhost:3999%{REQUEST_URI} [P]

</VirtualHost>

我在端口3999上运行socket.io
HTTPS站点运行正常，但是出现了HTTP 404错误。
我猜问题出在rewriteCond上。

websocket.js:112 WebSocket connection to 'wss://mysite.com/socket.io/?id=11518237&username=john failed: Error during WebSocket handshake: Unexpected response code: 404

试试mod_proxy_wstunnel
It provides support for the tunnelling of web socket connections to a backend websockets server. The connection is automatically upgraded to a websocket connection
