使用 HTTP 和 WS 协议的 Apache 代理

Apache proxy with HTTP and WS protocols

我的服务器上有一个服务运行,可以通过http和ws访问它。当我要在 Apache2 中配置子域时,我遇到了两难选择,因为我想让这两种协议都为同一个子域工作。也就是说,如果传入连接使用的是 HTTP 协议(​​http://),那么 Apache2 必须将连接重定向到 SERVICE:HTTP_PORT,如果是 websocket(ws://),我希望它转到 SERVICE:WS_PORT。有什么方法可以做到这一点而不必使用 /ws 或 /websocket 之类的路由来建立连接?

我遵循了这个答案的说明:

这是我的服务器的最终 Apache2 配置:

<VirtualHost *:80>
  ServerAdmin admin@example.com
  ServerName service.example.com

  RewriteEngine On
  RewriteCond %{HTTP:Upgrade}   =websocket [NC]
  RewriteRule /(.*)     wss://service.example.com/ [P,L]
  RewriteCond %{HTTP:Upgrade}   !=websocket [NC]
  RewriteRule /(.*)     https://service.example.com/ [P,L]

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>


<VirtualHost *:443>
  ServerAdmin admin@example.com
  ServerName service.example.com

  RewriteEngine On
  RewriteCond %{HTTP:Upgrade} =websocket [NC]
  RewriteRule /(.*)           ws://localhost:1886/ [P,L]
  RewriteCond %{HTTP:Upgrade} !=websocket [NC]
  RewriteRule /(.*)           http://localhost:1996/ [P,L]
  ProxyPassReverse /          https://service.example.com

  <Location "/">
    Header set Access-Control-Allow-Origin "*"
    Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
    Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

  </Location>

  SSLEngine On
  SSLProtocol All -SSLv2 -SSLv3
  SSLHonorCipherOrder On
  SSLCipherSuite HIGH:MEDIUM

  SSLCertificateFile cert.pem
  SSLCertificateKeyFile privkey.pem
  SSLCertificateChainFile chain.pem

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

现在我可以使用 http://https://ws://wss:// 访问。
