在 Apache 中，如何配置到 socket.io 的子 URL 重定向？

我有一个简单的 node.js websocket 服务器：

var io = require('socket.io')(12345);

io.on('connection', function(socket){
  console.log('a user connected');
  socket.on('disconnect', function(){
    console.log('user disconnected');
  });

  socket.on('test', function(msg){
    console.log('test msg: ' + msg);
    io.emit('test', 'Test answer');
  });
});

我连接到它，它使用 iocat 正确响应：

me@whatever:~/prj/client$ iocat --socketio ws://localhost:12345 -e test
> adsa
> [ 'Test answer' ]

所以现在我想配置 apache 服务器的 ssl 以将我的项目中的某个子 url 重定向到这个 websocket

我已经将 Apache 配置为在https://localhost/prj

我希望 websocket 可以在https://localhost/prj/socket

因此，我搜索了网络，找到了两种可能的方法来做到这一点：

1 – 仅使用 ProxyPass

<Location /prj/socket>
    ProxyPass ws://localhost:12345
    ProxyPassReverse ws://localhost:12345
</Location>

2- 带重写的 ProxyPass

<Location /agora/socket>
         RewriteEngine On
         RewriteCond %{REQUEST_URI}  ^/agora/socket/socket.io           [NC]
         RewriteCond %{QUERY_STRING} transport=websocket    [NC]
         RewriteRule ^/agora/socket/(.*)           "ws://localhost:12345/$1" [P,L]

         ProxyPass        /agora/socket/socket.io  ws://localhost:12345/socket.io
         ProxyPassReverse /agora/socket/socket.io  ws://localhost:12345/socket.io
</Location>

但这些都不起作用。连接已建立，但服务器没有响应：

me@whatever:~/prj/client$ iocat --socketio https://localhost/prj/socket -e teste
> asdfasd
> asdasd
>

我获得此信息的页面：

https://stackoverflow.com/questions/27526281/websockets-and-apache-proxy-how-to-configure-mod-proxy-wstunnel

日志中没有错误，只是无法正常工作。因此，增加了 Apache LogLevel 以查看规则是如何被重写的。我将其设置为LogLevel alert rewrite:trace6。之后，我在 Web 服务器连接中获得了此日志：

据我所知，重写规则正在应用。有人知道为什么服务器没有响应吗？

任何帮助都值得感激。谢谢。

答案1

最简单的东西往往最难找到:)

我用第一个解决方案解决了这个问题（仅使用 ProxyPass）：

<Location /prj/socket/>
        ProxyPass        http://localhost:12345/a
        ProxyPassReverse http://localhost:12345/
</Location>

唯一的问题是我使用的是 ws:// 协议。当我改用 http:// 时，它工作正常。感谢所有愿意看的人 :)
