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，它与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configurationApache服务器的sslredirect到我的项目的某个子url到这个websocket
我有一个Apacheconfiguration为在https：// localhost / prj服务我的项目
我想在https：// localhost / prj / socket中使用websocket
所以searchnetworking，所以我find了两种可能的方式来做到这一点：
1 – 单独的ProxyPass
<Location /prj/socket> ProxyPass ws://localhost:12345 ProxyPassReverse ws://localhost:12345 </Location>
2-重写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/$1" [P,L] ProxyPass /agora/socket/socket.io ws://localhost:12345/socket.io ProxyPassReverse /agora/socket/socket.io ws://localhost:12345/socket.io </Location>
但他们都没有工作。 连接已build立但服务器不响应：
me@whatever:~/prj/client$ iocat --socketio https://localhost/prj/socket -e teste > asdfasd > asdasd >
我得到这个信息的页面：
https://github.com/socketio/socket.io/issues/1696
https://stackoverflow.com/questions/27526281/websockets-and-apache-proxy-how-to-configure-mod-proxy-wstunnel
日志中没有错误，它不会工作。 于是增加了Apache LogLevel来查看规则在哪里被重写。 我把它设置为LogLevel alert rewrite:trace6 。 之后，我得到了这个日志在web服务器连接：

AFAIU重写规则正在被应用。 任何人都知道为什么服务器没有响应？
任何帮助赞赏。 谢谢。
最简单的事情往往是最难find:)
我解决了第一个解决scheme（只使用ProxyPass）：
<Location /prj/socket/> ProxyPass http://localhost:12345/a ProxyPassReverse http://localhost:12345/ </Location>
唯一的问题是我正在使用ws：//协议。 当我改为http：//它工作正常。 感谢任何关心的人:)
