带有apache代理的Socket.io

Question

我试图用apache设置proxyng,以便能够在我的nodejs应用程序中使用socket.io.但我在客户端收到此错误消息:

WebSocket connection to 'wss://example.com/tools/socket.io/?EIO=3&transport=websocket&sid=eOGwJSC14TTWhHRMAAAR' failed: Error during WebSocket handshake: Unexpected response code: 400

继承我的apache配置:

     <VirtualHost *:443>
            ServerName example.com
            ServerAlias example.com
            #SSLRequireSSL
            SSLProtocol all -SSLv2  -SSLv3
            SSLCompression off
            SSLHonorCipherOrder on
            SSLEngine on
            SSLCertificateFile /etc/ssl/main.pem
            SSLCertificateKeyFile /etc/ssl/dec_ssl.key
            SSLCertificateChainFile /etc/ssl/sub.class1.server.ca.pem
            SSLCACertificateFile /etc/ssl/main.pem
            SSLProxyEngine On

            ProxyPreserveHost On
            ProxyRequests off
    </VirtualHost>

    <Location /tools/>
            ProxyPass http://localhost:8181/
            ProxyPassReverse http://localhost:8181/
    </Location>

这是客户端代码:

socket = io.connect("https://example.com",{path:'/tools/socket.io'});
socket.on("connect", function () {
    console.log("socketio Connected to server!");
});

还有什么我需要添加到apache配置来摆脱这个错误？

编辑:我的apache版本:服务器版本:Apache/2.4.6(CentOS)

我已在Apache 2.4.16中成功使用了此功能，较旧的版本可能无法正常工作。

<VirtualHost *:443>
        ServerName example.com
        ServerAlias example.com
        #SSLRequireSSL
        SSLProtocol all -SSLv2  -SSLv3
        SSLCompression off
        SSLHonorCipherOrder on
        SSLEngine on
        SSLCertificateFile /etc/ssl/main.pem
        SSLCertificateKeyFile /etc/ssl/dec_ssl.key
        SSLCertificateChainFile /etc/ssl/sub.class1.server.ca.pem
        SSLCACertificateFile /etc/ssl/main.pem
        SSLProxyEngine On

        ProxyPreserveHost On
        ProxyRequests off
</VirtualHost>

<Location /tools/>
        RewriteEngine On
        RewriteCond %{REQUEST_URI}  ^/tools/socket.io            [NC]
        RewriteCond %{QUERY_STRING} transport=websocket    [NC]
        RewriteRule "^/tools/socket.io"           "ws://localhost:8181/socket.io/" [P,L]

        ProxyPass http://localhost:8181/
        ProxyPassReverse http://localhost:8181/
</Location>

ProxyPass will not handle websocket upgrades. So, what you want to do is redirect those requests to ws://

I think in general you should not be using Location to handle this, but this config should work for you.
