我在apache2 websocket的一期杂志上发表了4天的文章。我在ApacheTomcat10上部署了一个连接到spring启动应用程序的SockJSWebSocket。下面是部署在tomcat上的sockjs代码。

var urlToCall='http://192.168.50.130:8082/MyWebsocket';
            console.log('calling '+urlToCall);
           websocket = new SockJS(urlToCall);

sockjs应用程序托管在dc文件夹下，因此当我访问http://192.168.50.130:8080/dc/ .与websocket的连接已建立良好。
现在，我将apache2配置为将所有请求转发到tomcat one：
以下是apache2（000 default.conf）的配置

<VirtualHost *:80> 
  ProxyPreserveHost On 

ProxyRequests Off
   ProxyPass /  http://192.168.50.130:8080/dc/ nocanon
     ProxyPassReverse /   http://192.168.50.130:8080/dc/

ProxyPass "/ws/"  "ws://192.168.50.130:8082/"
ProxyPass "/wss/"  "wss://192.168.50.130:8082/"

</VirtualHost>

不幸的是，它说总是无法连接到服务器。

这是apache2服务器的完整日志
