我正在使用我们的 tomcat 服务器进行压力测试，该服务器通过 websocket 技术与其客户端进行通信。所以当我在客户端尝试超过 150 个并发用户时，我收到了这个异常，我不知道服务器想说什么。

最可能的原因是您可能没有没有“websocket”的客户端URL，例如：

"ws://"+HOST+":"+ PORT+"/websocket"

如果您在与服务器通信时错过客户端代码中的 /websocket，您将收到此异常

您必须遵循与浏览器客户端相同的规则

那是在您的客户端，您可能已经添加了以下代码

$atmosphere.subscribe(请求);

你也必须在你的 java 客户端上做同样的事情，因为你的请求没有订阅气氛，所以气氛不会验证你的请求。在 java 方面，首先你要进行气氛连接，然后你必须触发你的请求......
