Question

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技术与客户端进行通信。因此，当我在客户端尝试超过150个并发用户时，我收到此异常，我不知道服务器想要说什么。

Answer 1

您必须遵循在浏览器客户端上遵循的相同规则

在您的客户端，您可能已添加以下代码

$ 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，所以气氛并不是你的请求。在java方面，首先你要做大气连接，然后你必须解雇你的请求......

Answer 2

最可能的原因是，如果不使用“websocket”，您可能没有客户端URL：

“ws：//”+ HOST +“：”+ PORT +“/ websocket”

如果在与服务器通信时错过/ websocket客户端代码，则会出现此异常

无效的握手响应异常
