使用jmeter测试jsf-spring应用程序ajax请求

我使用jmeter来检查从按下客户端上的a4j按钮到服务器应答需要多长时间

为了实现这一点，我使用fiddler打开了一个HTTP请求，并查找：

ajax请求对其进行解码并将其插入http头中的值

为了发送请求，我还应该插入什么？会话ID？如何将其插入http头

我在运行Tomcat的同一台机器上运行它，我可以在Eclipse日志中看到我进入了正确的页面，但是按钮没有按下，有人能帮我吗

这是我在Eclipse中看到的记录器：

编辑：我认为这可能有助于理解我的问题：

如果您不确定AJAX调用成功需要什么，最简单的方法是使用HTTP代理并记录操作。这将为您提供传递给服务器的所有参数，以及它们在记录时的值

然后，在适当的情况下，将参数值设置为动态的（sessionID就是一个很好的例子）

你试过我的建议了吗？如果是，你得到了什么结果？
