重放 LoadRunner 脚本时尝试连接到 RMIRegisty 时出现 MalformdURLException

Question

我正在尝试重放通过 RMI 对服务器客户端-服务器应用程序进行调用的负载运行程序脚本。 RMI 服务和注册表在服务器上运行良好，因为其他应用程序能够连接并正常工作。

当我尝试重放 LoadRunner 脚本时，我低于堆栈跟踪：

我看到“MalformedURLException”，但我们传递的 URL 没有问题。请帮我解决这个问题。

很可能是您的网址中未经处理的动态元素。此外，如果您没有检查 LoadRunner 脚本的每一步是否成功，那么您将面临非常高且真实的可能性，即您的业务流程在此请求之前已经偏离轨道，而您正在发出的请求是业务流程的上下文，即使对于看似格式正确的请求，也会在 100% 的情况下导致错误。

使用 web_reg_find() 或 web_reg_save_param() 检查每个步骤是否成功，以在每个返回的页面|响应上检查不同的成功。如果您没有收到预期的结果，则分支您的代码以处理不匹配情况。

如果您将检查预期结果与交叉检查处理任何将解决您的问题的动态内容结合起来，那么几率肯定很接近。
