如何在Java中捕获HTTP请求并模拟其响应?
假设Java应用程序向如何在Java中捕获HTTP请求并模拟其响应?,java,http,mocking,wiremock,http-mock,Java,Http,Mocking,Wiremock,Http Mock,假设Java应用程序向http://www.google.com/...而且无法配置继承的库(在内部发出此类请求),因此我无法存根或替换此URL 请分享一些最佳实践来创建一个类似模拟的 whenCalling(“http://www.google.com/some/path“”。使用方法(“GET”)。然后使用ExpectResponse(“HELLO”) 因此,在当前JVM进程的上下文中,任何HTTP客户端对该URL发出的请求都将被重定向到mock,并替换为该响应“HELLO” 我试图用Wir

而且无法配置继承的库(在内部发出此类请求),因此我无法存根或替换此URL
请分享一些最佳实践来创建一个类似模拟的
whenCalling(“http://www.google.com/some/path“”。使用方法(“GET”)。然后使用ExpectResponse(“HELLO”)
因此,在当前JVM进程的上下文中,任何HTTP客户端对该URL发出的请求都将被重定向到mock,并替换为该响应“HELLO”
我试图用WireMock、Mockito或Hoverfly找到一个解决方案,但它们似乎做了一些不同的事情。也许我只是没能正确地使用它们
您能否从main
方法中显示一个简单的设置,如:
以下是如何通过以下方法实现您想要的 该示例演示了将嵌入式API模拟器配置为Spring的RestTemplate客户端的HTTP代理的两种不同方法。请参阅(问题中的引语)“继承库”的文档,通常基于Java的客户端依赖于所描述的系统属性,或者可能提供一些方法来使用代码配置HTTP代理

如果您无法控制代码,则可能需要在操作系统级别上重写调用太棒了!这可能比我想象的还要好。您能否在答案中添加maven依赖项,这是在项目中使用API模拟器所必需的?在那之后,答案将是完整的,我将接受它。Hi@diziaq——编辑了答案,添加了关于如何将嵌入式API模拟器作为依赖项添加到maven管理的项目的信息。你应该看看真正的主力-独立API模拟器:-)干杯
