## 一、如何mock一个接口 ##

看见这个界面就是简单的配置完成啦~

在这里可以调用我们之前配置的mock服务，点击send后能看到我们配置的response body

### 代码调用接口 ###

我这里是使用的SpringCloud的`@FeignClient`调用

@FeignClient(url = "https://ea6d6f75-9537-4701-ad88-54d1de82f4ba.mock.pstmn.io", name = "demo")
    public interface DemoClient {
    
        @GetMapping("/my/path1")
        Map<String, Object> func();
    }

但是！执行报错：  
feign.codec.DecodeException: Could not extract response: no suitable HttpMessageConverter found for response type \[\*\*\*\] and content type \[text/html;charset=utf-8\]

Caused by: org.springframework.web.client.UnknownContentTypeException: Could not extract response: no suitable HttpMessageConverter found for response type \[\*\*\*\] and content type \[text/html;charset=utf-8\]

大概翻译翻译就是之前mock的服务默认的content type是\[text/html;charset=utf-8\]。也就是被当成是html的字符串了，只能返回String。而我在这里想用的map来接收，或者用一个pojo类来接收，都无法从字符串转换过来，而是需要一个json。

那么怎么让mock服务返回一个json对象呢？postman在Collections页签下提供了方法。详情入下：

### 二、如何详细设置mock的请求与返回 ###

在这个界面可以修改之前配置的mock服务的request和response。

之前在mock service界面只是简单的配置了respons的body。在这个界面不仅可以修改之前配置的body，还能修改request和response的header。

在response的header里，增加一项配置`Content-Type`: `application/json`，保存一下。

再重新在代码内调用一下，已经能正常接收到了
