Question

嗨，Stack Overflow社区！

我正在尝试在某些Java集成测试中模拟微服务。

为此，我正在使用MockServer版本5.5.1。要执行其余请求，我使用的是OkHttp版本3.13.1

java中的代码：

final SomeDTO requestObject = new SomeDTO(someParams);
final String jsonObject = objectMapper.writeValueAsString(requestObject);
final MediaType MEDIA_TYPE_JSON = MediaType.get("application/json; charset=utf-8");

final RequestBody requestBody = RequestBody.create(MEDIA_TYPE_JSON, jsonObject);
final Request request = new Request.Builder().url("serverUrl").post(requestBody).build();

final Response response = client.newCall(request).execute();
final String responseJson = response.body().string();
final ResultDTO result = objectMapper.readValue(responseJson, ResultDTO.class);

这很好。但是，当我用匹配器附加MockServer时：

 final MockServerClient client = new MockServerClient("127.0.0.1", 1080);
 client.when(request().withMethod("POST") //
                      .withPath("serverUrl") //
                      .withBody(json(correctJsonString, MatchType.ONLY_MATCHING_FIELDS))) //
       .respond(response().withStatusCode(200) //
                          .withHeaders(new Header("Content-Type", "application/json; charset=utf-8"),
                                        new Header("Cache-Control", "public, max-age=86400"))
                          .withBody(responseJson));

我得到一个request didn't match expectation because: body didn't match，它们之间的区别是：

请求：

"body" : {
  "type" : "STRING",
  "string" : "{\"id\":33611,\"prop1\":28,\"prop2\":\"value2\",\"graph\":[...]}",
  "contentType" : "text/plain; charset=utf-8"
}

请求应匹配：

"body" : {
  "type" : "JSON",
  "json" : "{\"prop2\":\"value2\",\"prop1\":28,\"graph\":[...]}"
}

所以我的问题：

假设由于类型"JSON" <-> "STRING"导致主体不匹配是正确的吗？
这是对MockServer的错误解释还是OkHttp生成了错误的请求？（请求本身确实有效）
关于如何解决此问题的任何建议？

这是一个JSON演示：

    @Test
public void testRemote3() {
    String host = "localhost";
    int port = 1080;
    String url = String.format("http://%s:%d",host,port);
    MockServerClient mockServerClient = new MockServerClient(host,port);
    mockServerClient.when(
            request()
                    .withMethod("POST")
                    .withPath("/order/completed/notify")
                    .withBody(new JsonBody("{\"username\":\"foo1\", \"age\": 13}", Charset.forName("UTF-8"),MatchType.STRICT))
    ).respond(
            response().withStatusCode(200)
                    .withCookie("sessionId", "2By8LOhBmaW5nZXJwcmludCIlMDAzMW")
                    .withHeader("Location", "https://www.mock-server.com")
                    .withBody("{\"username\":\"wang\", \"status\": 1}")
    );
    mockServerClient.when(
            request()
                    .withMethod("POST")
                    .withPath("/order/completed/notify")
                    .withBody(new JsonBody("{\"username\":\"zhao\", \"age\": 3}", Charset.forName("UTF-8"),MatchType.STRICT))
    ).respond(
            response().withStatusCode(200)
                    .withCookie("sessionId", "2By8LOhBmaW5nZXJwcmludCIlMDAzMW")
                    .withHeader("Location", "https://www.mock-server.com")
                    .withBody("{\"username\":\"wang\", \"status\": true}")
    );
    log.info("----------------->calling ");
    Map<String,Object> userInfo = new HashMap<>();
    userInfo.put("age",13);
    userInfo.put("username","foo1");
    String result = OkHttpUtils.postJson(url+"/order/completed/notify",userInfo);
    log.info(result);
    Map<String,Object> fool = new HashMap<>();
    fool.put("age",3);
    fool.put("username","zhao");
    result = OkHttpUtils.postJson(url+"/order/completed/notify",fool);
    log.info(result);
}

MockServer和OkHttp：正文类型不匹配（json与字符串）
