MockServer和Okhttp:body类型MISSMATCH(JSON vs String)

Question

hi stack溢出社区！

我正在尝试在某些Java集成测试中模拟微服务。

要这样做，我正在使用Mockserver版本5.5.1。要进行其余的请求，我正在使用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，当我与匹配器相连时：

 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));

我得到了一个 request didn't match expectation because: body didn't match，其中尸体之间的区别是：

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：

• 假定由于类型"JSON"＆lt; -> "STRING"，身体不匹配吗？
• 这是对模型服务器的错误解释，还是OKHTTP生成错误的请求？（请求本身确实有效）
• 有什么建议如何解决此问题？

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);
}
