找不到Mockserver请求

Question

我目前正在尝试创建期望，并通过mockServer (可以在here中找到)验证它们。

我已经看过他们的文档好几次了，但是我找不到为什么我的期望验证失败了。这是我的代码

    @Rule
    public MockServerRule mockServerRule = new MockServerRule(this, 9000);

    private MockServerClient mockServer;

    @Test
    public void testVerification() {
        mockServer.when(
                HttpRequest.request()
                  .withMethod("POST")
                  .withPath("/validate")
                  .withHeader("\"Content-type\", \"application/json\"")
                  .withBody("{username: 'foo', password: 'bar'}"))
                  .respond(
                      HttpResponse.response()
                        .withStatusCode(401)
                        .withHeaders(
                          new Header("Content-Type", "application/json; charset=utf-8"),
                          new Header("Cache-Control", "public, max-age=86400"))
                        .withBody("{ message: 'incorrect username and password combination' }")
                        .withDelay(TimeUnit.SECONDS,1)
                    );

        mockServer.verify(HttpRequest.request().withMethod("POST")
                  .withPath("/validate")
                  .withBody("{username: 'foo', password: 'bar'}"),
                VerificationTimes.exactly(1));
    }

在尝试验证时，我总是收到错误消息

java.lang.AssertionError: Request not found exactly once, expected:<{
  "method" : "POST",
  "path" : "/validate",
  "body" : "{username: 'foo', password: 'bar'}"}> but was:<>

好吧，你忘了向你的模拟服务器发送一个请求。您只是模拟了它的行为，然后检查服务器是否已被调用，但您错过了调用。

用下面这样的方式试试：

public int callValidateUrl() throws IOException {
    URL url = new URL("http://localhost:9000/validate");

    HttpURLConnection con = (HttpURLConnection) url.openConnection();
    con.setRequestMethod("POST");
    con.setRequestProperty("Content-Type", "application/json");

    con.setDoOutput(true);
    String jsonInputString = "{username: 'foo', password: 'bar'}";
    try (OutputStream os = con.getOutputStream()) {
        byte[] input = jsonInputString.getBytes("utf-8");
        os.write(input, 0, input.length);
    }

    return con.getResponseCode();
}

如果你使用的是Spring，RestTemplate更容易使用。
