Question

我有vert.x个app-server，拥有最简单的授权，其路由如下：

router.post("/user/sign").handler(this::userSignIn);

虽然我是从GUI执行此操作，但它运行正常。

但我想为此操作创建Unit-Test。我做的代码：

@Test
public void testServerUserRegister(TestContext context) {
  HttpClient client = vertx.createHttpClient();
  HttpClientRequest request = client.post("user/sign", response -> {
  System.out.println("Some callback " + response.statusCode());
  });

  String body = "{'username':'www','password':'www'}";
  request.putHeader("content-length", "1000");
  request.putHeader("content-type", "application/x-www-form-urlencoded");
  request.write(body);
  request.end();
}

当我开始此测试时：mvn test

我看到了结果但是：

1-我没有看到任何类似的字符串＆＃34;有些回调......＆＃34;

2-我得到RejectedExecutionException：

知道我在这里做错了什么吗？

调用request.end()后，JUnit测试退出，Vert.x实例关闭（因此RejectedExecutionException）。

请记住，Vert.x API是异步的。看看Vert.x Unit section about asynchronous testing。

你应该做的是：

@Test
public void testServerUserRegister(TestContext context) {
  // Get an async object to control the completion of the test
  Async async = context.async();
  HttpClient client = vertx.createHttpClient();
  HttpClientRequest request = client.post("user/sign", response -> {
    // You may want to check response code here
    // to either complete or fail the test
    async.complete();
    System.out.println("Some callback " + response.statusCode());
  });

  String body = "{'username':'www','password':'www'}";
  request.putHeader("content-length", "1000");
  request.putHeader("content-type", "application/x-www-form-urlencoded");
  request.write(body);
  request.end();
}

vert.x：你如何正确发送帖子请求？
