java将asynchttpclient作为maven项目发送异步post请求并运行

Question

我在这里完全疯了。这是我第一次使用java，它让我非常害怕

无论如何，我需要做的是创建一个小型java maven项目，在其中我监听一个特定的UDP端口（python脚本atm，模拟我应该使用的设备），然后在发送一个post请求到一个带有两个post参数的特定url之前做一些事情

我发现这个{a1}图书馆似乎得到了良好的评价和声誉

到目前为止我完成了什么

1. 我已经成功创建了一个maven项目（显然）
2. 编写了receiver类（工作非常完美）——捕获UDP消息并存储稍后发送POST消息时需要存储的内容的类
3. 编写了负责使用库发送POST消息的代码（我不确定它是否有效，因为我无法运行它）：

    // To make post request to send data
  AsyncHttpClient client = Dsl.asyncHttpClient();

  BoundRequestBuilder postRequest = client
          .preparePost("http://localhost:8080/my_custom_url/")
          .addFormParam("id", myid)
          .addFormParam("stream", inData);

  // Asynchronous execution
  postRequest.execute(new AsyncHandler<Object>() {
      public State onStatusReceived(HttpResponseStatus responseStatus) throws Exception {
          System.out.print("\nstatus received");
          return null;
      }

      public State onHeadersReceived(HttpHeaders headers) throws Exception {
          System.out.print("\nheaders received");
          return null;
      }

      public State onBodyPartReceived(HttpResponseBodyPart bodyPart) throws Exception {
          System.out.print("\nbody part received");
          return null;
      }

      public void onThrowable(Throwable t) {

      }

      public Object onCompleted() throws Exception {
          System.out.print("\nexecute completed");
          return null;
      }
  });

  // Close to stop memory leaks after we are done
  try {           client.close();         } catch (IOException e) {           infoBox("Could not close AsyncHttpClient.", "Error");
      System.exit(0);         }
