GET请求

private EditText input;
  private TextView info;

  private final int UPDATE_UI = 1;

  @SuppressLint("HandlerLeak") private Handler mHandler = new Handler() {
    @Override public void handleMessage(Message msg) {
      switch (msg.what) {
        case UPDATE_UI:
          info.setText(msg.obj.toString());
          break;
      }
    }
  };

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    input = findViewById(R.id.input);
    info = findViewById(R.id.info);

    findViewById(R.id.query).setOnClickListener(new View.OnClickListener() {
      @Override public void onClick(View v) {
        new Thread(
            new Runnable() {
              @Override public void run() {
                //在build.gradle中声明使用
                //添加依赖
                //getRequestData(input.getText().toString());
                postRequestData(input.getText().toString());
              }
            }
        ).start();
      }
    });
  }

  private String url = "http://tcc.taobao.com/cc/json/mobile_tel_segment.htm";

  private void getRequestData(String phoneNum) {
    //1 创建 HttpClient
    HttpClient client = HttpClients.createDefault();

    //HttpUriRequest
    HttpGet get = new HttpGet(url + "?tel=" + phoneNum);

    try {
      //shift f6 重构
      //执行请求
      HttpResponse response = client.execute(get);

      //获取结果
      int statusCode = response.getStatusLine().getStatusCode();
      if (statusCode == 200) {
        String result = EntityUtils.toString(response.getEntity());
        mHandler.sendMessage(mHandler.obtainMessage(UPDATE_UI, result));
      }
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

POST请求

 private void postRequestData(String phoneNum) {
    try {
      //创建HttpClient
      HttpClient client = HttpClients.createDefault();

      //post请求
      HttpPost post = new HttpPost(url);

      // 构建请求参数
      List<NameValuePair> params = new ArrayList<>();
      params.add(new BasicNameValuePair("tel", phoneNum));

      //请求体
      post.setEntity(new UrlEncodedFormEntity(params));

      //执行请求
      HttpResponse response = client.execute(post);

      //获取结果
      int statusCode = response.getStatusLine().getStatusCode();
      if (statusCode == 200) {
        String result = EntityUtils.toString(response.getEntity());
        mHandler.sendMessage(mHandler.obtainMessage(UPDATE_UI, result));
      }
    } catch (UnsupportedEncodingException e) {
      e.printStackTrace();
    } catch (ClientProtocolException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
