Android Studio AsyncHttpClient 发布请求不起作用 REST

Question

我正在 Android Studio 中创建一个应用程序。我正在尝试通过我之前配置的休息服务将 5 个参数发送到数据库。我已经通过浏览器插件和发布请求测试了网页并且工作正常，所以我确定问题出在应用程序本身。我还确保我发送的数据也很好（locationX、locationY、时间、日期、用户名）。有谁知道为什么这不起作用？

public void onClickSendCoordinates(View v)
{
    final EditText textbox3 = (EditText) findViewById(R.id.textbox3);

    String date = DateFormat.getDateInstance().format(new Date());
    String time = DateFormat.getTimeInstance().format(new Date());
    String url = "http://somewebsite.com/index.php";
    String locationX = textbox2.getText().toString();
    String locationY = textbox1.getText().toString();
    String username = "user_1";

    EditText textbox4 = (EditText) findViewById(R.id.textbox4);
    textbox4.setText(username + locationX + locationY + date + time);
    AsyncHttpClient httpClient = new AsyncHttpClient();
    RequestParams params = new RequestParams();

    params.put("username", username);
    params.put("locationX", locationX);
    params.put("locationY", locationY);
    params.put("date", date);
    params.put("time", time);

    httpClient.post(url, params, new TextHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, String res) {
            //called when response HTTP status is "200 OK"
            textbox3.setText("Success");
          //  Toast.makeText(getApplication(),"Sending URL " + url + "with params " + params.toString(), Toast.LENGTH_LONG);
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, String res, Throwable t) {
            textbox3.setText("Failure");
          //  Toast.makeText(getApplication(), "Sending URL " + url + "with params " + params.toString(), Toast.LENGTH_LONG);
            //called when response HTTP status is "4xx" (eg. 401, 403, 404)
        }
    });
}

HttpClient 在 23 中已弃用。请使用 HttpURLConnnection。

// HTTP GET request

public String sendGet(String apiUrl) {
    StringBuilder result = new StringBuilder();
    HttpURLConnection urlConnection = null;
    try {
        URL url = new URL(apiUrl);
        urlConnection = (HttpURLConnection) url.openConnection();
        InputStream in = new BufferedInputStream(urlConnection.getInputStream());
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        String line;
        while ((line = reader.readLine()) != null) {
            result.append(line);
        }

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        urlConnection.disconnect();
    }
    return result.toString();
}

对于 HTTP POST

  // HTTP POST request
public String sendPost(String apiurl, String args) {
    String response = "";
    try {
        URL url= new URL(apiurl);;
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        DataOutputStream printout;
        DataInputStream input;
        conn.setDoInput(true);
        conn.setDoOutput(true);
        conn.setUseCaches(false);
        conn.setRequestProperty("Content-Type", "application/json");
        conn.connect();
        printout = new DataOutputStream(conn.getOutputStream());
        byte[] data=args.getBytes("UTF-8");
        printout.write(data);
        printout.flush();
        printout.close();

        int responseCode =conn.getResponseCode();

        if (responseCode == HttpsURLConnection.HTTP_OK) {
            String line;
            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            while ((line = br.readLine()) != null) {
                response += line;
            }
        } else {
            response = "";

        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return response;
}
