Android - HTTP 게시 요청

Question

내 Android 장치에서 내 서버로 일부 지리 정보를 보내려는 POST 요청을 호출하고 싶습니다.

내 서버는 PHP를 사용하며 PHP 스크립트를 사용하여 들어오는 모든 게시물 요청을 데이터베이스에 저장하고 싶습니다. 내 PHP 스크립트는 곱슬 곱슬 해봤을 때 잘 작동하지만 안드로이드 장치에서 일부 정보를 보내려고 할 때 네트워크 오류가 발생합니다. 여기

내 오류가 기록됩니다

이 예외는 응용 프로그램이 주 스레드에서 네트워킹 작업을 수행하려고 할 때 발생합니다. AsyncTask에서 코드를 실행하십시오.

public class HttpPost extends AsyncTask<String, String, String> { 


    protected String doInBackground(String... args) { 
     URL url = null; 
     HttpURLConnection httpURLConnection = null; 
     OutputStream outputStream = null; 

     try{ 
      url = new URL("http://example.local"); 
      httpURLConnection = (HttpURLConnection) url.openConnection(); 

      Timestamp timestamp = new Timestamp(System.currentTimeMillis()); 

      /*httpURLConnection.setRequestMethod("POST"); 
      httpURLConnection.setRequestProperty("d", this.getDeviceId()); 
      httpURLConnection.setRequestProperty("lat", Double.toString(location.getLatitude())); 
      httpURLConnection.setRequestProperty("lon", Double.toString(location.getLongitude())); 
      httpURLConnection.setRequestProperty("t", timestamp.toString()); 
      httpURLConnection.setDoOutput(true);*/ 

      outputStream = new BufferedOutputStream(httpURLConnection.getOutputStream()); 

      BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8")); 

      writer.write(Double.toString(location.getLongitude())); 
      writer.flush(); 
      writer.close(); 
      outputStream.close(); 
      httpURLConnection.disconnect(); 

      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
    } 

    protected void onPostExecute(String result) { 
     //What you want to do with the result 
     //Call a callback function for instance 
     //You can also delete this method if you dont expect a result 
    } 
}
