HttpHostConnectException：連接被拒絕

我一直在嘗試使用具有JSON響應的GET方法來訪問webservice。通過android但拋出連接拒絕異常。我能夠在瀏覽器上打開URL並獲得響應，但獲取響應需要大約30秒的時間。當我運行我的應用程序時，它等待響應並拋出連接拒絕異常。請幫忙。HttpHostConnectException：連接被拒絕

Login.java（其由OnClick方法的）

class Login{ 

login.setOnClickListener(new View.OnClickListener() { 

      public void onClick(View v) { 
       pro.setVisibility(View.VISIBLE); 
       new ExecuteTask().execute(); 
       /* do{ 
        pro.setVisibility(View.VISIBLE); 
       }while (response=resp())*/ 




       /* if(response.contains("name")){ 

        startActivity(new Intent(Login.this,Tab.class)); 
        overridePendingTransition(R.anim.enter, R.anim.exit); 
       } 
       else if(response.contains("errorMessages")){ 
        showPopUp(); 

       } 
       else if(response.contains("<html>")||response.contains("site can't be reached")){ 
        showerrorPopUp(); 
       } 
       else{ 
        showerrorPopUp(); 

       }*/ 

      } 

     });

異步任務 它調用RESP（）方法

public class ExecuteTask extends AsyncTask<String,Integer,String>{ 


    @Override 
    protected String doInBackground(String... params) { 
     System.out.println("into async task"); 
     String res=resp(); 
     System.out.println("into execute task"+ res); 
     return res; 

    } 
    @Override 
    protected void onPostExecute(String result) { 
     pro.setVisibility(View.GONE); 
     //progess_msz.setVisibility(View.GONE); 

    } 
}

RESP（）方法： 這個我thod由Http連接代碼組成 public String resp（）{0} 0 0 0 0 0 0 0 0 0 0 0 0 0 System.out.println（「resp strt」）;

 System.out.println("into resp"); 
     HttpClient httpClient = new DefaultHttpClient(); 
     HttpGet httpGet = new HttpGet(append(URL)); 
     try { 
      HttpEntity httpEntity = httpClient.execute(httpGet).getEntity(); 
      if (httpEntity != null) { 
       InputStream inputStream = httpEntity.getContent(); 
       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream)); 
       final StringBuilder stringBuilder = new StringBuilder(); 
       String cen = null; 

       while ((cen = bufferedReader.readLine()) != null) { 

        /* Intent intent=new Intent(Login.this,MainActivity.class); 
        startActivity(intent);*/ 
        stringBuilder.append(cen + "n"); 
       } 
       inputStream.close(); 

       resp = stringBuilder.toString(); 
       /*text.setText(resp);*/ 
       System.out.println("response" + resp); 

      } 
     } catch (ClientProtocolException e) { 
      Toast.makeText(Login.this, e.toString(), Toast.LENGTH_LONG); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      Toast.makeText(Login.this, e.toString(), Toast.LENGTH_LONG); 
     } 
     System.out.println("resp end"); 
     return resp; 



    }

append（）方法

public String append(String url){ 
     url+=userName.getText().toString()+"/"+ password.getText().toString(); 
     System.out.println("username"+userName.getText().toString()); 

     return url; 
    }
