Android：HttpGet不張貼到數據庫

Question

我只是試圖發送數據到數據庫作爲概念證明。我目前有一個ASP頁面，將爲我發送數據。我有一個非常基本的Android應用程序將信息發佈到數據庫，但沒有任何數據發佈在那裏。我沒有收到任何錯誤或強制關閉，url是使用該特定ASP文件發送到數據庫的正確url和格式。

這裏是我的代碼

HttpClient client = new DefaultHttpClient(); 

      //set url 
      String url = "**removed for security reasons**"; 
      url += "var1=" + editVar1.getText().toString() + "&var2=" + editVar2.getText().toString() + "&var3=" + editVar3.getText().toString(); 

      //display url in toast 
      Toast toast = Toast.makeText(getApplicationContext(), url, Toast.LENGTH_LONG); 
      toast.show(); 

      //prepare connection 
      HttpGet request = new HttpGet(url); 

      //send HttpGet 
      try 
      { 
       client.execute(request); 
      } 
      catch (Exception e){}

首先只是爲了通知你，網絡操作應該在後臺（作爲的AsyncTask或intentService）執行。 其次，你不應該使用GET在數據庫中寫東西。 您應該使用POST，並沒有得到：

 HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(url); 

     try { 
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3); 
      nameValuePairs.add(new BasicNameValuePair("var1", editVar1.getText().toString())); 
      nameValuePairs.add(new BasicNameValuePair("var2",editVar2.getText().toString())); 
      nameValuePairs.add(new BasicNameValuePair("var3",editVar3.getText().toString())); 
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

      HttpResponse response = httpclient.execute(httppost);
