如何實現移動充值API？

Question

如何在android studio中實現移動充值API。我正在開發用於移動充值Android應用我有把鑰匙，但我需要知道如何實現這些API，請幫助

Answer 1

首先你需要的API 它可能看起來像這樣

www.yourmobilecarrier.com/api/recharge 

此Web服務應接受POST請求。這裏充值業務必須有兩件事情， 1）充值針數 2）電話號碼 這一點，你需要通過Android的

地方剛下課的最後一個大括號之前發佈的數據下面的代碼後

class Recharge extends AsyncTask<String, Void, String> { 

     HttpURLConnection urlConnection; 
     String urlString; 
     @Override 
     protected String doInBackground(String... strings) { 
      urlString = "http://recharge.com/recharge"; 
      try { 
       URL url = new URL(urlString); 

       urlConnection = (HttpURLConnection) url.openConnection(); 
       urlConnection.setRequestMethod("POST"); 

       urlConnection.setDoOutput(true); 

       String postingData = URLEncoder.encode("pin", "UTF-8") + "=" + URLEncoder.encode("123456789", "UTF-8") + 
         "&" + URLEncoder.encode("mobile-no", "UTF-8") + "=" + URLEncoder.encode("9845621456", "UTF-8"); 
       BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(urlConnection.getOutputStream())); 
       bufferedWriter.write(postingData); 
       bufferedWriter.flush(); 
       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream())); 
       String line; 
       String result = null; 
       while ((line = bufferedReader.readLine()) != null) { 
        result = result + line; 
       } 
      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
      return null; 
     } 


    } 

爲了執行這個服務使用

Recharge recharge= new Recharge(MainActivity.this); //put you current class name where you are placing the code 
recharge.execute();
