HttpurlConnection Post请求正文php服务器？

Question

我有一个文件的服务器。 php好，我想送岗位request服务器与我的应用我想这样做，但我总是得到“”当我试穿邮递员我的服务器我得到

{“结果”：“jfYRsbW17HA3bHtaJdDm” ， “的errorMessage”：“错误”}

我想我的应用程序看到这些时，我在这里发送POST请求我的代码：（为什么我得到空）

public class HttpParoonakRequest { 


public static String HttpParoonakRequestGetUrl(){ 


    URL url ; 
     HttpURLConnection client = null; 
    try { 

     url = new URL("myphp"); 

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

     client.setRequestProperty("method","get_random_wallpaper"); 



     client.setDoInput(true); 
     client.setDoOutput(true); 
     client.connect(); 
     DataOutputStream wr = new DataOutputStream (
       client.getOutputStream()); 

     wr.flush(); 
     wr.close(); 

     //Get Response 
     InputStream is = client.getInputStream(); 
     BufferedReader rd = new BufferedReader(new InputStreamReader(is)); 
     String line; 
     StringBuffer response = new StringBuffer(); 

     while((line = rd.readLine()) != null) { 
      response.append(line); 
      response.append('\n'); 

     } 
     Log.d("hey",response.toString()); 

     rd.close(); 

     return response.toString(); 


    } catch (Exception e) { 

     e.printStackTrace(); 
     return e.getMessage(); 
    } 
    finally { 
     if(client != null) // Make sure the connection is not null. 
      client.disconnect(); 
    } 



} 

，并调用它这种方式在另一个acti VITY：

thread = new Thread(new Runnable() { 


      @Override 
      public void run() { 
       try { 
        String abcd = HttpParoonakRequest.HttpParoonakRequestGetUrl(); 
        System.out.println("Message1 "+ abcd); 

       } catch (Exception e) { 

        e.printStackTrace(); 
        e.getMessage(); 
       } 

      } 
     }); 
     thread.start();

你路过走错了路参数：你应该client.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");取代client.setRequestProperty("method","get_random_wallpaper")，并通过wr流这样的传递请求体的参数：

   ...  

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

       client.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 

       client.setDoInput(true); 
       client.setDoOutput(true); 
       client.connect(); 
       DataOutputStream wr = new DataOutputStream(
         client.getOutputStream()); 

       wr.write("method=get_random_wallpaper".getBytes()); 

       wr.flush(); 
       wr.close(); 
       ...
