Java的HttpURLConnection类不发布数据

Question

世界各地的朋友，

也许我问同一个问题都结束了，但我已经寻找了几个小时，但还没有找到答案，

我想发布对象到服务器，它实际上能够联系服务器，但没有向服务器发送数据，请赐教，

这里是我的Java代码

protected String doInBackground(String... params) { 
     URL url = null; 
     try { 
      String location = URLEncoder.encode(params[0],"UTF-8"); 
      url = new URL("SERVER ADDRESS"); 
      con = (HttpsURLConnection) url.openConnection(); 
      con.setRequestMethod("POST"); 
      con.setRequestProperty("Content-Type","application/json"); 
      con.setRequestProperty("Accept", "*/*"); 
      con.setDoOutput(true); 
      con.setDoInput(true); 
      OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream()); 
      JSONObject jsonParam = new JSONObject(); 
      jsonParam.put("ID", "25"); 
      jsonParam.put("description", "Real"); 
      jsonParam.put("enable", "true"); 
      out.write(jsonParam.toString()); 
      out.flush(); 
      Log.i("aware", jsonParam.toString()); 
      InputStream stream = con.getInputStream(); 
      reader = new BufferedReader(new InputStreamReader(stream)); 

      StringBuffer buffer = new StringBuffer(); 

      String line = ""; 

      while((line=reader.readLine()) != null) { 
       buffer.append(line); 
      } 

      String json = buffer.toString(); 
      Log.i("json", json); 
      // handle issues 
      int statusCode = con.getResponseCode(); 
      Log.e("Response", "The response is: " + statusCode); 
      out.close(); 
      reader.close(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

这是PHP代码

header('Content-Type: application/json'); 
$response = array(); 

if(!empty($_REQUEST)) { 
    $myPost = json_encode($_REQUEST); 
    echo $myPost; 
    $myfile = fopen("request.txt", "w") or die("Unable to open file!"); 
    fwrite($myfile, $myPost); 
    fclose($myfile); 
    $response['statusget'] = "good"; 
} 

if(!empty($_GET)) { 
    $myPost = json_encode($_GET); 
    echo $myPost; 
    $myfile = fopen("get.txt", "w") or die("Unable to open file!"); 
    fwrite($myfile, $myPost); 
    fclose($myfile); 
    $response['statusget'] = "good"; 
} 
if(!empty($_POST)) { 
    $myPost = json_encode($_POST); 
    echo $myPost; 
    $myfile = fopen("post.txt", "w") or die("Unable to open file!"); 
    fwrite($myfile, $myPost); 
    fclose($myfile); 
    $response['statuspost'] = "good"; 
} 
if(empty($jsonString) && empty($_GET) && empty($_POST)) { 
    $response['status'] = "nothing"; 
} 

echo json_encode($response); 

日志是这样

Answer 1

回答！只需添加字符串writebytes out.writeBytes("data="+jsonParam.toString());
