Java HttpUrlConnection 未发布数据

Question

世界各地的朋友，

也许我问的都是同一个问题，但我已经搜索了几个小时但仍未找到答案，

我正在尝试post一个对象到服务器，它居然能联系到服务器，但是没有数据发送到服务器，请赐教，

这是我的 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);

日志是这样的

已找到答案！只需将字符串添加到 writebytes out.writeBytes("data="+jsonParam.toString());
