意外的状态行：在HttpURLConnection上使用getInputStream（）时的Y������

Question

我正在尝试使用HTTP请求连接到mysql数据库。我创建了一个扩展AsyncTask广告的类，负责发出http post请求和检索数据。这是我的代码：

public class AttemptLogin extends AsyncTask {

        String mUserName;
        String mPassword;

        String un = "admin01";
        String pass = "admin01";
        Connection con;
        Context context;

        AlertDialog dialog ;

        public AttemptLogin(Context context, String mUserName, String Password) {
            this.context   = context;
            this.mUserName = mUserName;
            this.mPassword = Password;
        }

        @Override
        protected void onPreExecute(){
            dialog = new AlertDialog.Builder(context).create();
            dialog.setTitle("Login Status");
        }

        protected  void onPostExecute(String s){
            dialog.setMessage(s);
            dialog.show();
        }

        @Override
        protected Object doInBackground(Object[] objects) {

            try{

                Log.d(tag, "Debut do in background");
                String constr = "http://000.000.0.00:3306/login.php";
                URL url = new URL(constr);
                HttpURLConnection http = (HttpURLConnection)url.openConnection();
                http.setDoInput(true);
                http.setDoOutput(true);
                http.setUseCaches(false);
                http.setRequestMethod("POST");
                http.setRequestProperty("Connection", "close");

                OutputStream ops = http.getOutputStream();
                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(ops,"UTF-8"));

                String data = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode(mUserName, "UTF-8") + " & " +
                              URLEncoder.encode("password", "UTF-8") + "=" + URLEncoder.encode(mPassword, "UTF-8");

                writer.write(data);
                writer.flush();
                writer.close();
                ops.close();

                String result = "";
                String line = "";

                InputStream ips = http.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(ips,"ISO-8859-1"));

                while ((line = reader.readLine()) != null){
                    result += line;
                }

                Log.d(tag, "Result = " + result);

                reader.close();
                ips.close();
                http.disconnect();

                onPostExecute(result);

                return result;

            }
            catch (Exception e) {
                Log.w("Error connection","" + e.getMessage());
                e.printStackTrace();
            }

            return null;

        }
    }

当然，我放置的IP只是为了隐藏我的真实IP。无论如何，getInputStream（）的行返回以下错误：意外的状态行：Y������

我已经尝试了很多事情，包括将“连接”属性设置为“关闭”，但它没有成功。

任何帮助都会受到赞赏，因为我已经被困了一段时间了。谢谢！

您似乎正在尝试向运行MySQL特定协议的端口发出HTTP请求。请求发生，但响应不是HTTP响应，因此是异常。
