没有从服务器得到任何响应

Question

我试图将值插入MySql服务器，但没有任何反应。

这是我的代码..

 @Override
    protected String doInBackground(String... strings) {
        String reg_url="http://192.168.43.198:80/android_connect/insert_to_profile_table.php";
        String f_name = first_name.getText().toString();
        String l_name = last_name.getText().toString();
        String address = p_address.getText().toString();
        String phne_hme = phne_home.getText().toString();
        String phne_ofice = phne_office.getText().toString();
        String State = state_spinner.getSelectedItem().toString();
        String district = district_spinner.getSelectedItem().toString();
                   try {
                    URL url=new URL(reg_url);
                    HttpURLConnection httpURLConnection=(HttpURLConnection) url.openConnection();
                    httpURLConnection.setRequestMethod("POST");
                    httpURLConnection.setDoOutput(true);
                    OutputStream os=httpURLConnection.getOutputStream();

                    BufferedWriter bufferedWriter=new BufferedWriter(new OutputStreamWriter(os,"UTF-8"));

                    String data= URLEncoder.encode("first_name","UTF-8")+"="+URLEncoder.encode(f_name,"UTF-8")+"&"+

                    //System.out.print(data.toString());
                    bufferedWriter.write(data);
                    bufferedWriter.flush();
                    bufferedWriter.close();
                    os.close();
                    InputStream IS=httpURLConnection.getInputStream();
                    IS.close();
                    return "Registration Successful";


                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {

    sendPostReqAsyncTask.execute(fname,lname,address,phne_hme,phn_ofice,State,district);
}

Don't forget to add Org.Apache.Http.Legacy this dependency in your gradle file.
