Question

我最近调整了我的android studio app，以1秒的间隔上传LatLon数据。在此之前，我使用按钮定期上传数据，这种方法工作正常，我可以在MySQL中看到数据。

我仍在使用相同的PHP脚本在MYSQL数据库中发布数据。我的logcat显示它尝试发送数据，但gry.php文件不存在。

Android Studio功能：

public void uploadInfo(View view){

        BackgroundOp backgroundOp = new BackgroundOp();
        backgroundOp.execute(latString, lonString);
    }



    class BackgroundOp extends AsyncTask<String, Void, String> {

        String myUrl;

        @Override
        protected void onPreExecute() {
            myUrl = "[web address]/qry.php";
        }

        @Override
        protected String doInBackground(String... data) {
            String latString, lonString;
            latString = data [0];
            lonString = data [1];

            try {
                URL url = new URL(myUrl);
                HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();
                httpURLConnection.setRequestMethod("POST");
                httpURLConnection.setDoOutput(true);
                OutputStream outputStream = httpURLConnection.getOutputStream();
                BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
                String myDataStream = URLEncoder.encode("Latitude", "UTF-8") + "=" + URLEncoder.encode(latString, "UTF-8") + "&" +
                        URLEncoder.encode("Longitude", "UTF-8") + "=" + URLEncoder.encode(lonString, "UTF-8");
                bufferedWriter.write(myDataStream);
                bufferedWriter.flush();
                bufferedWriter.close();
                outputStream.close();
                InputStream inputStream = httpURLConnection.getInputStream();
                inputStream.close();
                httpURLConnection.disconnect();
                return "Upload Successful";

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

            return null;
        }

        @Override
        protected void onProgressUpdate(Void... values) {
            super.onProgressUpdate(values);
        }

        @Override
        protected void onPostExecute(String result) {
            Toast.makeText(getApplicationContext(), result, Toast.LENGTH_LONG).show();
        }
    }

qry.php：

<?php

    require "params.php";

    $Latitude = $_POST["Latitude"];
    $Longitude = $_POST["Longitude"];
    $Time = $_POST["Time"];

    $sql_query = "insert into loc_info values('$Latitude', '$Longitude', '$Time');";

    if (mysqli_query($connect, $sql_query)){
        echo "<br>Data writing successful";
    } else {
        echo "<br>Data writing failed".mysqli_error($connect);
    }

?>

logcat的：
