Отправка файла на PHP

Question

В коде Android Studio я открываю камеру и делаю снимок, который могу сохранить. Однако затем я хочу отправить эту картинку JPG на мой код PHP. У меня есть сортировка для отправки строк на PHP, однако, когда я пытаюсь отправить изображение, это не работает. Из-за этого я закодировал свое изображение в строку base64, чтобы попытаться отправить его таким образом, но он все еще не работает.

Java код:

public class celebs extends AsyncTask<String, String, String> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);

        //Toast.makeText(getBaseContext(),s,Toast.LENGTH_SHORT).show();
    }

    @RequiresApi(api = Build.VERSION_CODES.O)
    @SuppressLint("WrongThread")
    @Override
    protected String doInBackground(String... params) {

        sharedPreferenceConfig = new SharedPreferenceConfig(getApplicationContext());
        Intent intent = getIntent();
        File Image = (File) intent.getSerializableExtra("Image");

        String encode = encodeFileToBase64Binary(Image);

        try {

            String data = URLEncoder.encode("Image", "UTF-8") + "=" +
                    URLEncoder.encode(String.valueOf(Image), "UTF-8");
            //URL url = new URL("http://192.168.43.35:80/App/pythonconnect.php?" + data);
            URL url = new URL("http://10.167.120.26/App/pythonconnect.php?" + encode);
            System.out.println("1");
            URLConnection con = url.openConnection();
            System.out.println("2");
            con.setDoOutput(true);
            System.out.println("3");

            BufferedReader read = new BufferedReader(new InputStreamReader(con.getInputStream()));
            StringBuilder s = new StringBuilder();
            String line = null;
            while ((line = read.readLine()) != null) {
                s.append(line);
            }
            final String result = s.toString();
            System.out.println(result);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}


@RequiresApi(api = Build.VERSION_CODES.O)
private static String encodeFileToBase64Binary(File file){
    String encodedfile = null;
    try {
        FileInputStream fileInputStreamReader = new FileInputStream(file);
        byte[] bytes = new byte[(int)file.length()];
        fileInputStreamReader.read(bytes);
        encodedfile = Base64.getEncoder().encodeToString(bytes);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return encodedfile;
}

Мой php код:

<?php
    if (isset($_POST["Image"])) {
      "include connection.php";
      $image = $_POST["Image"];

      $message = exec("/Applications/XAMPP/xamppfiles/htdocs/App/database.py 2>&1 '$imagestr'");
      echo($message);
    }
?>

Answer 1

Отправка изображения в виде строки, закодированной в base64, не идеальный метод, потому что GET и POST имеют ограничение символов в своем запросе. Это приведет к слишком большой ошибке 413 запроса объекта .

Лучший способ отправки изображения на сервер - это использование составного запроса от Android.
