图像未从Android上传到服务器

Question

我正在尝试将Android相机捕获的图像上传到服务器，但图片未保存。

机器人：

ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte[] array = stream.toByteArray();
            encoded_string =android.util.Base64.encodeToString(array, android.util.Base64.NO_WRAP);

            String phpUrl = "http://192.168.43.104:80/dogCountingApp/newDog.php";
            URL url = new URL(phpUrl);
            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 data = URLEncoder.encode("encoded_string","UTF-8") + "=" + URLEncoder.encode(encoded_string,"UTF-8")+"&"+
                    URLEncoder.encode("image_name","UTF-8")+"="+URLEncoder.encode(image_name,"UTF-8");
            bufferedwriter.write(data);
            bufferedwriter.flush();
            bufferedwriter.close();
            outputstream.close();

腓

<?php
header('content-type : bitmap; charset = utf-8');

if(isset($_POST["encoded_string"])){

$encoded_string = $_POST["encoded_string"];
$image_name = $_POST["image_name"];

$decoded_string = base64_decode($encoded_string);

$path = 'images/'.$image_name;

$file = fopen($path, 'wb');

fwrite($file, $decoded_string);
fclose($file);

}
?>

非常感谢任何帮助。
