آپلود فایل به سرور [حل شد]

دوست عزیز من متاسفانه امکان تست کد شما رو ندارم. ولی چند وقت پیش نیاز بوددر پروژه ای یک عکس به همراه سایر پارامترها به سرور ارسال بشه. روش زیر کاری بود که من انجام دادم.

 imgPicture.buildDrawingCache();
            Bitmap bitmap = imgPicture.getDrawingCache();
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); //compress to which format you want.
            byte[] byte_arr = stream.toByteArray();
            String image_str = com.navahi.helper.Base64.encodeBytes(byte_arr);

            params.add(new BasicNameValuePair("picture", image_str));

این هم تابعی که تو کد استفاده شده.

 /**
     * Encodes a byte array into Base64 notation.
     * Does not GZip-compress data.
     * 
     * @param source The data to convert
     * @return The data in Base64-encoded form
     * @throws NullPointerException if source array is null
     * @since 1.4
     */
    public static String encodeBytes(byte[] source) {
        // Since we're not going to have the GZIP encoding turned on,
        // we're not going to have an java.io.IOException thrown, so
        // we should not force the user to have to catch it.
        String encoded = null;
        try {
            encoded = encodeBytes(source, 0, source.length, NO_OPTIONS);
        }
        catch (java.io.IOException ex) {
            assert false : ex.getMessage();
        } // end catch
        assert encoded != null;
        return encoded;
    } // end encodeBytes

البته کد سمت سرورم به زبان asp.net هستش. ولی کد رو براتون میزارم تا دقیقا بفهمید اون ور داره چه اتفاقی می افته . دقت کنید ابتدا در دورودی تابع با عکسی که آپلود شده به شکل یک string رفتار میشه و بعد تبدیلش می کنم.

 if (!string.IsNullOrWhiteSpace(picture))
            {
                adsPicture = Helper.ConvertBase64ToImage(picture);
            }

این هم تابعی که سمت سرور داره تبدیل میکنه.

 public static Image ConvertBase64ToImage(string base64String)
    {
        // Convert Base64 String to byte[]
        byte[] imageBytes = Convert.FromBase64String(base64String);
        using (var ms = new MemoryStream(imageBytes, 0,
                                         imageBytes.Length))
        {
            // Convert byte[] to Image
            ms.Write(imageBytes, 0, imageBytes.Length);
            Image image = Image.FromStream(ms, true);
            return image;
        }
    }

این سورس کاملا تست شده و جواب میده :

با سلام. من کد آقای alu رو دانلود کردم و استفاده کردم. اما مشکلم در مورد آپلود حل نشد.

آدرس عکسهام به طور مثال اینه:

String filePath = "/storage/sdcard1/DCIM/100ANDRO/DSC_0057.JPG"

فرمت آدرسم درسته یا اشتباه؟

و به این صورت به متد upload میفرستم:

  UploadFile.upload(filePath);

برنامه توی خط زیر متوقف میشه و جلوتر نمیره.

outputStream = new DataOutputStream(connection.getOutputStream());

یا فرمت آدرس عکسهام مشکل داره یا کد php یا آدرس سرور.

این:

 String urlServer = "http://192.168.2.186/test-upload/upload.php";

یا این:

 <?php
if(isset($_FILES['file'])){
	$target_path = "/images/";                         اینجا دقیقا چی باید بذارم؟  
	$target_path = $target_path . basename($_FILES['file']['name']);
	if (move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {
		die("1");
	} else {
		die("2");
	}
}
?>

ممنون میشم کمک کنید از صبح تا حالا دارم تلاش میکنم.

خیلی تو اینترنت گشتم ولی بجوابم نرسیدم میتونین راهنمایی کنین؟ میخوام همزمان با اون فایل که آپلود میشه ، 2 تا مقدار دیگه هم بفرستم ، مثلا ، عنوا ن فایل و ... ! ، با متد پست رو که بلدم ، میخوام با همین URL Connection داده بفرستم !

بالاخره درست کردم.

conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", selectedPath);

dos = new DataOutputStream(conn.getOutputStream());

dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"title\""+ lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes("ok");
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);

dos.writeBytes("Content-Disposition: form-data; name=\"description\""+ lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes("Description");
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);

dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
        + selectedPath + "\"" + lineEnd);

dos.writeBytes(lineEnd);

Log.e("TAG","Headers are written");

// create a buffer of maximum size
bytesAvailable = fileInputStream.available();

maxBufferSize = 1024;
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];

// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);

while (bytesRead > 0)
{
    dos.write(buffer, 0, bufferSize);
    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable,maxBufferSize);
    bytesRead = fileInputStream.read(buffer, 0,bufferSize);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();

Log.i("uploadFile", "HTTP Response is : "
        + serverResponseMessage + ": " + serverResponseCode);

if(serverResponseCode == 200){

}

//close the streams //
fileInputStream.close();
dos.flush();
dos.close();
