Problems submitting an image using MultipartRequest

[rdvg...@gmail.com]

Hi,

I am working on a WS made in PHP. I was able to create some routines to receive an image and save them in a folder on the server. All this I have been testing in Postman and it works 100%.

In the WS I do not validate the HTTP method, but I assume it is POST.

From my mobile app I send the file with the MultipartRequest class. I was able to validate by debugging the response code 200, however I can't get the file to be created in the folder.

I have 3 days struggling with this and I don't see the problem. I copy the code to see if you can see the error.

I take this opportunity to ask if it is valid to send additional arguments, since I need to send the name of the database and the company code to create the folder where the image will be saved.

My code:

    public static void actualizaImagenFoto(String rutaImagen, Long visitaId) {

        try {

            MultipartRequest mp = new MultipartRequest();

            mp.setUrl(SERVER_URL + "ws_foto_imagen/ws_foto_imagen.php");

 //           mp.addArgument("token", UsuarioService.getToken());

 //           mp.addArgument("fot_visita_id", visitaId.toString());

            mp.addData("imagen", rutaImagen, "image/jpeg");

            addToQueue(mp);

            System.out.println(Integer.toString(mp.getResponseCode()) + "   " + mp.getResponseErrorMessage());

        } catch (IOException err) {

            Log.e(err);

            ToastBar.showErrorMessage("Error en actualización de la foto: " + err.getMessage());

        }

    }

Hi,

Detect the problem by including the following parameters:

             mp.setFilename ("image", "data.jpeg");

             mp.setPost (true);

However, I would like to know how I can send 2 additional arguments (Database and Company Number).

Thanks

Hi,
using the regular addArgument should work just fine. It will be added to the multipart seamlessly.

Hi,

I asked him about the arguments because I did not get the ws to recognize them

Can't be sure without looking at your entire implementation but here are 2 ideas:

1- make sure to add the file via MultipartRequest.addData( and don't call setPost or setFileName

2- make sure your test call in Postman is using Multipart https://stackoverflow.com/questions/16015548/how-to-send-multipart-form-data-request-using-postman

Hi,

Thank you mr Shai and mr Javier for your reply

I thought it worked, but I was wrong.

I'm going to name everything I've done. As I mentioned in postman it works fine and this is the configuration:

The code in PHP is small and although it is not the topic of this forum I am going to include it (suddenly someone detects a problem):

//Coloca los encabezados 

header('Access-Control-Allow-Origin: *');

header('Access-Control-Allow-Methods: PUT, GET, POST, DELETE');  

header('Content-Type: application/json; text/html; charset=UTF-8; multipart/form-data');

header('Access-Control-Max-Age: 3600');

header('Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With');

// Generar archivo .htaccess si es necesario.

ws_htaccess();

$bd = isset($_GET['bd']) ? $_GET['bd'] : null;

if (isset($_FILES['imagen']['name'])) {

$fileName  =  $_FILES['imagen']['name'];

$tempPath  =  $_FILES['imagen']['tmp_name'];

// Extensiones validas

$valid_extensions = array('jpeg', 'jpg', 'png', 'gif'); 

$ext = strtolower(pathinfo($fileName, PATHINFO_EXTENSION)); // toma la extension de la imagen

if (in_array($ext, $valid_extensions)) { // Valida que la extensión sea valida

$ruta = "../../../file/img/".$bd."/imagen";

if (!file_exists($ruta)) {

mkdir($ruta, 0777, true);

}

move_uploaded_file($tempPath, $ruta."/".$fileName);

}

} else {

return getResponse('error', null, 500, 'Fallo en la creación / actualización de la foto');

}

And finally the code in the mobile app:

public static void actualizaImagenFoto(String imagen, String rutaImagen) {

        try {

            MultipartRequest mp = new MultipartRequest();

            mp.setUrl(SERVER_URL + "ws_foto_imagen/ws_foto_imagen.php");

            mp.addArgument("bd", Preferences.get("bd", "tempus"));

            mp.addData("imagen", rutaImagen, "image/jpeg");

            mp.setFilename("imagen", imagen);

            mp.setPost(true);

            System.out.println(Integer.toString(mp.getResponseCode()) + "   " + mp.getResponseErrorMessage());

        } catch (IOException err) {

            Log.e(err);

            ToastBar.showErrorMessage("Error en actualización de la foto: " + err.getMessage());

        }

    }

With or without the setPost and setFileName methods it's not working for me.

I appreciate your comments because I do not know what to continue doing.

Hi,

Uff, at some point delete the line "addToQueue (mp);". Also note that although in Postman I use the "POST" method it is necessary for the parameters to be detected in PHP with $ _GET ['variable'], however when it is executed from a client it is necessary to use $ _POST ['variable'].

Thanks for the support and sorry for the inconvenience.

Hi,

multipart is a multipart file upload. Which isn't "form-data" it's "x-www-form-urlencode" which is a very different thing.

If you don't need that you shouldn't use multipart and should use a regular connection request. Just submit the file as a byte[].

If an argument is passed as get just pass it manually in the URL by adding it to the string using the ? and & characters.
