Carga de PHP desde iOS usando Alamofire

swift file-upload

Question

Estoy intentando subir 3 imágenes al servidor desde iOS a mi servicio de PHP. Por alguna razón, la carpeta permanece vacía después de la publicación, pero el resto de los datos se procesan y se mantienen en mysql.

Mi código de iOS:

Alamofire.upload(.POST, urlString, multipartFormData: {
            multipartFormData in

            if (firstPhoto != nil) {
                if  let firstImageData = UIImageJPEGRepresentation(firstImage!, 0.6) {
                    print("uploading image");
                    multipartFormData.appendBodyPart(data: firstImageData, name: "firstImage", fileName: "firstImage.png", mimeType: "image/png")
                }
            }

            if (secondPhoto != nil) {
                if  let secondImageData = UIImageJPEGRepresentation(secondImage!, 0.6) {
                    print("uploading image");
                    multipartFormData.appendBodyPart(data: secondImageData, name: "secondImage", fileName: "secondImage.png", mimeType: "image/png")
                }
            }

            if (thirdPhoto != nil) {
                if  let thirdImageData = UIImageJPEGRepresentation(thirdImage!, 0.6) {
                    print("uploading image");
                    multipartFormData.appendBodyPart(data: thirdImageData, name: "thirdImage", fileName: "thirdImage.png", mimeType: "image/png")
                }
            }


            if  let imageData = UIImageJPEGRepresentation(firstImage!, 0.6) {
                print("uploading image");
                multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
            }

            if  let imageData = UIImageJPEGRepresentation(firstImage!, 0.6) {
                print("uploading image");
                multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
            }


            for (key, value) in parameters {
                multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
            }

            }, encodingCompletion: {
                encodingResult in

                switch encodingResult {
                case .Success(let upload, _, _):
                    print("Запрос отправлен")
                    upload.responseJSON { response in
                        print(response.request)  // original URL request
                        print(response.response) // URL response
                        print(response.data)     // server data
                        print(response.result)   // result of response serialization

                        if let JSON = response.result.value {
                            print("JSON: /(JSON)")
                        }
                        completion(response.result.value)
                    }

                case .Failure(let encodingError):
                    print(encodingError)
                    completion(nil)
                }
        })

}

En mi PHP no estoy seguro de si me falta algo aquí:

 <?php

require_once ''Functions/common_functions.php'';
require_once ''Functions/engine.php'';
require_once ''Functions/json.php'';
require_once ''Functions/check_token.php'';

            $_REQUEST[$mysqli->real_escape_string($k)] = $mysqli->real_escape_string($v);
        } else {
            die(errorJSON("Empty parameter", "666"));
        }
    }

    $userID = checkAccessToken($_REQUEST[''access_token''], $mysqli);

    if ($userID == 0) {
        die(errorJSON("Incorrect access token", "666"));
    }

    $mysqli->query(''INSERT INTO Book (title, authorID, detail, price, categoryID, conditionText) VALUES ("''.$_REQUEST[''title''].''", "''.$userID.''", "''.$_REQUEST[''detail''].''", "''.$_REQUEST[''price''].''", "''.$_REQUEST[''categoryID''].''", "''.$_REQUEST[''condition''].''")'');

    if ($insertID > 0) {
        savePhotos($mysqli, $insertID);
        $message = book($insertID, $userID, $mysqli);
        die(successJSON($message));
    } else {
        die(errorJSON("Failed insert book in database", "666"));
    }
} else {
    die(errorJSON("Incorrect count of parameter" .  count($REQUEST) . count($_POST), "666"));
}

function savePhotos($mysqli, $bookID) {

    }
    try {

        $file = $_FILES[''userfile''][''photo1''];

Answer 1

El problema está en la función savePhotos de la fuente PHP. También un código adicional escrito en el código de iOS. He eliminado el código adicional. Trata una vez.

Aquí está el código de iOS actualizado

Alamofire.upload(.POST, urlString, multipartFormData: {
        multipartFormData in

        if (firstPhoto != nil) {
            if  let firstImageData = UIImagePNGRepresentation(firstImage!, 0.6) {
                print("uploading image");
                multipartFormData.appendBodyPart(data: firstImageData, name: "firstImage", fileName: "firstImage.png", mimeType: "image/png")
            }
        }

        if (secondPhoto != nil) {
            if  let secondImageData = UIImagePNGRepresentation(secondImage!, 0.6) {
                print("uploading image");
                multipartFormData.appendBodyPart(data: secondImageData, name: "secondImage", fileName: "secondImage.png", mimeType: "image/png")
            }
        }

        if (thirdPhoto != nil) {
            if  let thirdImageData = UIImagePNGRepresentation(thirdImage!, 0.6) {
                print("uploading image");
                multipartFormData.appendBodyPart(data: thirdImageData, name: "thirdImage", fileName: "thirdImage.png", mimeType: "image/png")
            }
        }

        for (key, value) in parameters {
            multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
        }

        }, encodingCompletion: {
            encodingResult in

            switch encodingResult {
            case .Success(let upload, _, _):
                print("Запрос отправлен")
                upload.responseJSON { response in
                    print(response.request)  // original URL request
                    print(response.response) // URL response
                    print(response.data)     // server data
                    print(response.result)   // result of response serialization

                    if let JSON = response.result.value {
                        print("JSON: /(JSON)")
                    }
                    completion(response.result.value)
                }

            case .Failure(let encodingError):
                print(encodingError)
                completion(nil)
            }
    })

}

Y aquí está el código PHP

function savePhotos($mysqli, $bookID) {
    $basePath = ''/home/thebakpa/resources/book_photos/''
    if(!is_dir($basePath)) {
        mkdir($basePath, 0777, true);
    }
    try {
        $file1 = $_FILES[''firstImage''];

        if (is_uploaded_file($file1[''tmp_name''])) {
            $photoPath = $basePath.''photo1-''.$bookID.''.jpg'';

            if (move_uploaded_file($file1[''tmp_name''], $photoPath)) {
                $mysqli->query(''UPDATE Book SET photo1=''.$photoPath.'' WHERE bookID=''.$bookID.'''');
            }
        }

        $file2 = $_FILES[''secondImage''];

        if (is_uploaded_file($file2[''tmp_name''])) {
            $photoPath = $basePath.''photo2-''.$bookID.''.jpg'';

            if (move_uploaded_file($file2[''tmp_name''], $photoPath)) {
                $mysqli->query(''UPDATE Book SET photo2=''.$photoPath.'' WHERE bookID=''.$bookID.'''');
            }
        }

        $file3 = $_FILES[''thirdImage''];

        if (is_uploaded_file($file3[''tmp_name''])) {
            $photoPath = $basePath.''photo3-''.$bookID.''.jpg'';

            if (move_uploaded_file($file3[''tmp_name''], $photoPath)) {
                $mysqli->query(''UPDATE Book SET photo3=''.$photoPath.'' WHERE bookID=''.$bookID.'''');
            }
        }
    } catch(Exception $ex){
        echo "ERROR:".$ex->GetMessage()."/n";
        exit(1);
    }
}

Answer 2

Los nombres no coinciden [''userfile''][''photo1''] en tu php. Pero en el lado de iOS, userfile y photo1 nunca se usan. Intenta usar $_FILES[''firstImage'']

Answer 3

intente esto si envía la imagen en formato json (repita el mismo código para otras imágenes mediante el ajuste del nombre de la imagen)

<?php       

            $image          = $file;
            $directorypath1 = $uploaddir;
            $img            = str_replace(''data:image/PNG;base64,'', '''', $image);
            $img            = str_replace('' '', ''+'', $img);
            $data           = base64_decode($img);
            $name           = rand() . ''_'' . time() . ".jpg";
            $img_path       = $directorypath1 . $name;
            file_put_contents($img_path, $data);

?>
