J'essaie de télécharger un fichier en utilisant Alamofire. Le téléchargement fonctionne bien lorsque vous utilisez un fichier ( NSUrl), cependant, je n'arrive pas à comprendre comment utiliser l' NSDataoption?

Voici ce que j'ai comme test:

 var url:NSURL = NSURL.URLWithString("http://localhost:8080/bike.jpeg")

 var err: NSError?
 var imageData :NSData = NSData.dataWithContentsOfURL(url,options: NSDataReadingOptions.DataReadingMappedIfSafe, error: &err)

 Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload/test.png", imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseJSON { (request, response, JSON, error) in
            println(request)
            println(response)
           println(JSON)
 }

Je reçois un code de statut 415?

En outre, comment puis-je envoyer des paramètres supplémentaires lors du téléchargement?

Merci

Je n'ai pas défini le type de contenu correct:

var manager = Manager.sharedInstance
manager.session.configuration.HTTPAdditionalHeaders = ["Content-Type": "application/octet-stream"]


let imageData: NSMutableData = NSMutableData.dataWithData(UIImageJPEGRepresentation(imageTest.image, 30));

Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload?attachmentName=file.jpg",  imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseString { (request, response, JSON, error) in
            println(request)
            println(response)
            println(JSON)
}

Je ne comprends toujours pas comment envoyer des paramètres supplémentaires avec le téléchargement.

Voici une fonction simple qui nécessite l'URL de téléchargement cible, les paramètres et imageData et renvoie l'URLRequestConvertible et NSData dont Alamofire.upload a besoin pour télécharger une image avec des paramètres.

// this function creates the required URLRequestConvertible and NSData we need to use Alamofire.upload
func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    let boundaryConstant = "myRandomBoundary12345";
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")



    // create upload data to send
    let uploadData = NSMutableData()

    // add image
    uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData(imageData)

    // add parameters
    for (key, value) in parameters {
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}    

Voici un exemple de son utilisation (voir CRÉER ET ENVOYER UNE DEMANDE):

// init paramters Dictionary
var parameters = [
    "task": "task",
    "variable1": "var"
]

// add addtionial parameters
parameters["userId"] = "27"
parameters["body"] = "This is the body text."

// example image data
let image = UIImage(named: "177143.jpg")
let imageData = UIImagePNGRepresentation(image)



// CREATE AND SEND REQUEST ----------

let urlRequest = urlRequestWithComponents("http://example.com/uploadText/", parameters: parameters, imageData: imageData)

Alamofire.upload(urlRequest.0, urlRequest.1)
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println("\(totalBytesWritten) / \(totalBytesExpectedToWrite)")
    }
    .responseJSON { (request, response, JSON, error) in
        println("REQUEST \(request)")
        println("RESPONSE \(response)")
        println("JSON \(JSON)")
        println("ERROR \(error)")
}    

Et si vous avez besoin du fichier php pour l'url cible (avec un dossier 'uploads' dans le même répertoire):

// get picture variables
$file       = $_FILES['file']['tmp_name'];
$fileName   = $_FILES['file']['name'];
$fileType   = $_FILES['file']['type'];

// check extension
$allowedExts = array("jpg", "jpeg", "png");
$rootName = reset(explode(".", $fileName));
$extension = end(explode(".", $fileName));

// create new file name
$time = time();
$newName = $rootName.$time.'.'.$extension;

// temporarily save file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/".$newName );
if ($moved) $path = "uploads/".$newName;

$body = $_POST['body'];
$userId = $_POST['userId'];


$time = time();
if ($moved) {
    $fullUrl = "http://antiblank.com/testPhotoUpload/".$path;
    $arrayToSend = array('status'=>'success','time'=>$time,'body'=>$body,'userId'=>$userId, "imageURL"=>$fullUrl);
} else {
    $arrayToSend = array('status'=>'FAILED','time'=>$time,'body'=>$body,'userId'=>$userId);
}

header('Content-Type:application/json');
echo json_encode($arrayToSend);

Voici une solution utilisant Alamofire 3.0 basée sur la réponse antiblanks:

 let parameters = [
            "par1": "value",
            "par2": "value2"]    

 let URL = "YOUR_URL.php"

 let image = UIImage(named: "image.png")

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

                if let _image = image {
                    if let imageData = UIImageJPEGRepresentation(_image, 0.5) {
                        multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.png", mimeType: "image/png")
                    }
                }

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

            }, encodingCompletion: {

Le téléchargement en plusieurs parties devrait être inclus dans la prochaine version (1.3.0) d'Alamofire. En attendant, en utilisant les informations de ce fil, j'ai créé une classe qui simplifie le téléchargement de fichiers et inclut des paramètres supplémentaires ("entrées" régulières) dans la requête avec un ou plusieurs fichiers. Sans supposer que les fichiers sont d'un type particulier ou l'utilisation de routeurs.

FileUploader.swift:

import Foundation
import Alamofire

private struct FileUploadInfo {
  var name:String
  var mimeType:String
  var fileName:String
  var url:NSURL?
  var data:NSData?

  init( name: String, withFileURL url: NSURL, withMimeType mimeType: String? = nil ) {
    self.name = name
    self.url = url
    self.fileName = name
    self.mimeType = "application/octet-stream"
    if mimeType != nil {
      self.mimeType = mimeType!
    }
    if let _name = url.lastPathComponent {
      fileName = _name
    }
    if mimeType == nil, let _extension = url.pathExtension {
      switch _extension.lowercaseString {

      case "jpeg", "jpg":
        self.mimeType = "image/jpeg"

      case "png":
        self.mimeType = "image/png"

      default:
        self.mimeType = "application/octet-stream"
      }
    }
  }

  init( name: String, withData data: NSData, withMimeType mimeType: String ) {
    self.name = name
    self.data = data
    self.fileName = name
    self.mimeType = mimeType
  }
}

class FileUploader {

  private var parameters = [String:String]()
  private var files = [FileUploadInfo]()
  private var headers = [String:String]()

  func setValue( value: String, forParameter parameter: String ) {
    parameters[parameter] = value
  }

  func setValue( value: String, forHeader header: String ) {
    headers[header] = value
  }

  func addParametersFrom( #map: [String:String] ) {
    for (key,value) in map {
      parameters[key] = value
    }
  }

  func addHeadersFrom( #map: [String:String] ) {
    for (key,value) in map {
      headers[key] = value
    }
  }

  func addFileURL( url: NSURL, withName name: String, withMimeType mimeType:String? = nil ) {
    files.append( FileUploadInfo( name: name, withFileURL: url, withMimeType: mimeType ) )
  }

  func addFileData( data: NSData, withName name: String, withMimeType mimeType:String = "application/octet-stream" ) {
    files.append( FileUploadInfo( name: name, withData: data, withMimeType: mimeType ) )
  }

  func uploadFile( request sourceRequest: NSURLRequest ) -> Request? {
    var request = sourceRequest.mutableCopy() as! NSMutableURLRequest
    let boundary = "FileUploader-boundary-\(arc4random())-\(arc4random())"
    request.setValue( "multipart/form-data;boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    let data = NSMutableData()

    for (name, value) in headers {
      request.setValue(value, forHTTPHeaderField: name)
    }

    // Amazon S3 (probably others) wont take parameters after files, so we put them first        
    for (key, value) in parameters {
      data.appendData("\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }

    for fileUploadInfo in files {
      data.appendData( "\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)! )
      data.appendData( "Content-Disposition: form-data; name=\"\(fileUploadInfo.name)\"; filename=\"\(fileUploadInfo.fileName)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData( "Content-Type: \(fileUploadInfo.mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      if fileUploadInfo.data != nil {
        data.appendData( fileUploadInfo.data! )
      }
      else if fileUploadInfo.url != nil, let fileData = NSData(contentsOfURL: fileUploadInfo.url!) {
        data.appendData( fileData )
      }
      else { // ToDo: report error
        return nil
      }
    }

    data.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    return Alamofire.upload( request, data )
  }

}

Il serait utilisé comme ceci:

// This example uploads a file called example.png found in the app resources

let fileURL = NSBundle.mainBundle().URLForResource("example", withExtension: "png")
let fileUploader = FileUploader()
// we can add multiple files
// this would be equivalent to: <input type="file" name="myFile"/>
fileUploader.addFileURL(fileURL!, withName: "myFile")
// we can add NSData objects directly
let data = UIImage(named: "sample")
fileUploader.addFileData( UIImageJPEGRepresentation(data,0.8), withName: "mySecondFile", withMimeType: "image/jpeg" )
// we can also add multiple aditional parameters
// this would be equivalent to: <input type="hidden" name="folderName" value="sample"/>
fileUploader.setValue( "sample", forParameter: "folderName" )
// put your server URL here
var request = NSMutableURLRequest( URL: NSURL(string: "http://myserver.com/uploadFile" )! )
request.HTTPMethod = "POST"
fileUploader.uploadFile(request: request)

Le code de la réponse de @ antiblank ne fonctionnait pas pour moi. J'ai fait quelques changements et ça marche maintenant:

func urlRequestWithComponents(urlString:String, parameters:NSDictionary) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    //let boundaryConstant = "myRandomBoundary12345"
    let boundaryConstant = "NET-POST-boundary-\(arc4random())-\(arc4random())"
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")


    // create upload data to send
    let uploadData = NSMutableData()

    // add parameters
    for (key, value) in parameters {

        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        if value is NetData {
            // add image
            var postData = value as NetData


            //uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"; filename=\"\(postData.filename)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

            // append content disposition
            var filenameClause = " filename=\"\(postData.filename)\""
            let contentDispositionString = "Content-Disposition: form-data; name=\"\(key)\";\(filenameClause)\r\n"
            let contentDispositionData = contentDispositionString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentDispositionData!)


            // append content type
            //uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) // mark this. 
            let contentTypeString = "Content-Type: \(postData.mimeType.getString())\r\n\r\n"
            let contentTypeData = contentTypeString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentTypeData!)
            uploadData.appendData(postData.data)

        }else{
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

UTILISATION:

let docDir:AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let imagePath = docDir + "/myPic.jpg"

var imageData = NSData(contentsOfFile: imagePath, options: NSDataReadingOptions.DataReadingMappedIfSafe, error: nil)
var parameters = [
            "pic"           :NetData(nsData: imageData!, filename: "customName.jpg"),
            "otherParm"     :"Value"
        ]


    let urlRequest = self.urlRequestWithComponents("http://www.example.com/upload.php", parameters: parameters)

Les NetData de https://github.com/nghialv/Net/blob/master/Net/NetData.swift

Code upload.php:

<?php
// In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
// of $_FILES.

$uploaddir = 'uploads/';
// PS: custom filed name : pic
$uploadfile = $uploaddir . basename($_FILES['pic']['name']);

if (move_uploaded_file($_FILES['pic']['tmp_name'], $uploadfile)) {
   $array = array ("code" => "1", "message" => "successfully");  
} else {
   $array = array ("code" => "0", "message" => "Possible file upload attack!".$_FILES['pic']['name']); 
}

echo json_encode ( $array );

Usage

let rep = (asset as ALAsset).defaultRepresentation()
let ref = rep.fullResolutionImage().takeUnretainedValue()
Photo.upload(UIImage(CGImage: ref)!, filename: rep.filename())
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println(totalBytesWritten)
    }
    .responseJSON { (request, response, JSON, error) in
        println(JSON)
    }

Bien qu'il existe d'autres réponses qui indiquent comment construire manuellement des demandes en plusieurs parties, vous pouvez simplement vous en tenir à AFNetworking. Même s'il est écrit en Objective-C, vous pouvez toujours l'utiliser dans vos projets Swift (voir Swift et Objective-C dans le même projet ). Quoi qu'il en soit, le code Swift pour soumettre une requête en plusieurs parties à l'aide d'AFNetworking est le suivant:

let data = UIImagePNGRepresentation(image)

let manager = AFHTTPSessionManager()

manager.POST(uploadURLString, parameters: nil, constructingBodyWithBlock: { formData in
    formData.appendPartWithFileData(data, name: "image", fileName: "test.png", mimeType: "image/png")
}, success: { operation, responseObject in
    println(responseObject)
}) { operation, error in
    println(error)

Xcode ennuyeux a des problèmes pour reconnaître ce id<AFMultipartFormData>paramètre, formDatadonc vous n'appréciez pas l'achèvement typique du code de l'éditeur de la appendPartWithFileDataméthode ou de ses paramètres, mais lorsque vous le compilez et l'exécutez, cela fonctionne bien.

Vous obtenez 415 en raison du type de contenu manquant dans votre demande. Vous trouverez ci-dessous une solution complète de téléchargement d'images sur Swift 2 et AlamoFire

import UIKit
import Alamofire

class ViewController: UIViewController {

@IBOutlet var imageView: UIImageView!
@IBOutlet var btnUpload: UIButton!
override func viewDidLoad() {
    super.viewDidLoad()
}

func successDataHandler(responseData:String){

    print ("IMAGE UPLOAD SUCCESSFUL    !!!")

}

func failureDataHandler(errorData:String){

    print ("  !!!   IMAGE UPLOAD FAILURE   !!! ")

}

@IBAction func actionUpload(sender: AnyObject) {

    let URL = "http://m8coreapibeta.azurewebsites.net/api/cards/SaveImages"

    let postDataProlife:[String:AnyObject] = ["CardId":(dataCardDetail?.userId)!,"ImageType":1,"ImageData":imageView.image!]

    uplaodImageData(URL, postData: postDataProlife, successHandler: successDataHandler, failureHandler: failureDataHandler)

func uplaodImageData(RequestURL: String,postData:[String:AnyObject]?,successHandler: (String) -> (),failureHandler: (String) -> ()) -> () {

    let headerData:[String : String] = ["Content-Type":"application/json"]

    Alamofire.request(.POST,RequestURL, parameters: postData, encoding: .URLEncodedInURL, headers: headerData).responseString{ response in
        switch response.result {
        case .Success:
            print(response.response?.statusCode)
            successHandler(response.result.value!)
        case .Failure(let error):
            failureHandler("\(error)")
        }
    }
}
}

Ci-dessous sont Swift et Php Code

Code Swift -> Apple Swift version 3.0.1 (swiftlang-800.0.58.6 clang-800.0.42.1) Cible: x86_64-apple-macosx10.9

   class  func upload(jsonObject: AnyObject , files : Array<Any>? = nil  , completionHandler :  CompletionBlock? = nil ,failureHandler : FailureBlock? = nil )
{

    Alamofire.upload(multipartFormData:
        { (multipartFormData) in

            if let  filesO = files
            {
                for i in (filesO.enumerated())
                {
                    let image = UIImage(named: "\(i.element)")

                    let data = UIImageJPEGRepresentation(image!, 1)!

                    multipartFormData.append(data, withName: "imgFiles[]" , fileName: "\( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
                  // imgFiles[] give array in Php Side
                  // imgFiles   will give string in PHP String


                }

            }


            for  (key, value)  in jsonObject as! [String : String]
            {

                 multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)

            }}          
    },
                     to:baseURL)

Code PHP pour obtenir des paramètres et un fichier

Ici, les paramètres sont traités dans $ _Request

Et les fichiers sont gérés dans $ _File

Le format dans les données $ _File (tableau, dictionnaire ou chaîne) dépendra de la requête du côté swift, ici Voir cette ligne dans le code

multipartFormData.append (data, withName: "imgFiles []", fileName: "(NSUUID (). uuidString) .jpeg", mimeType: "image / jpeg")

côté Php withName: "imgFiles []" donne un tableau de nom, format, type

Par exemple

"nom": ["06748B86-478E-421B-8470-6262755AC149.jpeg", "E70269E9-FB54-4BFD-B807-7E418C81540D.jpeg"], "type": ["image / jpeg", "image / jpeg" ], "tmp_name": ["/ tmp / phpz3UAPq", "/ tmp / phpCAPExG"], "error": [0,0], "size": [2779495,2067259]}

Code PHP

 if (isset($_FILES['imgFiles']) and strlen($orderId) > 0) {

        foreach ($_FILES['imgFiles']['tmp_name'] as $key => $tmp_name) {

            $file_name = $key . $_FILES['imgFiles']['name'][$key];
            $file_size = $_FILES['imgFiles']['size'][$key];
            $file_tmp = $_FILES['imgFiles']['tmp_name'][$key];
            $file_type = $_FILES['imgFiles']['type'][$key];
 if (is_dir("$desired_dir/" . $file_name) == false) {
                //move_uploaded_file($file_tmp, "user_data/" . $file_name);
                move_uploaded_file($file_tmp, $desired_dir . "/" .
           $file_name);
            } else {         //rename the file if another one exist
                $new_dir = $desired_dir . "/" . $file_name . time();
                rename($file_tmp, $new_dir);
            }

J'ai pris la réponse d'antiblank et j'ai tout emballé dans une fonction avec le gestionnaire d'achèvement. J'ai pensé que cela pourrait être utile pour quelqu'un. C'est un peu plus `` rugueux '' que la réponse antiblank car je prends simplement une réponse de chaîne du fichier PHP (pas JSON).

Voici comment vous l'appelez:

let imageData = UIImagePNGRepresentation(myImageView.image)

uploadImage("http://www.example.com/image_upload.php", imageData: imageData, subdir: "images", filename: "imageID.png")
    { (req, res, str, err) -> Void in
        // do whatever you want to to for error handling and handeling success
    }

Voici la fonction elle-même:

func uploadImage(urlToPHPFile: String, imageData: NSData, subdir: String, filename: String, completionHandler:(request:NSURLRequest, response:NSURLResponse?, responseString:String?, error: NSError?) -> ()) {

    func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {
        // create url request to send
        var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
        mutableURLRequest.HTTPMethod = Method.POST.rawValue
        let boundaryConstant = "myRandomBoundary12345";
        let contentType = "multipart/form-data;boundary="+boundaryConstant
        mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")

        // create upload data to send
        let uploadData = NSMutableData()

        // add image
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData(imageData)

        // add parameters
        for (key, value) in parameters {
            uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }
        uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        // return URLRequestConvertible and NSData
        return (ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
    }

    let parameters = [
        "subdir" : subdir,
        "filename": filename
    ]
    let urlRequest = urlRequestWithComponents(urlToPHPFile, parameters, imageData)

    AlamoFire.upload(urlRequest.0, urlRequest.1)
        .responseString(completionHandler: { [weak self] (req, res, str, err) -> Void in
            if let strongSelf = self {
                completionHandler(request: req, response: res, responseString: str, error: err)

            }
        }
    )
}

Et voici le fichier php.

$subdir = $_POST['subdir'];
$filename = $_POST["filename"];

$targetPath = $subdir.'/'.$filename;

$moved = move_uploaded_file($_FILES["file"]["tmp_name"], $targetPath );
if ($moved) {
    echo "OK";
}
else {
    echo "Error: file not uploaded";
}
