Hochladen von Bild auf Server mit UIImagePickerController zeigt Dateityp, den Sie hochladen möchten, ist nicht erlaubt (Swift/iOS)

Question

Ich möchte das Bild aus der Fotobibliothek in einem Simulator auf meinem Server hochladen. Aber jedes Mal bekomme ich diese JSON-Antwort:

Here the jsonObject is Optional({ 
    status = "The filetype you are attempting to upload is not allowed."; 
}) 

Ich teste dies in einem Simulator. Welche Art von Dateityp ist nicht erlaubt? Ich verstehe es nicht.

Dies ist mein Code-Block:

self.headerImageView.image=info[UIImagePickerControllerOriginalImage] as? UIImage 

let image1=info[UIImagePickerControllerOriginalImage] as? UIImage 

let imgdata : NSData = UIImagePNGRepresentation(image1!)! 

let appDelegate1 = UIApplication.sharedApplication().delegate as! AppDelegate 

UserRoomid=appDelegate1.roomlistid as String 


let request:NSMutableURLRequest = NSMutableURLRequest(URL: NSURL(string:"\(liveurl)rooms/image_upload?user_id=\(webservice8)")!) 

var session = NSURLSession.sharedSession() 

request.HTTPMethod = "POST" 

let boundary = generateBoundaryString() 

let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary) 

request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")    

let body = NSMutableData() 
body.appendData(NSString(format: "\r\n--%@\r\n",boundary).dataUsingEncoding(NSUTF8StringEncoding)!) 

body.appendData(NSString(format:"Content-Disposition: form-data; name=\"title\"\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!) 

body.appendData("Hello World".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)!) 

body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!) 

body.appendData(NSString(format:"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"bklblk.jpg\"\r\n").dataUsingEncoding(NSUTF8StringEncoding)!) 

body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!) 

body.appendData(imgdata) 


body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!) 


request.HTTPBody = body 

let operation : AFHTTPRequestOperation = AFHTTPRequestOperation(request: request) 

operation.responseSerializer.acceptableContentTypes = NSSet(object: "text/html") as Set<NSObject> 

operation.setCompletionBlockWithSuccess ({ 

    (operation : AFHTTPRequestOperation!, responseObject: AnyObject!) in 

    let response : NSString = operation.responseString! 

    print("success is \(response)") 

    print("Here the responseObject for success is \(responseObject)") 
)} 

Hier ist mein Server-Code:

    if ($status != "error")  
    { 
     if(!is_dir($this->path.'/'.$id))

      $config3['height'] = 320; 

      $this->load->library('image_lib'); 

      $this->image_lib->initialize($config3);

      { 
       $resize = $this->image_lib->display_errors();

Versuch als Server-Code zu verwenden

if(isset($_FILES['photo']['tmp_name'])) { 
       $file = $_FILES['photo']['tmp_name']; 
       if (move_uploaded_file($file, ROOT_DIRECTORY.'../../../../images/driver_'.$driver->id.'.jpg')) { 
     //success 
       } 
      }
