Uploading a file problem with Alamofire Swift 5?

Question

I want to upload a simple file using,

pod 'Alamofire', '~> 5.0.0-rc.3'

But I cannot see the file in the linux host's folder.

upload.php file:

<?php
   if(isset($_FILES['image'])){
      $errors= array();
      $file_name = $_FILES['image']['name'];
      $file_size =$_FILES['image']['size'];
      $file_tmp =$_FILES['image']['tmp_name'];
      $file_type=$_FILES['image']['type'];
      $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));

      $extensions= array("jpeg","jpg","png");

      if(in_array($file_ext,$extensions)===false){
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if($file_size > 2097152){
         $errors[]='File size must be excately 2 MB';
      }

      if(empty($errors)==true){
         move_uploaded_file($file_tmp,"images/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }
?>

Swift file:

    func upload(image: UIImage,
                progressCompletion: @escaping (_ percent: Float) -> Void,
                completion: @escaping (_ result: Bool) -> Void) {
        guard let imageData = image.jpegData(compressionQuality: 0.5) else {
        print("Could not get JPEG representation of UIImage")
        return
      }

      AF.upload(
        multipartFormData: { multipartFormData in
          multipartFormData.append(imageData,
                                   withName: "imagefile",
                                   fileName: "image.jpg",
                                   mimeType: "image/jpeg")
        },
        to: "http://website.com/upload.php", usingThreshold: UInt64.init(), method: .post)

        .uploadProgress { progress in
             progressCompletion(Float(progress.fractionCompleted))
        }
        .response { response in
            debugPrint(response)
        }

    }

    @IBAction func getStartedBtnClicked(_ sender: Any) {

        upload(
            image: UIImage(named: "uploadFile.png")!,
          progressCompletion: { [weak self] percent in
            guard let _ = self else {
              return
            }
            print("Status: \(percent)")
          },
          completion: { [weak self] result in
            guard let _ = self else {
              return
            }
        })
    }

When use to: area in Swift code as " https://httpbin.org/post ":

Status: 1.0
...
[Data]: 19034 bytes
[Network Duration]: 0.9285140037536621s
[Serialization Duration]: 0.0s
[Result]: success(Optional(19034 bytes))

For my custom website's upload.php the result is:

Status: 1.0
...
[Data]: None
[Network Duration]: 0.3820209503173828s
[Serialization Duration]: 0.0s
[Result]: success(nil)

Even simplest block from Alamofire:

        if let fileURL = Bundle.main.url(forResource: "uploadFile", withExtension: "png") {
            AF.upload(fileURL, to: "http://website.com/upload.php").responseJSON { response in
                debugPrint(response)
            }
        }

I'm getting inputDataNilOrZeroLength error:

[Request Body]: 
None
[Response]: 
[Status Code]: 200
[Headers]:

[Result]: failure(Alamofire.AFError.responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength))

At the top of upload.php works from web with below page:

<?php
   if(isset($_FILES['image'])){
      $errors= array();
      $file_name = $_FILES['image']['name'];
      $file_size =$_FILES['image']['size'];
      $file_tmp =$_FILES['image']['tmp_name'];
      $file_type=$_FILES['image']['type'];
      $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));

      $extensions= array("jpeg","jpg","png");

      if(in_array($file_ext,$extensions)=== false){
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if($file_size > 2097152){
         $errors[]='File size must be excately 2 MB';
      }

      if(empty($errors)==true){
         move_uploaded_file($file_tmp,"images/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }
?>
<html>
   <body>

      <form action="" method="POST" enctype="multipart/form-data">
         <input type="file" name="image" />
         <input type="submit"/>
      </form>

   </body>
</html>

I couldn't find a way even simple file uploadings. What I'm missing that point? It would be great if someone explain it.

Later on, I should configure it for uploading video files too. Is there any configuration advices for that?

Answer 1

The filename you look for in server is $_FILES['image'] and the file name you send with request is imagefile .Try changing the multipartFormData appending to as follows

multipartFormData.append(imageData,
                         withName: "image",
                         fileName: "image.jpg",
                         mimeType: "image/jpeg")
