如何通过Alamofire发送图像文件？

Question

I want to send an image to the server and I'm using this code:

Alamofire.upload(
            .POST,
            "https://api.mysite.com/image",
            multipartFormData: { multipartFormData in
                if let _ = image {
                    if let imageData = UIImageJPEGRepresentation(image!, 1.0) {
                        multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.png", mimeType: "image/png")
                    }                      
                }
            }, encodingCompletion: {
                encodingResult in

                switch encodingResult {
                case .Success(let upload, _, _):
                    upload.responseJSON { response in
                        switch response.result {
                        case .Success:
                            debugPrint(response)
                        case .Failure(let error):
                            print(error)
                        }

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

but in response I get:

[Result]: SUCCESS: (
"",
    {
    file =         {
        error = 1;
        name = "file.png";
        size = 0;
        "tmp_name" = "";
        type = "";
    };

so my file is not sending to the server. What is the wrong in my code?

let imageData = UIPNGRepresentation(image)!

Alamofire.upload(imageData, to: "https://httpbin.org/post").responseJSON { response in
  debugPrint(response) 
}
