Swift - Alamofire - upload file from photolibrary - swift

Question

I'm trying to implement an upload from my photo-library with Alamofire:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
guard let image = info[UIImagePickerControllerOriginalImage] as? UIImage else {
return
}
let documentDirectory: NSString = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first! as NSString
let imageName = "temp"
let imagePath = documentDirectory.appendingPathComponent(imageName)
if let data = UIImageJPEGRepresentation(image, 80) {
do {
try data.write(to: URL(fileURLWithPath: imagePath), options: .atomic)
} catch let error {
print(error)
}
}
Alamofire.upload(.POST, "\(self.app_url)/user/upload", multipartFormData: { formData in
let filePath = NSURL(fileURLWithPath: image)
formData.appendBodyPart(fileURL: filePath, name: "upload")
formData.appendBodyPart(data: "Alamofire".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name: "test")
}, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success:
print("SUCCESS")
case .Failure(let error):
print(error)
}
})
self.dismiss(animated: true, completion: nil)
}
And it prints:
Ambiguous reference to member 'upload(_:to:method:headers:)'
Can anybody explain me how to resolve this issue?
Thanks and Greetings!

Answer 1

In Swift 3 and Alamofire 4
Here is the Full Implementation of how to upload using Alamofire
Add the Following to your ViewController Class:
UIImagePickerControllerDelegate and UINavigationControllerDelegate
Create A Button:
First Create a button and implement the Following method in it for picker view
#IBAction func btnSelectProfileImageClicked(_ sender: Any) {
let ImagePicker = UIImagePickerController()
ImagePicker.delegate = self
ImagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
self.present(ImagePicker, animated: true, completion: nil)
}
Then Implement the following UIPicker Methods:
func imagePickerController( _ picker: UIImagePickerController,didFinishPickingMediaWithInfo info:[String : Any] )
{Imgprofile.image = info[UIImagePickerControllerOriginalImage] as? UIImage
self.dismiss(animated: true, completion: nil)}
Make Another Button Which Passes the data to URL using Alamofire and Give an #IBAction outlet to it to it :
Enter Following Data to it
#IBAction func btnUpdateProfileSelected(_ sender: Any) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(self.Imgprofile.image!, 1)!, withName: "Prescription", fileName: "Profile_Image.jpeg", mimeType: "image/jpeg")
}, to:" Your URL Here where You want to Upload")
{ (result) in
switch result {
case .success(let upload, _, _):
print(result)
upload.uploadProgress(closure: { (progress) in
print(progress)
})
upload.responseJSON { response in
//print response.result
print(response);
}
case .failure(let encodingError):
print(encodingError);
}
}
}
Thats all
Hope This helps
For Full sample code or any doubts please comment. I will provide you
the sample code for this. Which Includes the Fetching as well as
upload data using Alamofire.
