How to upload image using Alamofire with token&parameters? - ios

Question

I use Alamofire to upload images, however the upload is unsuccessful. I also bring token & parameters to server.
I don't know whether I add token & parameters correctly or not.
What's wrong with me to using Alamofire?
Have any suggestion?
Thanks.
func uploadWithAlamofire(image:UIImage, imageData:Data, imageUrl:URL) {
let parameters = ["avatar":imageData]
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imageData, withName: user.id, fileName: "\(user.id).jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value, withName: key)
}
}, to: apiUrl , method: .put, headers: ["Authorization": "Bearer \(token)"],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response { [weak self] response in
guard self != nil else {
return
}
debugPrint(response)
}
case .failure(let encodingError):
print("error:\(encodingError)")
}
})
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
photoImage = info[UIImagePickerControllerOriginalImage] as! UIImage
photoImageView.image = photoImage
let imageName:String = user.id + ".jpg"
let documentsPath = NSHomeDirectory().appending("/Documents/Icon/")
let imagePath = documentsPath.appending(imageName)
let imageUrl = URL(fileURLWithPath: imagePath)
print("imageUrl is here:\(imageUrl)")
let imageData:Data = UIImageJPEGRepresentation(photoImage, 0.001)!
do {
try imageData.write(to: imageUrl,options: .atomic)
} catch let error {
print(error)
}
uploadWithAlamofire(image: photoImage, imageData: imageData, imageUrl: imageUrl)
self.dismiss(animated: true, completion: nil)
}

Try this:
func uploadImageWith(param params:Dictionary<String,String>,image:UIImage?,handler:#escaping ((Dictionary<String,Any>?,Int) -> Void)) {
// let keyJson = "json".dataUsingEncoding(NSUTF8StringEncoding)!
print("Params:\(params)")
let BASE_URL = "http://"
Alamofire.upload(
multipartFormData: { multipartFormData in
for (key, value) in params {
multipartFormData.append(value.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: key)
}
if image != nil{
let imgData = UIImageJPEGRepresentation(image!, 0.5)
if imgData != nil {
multipartFormData.append(imgData!, withName: "photo_upload", fileName: "file.png", mimeType: "image/png")
}
}
},
to: BASE_URL,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
switch response.result {
case .success:
if let jsonDict = response.result.value as? Dictionary<String,Any> {
print_debug("Json Response: \(jsonDict)") // serialized json response
handler(jsonDict,(response.response!.statusCode))
}
else{
handler(nil,(response.response!.statusCode))
}
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Server Response: \(utf8Text)") // original server data as UTF8 string
}
break
case .failure(let error):
handler(nil,(response.response!.statusCode))
break
}
}
case .failure(let encodingError):
print(encodingError)
}
}
)
}
USE
uploadImageWith(param: ["key":"value"], image: UIImage(name:"icon")) { (response, statusCode) in
print(response)
}
You have to pass the params and image object and you get the response as a Dictionary object in closure.

Use this function to upload image to the server with token and parameters
func uploadImageAndData(){
var parameters = [String:AnyObject]()
parameters = ["token": token,
"Name": Name]
let URL = "http://yourserviceurl/"
let image = UIImage(named: "image.png")
Alamofire.upload(.POST, URL, multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 0.6) {
multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: {
encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
print("s")
upload.responseJSON {
response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
case .Failure(let encodingError):
print(encodingError)
}
})}
Works for the Alamofire 3.0+
