Swift 4 with Alamofire 4
=================================
let isConnected = connectivity.isConnectedToInternet()
func updateProfile(firstName:String,lastName:String ,imageData:Data?,completion: @escaping (isValidUser)->()) {
if self.isConnected {
var parameters : [String:String] = [:]
parameters["auth_key"] = loginUser?.authKey!
parameters["User[first_name]"] = firstName
parameters["User[last_name]"] = lastName
let url = "\(baseUrl)\(basicAuthenticationUrl.updateProfile)"
print(url)
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in parameters {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
if let data = imageData {
multipartFormData.append(data, withName: "image_url", fileName: "image.png", mimeType: "image/png")
}
}, usingThreshold: UInt64.init(), to: url, method: .post) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print("Succesfully uploaded = \(response)")
if let err = response.error{
print(err)
return
}
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")
}
}
}
}
As in Swift 3.x for upload image with parameter we can use below alamofire upload method-
static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {
let imageData = UIImageJPEGRepresentation(imageFile , 0.5)
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")
for key in parameters.keys{
let name = String(key)
if let val = parameters[name!] as? String{
multipartFormData.append(val.data(using: .utf8)!, withName: name!)
}
}
}, to:inputUrl)
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (Progress) in
})
upload.responseJSON { response in
if let JSON = response.result.value {
completion(JSON)
}else{
completion(nilValue)
}
}
case .failure(let encodingError):
completion(nilValue)
}
}
}
> Note:-Additionally if our parameter is array of key-pairs then we can
> use
var arrayOfKeyPairs = [[String:Any]]()
let JSON = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
let jsonPrasatation = String(data: JSON!, encoding: .utf8)
