Alamofire Multiform Upload Image with Parameters - ios

Question

I'm using Alamofire to upload image on server, this method working fine and I have already used in many projects.
I have used following code to upload image on my server using multiform data.
Alamofire.upload( multipartFormData: { multipartFormData in
for (key, value) in parameters {
if let data = (value as! String).data(using: .utf8) {
multipartFormData.append(data, withName: key)
}
}
let imageData = image?.pngData()
multipartFormData.append(imageData!, withName: "profile_image", fileName: "profileImage", mimeType: "")
}, to: getURL(.addProfile), headers: getHeaders(), encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response(completionHandler: { (defaultDataResponse) in
guard let httpResponse = defaultDataResponse.response else {
completion(nil, defaultDataResponse.error)
return
}
if httpResponse.statusCode == 200 {
do {
let genericModel = try JSONDecoder().decode(ProfileImageModel.self, from: defaultDataResponse.data!)
completion(genericModel, nil)
} catch {
completion(nil, error)
}
} else {
completion(nil, defaultDataResponse.error)
}
})
case .failure(let encodingError):
completion(nil, encodingError)
}
})
This works fine.
My issue is here, where extra parameter passing in api.
for (key, value) in parameters {
if let data = (value as! String).data(using: .utf8) {
multipartFormData.append(data, withName: key)
}
}
Above code will convert string value to data and append to multipartFormData. And it's works for following type of request structure.
{
"first_name": "ABC",
"last_name": "XYZ",
"bio": "iOS Developer"
}
What to do when I have following type of request structure?
{
"first_name": "ABC",
"last_name": "XYZ",
"bio": "iOS Developer"
"location": {
"full_address": "My Location",
"latitude": "23.0000",
"longitude": "76.0000"
}
}
Please help to achieve this.

Use this function
func requestUploadImage(_ strURL : String, imageData : Data? ,params : [String : AnyObject]?, headers : [String : String]?, success:#escaping (NSDictionary) -> Void, failure:#escaping (Error) -> Void){
// let params = ["id": "101", "name": "Navin", "timezone": "2018-07-26 03:17:06" , "image": imageData] as [String : AnyObject]
//
// CommonMethodsModel.showProgrssHUD()
let url = URL(string: baseURL + strURL)!
let parameters = params //Optional for extra parameter
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imageData!, withName: "image",fileName: "file.jpeg", mimeType: "image/jpeg")
print(imageData , params)
for (key, value) in parameters! {
multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue)!, withName: key)
} //Optional for extra parameters
},
usingThreshold: UInt64.init(), to:url, method: .post)
{ (result) in
// CommonMethodsModel.HidePrgressHUD()
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON { response in
print(response.result.value)
success(response.result.value as! NSDictionary )
}
case .failure(let encodingError):
print(encodingError)
}
}
}
