How to upload multipart with this data - ios

Question

I want to send this data in the form of multipart to server with image/video. I have image/video data in byte data form (NSData or Data)
{"mediauploadata":
{
"type":"poll",
"server_token":"03f0e635b4c01b9f398de393259de8650b54c85c24f49998af50593643f559230d95e8e605612653769f4871b543e25d48bf",

}
}

Answer 1

I have created a function for Multipart Upload using Alamofire.
Call this function passing Web service URL , Parameters and your image.
func WSPostAPIMultiPart(_ aStrULR:String,
param: [String: Any],
image : UIImage?,
controller: UIViewController,
successBlock: #escaping (_ response:[String : Any]?) -> Void,
failureBlock: #escaping (_ error: Error?) -> Void) {
var dictHeaders : HTTPHeaders = [String : String]()
if (Alamofire.NetworkReachabilityManager()?.isReachable)!{
Alamofire.upload(
multipartFormData: { MultipartFormData in
let JSONData: Data? = try? JSONSerialization.data(withJSONObject: param, options: .prettyPrinted)
MultipartFormData.append(JSONData!, withName: "json")
if image != nil{
MultipartFormData.append(UIImageJPEGRepresentation(image!, 0.5)!, withName: "profile_image",fileName: "image.jpeg", mimeType: "image/jpeg")
// withName : You will pass the key name required by your server
}
}, to: aStrULR ,method : .post , headers : dictHeaders) { (result) in
switch result {
case .success(let upload, _, _):
upload.responseJSON { response in
if let value = response.result.value {
let dictResponse = JSON(value).dictionaryObject
successBlock(dictResponse)
}
}
case .failure(let error):
failureBlock(error)
}
}
}else{
print("NO INTERNET CONNECTIVITY")
}
}
For Video: Just pass videoURL one extra parameter and append as :
MultipartFormData.append(videoUrl, withName: "profileVideo", fileName: "video.mp4", mimeType: "video/mp4")
Hope it helps :)

func uploadDataWith(parameter params:Dictionary<String,String>,data:Data?,isImage:Bool,handler:#escaping ((Dictionary<String,Any>?) -> Void)) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in params {
multipartFormData.append(value.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: key)
}
if data != nil && isImage {
multipartFormData.append(data, withName: "photo_upload", fileName: "file.png", mimeType: "image/png")
}
if data != nil && !isImage {
multipartFormData.append(data, withName: "video_upload", fileName: "file.mp4", mimeType: "video/mp4")
}
}, to: "http://") { (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("Json Response: \(jsonDict)")
handler(jsonDict)
print(jsonDict,(response.response!.statusCode))
}
else{
print(response.response!.statusCode)
handler(nil)
}
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):
print(response.response!.statusCode)
print_debug(error)
handler(nil)
break
}
}
case .failure(let encodingError):
print(encodingError)
}
}
}
