Upload image to AWS S3 using alamofire upload - ios

Question

I am trying to upload jpeg image to AWS using upload function. But i am getting the following error :
nw_endpoint_handler_add_write_request [29.1 52.92.250.6:443 failed socket-flow (satisfied)] cannot accept write requests
Some help would be of great use. Here is the code i am using (params is of type Data)
let request = Alamofire.upload(params, to: url, method: .put, headers: ["Content-Type":"image/jpeg"])
request.responseJSON { (responseJson) in
switch responseJson.result {
case .success:
print("Success: \(responseJson.result.value)")
break
case .failure:
print("Call failed: \(responseJson.result.value)")
break
default:
print("____")
}
}

Answer 1

Probably best to use Amazon's own SDK for doing this.

Answer 2

Try with this:
Swift 3.x:
func uploadImageWith(parameter params:Dictionary<String,String>,image:UIImage?,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 image != nil {
if let imgData = UIImageJPEGRepresentation(image!, 0.5) {
multipartFormData.append(imgData, withName: "photo_upload", fileName: "file.png", mimeType: "image/png")
}
}
}, 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)
}
}
}
Usage:
uploadImageWith(parameter: ["key":"value"], image: UIImage(named:"demo")) { (response) in
if response != nil {
print(response)
} else {
print("Something went wrong")
}
}
