image bytes upload with request parameter swift 4 - swift4

Question

URL = https://test...com/camimage.aspx
Method Type : Post
Request Parameter :
Header Parameter [“UserID”]
Image Bytes
I got only above info with url and post request in multipart form data. I tried with swift4 multipart but not able to achieve the expected result.
Updated Question with Code and Log
func UploadRequest()
{
let url = URL(string: "https://...com/webcam/camimage.aspx")
let request = NSMutableURLRequest(url: url!)
request.httpMethod = "POST"
let boundary = generateBoundaryString()
request.addValue("UserID", forHTTPHeaderField: "110159")
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
if (imageView.image == nil)
{
return
}
let image_data = UIImagePNGRepresentation(imageView.image!)
if(image_data == nil)
{
return
}
let body = NSMutableData()
let fname = "test.png"
let mimetype = "image/png"
body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
body.append("Content-Disposition:form-data; name=\"uploaded_file\"; filename=\"\(fname)\"\r\n".data(using: String.Encoding.utf8)!)
body.append("Content-Type: \(mimetype)\r\n\r\n".data(using: String.Encoding.utf8)!)
body.append(image_data!)
body.append("\r\n".data(using: String.Encoding.utf8)!)
body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)
request.httpBody = body as Data
let session = URLSession.shared
let task = session.dataTask(with: request as URLRequest, completionHandler: {
(
data, response, error) in
guard ((data) != nil), let _:URLResponse = response, error == nil else {
print("error")
return
}
if let dataString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
{
print(dataString)
}
})
task.resume()
}
func generateBoundaryString() -> String
{
return "*****"
}
I am putting Android Code also. It may help to analysis
FileInputStream fileInputStream = new FileInputStream(selectedFile);
URL url = new URL(SERVER_URL);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);//Allow Inputs
connection.setDoOutput(true);//Allow Outputs
connection.setUseCaches(false);//Don't use a cached Copy
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("ENCTYPE", "multipart/form-data");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
connection.setRequestProperty("uploaded_file",selectedFilePath);
connection.setRequestProperty("UserID", "110159");
//creating new dataoutputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
//writing bytes to data outputstream
dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ selectedFilePath + "\"" + lineEnd);
dataOutputStream.writeBytes(lineEnd);
//returns no. of bytes present in fileInputStream
bytesAvailable = fileInputStream.available();
//selecting the buffer size as minimum of available bytes or 1 MB
bufferSize = Math.min(bytesAvailable,maxBufferSize);
//setting the buffer as byte array of size of bufferSize
buffer = new byte[bufferSize];
//reads bytes from FileInputStream(from 0th index of buffer to buffersize)
bytesRead = fileInputStream.read(buffer,0,bufferSize);
//loop repeats till bytesRead = -1, i.e., no bytes are left to read
while (bytesRead > 0){
//write the bytes read from inputstream
dataOutputStream.write(buffer,0,bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable,maxBufferSize);
bytesRead = fileInputStream.read(buffer,0,bufferSize);
}
dataOutputStream.writeBytes(lineEnd);
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
Log.i(TAG, "Server Response is: " + serverResponseMessage + ": " + serverResponseCode);
//response code of 200 indicates the server status OK
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
#Override
public void run() {
tvFileName.setText("File Upload completed.\n\n You can see the uploaded file here: \n\n" + "http://coderefer.com/extras/uploads/"+ fileName);
}
});
}
//closing the input and output streams
fileInputStream.close();
dataOutputStream.flush();
dataOutputStream.close();
I able to upload image via postman. Still not able to configured to upload via swift code.
Please check the attached two postman webapi chrome tool screenshots. Hope expert could help me out..

use this pod : https://github.com/Alamofire/Alamofire
Ref : https://gist.github.com/DejanEnspyra/5bae2a301b2b2bb5de3109344345617f
func requestWith(endUrl: String, imageData: Data?, parameters: [String : Any], onCompletion: ((JSON?) -> Void)? = nil, onError: ((Error?) -> Void)? = nil){
let url = "http://google.com" /* your API url */
let headers: HTTPHeaders = [
/* "Authorization": "your_access_token", in case you need authorization header */
"Content-type": "multipart/form-data"
]
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", fileName: "image.png", mimeType: "image/png")
}
}, usingThreshold: UInt64.init(), to: url, method: .post, headers: headers) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print("Succesfully uploaded")
if let err = response.error{
onError?(err)
return
}
onCompletion?(nil)
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")
onError?(error)
}
}
}
