Send image AND parameters to web server with Swift 3 - swift3

Question

I am sending image to server successfully but fileName is showing Nil or [].How to slove this issue. I shared my source code also.
#IBAction func upLoadBtn(_ sender: Any)
{
let myUrl = NSURL(string: "http://digilegal.neviton.com:8080/Legal-app/uploadGenDoc");
//let myUrl = NSURL(string: "http://www.boredwear.com/utils/postImage.php");
let request = NSMutableURLRequest(url:myUrl! as URL)
request.httpMethod = "POST"
let obj1:String = String(masterIdStored)
let obj2:String = String(associateStored)
let obj3:String = String(associateNameStored)
print("obj1 is:\(obj1)")
let param = [
"masterClientId" : obj1,
"uploaderId" : obj2,
"uploaderName" : obj3
] as [String : Any]
print("param is:\(param)")
let boundary = generateBoundaryString()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let imageData = UIImageJPEGRepresentation(imageView.image!, 1)
if(imageData==nil) { return; }
request.httpBody = createBodyWithParameters(parameters: param as! [String : String], filePathKey: "file", imageDataKey: imageData! as NSData, boundary: boundary) as Data
// myActivityIndicator.startAnimating();
let task = URLSession.shared.dataTask(with: request as URLRequest) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
// You can print out response object
print("******* response = \(String(describing: response))")
// Print out reponse body
let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("****** response data = \(responseString!)")
let respVO:[RespVo] = Mapper<RespVo>().mapArray(JSONString: responseString! as String)!
print("responseString = \(respVO)")
let successResp = respVO[0].response
let statusResp = "Documents saved successfully"
if successResp! == (statusResp as NSString) as String {
DispatchQueue.main.async(execute: { () -> Void in
// self.submitOutlet.isUserInteractionEnabled = false
let ViewController = self.storyboard?.instantiateViewController(withIdentifier: "CustomSecondAlertViewController") as! CustomSecondAlertViewController
ViewController.view.backgroundColor = UIColor.black.withAlphaComponent(0.6)
self.addChildViewController(ViewController)
self.view.addSubview(ViewController.view)
self.dismiss(animated: false, completion: nil)
})
}
}
task.resume()
}
func createBodyWithParameters(parameters: [String: String]?, filePathKey: String?, imageDataKey: NSData, boundary: String) -> NSData {

}
//let newObj = "manu.jpg"
//let manuObj = fileNameLabel.text
body.appendString(string: "--\(boundary)\r\n")
var mimetype = "image/jpg"
//let defFileName = fileNameObj
let imageData = UIImageJPEGRepresentation(imageView.image!, 1)
print("defFileName is :\(String(describing: imageData))")
let fnamed = fileNameObj
print("fnamed is:\(fnamed)")
