Send image AND parameters to web server with Swift 3

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()
}

    var mimetype = "image/jpg"

    //let defFileName = fileNameObj

    return body
