    if(imageData==nil)  { return; }

    request.httpBody = createBodyWithParameters(parameters: param, filePathKey: "file", imageDataKey: imageData! as NSData, boundary: boundary) as Data

    myActivityIndicator.isHidden = false
    myActivityIndicator.startAnimating();

    }

    task.resume()
}


func createBodyWithParameters(parameters: [String: String]?, filePathKey: String?, imageDataKey: NSData, boundary: String) -> NSData {
    let body = NSMutableData();

    let filename = "user-profile.jpg"
    let mimetype = "image/jpg"

    body.appendString(string: "--\(boundary)\r\n")
    body.appendString(string: "Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")

    body.append(imageDataKey as Data)
    body.appendString(string: "\r\n")



    body.appendString(string: "--\(boundary)--\r\n")

    return body
}



func generateBoundaryString() -> String {
    return "Boundary-\(NSUUID().uuidString)"
}

func webServiceImageUploadForMyProfile(image:UIImage,url:String,method:HTTPMethod,parameters : [String:AnyObject]?,completionHandler:@escaping (JSON?,String)->Void) {

    let url = try! URLRequest(url: url, method: .post, headers: nil)
    Alamofire.upload(multipartFormData:{ multipartFormData in
        if  let imageData = UIImageJPEGRepresentation(image, 0.6) {
            multipartFormData.append(imageData, withName: "image", fileName: "Profile.png", mimeType: "image/png")
        }
        for (key, value) in parameters! {
            multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue)!, withName: key)
        }
