图片上传在swft 4使用alamofire 4与PHP不工作在更新版本

我做了我的项目与图像上传到服务器使用PHP脚本。它在Swift 2和alamofire上运行良好。

用alamofire 4更新到Swift 4后，上传代码不起作用。

@IBAction func create(_ sender: AnyObject) {

    showLoadingMode (loading: self)

    let name = grpnametf.text
    let defaults = UserDefaults.standard

    let member_id = defaults.object(forKey: "id") as! String
    let country = defaults.object(forKey: "country") as! String


    if (name != "" ){

        self.reachability = Reachability.init()
        if((self.reachability?.connection) != .none)
        {
       // let reachability = Reachability2.reachabilityForInternetConnection()

        //if reachability.isReachable() || reachability.isReachableViaWiFi() || reachability.isReachableViaWWAN(){

        //if (network.reachability.whenReachable != nil) {
            let image : NSData = UIImageJPEGRepresentation(profileimg.image!, 32)! as NSData


          //let picname = "1"
            let grpiconname : String = member_id + name!

            let formattedstring = grpiconname.replacingOccurrences(of: " ", with: "_")

            let parameters = [
                "id" : member_id,
                "g_name" : name!,
                "type" : "ios",
                "country" : country,
                "fileName" : formattedstring+".jpg"

                ]
            let url = "http://www.kidsedin.com/nriconnect/webpage/index.php/App/creategroup"

            Alamofire.request(url, method: .get, parameters: parameters, encoding: URLEncoding.default).responseJSON { response in

                if let j = response.result.value {


                    actInd.stopAnimating()

                    //swifty json

                    // print(j)
                    let result = (j as AnyObject).stringValue
                   // print (result)

                    if result != "0" {

                       // let urlRequest = self.urlRequestWithComponents(urlString: "http://www.kidsedin.com/nriconnect/webpage/index.php/app/pic_upload?grpicon_name="+formattedstring+"&groupid="+result!, parameters: parameters as NSDictionary)

                        //print(urlRequest)

                       // let imageToUploadURL = Bundle.main.url(forResource: "bg", withExtension: "jpg")

                        //let url = "http://www.kidsedin.com/nriconnect/webpage/index.php/app/testpicupload"

                            // Use Alamofire to upload the image

                        print(UIImageJPEGRepresentation(self.profileimg.image!, 1))
                        Alamofire.upload(multipartFormData: { (multipartFormData) in
                            multipartFormData.append(UIImageJPEGRepresentation(self.profileimg.image!, 0.2)!, withName: "photo_path", fileName: formattedstring+".jpg", mimeType: "image/jpeg")
                            for (key, value) in parameters {
                                multipartFormData.append(value.data(using: .utf8)!, withName: key)
                            }
                        }, to:"http://www.kidsedin.com/nriconnect/webpage/index.php/app/testpicupload?grpicon_name="+formattedstring+"&groupid="+result!+"&type=ios")
                        { (result) in
                            switch result {

                                })

                                upload.responseJSON { response in
                                    print(response.result.value)
                                    print("1")
                                }

                            case .failure(let encodingError): break
                                //print(encodingError.localizedDescription)
                            }
                        }
                    }

                    else if result == "0"{

                        let alert = UIAlertController(title: "", message: "Group name already exist", preferredStyle: .alert)
                        let okAction = UIAlertAction(title: "Ok", style: .default, handler:nil)
                        alert.addAction(okAction)

                        self.present(alert, animated: true, completion: nil)


                        actInd.stopAnimating()

                    }else
                    {
                        let alert = UIAlertController(title: "", message: "Group creation failed. Something went wrong", preferredStyle: .alert)

                        actInd.stopAnimating()
                    }
                }

            }

        else

            let okAction = UIAlertAction(title: "Ok", style: .default, handler: nil)

            alert.addAction(okAction)

            self.present(alert, animated: true, completion: nil)


            actInd.stopAnimating()
        }
    }

    else{

        if( name == "" ){

            let alert = UIAlertController(title: "", message: "Name field is empty", preferredStyle: .alert)
            let okAction = UIAlertAction(title: "Ok", style: .default, handler: nil)

            alert.addAction(okAction)

            self.present(alert, animated: true, completion: nil)

            actInd.stopAnimating()
        }

    }
}

以上是我更新的代码。请建议我应该怎么做来解决这个错误。或提供我改变这个图像上传使用PHP脚本的解决方案。
