ios - Facebook 图形 API 问题

Question

我正在实现 facebook graph APi 以获取帖子列表，但我在这这是我的代码中遇到错误

var Requset : FBSDKGraphRequest

        print("\(FBSDKAccessToken.current())")

        let acessToken = String(format:"%@", FBSDKAccessToken.current().tokenString) as String

        print("\(acessToken)")

        let parameters1 = ["access_token":FBSDKAccessToken.current().tokenString]


        Requset  = FBSDKGraphRequest(graphPath:"me/?fields=feed{message,full_picture,id,application,likes{name,pic_crop},comments{message,from,created_time},created_time}", parameters:parameters1, httpMethod:"GET")

        Requset.start(completionHandler: { (connection, result, error) -> Void in

            //MBProgressHUD.hideHUDForView(appDelegate.window, animated: true)

            if ((error) != nil)
            {
                print("Error: \(error)")
            }
            else
            {
                print("fetched user: \(result)")

                //var dataDict: AnyObject = (result! as AnyObject).object(forKey: "data")!

            }

我在这个错误中遇到错误如下

错误：可选（错误域=NSURLErrorDomain 代码=-1002“不支持的 URL”UserInfo={NSUnderlyingError=0x60000005fbf0 {错误域=kCFErrorDomainCFNetwork 代码=-1002“（null）”}，NSErrorFailingURLStringKey=（null）？

谁能告诉我如何解决这个问题
