swift - Swift 3中如何处理FBSDKGraphRequest的响应数据

Question

我已经集成了 FB 最新的 SDK(非 swift)并且登录工作正常。我只需要知道如何解析图形响应数据，因为它不是有效的 JSON

工作代码:

     func configureFacebook()
        {
            login.readPermissions = ["public_profile", "email", "user_friends"];
            login.delegate = self
        }


func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
    print("Login buttoon clicked")
    let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"first_name,email, picture.type(large)"])

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

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

        }
    })
}

输出:

Login button clicked
Optional({
    "first_name" = KD;
    id = 10154CXXX;
    picture =     {
        data =         {
            "is_silhouette" = 0;
            url = "https://scontent.xx.fbcdn.net/v/t1.0-1/p200x200/XXXn.jpg?oh=a75a5c1b868fa63XXX146A";
        };
    };
})

那么我应该将上述数据转换成什么格式来获取 URL 或 first_name 等值？

我也尝试转换为 NSDictionary 并得到错误:

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
        print("Login buttoon clicked")
        let graphRequest:FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"first_name,email, picture.type(large)"])

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

            if ((error) != nil)
            {
                print("Error: \(error)")
            }
            else
            {
                do {

                let fbResult = try JSONSerialization.jsonObject(with: result as! Data, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
                print(fbResult.value(forKey: "name"))


                } catch {
                    print(error)
                }

            }
        })
    }

Answer 1

您可以简单地按照以下方式进行操作:

let data:[String:AnyObject] = result as! [String : AnyObject]
print(data["first_name"]!)

swift 3:

安全解包 & Any 而不是 AnyObject

if let data = result as? [String:Any] {

}
