Question

我正在使用Facebook C＃SDK的最新SDK，即5.0.9 Beta 我在页面中有一个文本框按钮，假设在用户Wall中发布文本。但问题是当我点击按钮时页面被重定向到就像是 http://localhost:5000/facebookredirect.axd?code=JU1q_vSj13WRn1wIjHjCZRF5iDy_xvkFUppxADeS0F0.eyJpdiI6InJwejVVWXpJY1RqV0VaY1JjTl92ZGcifQ.KSa0B1ax1qCZZ-K_oXLmAZR8lyknWDRY9ieWxuLIZqXedUzb1WQH_FrcMF98VO6U1Dk5KIo4dz4AMdBxtfrUUH0ucgOoPC6_7Zb03WsIgY2fF84L-0s3A7m3f971sJUS4nQyRGDZ_-8oPuO0K0dTPg&state=eyJyIjoiaHR0cDovL2FwcHMuZmFjZWJvb2suY29tL3Rlc3RhcHBfdGVzdGluZy9Ib21lL0Fib3V0P0xlbmd0aD0zIn0

然后再次重定向到我的应用程序URL中间我没有在控制器中获取任何数据值显示为null。

在分析HTTP调用后，我发现内容是

<html><head><script type="text/javascript">

top.location =“http://www.facebook.com/dialog/oauth/?scope=user_about_me,friends_about_me,publish_stream&state=eyJyIjoiaHR0cDovL2FwcHMuZmFjZWJvb2suY29tL3Rlc3RhcHBfdGVzdGluZy9ob21lL0Fib3V0In0&client_id=218380811509677&redirect_uri=http://localhost:5000/facebookredirect个.axd“;

</script></head><body></body></html>

我正在使用Ajax，但行为也是正常的。

它似乎像授权每次通话一样。我是否需要实施Oauth 2.0。

我正在为MVC3使用示例APP。谁能告诉我什么出错？

Answer 1

当您使用FacebookAuthorizeAttribute中的Facebook.Web.Mvc时，这种情况很常见。至少，你的响应代码让我假设oauth握手不能正常工作（虽然你得到了“代码”，你忘了用它获得“access_token”）

如果您使用的是FacebookAuthorizeAttribute，请检查您是否在facebook-developer-app中进行app-settings，并且您的web.config已插入正确的canvas-url / canvas-page。（在您的情况下，为了测试，“http://localhost/”/“http://apps.facebook.com/yourappname”）

最近我读了一篇文章，说你不能使用Facebook.Mvc类，因为它们提供了示例代码。见1. Answer on this link

Answer 2

试试此代码

public ActionResult Index()
        {
            var url = "http://www.facebook.com/v2.2/dialog/oauth/?scope=user_friends,read_friendlists,publish_actions,read_stream,read_insights,manage_pages,user_checkins,user_photos,read_mailbox,manage_notifications,read_page_mailboxes,email,user_videos,user_groups,offline_access,publish_actions,manage_pages&client_id=" + ConfigurationManager.AppSettings["ClientId"] + "&redirect_uri=" + ConfigurationManager.AppSettings["RedirectUrl"] + "&response_type=code";

            return Redirect(url);
        }

回拨网址

    public string AddFacebookAccount(string code)
    {
        string ret = string.Empty;
        string client_id = ConfigurationManager.AppSettings["ClientId"];
        string redirect_uri = ConfigurationManager.AppSettings["RedirectUrl"];
        string client_secret = ConfigurationManager.AppSettings["ClientSecretKey"];
        long friendscount = 0;

                fbaccess_token = (JsonObject)fb.Get("/oauth/access_token", parameters);

            }

            string accessToken = fbaccess_token["access_token"].ToString();
            Session["AccessToken"] = accessToken;

                    friendscount = Convert.ToInt16(friends["summary"]["total_count"].ToString());

                catch (Exception ex)
                {
                    Console.Write(ex.Message);
                }

            }
            //return new JavaScriptSerializer().Serialize(ret);
            return ret;
