Question

我为facebook墙贴设置了一个facebook应用，将其配置为指向我的localhost，并在facebook中创建了一个指向本地应用的标签。

一切正常，初始加载使我的页面正常，并且当我检查FacebookWebContext.Current.IsAuthenticated()时，用户已经过身份验证。

我的问题是，当我发回数据时，Facebook上下文丢失，FacebookWebContext.Current.IsAuthenticated()返回false。

我在.aspx页面检查过相同的代码;它运行良好，但同样的代码在mvc应用程序中不起作用。

我的代码

 <input  value="Facebook Wall Posting" onclick="FacebookWall()" type="button" />

<script>
 function fbAction()
           {
                var fbid=$('#txtFBID').val(); 
                var url = "http://www.facebook.com/dialog/friends/?id=" + fbid + "&app_id=244816449015123&redirect_uri=http://localhost:15995/Saloon/CustomerPost";
                location.href = url;
            }        
            function FacebookWall() {
                $.ajax({
            type: "POST",
            url: '@Url.Action("FacebookWall", "Saloon")',
        contentType: "application/json; charset=utf-8",
        //data: { FacebookId: $('#txtFBID').val() },
        dataType: "json",
        success: function() { }

    });
            } 
</script>

            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;

                StreamReader reader = new StreamReader(response.GetResponseStream());

                string vals = reader.ReadToEnd();

                foreach (string token in vals.Split('&'))

      tokens.Add(token.Substring(0, token.IndexOf("=")),
          token.Substring(token.IndexOf("=") + 1, token.Length -                                                   token.IndexOf("=") - 1));
                }
            }

            string access_token = tokens["access_token"];

            string fil = Server.MapPath("Images/2921-large-apple-icon-png-1.jp");
            var client = new FacebookClient(access_token);

            dynamic parameters = new ExpandoObject();
            parameters.message = "Check out this funny article";
            parameters.link = "http://www.natiska.com/article.html";
            parameters.picture = "http://www.natiska.com/dav.png";
            parameters.name = "Article Title";
            parameters.caption = "Caption for the link";

           client.Post("/me/feed", parameters);


        }
        return View();
         }
