【问题描述】：

我正在尝试使用 c# MVC 在 Facebook 中获取页面数据。即使我授予 manage_pages 权限（范围），当我运行我的代码时它也不会显示任何页面。这是 pagelist 显示 0 的地方

string Accounts = "/me/accounts";
JSONObject pageData = api.Get(Accounts);
var data = pageData.Dictionary["data"];
List<JSONObject> pageList = data.Array.ToList<JSONObject>();
ViewBag.pageList = pageList;

下面是我试过的代码

public ActionResult returnfromfb()
    
        string app_id = "AppID";
        string app_secret = "AppSecret";
        string scope = "manage_pages,publish_stream,status_update,user_about_me,user_hometown,user_location,email,offline_access";

        string code = Request.QueryString["code"];
        if (code == null)
        
            Response.Redirect(string.Format("https://graph.facebook.com/oauth/authorize?client_id=0&redirect_uri=1&scope=2",
                app_id, Request.Url.AbsoluteUri, scope));

        

        string AccessToken = "";
        try
        
            if (code != null)
            
                string str = string.Format("https://graph.facebook.com/oauth/access_token?client_id=0&redirect_uri=1&scope=2&code=3&client_secret=4",
                app_id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);

                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(str);
                req.Method = "POST";
                req.ContentType = "application/x-www-form-urlencoded";
                byte[] Param = Request.BinaryRead(System.Web.HttpContext.Current.Request.ContentLength);
                string strRequest = System.Text.Encoding.ASCII.GetString(Param);

                req.ContentLength = strRequest.Length;

                StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
                streamOut.Write(strRequest);
                streamOut.Close();
                StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
                string strResponse = streamIn.ReadToEnd();
                if (strResponse.Contains("&expires"))
                    strResponse = strResponse.Substring(0, strResponse.IndexOf("&expires"));
                AccessToken = strResponse.Replace("access_token=", "");
                streamIn.Close();
            

            Facebook.FacebookAPI api = new Facebook.FacebookAPI(AccessToken);
            string requestEmail = "/me";
            JSONObject fbemail = api.Get(requestEmail);
            try
            
                ViewBag.Email = fbemail.Dictionary["email"].String;
            
            catch (Exception ex)
            
                //errorLog.setError(ex, "LoginController.SaveFacebookData");
            

            string Accounts = "/me/accounts";
            JSONObject pageData = api.Get(Accounts);
            var data = pageData.Dictionary["data"];
            List<JSONObject> pageList = data.Array.ToList<JSONObject>();
            ViewBag.pageList = pageList;
            foreach (var page in pageList)
            

                try
                
                   var id = page.Dictionary["id"].String;
                    string request = id;
                    JSONObject fbobject = api.Get(request);
                    try
                    
                        ViewBag.BusinessName = fbobject.Dictionary["name"].String;
                        ViewBag.Address = fbobject.Dictionary["location"].ToDisplayableString();
                        ViewBag.PhoneNumber = fbobject.Dictionary["phone"].String;


                    
                    catch (Exception ex)
                    
                        //errorLog.setError(ex, "LoginController.SaveFacebookData");
                    
                
                catch (Exception ex)
                
                    //errorLog.setError(ex, "LoginController.SaveFacebookData");
                
            

【问题讨论】：

你们一直从哪里复制代码？ status_update 和 offline_access 已被弃用多年。

那个？ > facebooktoolkit.codeplex.com - 你知道，它是 2010 年的。

@luschn- 事情是它在我的 Facebook 帐户上运行良好，就像我在不同的帐户上尝试它一样，即使它们存在，它也不会显示该帐户的页面。
