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。这是页面列表显示 0 的位置

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

以下是我尝试过的代码

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;


                    }

I have Finally managed to get the desired result using #Remodal.js

<head>
 <link rel="stylesheet" href="@Url.Content("~/Content/jquery.remodal.css")">
