问题描述

[AllowAnonymous]
public ActionResult Facebook()
{
    var fb = new FacebookClient();
    var loginUrl = fb.GetLoginUrl(new
    {
        client_id = "xxxxxx",
        client_secret = "xxxxx",
        redirect_uri = RedirectUri.AbsoluteUri,
        response_type = "code",
        scope = "email"
    });

    return Redirect(loginUrl.AbsoluteUri);
}
public ActionResult FacebookCallback(string code)
{
    var fb = new FacebookClient();
    dynamic result = fb.Post("oauth/access_token", new
    {
        client_id = "xxxxxx",
        client_secret = "xxxx",
        redirect_uri = RedirectUri.AbsoluteUri,
        code = code
    });

    var accessToken = result.access_token;

    // Store the access token in the session for farther use
    Session["AccessToken"] = accessToken;

    // update the facebook client with the access token so
    // we can make requests on behalf of the user
    fb.AccessToken = accessToken;

    // Get the user's information, like email, first name, middle name etc
    dynamic me = fb.Get("me?fields=first_name,middle_name,last_name,id,email");
    string email = me.email;
    string firstname = me.first_name;
    string middlename = me.middle_name;
    string lastname = me.last_name;
    if (ModelState.IsValid)
    {
        User _user = new User();
        _user.FullName = firstname;
        _user.Email = email;
        _user.PhoneNo = "";
        // _user.Password = model.Security.Password;
        //_user.RetypePassword = model.Security.RetypePassword;
        //_user.CityId = model.Security.CityId;
        //_user.IsUpdate = model.Security.IsUpdate;
        _user.StatusId = (byte)Utilities.Status.Active;
        _user.EmailConfirmed = true;
        _user.Image = "/images/business.png";
        _user.CreatedDate = DateTime.Now;
        _user.ModifiedDate = DateTime.Now;
        _user.CreatedBy = 1;
        var userObj = seuritybll.Insert(_user);
        Session["User"] = me;
        Session["UserName"] = firstname;
        return RedirectToAction("Index", "Home");
        //return RedirectToAction("RegistrationSuccessfull");
    }
    // Set the auth cookie
    FormsAuthentication.SetAuthCookie(email, false);
    return RedirectToAction("Index", "Home");
}

我的尝试：



我在asp.net mvc网站上使用上面的代码登录facebook

但是使用这个代码我只能从我的facebook帐户登录。当我从其他帐户登录时它给出了错误就像你的应用程序不是在开发者选项中创建我跟着这个链接

你可以帮我吗
