我正在ASP.NET MVC 5中开发一个基本网站（使用visual studio 2013）。该网站将使用Facebook进行用户身份验证和检索初始个人资料数据。像堆栈流量登录与facebook ..access用户名，个人资料照片等..plz任何一个帮助我相关的样本
startup.auth.cs
FacebookAuthenticationOptions fbao = new FacebookAuthenticationOptions();
fbao.AppId = "****";
fbao.AppSecret = "*****";
fbao.Scope.Add("email");
fbao.Scope.Add("user_birthday");
fbao.Scope.Add("user_hometown");
fbao.SignInAsAuthenticationType = Microsoft.Owin.Security.AppBuilderSecurityExtensions.GetDefaultSignInAsAuthenticationType(app);
app.UseFacebookAuthentication(fbao);
帐户控制器＆gt;＆gt; Externallogincallback
// GET: /Account/ExternalLoginCallback
[AllowAnonymous]
public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
ClaimsIdentity fboa = await AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);
//var email = ext.Claims.First(x => x.Type.Contains("emailaddress")).Value;
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync();
if (loginInfo == null)
{
return RedirectToAction("Login");
}
// Sign in the user with this external login provider if the user already has a login
var result = await SignInManager.ExternalSignInAsync(loginInfo, isPersistent: false);
switch (result)
{
case SignInStatus.Success:
return RedirectToLocal(returnUrl);
case SignInStatus.LockedOut:
return View("Lockout");
case SignInStatus.RequiresVerification:
return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = false });
case SignInStatus.Failure:
default:
// If the user does not have an account, then prompt the user to create an account
ViewBag.ReturnUrl = returnUrl;
ViewBag.LoginProvider = loginInfo.Login.LoginProvider;
return View("ExternalLoginConfirmation", new ExternalLoginConfirmationViewModel { Email = loginInfo.Email });
}
}
帐户视图模型
public class ExternalLoginConfirmationViewModel
{
[Required]
[Display(Name = "Email")]
public string Email { get; set; }
public string UserName { get; set; }
}
