有點卡住這是怎麼發生的，但我目前已啓用Google和Facebook外部登錄到我乾淨的MVC5項目。當你登錄使用外部登錄，但是當你試圖將一個帳戶從Manage/ManageLogins在任的2個按鈕的鏈接，然後點擊我得到這個錯誤VS2015 MVC5默認模板，管理外部登錄錯誤？
一切正常
沒有修改任何代碼除了加入谷歌/ Facebook的整合繼ASP.NET
教程從ManageController默認代碼，如果有人有興趣
//
// GET: /Manage/ManageLogins
public async Task<ActionResult> ManageLogins(ManageMessageId? message)
{
ViewBag.StatusMessage =
message == ManageMessageId.RemoveLoginSuccess ? "The external login was removed."
: message == ManageMessageId.Error ? "An error has occurred."
: "";
var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
if (user == null)
{
return View("Error");
}
var userLogins = await UserManager.GetLoginsAsync(User.Identity.GetUserId());
var otherLogins = AuthenticationManager.GetExternalAuthenticationTypes().Where(auth => userLogins.All(ul => auth.AuthenticationType != ul.LoginProvider)).ToList();
ViewBag.ShowRemoveButton = user.PasswordHash != null || userLogins.Count > 1;
return View(new ManageLoginsViewModel
{
CurrentLogins = userLogins,
OtherLogins = otherLogins
});
}
//
// POST: /Manage/LinkLogin
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult LinkLogin(string provider)
{
// Request a redirect to the external login provider to link a login for the current user
return new AccountController.ChallengeResult(provider, Url.Action("LinkLoginCallback", "Manage"), User.Identity.GetUserId());
}
//
// GET: /Manage/LinkLoginCallback
public async Task<ActionResult> LinkLoginCallback()
{
var loginInfo = await AuthenticationManager.GetExternalLoginInfoAsync(XsrfKey, User.Identity.GetUserId());
if (loginInfo == null)
{
return RedirectToAction("ManageLogins", new { Message = ManageMessageId.Error });
}
var result = await UserManager.AddLoginAsync(User.Identity.GetUserId(), loginInfo.Login);
return result.Succeeded ? RedirectToAction("ManageLogins") : RedirectToAction("ManageLogins", new { Message = ManageMessageId.Error });
}
