通过OAuth登录用户后，我无法获得用户ID的MVC [英] MVC Simplemembership I cannot get the userID after logging a user in via OAuth

问题描述

所以我正在通过MVC 4 simplemembership oAuth提供程序实现Facebook登录.

So I am in the process of implementing a Facebook login via MVC 4 simplemembership oAuth provider.

注册和登录用户效果很好.但是，在使用oAth登录用户后，我无法获取经过身份验证的用户的UserId.我可以看到MemberId_oauth表中存在UserId，它与UserProfile表中的UserId相关.

Registering and signing in the user has worked well. However after signing in a user using oAth, I am unable to get the UserId of the authenticated user. I can see that the UserId exists in the membership_oauth table and it relates to the UserId in the UserProfile table.

通常，我会使用WebSecurity.CurrentUserId来获取它，但似乎没有使用OAuthWebSecurity时获取此方法的方法.当我尝试WebSecurity.CurrentUserId时，我得到该对象的实例尚未实例化"，错误.

Normally I would fetch it using WebSecurity.CurrentUserId but there does not seem to be a method for getting this when using OAuthWebSecurity. When I try, WebSecurity.CurrentUserId I get "an instance of the object has not been instantiated", error.

有人知道如何获取此信息吗?

Does anybody know how to get this information?

非常感谢！

推荐答案

我假设您正在尝试在控制器中获取userID.您是否尝试过:

I assume you're trying to get the userID in in a controller. Have you tried:

int currentUserId = (int) Membership.GetUser().ProviderUserKey;

我无法告诉您这是否适用于Facebook，但适用于Google Auth.对我来说.

I can't tell you if this works with Facebook or not, but it works with Google Auth. for me.

如果您使用的不是AccountController，则还应该在控制器类的顶部添加 [InitializeSimpleMembership] .

You should also add [InitializeSimpleMembership] on top of controller class if you use another controller than AccountController.

检查此内容:在新的MVC4应用程序中获取UserId(int)

检查此方法

Check this method int GetUserIdFromOAuth(string provider, string providerUserId) and try something like:

SimpleMembershipProvider provider = (SimpleMembershipProvider) Membership.Provider;
int id = provider.GetUserIdFromOAuth("you_know_the_provider", "you_can_get_the_provider_user_id")

抱怨与您的问题相反:他想要ProviderUserKey，但一直获取UserID.

is complaining about the opposite of your problem: he wants the ProviderUserKey but keeps getting the UserID instead.
