OAuthWebSecurity创建帐户 - 它是如何工作的？

Question

我很困惑并关注以下行,因为看起来OAuthWebSecurity的API有自己的身份验证存储.

        // If the current user is logged in add the new account
        OAuthWebSecurity.CreateOrUpdateAccount(result.Provider, result.ProviderUserId, User.Identity.Name);

如果我正确阅读上述内容,似乎表明API在本地保存了关系.

请告诉我情况并非如此,并解释它到底是做什么的？我需要我的Web应用程序尽可能无状态,我不能让API存储像这样的本地值.

它使用SimpleMembershipProviderASP.NET MVC 4中的默认提供程序来创建或更新公共提供程序用户标识与本地用户之间的关联.基本上它会在webpages_OAuthMembership表格中添加一条记录.

这WebSecurity.CreateOrUpdateOAuthAccount是被调用的相应代码:

public override void CreateOrUpdateOAuthAccount(string provider, string providerUserId, string userName)
{
    this.VerifyInitialized();
    if (userName.IsEmpty())
    {
        throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
    }
    int userId = this.GetUserId(userName);
    if (userId == -1)
    {
        throw new MembershipCreateUserException(MembershipCreateStatus.InvalidUserName);
    }
    int userIdFromOAuth = this.GetUserIdFromOAuth(provider, providerUserId);
    using (IDatabase database = this.ConnectToDatabase())
    {
        if (userIdFromOAuth == -1)
        {
            if (database.Execute("INSERT INTO [" + OAuthMembershipTableName + "] (Provider, ProviderUserId, UserId) VALUES (@0, @1, @2)", new object[] { provider, providerUserId, userId }) != 1)
            {
                throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
            }
        }
        else if (database.Execute("UPDATE [" + OAuthMembershipTableName + "] SET UserId = @2 WHERE UPPER(Provider)=@0 AND UPPER(ProviderUserId)=@1", new object[] { provider, providerUserId, userId }) != 1)
        {
            throw new MembershipCreateUserException(MembershipCreateStatus.ProviderError);
        }
    }
}
