User.Identity.GetUserId（）&& User.IsInRole（“角色名称”）不起作用

Question

我正在尝试自定义ASP Identity 2.0以与Guid Key一起使用。 我可以正常登录，但是在尝试获取用户数据时遇到了一些问题。

这些都不起作用：

User.Identity.GetUserId() [始终以空字符串形式返回]

User.IsInRole("rolename") [总是返回false]

填充User.Identity.Name。

我的登录处理程序

public class CommandHandler : IRequestHandler<ViewModel, Result>
{
    private readonly GuidUserManager _manager;

    public CommandHandler(GuidUserManager manager)
    {
        _manager = manager;
    }

    public Result Handle(ViewModel criteria)
    {
        // Verify if a user exists with the provided identity information
        var user = _manager.Find(criteria.UserName, criteria.Password);

        // If a user was found
        if (user == null)
            return Result.Fail("Invalid username or password.");

        // Clear any lingering authencation data
        FormsAuthentication.SignOut();

        // Write the authentication cookie
        FormsAuthentication.SetAuthCookie(user.UserName, criteria.RememberMe);

        return Result.Ok();
    }
}

Answer 1

您需要在AccountController中使用此代码

public GuidUserManager UserManager
{
    get
    {
        return _userManager ?? HttpContext.GetOwinContext().GetUserManager<GuidUserManager>();
    }
    private set
    {
        _userManager = value;
    }
}

Answer 2

FormsAuthentication是您的问题。 您的web.config可能包含与MembershipRoleProvider相关的条目-与User.IsInRole 。 删除所有与FormsAuthentication相关的代码/配置，以解决您的问题。
