api - .net core - 如何在 AuthorizationHandler 上返回 403？

Question

我实现了我的自定义 AuthorizationHandler。
对此，我检查用户可以解决并处于事件状态。

如果用户不活跃，那么我想返回 403 状态。

protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, ValidUserRequirement requirement)
{
    var userId = context.User.FindFirstValue( ClaimTypes.NameIdentifier );

    if (userId != null)
    {
        var user = await _userManager.GetUserAsync(userId);

        if (user != null)
        {
            _httpContextAccessor.HttpContext.AddCurrentUser(user);

            if (user.Active)
            {
                context.Succeed(requirement);
                return;
            }
            else
            {
                _log.LogWarning(string.Format("User ´{1}´ with id: ´{0} isn't active", userId, user.UserName), null);
            }
        }
        else
        {
            _log.LogWarning(string.Format("Can't find user with id: ´{0}´", userId), null);
        }
    } else
    {
        _log.LogWarning(string.Format("Can't get user id from token"), null);
    }

    context.Fail();

    var response = _httpContextAccessor.HttpContext.Response;
    response.StatusCode = 403;

}

但是我收到了 401。你能帮帮我吗？

你能在你的函数结束时检查一下吗？我在我的自定义中间件中使用它在某些情况下将状态代码重写为 401，但在您的场景中也应该有效

var filterContext = context.Resource as AuthorizationFilterContext;
var response = filterContext?.HttpContext.Response;
response?.OnStarting(async () =>
{
    filterContext.HttpContext.Response.StatusCode = 403;
//await response.Body.WriteAsync(message, 0, message.Length); only when you want to pass a message
});
