Question

我正在开发一个使用ASP.NET Boilerplate构建的项目。我使用的模板是带有Angular的.NET Core，包括Module Zero。启用多方租用。

我目前正在处理的任务是允许主持人管理员查看来自每个租户的Admin角色的用户。我在租户列表的弹出菜单（Actions列）中添加了一个新菜单项。它调用API方法并传入tenantId。

API代码如下所示（遵循Boilerplate代码模式）：

if (tenantId != null)
{
    UnitOfWorkManager.Current.SetTenantId(tenantId.Value);

    adminRole = await _roleManager.GetRoleByNameAsync("admin");
}

if (tenantId != null && adminRole != null)
{
    users = users.Where(u => u.Roles.Any(r => r.RoleId == adminRole.Id));
}

var totalCount = await AsyncQueryableExecuter.CountAsync(users);

users = ApplySorting(users, input);

users = ApplyPaging(users, input);

在申请表中，我有很多租户。有些人有自己的数据库，有些人没有。当租户拥有自己独立的数据库时，上面的代码按预期工作，而租户没有，我得到一条错误消息：

未授予所需权限。必须至少授予其中一个权限：用户

在日志文件中，我有以下例外：

问题在于，为什么相同的代码适用于拥有自己的数据库的租户，但是对于其他人我得到了例外？我需要做什么，以便无论租户如何设置，我都可以使用此代码？

欢迎所有建议。

AuthorizationInterceptor似乎不必要地拦截了ApplySorting方法。

您可以使用[AbpAllowAnonymous]属性安全地覆盖该方法：

[AbpAllowAnonymous]
protected override IQueryable<User> ApplySorting(IQueryable<User> query, UserGetAllInput input)
{
    return base.ApplySorting(query, input);
}

如何从主机列出具有特定角色的租户用户？
