我正在使用Claims在ASP.NET Core中开发自己的项目,并参考了以下文章:http://blog.geveo.com/Claim-based-authorization-ASP-core

在步骤05中,我们从Permissions的位置很难理解,因为它在任何地方都没有定义。有什么想法吗?

services.AddAuthorization(options =>
{
    options.AddPolicy(PolicyTypes.Teams.Manage, policy => {
        policy.RequireClaim(CustomClaimTypes.Permission, Permissions.Teams.Manage);
    });
    options.AddPolicy(PolicyTypes.Teams.AddRemove, policy => {
        policy.RequireClaim(CustomClaimTypes.Permission, Permissions.Teams.AddRemove);
    });
    options.AddPolicy(PolicyTypes.Users.Manage, policy => {
        policy.RequireClaim(CustomClaimTypes.Permission, Permissions.Users.Add);
    });
    options.AddPolicy(PolicyTypes.Users.EditRole, policy => {
        policy.RequireClaim(CustomClaimTypes.Permission, Permissions.Users.EditRole);
    });
}

该博客文章的第2步缺少一个同时包装UsersTeams类的类。它应该看起来像这样:

public static class Permissions
{
    public static class Users
    {
        public const string Add = "users.add";
        public const string Edit = "users.edit";
        public const string EditRole = "users.edit.role";
    }

    public static class Teams
    {
        public const string AddRemove = "teams.addremove";
        public const string EditManagers = "teams.edit.managers";
        public const string Delete = "teams.delete";
    }
}

最后,这只是定义了在整个应用程序中使用的通用值,以标识各种权限。您也可以只传递一些字符串,但是由于不需要记住魔术字符串,因此集中定义它们可以使使用更加容易。
