ASP.NET Core：如果通过IAuthorizationPolicyProvider获取

Question

AuthorizeFilter 添加 AuthorizationPolicy 的代码如下：services.AddMvc(o =>     {        var policy = new AuthorizationPolicyBuilder()             .RequireRole(ROLE_NAME)             .Build();         o.Filters.Add(new AuthorizeFilter(policy));     });请问如何通过 IAuthorizationPolicyProvider 接口获取上面添加的 AuthorizationPolicy ?

Answer 1

AuthorizeFilter 添加的 AuthorizationPolicy 是无法通过 IAuthorizationPolicyProvider 获取到的，需要在 services.AddAuthorization 中通过 AddPolicy 添加

services.AddAuthorization(options =>
{
    options.AddPolicy(POLICY_NAME, policy =>
    {
        policy.RequireAuthenticatedUser().RequireRole(ROLE_NAME);
    });
});
