您可以使用授权策略 在Startup.cs

    services.AddAuthorization(options =>
    {
        options.AddPolicy("admin", policy => policy.RequireRole("SuperAdmin","Admin"));
        options.AddPolicy("teacher", policy => policy.RequireRole("SuperAdmin", "Admin", "Teacher"));
    });

在控制器文件中:

 [Authorize(Policy = "teacher")]
 [HttpGet("stats/{id}")]
 public async Task<IActionResult> getStudentStats(int id)
 { ... }

“教师”政策接受3个角色。

另一种选择是使用一个单独的授权过滤器，但删除内部报价。

[Authorize(Roles="members,admin")]

使用AspNetCore 2。X，你必须走不同的路:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AuthorizeRoleAttribute : AuthorizeAttribute
{
    public AuthorizeRoleAttribute(params YourEnum[] roles)
    {
        Policy = string.Join(",", roles.Select(r => r.GetDescription()));
    }
}

就像这样使用它:

[Authorize(YourEnum.Role1, YourEnum.Role2)]

一个可能的简化是子类AuthorizeAttribute:

public class RolesAttribute : AuthorizeAttribute
{
    public RolesAttribute(params string[] roles)
    {
        Roles = String.Join(",", roles);
    }
}

用法:

[Roles("members", "admin")]

从语义上看，它和Jim Schmehil的答案是一样的。

Intent promptInstall = new Intent(android.content.Intent.ACTION_VIEW);
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
promptInstall.setDataAndType(Uri.parse("http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk"), "application/vnd.android.package-archive" );

startActivity(promptInstall);

您可以使用授权策略 在Startup.cs

    services.AddAuthorization(options =>
    {
        options.AddPolicy("admin", policy => policy.RequireRole("SuperAdmin","Admin"));
        options.AddPolicy("teacher", policy => policy.RequireRole("SuperAdmin", "Admin", "Teacher"));
    });

在控制器文件中:

 [Authorize(Policy = "teacher")]
 [HttpGet("stats/{id}")]
 public async Task<IActionResult> getStudentStats(int id)
 { ... }

“教师”政策接受3个角色。
