Question

我有一个基础AsyncController

BaseController : AsyncController
{ 
    [Authorize("Admin")]
    public virtual async Task<ActionResult> SomeMethod()
    {
        //code
    }
}

如何正确继承并覆盖 SomeMethod ？

UserController : BaseController
{ 
    [Authorize("User")]
    public override Task<ActionResult> SomeMethod()
    {
        return base.SomeMethod()
    }
}

或

UserController : BaseController
{ 
    [Authorize("User")]
    public override async Task<ActionResult> SomeMethod()
    {
        return await base.SomeMethod()
    }
}

P.S。对不起我的英文

SomeMethod()在您的BaseController课程中定义。因此，子类应继承自BaseController而不是AsyncController。要覆盖该方法，只需在定义中添加virtual关键字即可。

BaseController : AsyncController
{ 
    [Authorize("Admin")]
    public virtual async Task<ActionResult> SomeMethod()
    {
        //code
    }
}

继承和覆盖

UserController : BaseController
{ 
    [Authorize("User")]
    public override Task<ActionResult> SomeMethod()
    {
        return base.SomeMethod()
    }
}

我也注意到Authorize属性中有些奇怪的东西。如果基本方法仅允许Admin，并且子方法仅允许User，那么您很可能最终无法从子类执行base方法。
