最近由于项目的需要对权限控制做了几个Demo，贴出来供大家拍砖！

首先创建一个 BaseController ，让所有的Controller继承自BaseController 。

<div class="container">
<div class="line number1 index0 alt2"><code class="csharp plain">[Authorize]</code></div>
<div class="line number2 index1 alt1"><code class="csharp keyword">public</code> <code class="csharp keyword">class</code> <code class="csharp plain">BaseController : Controller</code></div>
<div class="line number3 index2 alt2"><code class="csharp plain">{</code></div>
<div class="line number4 index3 alt1"></div>
<div class="line number5 index4 alt2"><code class="csharp plain">}</code></div>
<div class="line number5 index4 alt2">

<div class="container"> <div class="line number1 index0 alt2"><code class="csharp spaces"> </code><code class="csharp plain">[AllowAnonymous]</code></div> <div class="line number2 index1 alt1"><code
