Laravel 实现 Facades 功能
使用过Laravel的同学都知道Facades 的强大，下面就让我们一起创建一个Facades 实例。如有不正确的地方，还请不吝赐教。
1. 实现Laravel的自动加载功能
首先建立目录app/lib/Myapp，然后添加目录到composer.json中
<span style="color: #008080">1</span> "autoload":<span style="color: #000000"> { </span><span style="color: #008080">2</span> "psr-0":<span style="color: #000000">{</span><span style="color: #008080">3</span> "Myapp":"app/lib"<span style="color: #008080">4</span> <span style="color: #000000"> }</span><span style="color: #008080">5</span> }
2. 实现功能类
实现能能类 app/lib/Myapp/Test.php
<span style="color: #008080"> 1</span> <?<span style="color: #000000">php</span><span style="color: #008080"> 2</span> <span style="color: #008000">/*</span><span style="color: #008000">*</span><span style="color: #008080"> 3</span> <span style="color: #008000"> * @author brudeke</span><span style="color: #008080"> 4</span> <span style="color: #008000">*/</span><span style="color: #008080"> 5</span> <span style="color: #000000">namespace Myapp;</span><span style="color: #008080"> 6</span> <span style="color: #0000ff">class</span><span style="color: #000000"> Test{</span><span style="color: #008080"> 7</span> <span style="color: #0000ff">public</span> <span style="color: #0000ff">function</span> <span style="color: #0000ff">do</span><span style="color: #000000">(){</span><span style="color: #008080"> 8</span> <span style="color: #0000ff">echo</span> 'this is a class'<span style="color: #000000">;</span><span style="color: #008080"> 9</span> <span style="color: #000000"> }</span><span style="color: #008080">10</span> }
3. 实现ServiceProvider
实现app/lib/Myapp/TestServiceProvider.php ，该类主要是将功能类添加到Ioc容器:
<?<span style="color: #000000">php</span><span style="color: #008000">/*</span><span style="color: #008000">* * @author brudeke </span><span style="color: #008000">*/</span><span style="color: #000000">namespace Myapp;</span><span style="color: #0000ff">use</span><span style="color: #000000"> Illuminate\Support\ServiceProvider;</span><span style="color: #0000ff">class</span> TestServiceProvider <span style="color: #0000ff">extends</span><span style="color: #000000"> ServiceProvider{ </span><span style="color: #0000ff">public</span> <span style="color: #0000ff">function</span><span style="color: #000000"> register() { </span><span style="color: #800080">$this</span>->app['test'] = <span style="color: #800080">$this</span>->app-><span style="color: #000000">share( </span><span style="color: #0000ff">function</span> (<span style="color: #800080">$app</span><span style="color: #000000">) { </span><span style="color: #0000ff">return</span> <span style="color: #0000ff">new</span><span style="color: #000000"> \Myapp\Test(); }); }}</span>
4. 实现Facade 实例
实现app/lib/Myapp/Facades/TestFacades.php， 该类的主要美化，实现成员函数类似静态方法的调用形式
<span style="color: #008080"> 1</span> <?<span style="color: #000000">php</span><span style="color: #008080"> 2</span> <span style="color: #008000">/*</span><span style="color: #008000">*</span><span style="color: #008080"> 3</span> <span style="color: #008000"> * @author brud<em style="color:transparent">本文来源[email protected]搞@^&代*@码)网9</em><strong>搞代gaodaima码</strong>eke</span><span style="color: #008080"> 4</span> <span style="color: #008000">*/</span><span style="color: #008080"> 5</span> <span style="color: #000000">namespace Myapp\Facades;</span><span style="color: #008080"> 6</span> <span style="color: #008080"> 7</span> <span style="color: #0000ff">use</span><span style="color: #000000"> Illuminate\Support\Facades\Facade;</span><span style="color: #008080"> 8</span> <span style="color: #008080"> 9</span> <span style="color: #0000ff">class</span> TestFacades <span style="color: #0000ff">extends</span><span style="color: #000000"> Facade{</span><span style="color: #008080">10</span> <span style="color: #0000ff">protected</span> <span style="color: #0000ff">static</span> <span style="color: #0000ff">function</span><span style="color: #000000"> getFacadeAccessor()</span><span style="color: #008080">11</span> <span style="color: #000000"> {</span><span style="color: #008080">12</span> <span style="color: #0000ff">return</span> 'test'<span style="color: #000000">;</span><span style="color: #008080">13</span> <span style="color: #000000"> }</span><span style="color: #008080">14</span> }
5. 加载ServiceProvider
在app/config/app.php 中的providers中添加如下配置：
<span style="color: #008080">1</span> 'providers' => <span style="color: #0000ff">array</span><span style="color: #000000">( </span><span style="color: #008080">2</span> 'Myapp\TestServiceProvider'<span style="color: #008080">3</span> ),
在app/config/app.php 中的aliases中添加别名：
<span style="color: #008080">1</span> 'aliases' => <span style="color: #0000ff">array</span><span style="color: #000000">(</span><span style="color: #008080">2</span> 'TestClass' => 'Myapp\Facades\TestFacades',<span style="color: #008080">3</span> ),
接下来就可以在项目中以TestClass::do()的形式使用该功能类了。
