如何使用Laravel创建立面类? [英] How do I create a facade class with Laravel?

问题描述

使用Laravel创建立面模型类时遇到了一些问题.我已经关注了 http://laravel.com/docs/facades ，但我想我缺少了一些东西.

I'm having a little problem with creating a facade model class with Laravel. I have followed http://laravel.com/docs/facades but I guess I'm missing something.

我在app/models中创建了一个名为foo的文件夹.在那个文件夹中，我有两个文件.

I have created a folder in app/models called foo. In that folder I have two files.

第一个文件(Foo.php):

First file (Foo.php):

<?php
namespace Mynamespace;

class Foo {
    public function method() {

    }
}
?>

第二个文件(FooFacade.php):

Second file (FooFacade.php):

<?php
use Illuminate\Support\Facades\Facade;

class Foo extends Facade {
    protected static function getFacadeAccessor() { return 'foo'; }
}
?>

然后我将Foo => 'Mynamespace\Foo'添加到app/config/app.php中的aliases数组中，并运行composer update和composer dump-autoload.

Then I added Foo => 'Mynamespace\Foo' to the aliases array in app/config/app.php and ran composer update and composer dump-autoload.

现在，当我尝试运行Foo::method()时，我得到了Non-static method Mynamespace\Foo::method() should not be called statically.我在做什么错了?

Now when I try to run Foo::method() I get Non-static method Mynamespace\Foo::method() should not be called statically. What am I doing wrong?

推荐答案

步骤1

在app文件夹(app/facades)中创建一个名为facades的文件夹.

Step 1

Create a folder called facades in your app folder (app/facades).

将立面文件夹添加到您的作曲家自动加载中.

Add the facade folder to your composer autoload.

"autoload": {
    "classmap": [
        ...
        "app/facades"
    ]
},

步骤3

在该文件夹(FooFacade.php)中创建一个Facade文件并添加以下内容:

Step 3

Create a Facade file in that folder (FooFacade.php) and add this content:

<?php
use Illuminate\Support\Facades\Facade;

class MyClass extends Facade {
    protected static function getFacadeAccessor() { return 'MyClassAlias'; } // most likely you want MyClass here
}

步骤4

在app/models(MyClass.php)中创建模型.

Step 4

Create a model in app/models (MyClass.php).

<?php
namespace MyNamespace;

use Eloquent; // if you're extending Eloquent

class MyClass extends Eloquent {
    ...
}

步骤5

创建一个新的服务提供商(您可以在应用程序中创建一个名为serviceproviders的文件夹并将其添加到composer自动加载中)(app/models/MyClassServiceProvider.php).

Step 5

Create a new service provider (you can create a folder in app called serviceproviders and add it to composer autoload) (app/models/MyClassServiceProvider.php).

<?php
use Illuminate\Support\ServiceProvider;

class MyClassServiceProvider extends ServiceProvider {
    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register() {
        $this->app->bind('MyClassAlias', function(){
            return new MyNamespace\MyClass;
        });
    }
}

如果要使用其他外观，可以在此处添加新的绑定(如果需要，请不要忘记创建外观文件).

Here you can add new binding if you want another facade (don't forget to create a facade file if so).

将服务提供者添加到config/app.php中的providers阵列中.

Add the service provider to the providers array in config/app.php.

'providers' => array(
    ...
    'MyServiceProvider'
)

步骤7

运行composer dump，以便我们可以访问新类.

Step 7

Run composer dump so we can access our new classes.

您现在可以将MyClassAlias::method()作为外观访问.

You can now access MyClassAlias::method() as a facade.
