Laravel 5.5 覆盖供应商类

Laravel 5.5 Override vendor class

提问by Kiksy

I'm trying to override (not extend) a vendor class. So whenever the vendor class gets called (within the vendor code), I want it to call my custom class.

我正在尝试覆盖（而不是扩展）供应商类。因此，无论何时调用供应商类（在供应商代码中），我都希望它调用我的自定义类。

It looks like I need to alias the class in my App/Providers/AppServiceProvider

看起来我需要在我的类中别名 App/Providers/AppServiceProvider

I've tried this:

我试过这个：

$loader = \Illuminate\Foundation\AliasLoader::getInstance();
$loader->alias('Vendor\VendorName\Class', 'App\Vendor\MyCustomClass');

But this doesn't do anything.

但这没有任何作用。

I can get my class registered fine:

我可以很好地注册我的课程：

 $this->app->register(
       'App\Vendor\MyCustomClass'
   );

But this then fails as the constructor relys on other variables not available at that point. I literally just need the app to override any call to Vendor\VendorName\Classwith App\Vendor\MyCustomClass

但这会失败，因为构造函数依赖于当时不可用的其他变量。我真的只需要该应用程序来覆盖对Vendor\VendorName\Classwith 的任何调用App\Vendor\MyCustomClass

So the solution was create a new ServiceProvider

所以解决方案是创建一个新的 ServiceProvider

php artisan make:provider MyServiceProvider

Which extended the Vendor service provider (found within config/app.php). Within that ServiceProvider, add my alias within the overridden Registermethod

它扩展了供应商服务提供者（在 config/app.php 中找到）。在该 ServiceProvider 中，在重写的Register方法中添加我的别名

 $loader->alias('Vendor\VendorName\Class', 'App\Vendor\MyCustomClass');
