Laravel 5.7覆盖供应商类别并扩展旧的类别 [英] Laravel 5.7 Override vendor class and extend old one

问题描述

所以解决方案是创建一个新的ServiceProvider.

So the solution was to create a new ServiceProvider.

此解决方案适用于覆盖

php artisan make:provider MyServiceProvider

扩展了供应商服务提供商(位于config/app.php中).在该ServiceProvider中，将我的别名添加到覆盖的 register 方法

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

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

现在，如何扩展覆盖的类?我尝试过:

Now, how do I extend the overridden class? I tried this:

$loader->alias('ClassParent', 'Vendor\VendorName\Class');
$loader->alias('Vendor\VendorName\Class', 'App\Vendor\MyCustomClass');
...
class MyCustomClass extends ClassParent {} // not working

推荐答案

您需要做的第一件事就是扩展Vendor类:

First thing you need to do is extend the Vendor class:

class MyCustomClass extends Vendor\VendorName\Class {}

现在，此类具有Vendor类的属性和方法以及您添加的属性和方法.

Now, this class has the properties and methods of the Vendor class and the properties and methods you've added.

然后，您的自定义类可以成为别名:

Then, your custom class can become an alias:

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