如何在控制台/ shell中加载组件 [英] How to load a component in console/shell

问题描述

在CakePHP中，如何在shell中加载组件？

In CakePHP, how do I load a component in a shell?

要在控制器中使用组件，您需要在属性$组件。这对我的壳不起作用。

To use a component in a controller, you include an array of components in a property called $components. That doesn't work for my Shell. Neither does the "on-the-fly" loading suggested in the documentation.

class MakePdfsShell extends Shell {
    public $components = array('Document'); // <- this doesn't work
    public function main()
    {
        $this->Document = $this->Components->load('Document'); // <- this doesnt work either
        $this->Document->generate(); // <- this is what I want to do
    }
    ...

推荐答案

如果你试图从shell访问自定义XyzComponent，那么你可能有通常有用的功能。通常有用功能（也可从shell访问）的正确位置在 / Lib / 。

If you are trying to access a custom XyzComponent from a shell, then you probably have commonly-useful functionality there. The right place for commonly-useful functionality (that is also accessible from shells) is in /Lib/.

您可以将旧的XyzComponent类从 /Controller/Component/XyzComponent.php 移动到 /Lib/Xyz/Xyz.php 。 （您应该重命名您的类以删除Component后缀，例如XyzComponent变为Xyz。）

You can just move your old XyzComponent class from /Controller/Component/XyzComponent.php to /Lib/Xyz/Xyz.php. (You should rename your class to remove the "Component" suffix, e.g., "XyzComponent" becomes "Xyz".)

要访问新位置，从 class :: $ components 数组中删除'Xyz'。在控制器文件的顶部，添加

To access the new location, in your controller, remove 'Xyz' from your class::$components array. At the top of your controller file, add

App::uses('Xyz', 'Xyz'); // that's ('ClassName', 'folder_under_/Lib/')

现在你只需要实例化班上。在你的方法中，你可以做 $ this-> Xyz = new Xyz（）; 现在你使用相同的代码，但也可以从Shell访问。

Now you just need to instantiate the class. In your method you can do $this->Xyz = new Xyz(); Now you're using the same code, but it can also be accessed from your Shell.
