Yii2：如何在控制台命令中使用命名参数？ [英] Yii2: How do you use named parameters in console commands?

问题描述

如何编写控制台命令 yii controller / action --param1 = something --param2 = anything 并在操作中检索这些命名参数？

How can I write the console command yii controller/action --param1=something --param2=anything and retrieve those named parameters in the action?

推荐答案

我发现文档并没有说如何，而是像我预期的那样调用它的命名参数，它被称为选项： http://www.yiiframework.com/doc -2.0 / guide-tutorial-console.html＃create-command

I found out that the documentation does say how to, but instead of calling it "named parameters" as I expected it to, it is called options: http://www.yiiframework.com/doc-2.0/guide-tutorial-console.html#create-command

文档并不完整。下面是一个例子：

The docs is not quite complete though. So here is an example:

1. 将参数作为属性添加到控制器：

class CustomerController extends Controller {
    public $param1;
    public $param2;
    ...

1. 选项方法到控制器：

1. You add the options method to the controller:

    public function options($actionID) {
        return array_merge(parent::options($actionID), ['param1', 'param2']);
    }

$ actionID parent :: options（$ actionID）用于包含任何现有的选项。

$actionID must be specified, and parent::options($actionID) is used to include any existing options.

1. 现在，您可以使用 $ this-> param1 和 $ this- ; param2 ，例如：

1. You can now access the parameters within your action with $this->param1 and $this->param2, eg.:

    public function actionSomething() {
        doAnything($this->param1, $this->param2);
    }

可以组合非命名和命名参数。

It's okay to combine non-named and named parameters. The named ones just need to be specified last.

如果你指定一个没有值的参数（例如 - param1 而不是 - param1 = 500 ）的值 $ this-> param1 将为布尔 true 。如果没有指定，则 NULL 。

Also lacking from the docs is the fact that if you specify a parameter without a value (eg. --param1 instead of --param1=500) the value of $this->param1 will be boolean true. If not specified at all the value will be NULL.
