Yii2中的components的使用

1.common下创建components文件夹

2.创建类文件 Name.php

<?php
namespace common\components;
use yii\base\Component;

class QCC extends Component
{
    public $accessKeyId;
    public $accessKeySecret;
    public $endPoint;
    public $internalEndPoint;
    function getName()
    {
        return 'zhangsan';
    }
}

3.在main-local.php中加入

'name' => [
            'class' => QCC::className(),
            'accessKeyId' => 'LTAImxVilbdcFjgz',
            'accessKeySecret' => 'fROYKJij9Y80yZIWCAWmoWkcS2i5zc',
            'isCName' => false,
            'securityToken' => null,
            'defaultBucket' => 'test-order-file',
        ],

4.控制器调用

$qcc = Yii::$app->get('name');
$qcc->getName();
