2.0高级版怎么整合Smarty [ 2.0 版本 ]

• composer.json里require加上一项"yiisoft/yii2-smarty": "*"，然后通过composer安装

• frontend/config/main.php里components加上一项view

'view' => [
    'renderers' => [
        'tpl' => [ // smarty模板的后缀名
            'class' => 'yii\smarty\ViewRenderer',
            'cachePath' => '@runtime/Smarty/cache',
        ],
    ],
],

• 在controller里通过renderFile来显示smarty模板页面

public function actionIndex()
{
    $params = [
       'domainName' => 'yiichina.com', // smarty模板中用到的变量$domainName
    ];
    return $this->renderFile('@static/views/index.tpl', $params);
}
