Yii2：如何使用 301 重定向旧 URL？

Question

I have some URLs from the old version of my site that I want to redirect to their new ones in Yii2 due to SEO purposes, eg. /about-us.php to /about . How do I do that?

I can't use .htaccess , and I can't use urlManager rules because HTTP response status 301 needs to be set.

I tried the following in a bootstrap class but even though the code executes I still just get a 404 when going to the old URL:

if (preg_match("|^/about.php|", $_SERVER['REQUEST_URI'])) {
    Yii::$app->response->redirect('/about', 301)->send();
    return;
}

Answer 1

there is a cleaner and easier way to do it:

class MyController extends Controller
{
    public function beforeAction($action)
    {
        if (in_array($action->id, ['about-us'])) {
            Yii::$app->response->redirect(Url::to(['about']), 301);
            Yii::$app->end();
        }
        return parent::beforeAction($action);
    }
}

Hope that will be helpful!

Just found the answer myself. My bootstrap attempt was not so bad, I just needed to add Yii::$app->end() :

if (preg_match("|^/about-us.php|", $_SERVER['REQUEST_URI'])) {
    Yii::$app->response->redirect('/about', 301)->send();
    Yii::$app->end();
    return;
}

Here is also another variant.

Yii 1.1

public function actionOldPage()
{
    Yii::app()->request->redirect('redirect/to/this', true, 301);
}

First I tried UrlManager in config/main.php

'oldPage'=>'newPage'

but it's redirect as 302
