在启用漂亮网址后，Yii2旧链接无法正常工作

Question

I'm currently updating an existing live website to use pretty urls. I've got the urls working, but my problem is that after I've enabled pretty urls all of the old links from sites like Google etc will stop working. They simply redirect to the front page. Examples; Old url: http://www.dreambulgarianproperties.com/index.php?r=properties%2Fproperty%2Fview&id=37 Redirects to the front page

New url: http://www.dreambulgarianproperties.com/properties/property/view?id=37 as it should look from both urls.

My .htaccess file is this:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule  ^(.*)$ index.php/$1

and my UrlManager config is this;

'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'enableStrictParsing' => false,
        'rules' => [
            '<action:\w+>' => 'site/<action>'
        ],
    ],

The site works fine, I'm just worried about losing Google traffic if I change the urls.

Is there a way of telling Yii to continue parsing old urls, while displaying and handling the new, pretty urls?

Answer 1

I found away to do this neatly. I extended the UrlManager and updated the parseRequest() method like this;

public function parseRequest($request) {
    $url = Yii::$app->request->url;
    if ($pos = strpos($url, 'index.php?r=') == false) {
        return parent::parseRequest($request);
    }
    Yii::trace('Pretty URL not enabled. Using default URL parsing logic.', __METHOD__);
    $route = $request->getQueryParam($this->routeParam, '');
    if (is_array($route)) {
        $route = '';
    }

    return [(string) $route, []];
}

Now if there is a query string like index.php?r=controller/action it will process it, otherwise it passes control back to the parent UrlManager for normal processing.

To keep my seo up to date I've added a canonical link in the header of every page so Google knows to use the pretty url for indexing.
