Php 重写路径取决于参数值Yii

我在Yii中有几个规则，允许我重写一些路由，其中每个路由都将作为get参数传递给操作

'<department>' => 'products/index',
'<department>/<category>' => 'products/index',

“”=>“产品/索引”，
“/”=>“产品/索引”，

我想显式地编写一个规则，根据参数值的不同，将url更改为我想要的任何内容

例如，现在我有一个这样的URL www.mysite.com/Books+%26+铅笔，由于此规则被重写

'=>“产品/索引”

，这是正常的

如果有人知道如何编写一条规则，比较deparment属性的值，然后将其重写为我想要的任何内容，那么我想将该URL更改为www.mysite.com/books-pencils

谢谢

首先，如果您想更改URL，您应该执行重定向（在本例中）。要实现此逻辑，可以使用

Url管理器配置：

'rules' => array(
    // custom url rule class
    array(
        'class' => 'application.components.MyUrlRule',
    ),
)

MyUrlRule类：

class MyUrlRule extends CBaseUrlRule
{
    public function createUrl($manager,$route,$params,$ampersand)
    {
        // Logic used to create url.
        // If you do not create urls using Yii::app()->createUrl() in your app,
        // you can leave it empty.
    }

    public function parseUrl($manager,$request,$pathInfo,$rawPathInfo)
    {
        // modify url
        $pathInfoCleaned = strtolower(preg_replace('+%26+', '-', $pathInfo));

        // redirect if needed
        if ($pathInfo !== $pathInfoCleaned) {
            $request->redirect($pathInfoCleaned, true, 301);
        }

        // parse params from url
        $params = explode('/', $pathInfo);
        if (isset($params[0])) {
            $_GET['department'] = $params[0];
            if (isset($params[1])) {
                $_GET['category'] = $params[1];
            }
        }

        return 'products/index';
    }
}

您可以使用自定义类来处理特殊请求。 我使用了类似的方法，从数据库中获取自定义URL：

 'urlManager'=>array(
            'rules'=>array(
                array(
                    'class' => 'application.components.UrlRule',
                ),
            ),
        ),

然后创建类似以下内容的custo类：

<?php

Yii::import("CBaseRule");

class UrlRule extends CBaseUrlRule
{
    public function createUrl($manager,$route,$params,$ampersand)
    {
        // check for my special case of URL route, if not found, then return the unchaged route
        preg_match("/^(.+)\/(.+)$/", $route, $r);
        if(!is_array($r) or !isset($r[1]) or !isset($r[2])) {
            return $route;
        }

        // handle your own route request, and create your url
        $url = 'my-own-url/some-thing';

        // check for any params, which i also want to add
        $urlParams = $manager->createPathInfo($params,"=","&");

        $return = trim($url,'/');
        $return.= $urlParams ? "?" . $urlParams : "";

        return $return;
    }

    public function parseUrl($manager,$request,$pathInfo,$rawPathInfo)
    {

        // handle my special url request
        $controller = '....';
        $action = '.....';

        // return the controller/action that should be used     
        return lcfirst($controller)."/".$action;
    }
}

// check my route and params, and if I need to redirect
$request->redirect('/your/new/url/?params=bla',true,'301');
