Question

我在yii2遇到了一个问题，用一些参数创建一个url，当时每个参数都可能被遗漏。例如：

site.com/index/param1/value1/param2/valu2/param3/value3/param4/value4

或者：

site.com/param2/value2/param4/value4

只有4个固定名称的参数。我试着搜索这个，但没有找到合适的文档。

public function createUrl ($ manager, $ route, $ params)
    {
        if ($ route === 'site / index') {
            if (isset ($ params ['ship']) OR isset ($ params ['map']) OR isset ($ params ['gamemode']) OR isset ($ params ['version'])) {
                return (isset ($ params ['ship']))? $ params ['ship']. '/' ''
                . (isset ($ params ['map']))? $ params ['map']. '/' ''
                . (isset ($ params ['gamemode']))? $ params ['gamemode']. '/' ''
                . (isset ($ params ['version']))? $ params ['version']. '/', '';
            }
        }
        return false;
    }

    public function parseRequest ($ manager, $ request)
    {
        $ pathInfo = $ request-> getPathInfo ();
        if (preg_match ('% ^ (\ w +) (/ (\ w +))? $%', $ pathInfo, $ matches)) {

        }
        return false;
    }

另外，我无法理解在parseRequest中要做什么以及在哪里使用$ params。

您可以像这样向urlManager添加一些规则：

'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            ...
            'site/param1/<param1:\w+>' => 'site/action',
            'site/param2/<param2:\w+>' => 'site/action',
            'site/param3/<param3:\w+>' => 'site/action',
            'site/param4/<param4:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param2/<param2:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param3/<param3:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param2/<param2:\w+>/param3/<param3:\w+>' => 'site/action',
            'site/param2/<param2:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param3/<param3:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param2/<param2:\w+>/param3/<param3:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param2/<param2:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param3/<param3:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param2/<param2:\w+>/param3/<param3:\w+>/param4/<param4:\w+>' => 'site/action',
            'site/param1/<param1:\w+>/param2/<param2:\w+>/param3/<param3:\w+>/param4/<param4:\w+>' => 'site/action',
            ...

这可能不是最优雅的方式，但它仍然有效。当有更多参数时会出现主要问题。
