本文實例講述了Yii2針對指定url的生成及圖片等的引入方法。分享給大家供大家參考，具體如下：

// /index?r=site/index
echo Url::to(['site/index']);
// /index?r=site/index&src=ref1#name
echo Url::to(['site/index', 'src' => 'ref1', '#' => 'name']);
// the currently requested URL
echo Url::to();
// /images/logo.gif
echo Url::to('@web/images/logo.gif');
// images/logo.gif
echo Url::to('images/logo.gif');
// http://www.example.com/images/logo.gif
echo Url::to('@web/images/logo.gif', true);
// https://www.example.com/images/logo.gif
echo Url::to('@web/images/logo.gif', 'https');
// /index?r=site/index
echo Url::toRoute('site/index');
// /index?r=site/index&src=ref1#name
echo Url::toRoute(['site/index', 'src' => 'ref1', '#' => 'name']);
// http://www.example.com/index.php?r=site/index
echo Url::toRoute('site/index', true);
// https://www.example.com/index.php?r=site/index
echo Url::toRoute('site/index', 'https');
echo Yii::$app->urlManager->createUrl('site/index')
