以http://localhost/basic/web/index.php?r=article/index为例
echo \yii\helpers\Url::base();
//输出/basic/web
echo \yii\helpers\Url::base(true)
//输出http://localhost/basic/web
//home是输出首页,加上true是输出加域名的首页
echo \yii\helpers\Url::home();
//输出/basic/web/index.php
echo\yii\helpers\Url::home(true);
//输出http:://localhost/basic/web/index.php
//当前的Url
echo \yii\helpers\Url::current();
//输出/basic/web/index.php?r=article/index
//to和toRoute都是生成Url,后面加true都是生成带域名的Url
echo \yii\helpers\Url::to([‘article/add’]);
//输出/basic/web/index.php?r=article/add
echo \yii\helpers\Url::to([‘article/edit’,’id’=>1]);
//输出/basic/web/index.php?r=article/add&id=1
echo \yii\helpers\Url::to([‘article/add’],true);
//输出http://localhost/basic/web/index.php?r=article/add
echo \yii\helpers\Url::to([‘article/edit’,’id’=>1],true);
//输出http://localhost/basic/web/index.php?r=article/add&id=1
echo\yii\helpers\Url::toRoute([‘article/add’]);
//输出/basic/web/index.php?r=article/add
echo \yii\helpers\Url::toRoute([‘article/edit’,’id’=>1]);
//输出/basic/web/index.php?r=article/add&id=1
echo \yii\helpers\Url::toRoute([‘article/add’],true);
//输出http://localhost/basic/web/index.php?r=article/add
echo\yii\helpers\Url::toRoute([‘article/edit’,’id’=>1],true);
//输出http://localhost/basic/web/index.php?r=article/add&id=1
//to和toRoute之间的区别,传入string时,to 会直接把string当成url和toRoute则会解析
echo\yii\helpers\Url::to(‘article/add’);
//输出article/add
echo\yii\helpers\Url::toRoute(‘article/add’);
//输出/basic/web/index.php?r=article/add
