关于yii2里面的\yii\helpers\Url组件

    在完成实验室网站的yii2移植过程中，发现在处理网页的跳转中需要经常用到\yii\helpers\Url组件，所以今天来总结一下。

                

       //以http://localhost/basic/web/index.php?r=article/index为例

              

                 //base输出根目录

                 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

              由于在打字过程中没有注意区分英文标点的切换，所以上面的语句如果有错，需要修改为英文标点即可。
