<link rel="canonical" href="{$eyou.field.pageurl}">如何调用唯一的url,比如以下四个链接是同一个链接
https://demo.yiyocms.com/gongsijianjie/
https://demo.yiyocms.com/index.php/gongsijianjie/
https://demo.yiyocms.com/8/
https://demo.yiyocms.com/index.php/8/
我只想调用https://demo.yiyocms.com/gongsijianjie/,也就是说打开https://demo.yiyocms.com/index.php/gongsijianjie/,调用的也是https://demo.yiyocms.com/gongsijianjie/。
