我读了很多论坛主题,但没有找到任何符合我需要的答案使用CodeIgniter重写url,codeigniter,seo,codeigniter-routing,Codeigniter,Seo,Codeigniter Routing,我读了很多论坛主题,但没有找到任何符合我需要的答案 我正在运行一个博客系统,每篇文章的当前URL如下:www.example.com/controller/method/id。然而,对于每一篇文章,我都有一个存储在数据库中的标题,并且希望在url中使用该标题,因此它看起来是这样的:www.example.com/title您好,您需要大量的代码,而您自己没有做任何研究 最好的方法是将id与标题一起使用:http://www.example.com/id/long-title这比只使用标题要好得多
我正在运行一个博客系统,每篇文章的当前URL如下:
www.example.com/controller/method/id
。然而,对于每一篇文章,我都有一个存储在数据库中的标题,并且希望在url中使用该标题,因此它看起来是这样的:www.example.com/title
您好,您需要大量的代码,而您自己没有做任何研究
最好的方法是将id与标题一起使用:http://www.example.com/id/long-title
这比只使用标题要好得多,因为:
www.example.com/1
(这将使用301头重定向到/1/title
)或使用(生成)www.example.com/1/title
链接,但是如果生成类似以下url的url:/1/假标题
(标题对于id 1无效,它将不会重定向到正确的标题)
此解决方案对SEO很友好。很抱歉,我明天会尝试,我现在正在进行另一个项目,我将更新主题。感谢您的帮助我已经尝试了您的解决方案,它可以工作,但我想删除url中的“/front/post/”是否可能?再次感谢。它的工作方式,你只需要生成这样的链接
example.com/id/title
或example.com/id
(重定向到example.com/id/title
),请重新阅读答案。
