使用Codeigniter 3处理尾随斜杠 [英] Handle trailing slash with Codeigniter 3

问题描述

我有一个包含以下网址的文章数据库:

I have a database of articles with the urls as follow:

person/albert-einstein/(斜线)

person/albert-einstein/1 (不带斜杠)

我想知道在Codeigniter 3中处理URL尾部斜杠的最佳方法是什么?

And I was wondering what was the best way to handle url trailing slashes in Codeigniter 3?

这是我到目前为止所做的/测试的事情:

This is what I have done/test so far:

echo site_url('person/albert-einstein/'); # http://localhost/person/albert-einstein                              
echo base_url('person/albert-einstein/'); # http://localhost/person/albert-einstein                              
echo site_url('person/albert-einstein/1'); # http://localhost/person/albert-einstein/1                 
echo base_url('person/albert-einstein/1'); # http://localhost/person/albert-einstein/1

然后我编辑了 config.php 进行设置:

Then I edited config.php to set:

$config['url_suffix'] = '/';

并再次打印网址:

echo site_url('person/albert-einstein/'); # http://localhost/person/albert-einstein/                              
echo base_url('person/albert-einstein/'); # http://localhost/person/albert-einstein                              
echo site_url('person/albert-einstein/1'); # http://localhost/person/albert-einstein/1/            
echo base_url('person/albert-einstein/1'); # http://localhost/person/albert-einstein/1

现在，我可以选择 site_url()或 base_url()来打印带有斜杠或不带斜杠的url.但是现在我的观点是，我必须非常小心使用哪一个，而我宁愿使用一个尊重我传递的网址的函数，如果有则返回带有斜杠的网址，如果没有则不加一个有它.

Now I can select site_url() or base_url() to print the url with trailing slash or without it. But now on my views I have to be very careful to which one I use and I'd rather use a function that respects the url I pass and return it with trailing slash if it have or don't add one if it doesn't have it.

是的，我可以肯定地扩展帮助程序，并编写一个函数: print_url()，该函数可以实现我想要的功能，但是我想查看是否在此处缺少某些内容.谢谢你.

And yes, I can definitely extend the helper and write a function like: print_url() that does what I want but I wanted to see if there's something I'm missing here. Thank you.

推荐答案

您可以使用apache rewite规则强制使用斜杠:

You can use apache rewite rule for forcing trailing slash:

RewriteCond %{REQUEST_URI} /+[^\.]+$
RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]

要删除结尾的斜杠，可以使用:

For removing trailing slash you can use:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]

我使用了 .htaccess 片段的良好基础.
