php/expression引擎-将所有URL从一个URL段重定向到另一个URL片段

我认为，一行.htaccess确实是这里最简单的解决方案。

RedirectMatch ^/site/code_single/(.+)$ /main/code-item/$1 [L,R=301]

如果您需要php解决方案，您可以在执行任何其他代码之前调用此函数（位于主index.php.的顶部

我使用它来重新路由代码点火器URL，而不保持重复的URL有效如果你使用routes.php 会发生什么

对于那些想知道为什么的人？谷歌喜欢301重定向，讨厌双重内容。Codeigniter有一个很好的功能，可以制作自己的"路线"，这样你就可以在需要的地方使用自己的url。问题是，原始的"不需要的/丑陋的"url仍然可以访问，如果谷歌发现了这一点，你的页面的seo排名就会暴跌。发现这一点后，我试图在codeigniter中发现任何类型的301重定向功能，但每次都碰壁了，.htaccess重定向会随着时间的推移而失败（我不是唯一一个，stackoverflow已经充满了它）所以这就是我决定写这篇文章的原因，要记住速度，尽可能少地进行"花式操作"来完成任务。

您必须在代码点火器的第一个index.php文件的顶部添加这些行

require ('myobjects_x.php');
redirecttoHTTPS();

我已经调用了下面的文件myobjects_x.php，并将其保存在我的基本目录中，其中codeigniter的第一个index.php文件是.

谢谢-我想我在网上找到了一个很好的解决方案，让EE动态生成301重定向的URL列表：

http://www.blue-dreamer.co.uk/blog/entry/expressionengine-301-redirects-made-easier/

有一个名为Detour Pro的插件，允许您在EE中的一个简单管理面板内创建301和302重定向（它甚至提供了您建立的每个重定向的指标）。如果你有很多重定向需要管理，并且想避免在htaccess中这样做，那么值得一看——特别是如果不是所有的重定向都已经映射好，并且你需要客户端（在合理的范围内）能够自己创建这样的重定向。
