为什么在codeigniter中链接两个页面时会出现404错误或奇怪的url？

我试图在codeigniter中链接两个页面（主页和关于页面）。但是当我点击about页面链接时

<a href="aboutpage">Click here for the About page</a>

每次单击主页链接或关于页面链接时，都会添加一个站点

以下是我的控制器站点。php：-

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

}

这是我的视图\u home.php

<div id="container">
<h1>Welcome to homepage</h1>

<div id="body">

    <p>This is Homepage</p>
    <br />

    <a href="aboutpage">Click here for the About page</a>
</div>

<p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>

<div id="container">
<h1>Welcome to About Page</h1>

<div id="body">

    <p>This is About Page</p>
    <br />

    <a href="homepage">Click here for the Homepage</a>
</div>

<p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>

欢迎浏览网页
这是主页



以{exposed\u time}秒呈现的页面

这是我关于.php的视图

<div id="container">
<h1>Welcome to homepage</h1>

<div id="body">

    <p>This is Homepage</p>
    <br />

    <a href="aboutpage">Click here for the About page</a>
</div>

<p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>

<div id="container">
<h1>Welcome to About Page</h1>

<div id="body">

    <p>This is About Page</p>
    <br />

    <a href="homepage">Click here for the Homepage</a>
</div>

<p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>

欢迎来到关于页面
这是关于佩奇的

我甚至试着看看我的.htaccess文件是否有问题。但一切似乎都很好

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

嗨，我试着做了这个改变。但是现在链接没有出现。然后我尝试了关于我们的“id=”lnk_aboutus“>，效果很好。这种方法也是正确的方法吗？这种方法似乎可以在不更改配置的情况下工作file@Stacy不，这不是正确的方法。你应该保持配置不变，而是使用

site\u url（）

在您需要回显网站url时运行。@Stacy您在控制器中添加了url帮助程序了吗？如果没有，请将$this->load->helper（'url'）；添加到您的控制器或在config/autoload.php$autoload['helper']=array（'url'）；注意，

site_url（）

是为此提供的功能。例如，要链接到

domain.com/foo/bar

，您只需使用

-即可使用基本URL。这本身不是Codeigniter问题。您只需在URL前面添加斜杠即可。例如

href=“/site/aboutpage“

。在链接的开头添加正斜杠会使链接相对于您的主页，这相当于

http://yoursite.com/site/aboutpage

。如果没有斜杠，链接将相对于当前页面打开，因此它们将继续添加到url add infinitum。
