Php 在CodeIgniter上找不到页面

也许你能帮我。我的codeigniter设置有问题。这是一个全新的安装，我所做的只是对欢迎控制器执行以下操作：

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

class Welcome extends CI_Controller {

    function __construct()
    {
        parent::__construct();
    }

    function index()
    {
        $this->load->view('welcome_message');
    }

    function test()
    {
        echo "test";
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */

此错误（未找到HTTP 404）表示 那个Internet Explorer能够 连接到网站，但不连接页面 找不到你想要的。它是 可能该网页是 暂时不可用。 或者，该网站可能有 已更改或删除网页。对于 有关HTTP错误的更多信息， 请看帮助

如果我试图访问一个不存在的页面，我会得到404个错误，这是我所期望的。

尝试将您的uri\u协议设置为

$config['uri_protocol']=“请求_uri”；

这是我的访问权限

#如果我们没有安装mod_rewrite，所有404 #可以发送到index.php，一切正常。 #提交人：ElliotHaughin

a2enmod rewrite /etc/init.d/apache2
reload

嘿，约翰·内森，很高兴我能解决你的问题。您所要做的就是启用apache的mod rewrite

因为您没有使用apache的mod rewrite，code igniter一定是弄乱了一些重写规则，把您的表单数据弄乱了。

我建议您尝试使用uri\u协议。。。CI2对这些设置非常不合作。。。
