Codeigniter 将GET参数传递给默认的欢迎控制器

我已经在我的服务器上安装了新的Codeigniter安装，我希望能够传递到默认控制器（welcome）获取参数

例如：

我希望欢迎控制器上的默认索引函数将获取'1234'作为get参数，但我不能让它工作任何想法

这是我的控制器代码：

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

class Welcome extends CI_Controller {

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *      http://example.com/index.php/welcome
     *  - or -
     *      http://example.com/index.php/welcome/index
     *  - or -
     * Since this controller is set as the default controller in
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        $this->load->view('welcome_message');

        // echo get parameter here = 1234
    }
}

你的控制器应该是这样的

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

/**
 * Index Page for this controller.
 *
 * Maps to the following URL
 *      http://example.com/index.php/welcome
 *  - or -
 *      http://example.com/index.php/welcome/index
 *  - or -
 * Since this controller is set as the default controller in
 * config/routes.php, it's displayed at http://example.com/
 *
 * So any other public methods not prefixed with an underscore will
 * map to /index.php/welcome/<method_name>
 * @see http://codeigniter.com/user_guide/general/urls.html
 */
public function index($number)
{
    //$this->load->view('welcome_message');

    echo get parameter here = 1234
}

}

在config.php中，可以启用查询字符串：

$config['enable_query_strings'] = TRUE;

使用此url访问方法的权限：

http://www.myserver.com/?id=1234

我认为这应该行得通。
在route.php文件中

// Would leave as your default controller
$route['default_controller'] = 'welcome';

// But add get query route here 
$route['number='] = 'welcome/index';

您需要在查询get开始时使用？，然后在这之后，任何其他url查询使用&

然后在控制器上

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

    public function index()
    {
        $this->load->helper('url');

        echo anchor('?number=1234', 'Home', array('target' => '_blank'));

        // http://www.example.com/index.php/?number=1234

        echo '</br>';

        echo $this->input->get('number');

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

您可以使用uri段

<?php echo $this->uri->segment(1);?>


使用重新映射功能

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

    public function _remap($method, $params = array())
    {

        if (method_exists($this, $method))
            return call_user_func_array(array($this, $method), $params);
        else
            return call_user_func_array(array($this, 'index'), $params);    
    }
    public function index($number)
    {
        //$this->load->view('welcome_message');

        echo get parameter here = 1234
    }

}

是否可以在不启用$config['enable_query_strings']=TRUE的情况下执行此操作？您应该这样调用控制器：对不起，您应该这样调用控制器：localhost:8000/projectname/classname/controllername/{parameters}
<?php echo $this->uri->segment(1);?>

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

    public function _remap($method, $params = array())
    {

        if (method_exists($this, $method))
            return call_user_func_array(array($this, $method), $params);
        else
            return call_user_func_array(array($this, 'index'), $params);    
    }
    public function index($number)
    {
        //$this->load->view('welcome_message');

        echo get parameter here = 1234
    }

}
