http://192.168.1.136/dashboard/Projects/CodeIgniter-3.1.11/index.php/calls/call_id

并面对404页面未找到错误。

我想将call_id传递给控制器。请告诉我我做错了什么。

这是控制器

class Calls extends CI_Controller {
// I WANT TO ACCESS call_id HERE
function __construct() {
parent::__construct();
}
public function index($abc) {
$this->load->helper('url');
$call =  $this->uri->segment(3);
$data = array('call_id' => $call, 'bar' => 'world');
$this->load->view('Pages/MyAjax.php', $data);
}
}

这是路由器配置

defined('BASEPATH') OR exit('No direct script access allowed');
$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

这是配置.php

defined('BASEPATH') OR exit('No direct script access allowed');
$config['base_url'] = '';
$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'REQUEST_URI';
$config['url_suffix'] = '';

我想在controller访问call_id。

Answer 1

像这样向index()添加参数index($call_id = NULL)

控制器

class Calls extends CI_Controller {
function __construct() {
parent::__construct();
}
public function index($call_id = NULL) {
// $this->load->helper('url');
// $call =  $this->uri->segment(3);
$data = array('call_id' => $call_id, 'bar' => 'world');
$this->load->view('Pages/MyAjax.php', $data);
}
}

和网址

http://192.168.1.136/dashboard/Projects/CodeIgniter-3.1.11/index.php/calls/index/30

其中，上述网址30中的最后一个片段是call_id
