我是 CodeIgniter 的新手,但到目前为止我很喜欢它!
我正在将 Shopify API 移植到 CodeIgniter 库,但我遇到了一个小问题,我一生都无法弄清楚!
我收到一个未定义的变量错误,我觉得这是我想念的非常简单的东西,但我不明白为什么它不起作用。以下是自定义类的相关代码:
class Shopify
{
public $_api_key;
public $_shared_secret;
//public $_shops_myshopify_domain;
public function __construct ()
{
$this->_assign_libraries();
$this->_api_key = $this->config->item('api_key', 'shopify');
$this->_shared_secret = $this->config->item('shared_secret', 'shopify');
//$this->_shops_myshopify_domain =$this->config->item('shops_myshopify_domain', 'bitauth');
}
public function shopify_app_install_url($shop_domain)
{
return "http://$shop_domain/admin/api/auth?api_key=$_api_key";
}
public function _assign_libraries()
{
if($CI =& get_instance())
{
$this->load = $CI->load;
$this->config = $CI->config;
$this->load->config('shopify', TRUE);
return;
}
}[/code]
这是我创建的配置文件中的代码:
/**
* Your shared secret
*/
$config['shared_secret'] = 'changed for posting on forum';
/**
* Your Shopify API key
*/
$config['api_key'] = 'changed for posting on forum';
这是控制器中的相关代码:
Class shopifyPermission extends CI_Controller {
function __construct ()
{
parent::__construct();
// Load the Shopify API library
$this->load->library('shopify.php');
// Require url helper to perform the header redirect
$this->load->helper('url');
}
function index() {
//require 'shopify.php';
$shop_domain = "changed.myshopify.com";
$url = $this->shopify->shopify_app_install_url($shop_domain);
//redirect($url);
$data['url'] = $url;
$this->load->view('shopifyPermission_view', $data);
}
}
我得到的错误如下: 遇到 PHP 错误
严重性:通知
消息:未定义变量:_api_key
文件名:库/Shopify.php
行号:34
因此,即使我有一个有效的 api 密钥,显然也没有从配置文件中提取 api 密钥?当我执行回显时,它会显示整个 URL,但 API 密钥不存在。我不知道该怎么做,不胜感激!谢谢!
