Facebook PHP SDK& Codeigniter：无法加载配置 [英] Facebook PHP SDK & Codeigniter: Unable to load config

问题描述

my config / facebook.php

my config/facebook.php

$config['appId']        = 'XXXXX';
$config['secret']       = 'XXXX';
$config['fb_access_token'] = 'XXXXXX';

我的控制器：

$this->load->library('Facebook');  
echo $this->config->item('fb_access_token');

不会为令牌输出任何内容？但我知道库正在加载，因为我可以调用getAppID确定。

Outputs nothing for the the token? yet I know the library is loading as I can call getAppID ok. It just doesn't seem to be loading this config file.

也尝试过这个控制器：

$this->config->load("facebook",TRUE);
$config = $this->config->item('facebook');
$this->load->library('facebook', $config);

推荐答案

加载库的正确方法：

$this->config->load('facebook');
$config = array(
               'appId' => $this->config->item('appId'),
               'secret' => $this->config->item('secret'),
);
$this->load->library('facebook', $config);  

您之后才可以设置访问令牌：

You can set the access token only afterwards:

$this->facebook->setAccessToken($this->config->item('fb_access_token'));
