我是codeigniter的新手，我正在尝试将Klout API集成到codeigniter，我有这个错误说试图获取非对象的属性这里
我已将API放在应用程序文件夹的一侧
我将成为KloutAPIv2.class

我将控制器创建为klout.php
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class klout extends CI_Controller {
public $kloutapi_key;
function __construct() {
parent::__construct();
$this->load->file('./klout/KloutAPIv2.class.php');
$this->kloutapi_key = 'key';
}
public function kloutID() {
$network = "twitter";
$userid = 318066771330736;
$klout = new KloutAPIv2($this->kloutapi_key);
$kloutid = $klout->KloutIDLookupByID($network, $userid);
print_r($kloutid);
exit();
}
}
?>

适应Twitter ID与Twitter屏幕名称之间略有不同：URL结构不同，“网络”字符串不同：
[这主要是我们API Proxy的路由匹配系统的解决方法]。
所以，按ID： http://api.klout.com/v2/identity.json/tw/318066771330736?key=foo
按屏幕名称： http://api.klout.com/v2/identity.json/twitter?screenName=jack&key=foo

我认为您必须将代码作为库加载，而不是使用$this->load->file，我查看有关$this->load->file的Code Igniter用户指南：
$ this-＆gt; load-＆gt;文件（'filepath / filename'，true / false）
这是一个通用的文件加载功能。提供文件路径和名称 在第一个参数中，它将打开并读取文件。默认情况下 数据将被发送到您的浏览器，就像查看文件一样，但如果您 将第二个参数设置为true（布尔值），它将返回 数据为字符串。
所以，我的推荐是使用库。将您的KloutAPIv2.class.php放入应用程序/库文件夹中名为klout.php的文件中，然后加载$this->load->library('kout');
您可以在加载库时将参数传递给构造函数，如下例所示：
$params = array('type' => 'large', 'color' => 'red');
$this->load->library('Someclass', $params);
