php - 试图获取非对象的属性 - CodeIgniter 错误

Question

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Trying to get property of non-object Here

我将 API 放在应用程序文件夹之外

我将是 KloutAPIv2.class

<?php

我创建了一个控制器作为 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();

    }

}

?>

Twitter ID 与 Twitter 屏幕名称的适应略有不同：URL 结构不同，“network”字符串也不同：

ID呼叫时，网络为“tw”
用网名打电话时，网络是“twitter”

[这主要是我们 API Proxy 的路由匹配系统的一种解决方法]。

所以，通过 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$this->load->file，我查看 Code Igniter 用户指南$this->load->file：

$this->load->file('文件路径/文件名', true/false)

这是一个通用的文件加载功能。在第一个参数中提供文件路径和名称，它将打开并读取文件。默认情况下，数据会发送到您的浏览器，就像查看文件一样，但是如果您将第二个参数设置为 true（布尔值），它会将数据作为字符串返回。

所以，我的建议是使用图书馆。将您KloutAPIv2.class.php的文件放入klout.phpapplication/libraries 文件夹中并加载它$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);
