简单实现淘宝API调用

简单实现淘宝API调用

简单实现了淘宝API的调用的类，暂时没有考虑session，可以参照淘宝api实现各种功能，比如获取宝贝详情、图片链接等。欢迎提建议

<?php
 
class TaobaoApi {
    /*
     * 定义并初始化参数数组，某些固定参数可写在这个位置
     */
 
    protected $_param = array(&#39;app_key&#39; => &#39;21572060&#39;, &#39;v&#39; => &#39;2.0&#39;,
        &#39;sign_method&#39; => &#39;md5&#39;, &#39;format&#39; => &#39;xml&#39;);
    /*
     * Sign值存储变量
     */
    protected $_sign;
    /*
     * 应用密码存储变量
     */
    public $secret = &#39;your secret&#39;;
    /*
     * 请求URL存储变量
     */
    protected $_url;
 
    public function run() {
        $this->createSign();
        $this->createRequestUrl();
        return $this->requestData();
    }
 
    /*
     * 通过魔法赋值向参数数组写入数据
     * @param string $name 数组名
     * @param string $value 数组键值
     */
 
    public function __set($name, $value) {
        $this->_param[$name] = $value;
    }
 
    /*
     * 组建Sign
     * @global $this->_param 参数数组
     * @global $this->secret 应用密钥
     */
 
    protected function createSign() {
        $this->_param[&#39;timestamp&#39;] = date(&#39;Y-m-d H:i:s&#39;);
        ksort($this->_param, SORT_STRING); //数组按键值排序
        $tmp = &#39;&#39;;
        foreach ($this->_param as $key => $value) {
            $tmp.= $key . $value;
        }
        $this->_sign = strtoupper(md5($this->secret . $tmp . $this->secret));
    }
 
    /*
     * 由参数和Sign值组合成请求URL
     * @global $this->_param
     * @global $this->url
     */
 
    protected function createRequestUrl() {
        $this->_param[&#39;timestamp&#39;] = urlencode($this->_param[&#39;timestamp&#39;]);
        $this->_url = &#39;http://gw.api.taobao.com/router/rest?sign=&#39; . $this->_sign;
        foreach ($this->_param as $key => $value) {
            $this->_url.=&#39;&&#39; . $key . &#39;=&#39; . $value;
        }
    }
 
    /*
     * 获取数据
     */
 
    protected function requestData() {
        return file_get_contents($this->_url);
    }
 
}
 
$a = new TaobaoApi();
//下面只要写入淘宝API规定必须传入的参数
$a->method = &#39;taobao.item.get&#39;;
$a->fields = &#39;desc,nick&#39;;
$a->app_key = &#39;your key&#39;;
$a->secret = &#39;your secret&#39;;
$a->num_iid = 16096610668;
//默认以xml方式输出
echo $a->run();
?>
