淘宝 API 有调用次数限制,一次 API 调用,可以最大返回40个商品的淘宝客链接,因此,在本函数内,如果需要批量生成的淘宝商品 num_iid 数大于40,将按照40个一次,分多次调用。如果调用淘宝 API 查询过的商品 num_iid,不管其是否有淘宝客链接(有些商品没有淘宝客推广链接),都将利用 Memcached 缓存起来,下次直接查缓存,不会重复调用淘宝 API。

/*********************************************

* 函数名:get_taobaoke_link ($num_iids)

* 函数用途:通过淘宝商品 num_iids 获取其对应的淘宝客手机版链接 

* 创建时间:2012-02-14

* 创建人:张宴 net@s135.com

* 参数说明:

*    $num_iids   淘宝商品ID(支持多个商品)数组,示例如下:

*          $num_iids[] = "13583512568";

*          $num_iids[] = "10809380078";

*          $num_iids[] = "10809380079";  

* 返回值:

*    下标为淘宝商品 num_iid ,值为淘宝客链接 click_url 的二维数组。如果无淘宝客链接,click_url 为空字符串,示例如下:

*          array(3) {

*            ["13583512568"]=>

*            string(191) "http://auction1.wap.taobao.com/auction/item_detail-0db2-13583512568.jhtml?tks=jUTwPLMDtUUNEZhqfEuTZqkZhGw1LA7%2BzCJBXCj27NpurHxjZN70Amg0DVaFU61pfnHwW%2FI4MZGm%0Awgb69kbb1NL8uwtu%2BDnyAunBCVDP"
