16.8.1 HTML5网页中领取卡券
HTML5网页中领取卡券是微信JS-SDK接口的一个功能。生成卡券ID之后，将其传入HTML5页面中，再使用JS-SDK接口进行领取。
HTML5网页中领取卡券的代码如下。
1 <?php
2 require_once('wxjssdk.class.php');
3 $weixin = new class_weixin;
4 $signPackage = $weixin->GetSignPackage;
5 $cardapi_ticket = $weixin->getCardApiTicket;
6
7 $card_id = "piPuduN0wOytmRlSyeNJQToE7BIU";
8 $obj['api_ticket'] = $cardapi_ticket;
9 $obj['timestamp'] = strval(time);
10 $obj['nonce_str'] = $weixin->createNonceStr;
11 $obj['card_id'] = $card_id;
12 $signature = $weixin->get_cardsign($obj);
13
14 ?>

上述代码中，需要注意的地方是卡券的签名部分，读者可以参考第14章的代码实现。
