分享微信公众号实现会员卡领取的功能

这篇文章主要介绍了微信公众号实现会员卡领取功能的相关资料,需要的朋友可以参考下

1、会员卡的领取也需要js-sdk接口（可以参考获取微信公众号获取用户的地理位置信息）（借鉴网址：http://gaoboy.com/article/25.html）

2、 比获取用户地理位置信息多了一个是需要单独获取签名包，签名方式也和获取用户地理位置的不同（这里再说一下获取签名包的方式）

获取js-sdk签名包：

1、当前的url、时间戳、随机字符串、jsapiticket进行组合

//调用js-sdk的签名包 public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); // 注意 URL 一定要动态获取，不能 hardcode.（获取当前网页的url） $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://"; $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; //时间戳 $timestamp = time(); //随机字符串获取 $nonceStr = $this->createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url"; //生成字符串是用来签名用的 $signature = sha1($string); $signPackage = array("appId"=> $this->appid,"nonceStr" => $nonceStr,"timestamp" => $timestamp,"url"=> $url,"signature" => $signature,"rawString" => $string ); return $signPackage;}

获取会员卡签名包：

//使用会员卡领取的签名包 public function getHuiYuanSignPackage() { $apiTicket = $this->getApiTicket(); // 注意 URL 一定要动态获取，不能 hardcode.（获取当前网页的url） $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://"; $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; //时间戳 $timestamp = time(); //随机字符串获取 // $nonceStr = $this->createNonceStr(); // 这里参数的顺序要按照 key 值 ASCII 码升序排序 $string = $timestamp.$apiTicket."pVYA_t3RCVF_yhNcO6QCeAmb-1UI"; //生成字符串是用来签名用的 $signature = sha1($string); $signPackage = array("timestamp" => $timestamp,"signature" => $signature, ); return $signPackage;}

详细代码说明：

HTML页面：

//引入微信js文件<script alt="分享微信公众号实现会员卡领取的功能" src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script><script type="text/JavaScript">//配置信息验证接口（填写的js-sdk获取的签名包的参数）wx.config({ debug: false, appId: '<?PHP echo $signPackage["appId"];?>', timestamp: '<?php echo $signPackage["timestamp"];?>', nonceStr: '<?php echo $signPackage["nonceStr"];?>', signature: '<?php echo $signPackage["signature"];?>', jsApiList: [// 所有要调用的 API 都要加到这个列表中'addCard']});wx.ready(function(){//添加卡券document.querySelector('#addCard').onclick = function () {wx.addCard({cardList: [{cardId: "",//微信公众号内创建的会员卡的idcardExt: '{"timestamp":"<?php echo $huiyuanPackage['timestamp'] ?>","signature":"<?php echo $huiyuanPackage['signature'] ?>"}'//会员卡的签名包}],//成功之后的回调的函数(通过回调函数该表数据库是否领取会员卡的状态)success: function (res) {$.ajax({url: '__CONTROLLER__/editHuiYuan',type: 'post',dataType: 'json',data: {is_LingQu: '1',user_id:"<?php echo $user['user_id'] ?>"},success:function(){$("#addCard").html("我的会员卡");}})}});};});</script>

控制器中的代码：
