微信公众号实现会员卡领取功能


            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) ? "http://" : "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) ? "http://" : "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 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id

       cardExt: '{"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>
