分享微信公眾號實現會員卡領取的功能

這篇文章主要介紹了微信公眾號實現會員卡領取功能的相關資料,需要的朋友可以參考下

1、會員卡的領取也需要js-sdk接口（可以參考獲取微信公眾號取得使用者的地理位置資訊）（借鏡網址：http://gaoboy.com/article/25.html）

2、 比取得使用者地理位置資訊多了一個是需要單獨取得簽章包，簽章方式也和取得使用者地理位置的不同（這裡再說一次取得簽章包的方式）

      取得js-sdk簽章包：

#           1、目前的url、時間戳記、隨機字串、jsapiticket進行組合

##

 //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; 
 }

//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; 
 }

1控制器中的程式碼：

  //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: &#39;<?PHP echo $signPackage["appId"];?>&#39;,
 timestamp: &#39;<?php echo $signPackage["timestamp"];?>&#39;,
 nonceStr: &#39;<?php echo $signPackage["nonceStr"];?>&#39;,
 signature: &#39;<?php echo $signPackage["signature"];?>&#39;,
 jsApiList: [
  // 所有要调用的 API 都要加到这个列表中
  &#39;addCard&#39;
  ]
   });
wx.ready(function(){
        //添加卡券
    document.querySelector(&#39;#addCard&#39;).onclick = function () {
     wx.addCard({
      cardList: [
      {
       cardId: "",//微信公众号内创建的会员卡的id
       cardExt: &#39;{"timestamp":"<?php echo $huiyuanPackage[&#39;timestamp&#39;] ?>","signature":"<?php echo $huiyuanPackage[&#39;signature&#39;] ?>"}&#39;//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: &#39;__CONTROLLER__/editHuiYuan&#39;,
      type: &#39;post&#39;,
      dataType: &#39;json&#39;,
      data: {is_LingQu: &#39;1&#39;,user_id:"<?php echo $user[&#39;user_id&#39;] ?>"},
      success:function(){
      $("#addCard").html("我的会员卡");
      }
      })
      }
     });
    };
   });
</script>
