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

1、會員卡的領(lǐng)取也需要js-sdk接口（可以參考獲取微信公眾號獲取用戶的地理位置信息）（借鑒網(wǎng)址：http://gaoboy.com/article/25.html）

2、 比獲取用戶地理位置信息多了一個是需要單獨獲取簽名包，簽名方式也和獲取用戶地理位置的不同（這里再說一下獲取簽名包的方式）

????? 獲取js-sdk簽名包：

?????????? 1、當(dāng)前的url、時間戳、隨機字符串、jsapiticket進行組合????????????????

 //調(diào)用js-sdk的簽名包
 public function getSignPackage() {
 $jsapiTicket = $this->getJsApiTicket();
 // 注意 URL 一定要動態(tài)獲取，不能 hardcode.（獲取當(dāng)前網(wǎng)頁的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //時間戳
 $timestamp = time();
 //隨機字符串獲取
 $nonceStr = $this->createNonceStr();
 // 這里參數(shù)的順序要按照 key 值 ASCII 碼升序排序
 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";
 //生成字符串是用來簽名用的
 $signature = sha1($string);
 $signPackage = array(
  "appId"  => $this->appid,
  "nonceStr" => $nonceStr,
  "timestamp" => $timestamp,
  "url"  => $url,
  "signature" => $signature,
  "rawString" => $string
 );
 return $signPackage; 
 }

獲取會員卡簽名包：

//使用會員卡領(lǐng)取的簽名包
 public function getHuiYuanSignPackage() {
 $apiTicket = $this->getApiTicket();
 // 注意 URL 一定要動態(tài)獲取，不能 hardcode.（獲取當(dāng)前網(wǎng)頁的url）
 $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
 $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
 //時間戳
 $timestamp = time();
 //隨機字符串獲取
 // $nonceStr = $this->createNonceStr();
 // 這里參數(shù)的順序要按照 key 值 ASCII 碼升序排序
 $string = $timestamp.$apiTicket."pVYA_t3RCVF_yhNcO6QCeAmb-1UI";
 //生成字符串是用來簽名用的
 $signature = sha1($string);
 $signPackage = array(
  "timestamp" => $timestamp,
  "signature" => $signature,
 );
 return $signPackage; 
 }

詳細代碼說明：

HTML頁面：

  //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">
//配置信息驗證接口（填寫的js-sdk獲取的簽名包的參數(shù)）
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: [
  // 所有要調(diào)用的 API 都要加到這個列表中
  &#39;addCard&#39;
  ]
   });
wx.ready(function(){
        //添加卡券
    document.querySelector(&#39;#addCard&#39;).onclick = function () {
     wx.addCard({
      cardList: [
      {
       cardId: "",//微信公眾號內(nèi)創(chuàng)建的會員卡的id
       cardExt: &#39;{"timestamp":"<?php echo $huiyuanPackage[&#39;timestamp&#39;] ?>","signature":"<?php echo $huiyuanPackage[&#39;signature&#39;] ?>"}&#39;//會員卡的簽名包
      }
      ],
     //成功之后的回調(diào)的函數(shù)(通過回調(diào)函數(shù)該表數(shù)據(jù)庫是否領(lǐng)取會員卡的狀態(tài))
      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("我的會員卡");
      }
      })
      }
     });
    };
   });
</script>
