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) ? "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=$nonceStr×tamp=$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 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>

控制器中的代码：

  if($user_id){
  $jssdk = new HomeModelWechatModel();

  //获取用户信息
