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>
