微信公众号实现会员卡领取

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; 
  }
