这篇文章主要介绍了微信公众号实现会员卡领取功能的相关资料,需要的朋友可以参考下

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=$nonceStr&timestamp=$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;  }

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;  }
