1、會員卡的領取也需要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、當前的url、時間戳、隨機字符串、jsapiticket進行組合
//調用js-sdk的簽名包 public function getSignPackage() { $jsapiTicket = $this->getJsApiTicket(); // 注意 URL 一定要動態獲取，不能 hardcode.（獲取當前網頁的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(); // 這里參數的順序要按照 key 值 ASCII 碼升序排序 $string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$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：
//使用會員卡領取的簽名包 public function getHuiYuanSignPackage() { $apiTicket = $this->getApiTicket(); // 注意 URL 一定要動態獲取，不能 hardcode.（獲取當前網頁的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：
