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; }
