微信公众号实现会员卡领取功能

前端之家收集整理的这篇文章主要介绍了微信公众号实现会员卡领取功能前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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:

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

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:

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,); return $signPackage; }

控制器中的代码:

类库:

GetSignPackage();//获取js-sdk签名包 $huiyuanPackage = $jssdk->getHuiYuanSignPackage();获取会员卡签名包 //获取用户信息 $user = M('user')->where(array('user_id' => $user_id))->find(); //产品收藏数量统计 $goods_count = M('goods_shoucang')->where(array('user_id' => $user_id))->count(); //门店收藏数量统计 $shop_count = M('shop_shoucang')->where(array('user_id' => $user_id))->count(); }else{ //判断该用户是否存在 $model = new \Home\Model\WechatModel(); $openid_accesstoken = $model->openId(); $rst = M('user')->where(array('user_openid' => $openid_accesstoken['openid']))->find(); if($rst){ session('openid',$openid_accesstoken['openid']); session('user_id',$rst['user_id']); $jssdk = new \Home\Model\WechatModel(); $signPackage = $jssdk->GetSignPackage(); $huiyuanPackage = $jssdk->getHuiYuanSignPackage(); //获取用户信息 $user = M('user')->where(array('user_id' => $rst['user_id']))->find(); //产品收藏数量统计 $goods_count = M('goods_shoucang')->where(array('user_id' => $rst['user_id']))->count(); //门店收藏数量统计 $shop_count = M('shop_shoucang')->where(array('user_id' => $rst['user_id']))->count(); }else{ $userInfo = $model->getOpenId($openid_accesstoken['openid'],$openid_accesstoken['access_token']); $data = array( 'user_img' => $userInfo['headimgurl'],'user_openid' => $userInfo['openid'],'user_name' => filter($userInfo['nickname']),'user_register_time' => time(),'city' => $userInfo['province'].'-'.$userInfo['city'],); $id = M('user')->add($data); session('openid',$userInfo['openid']); session('user_id',$id); $jssdk = new \Home\Model\WechatModel(); $signPackage = $jssdk->GetSignPackage(); $huiyuanPackage = $jssdk->getHuiYuanSignPackage(); //获取用户信息 $user = M('user')->where(array('user_id' => $id))->find(); //产品收藏数量统计 $goods_count = M('goods_shoucang')->where(array('user_id' => $id))->count(); //门店收藏数量统计 $shop_count = M('shop_shoucang')->where(array('user_id' => $id))->count(); } } $this->assign('signPackage',$signPackage); $this->assign('huiyuanPackage',$huiyuanPackage); $this->assign('user',$user); $this->assign('shop_count',$shop_count); $this->assign('goods_count',$goods_count); $this->display(); }
