微信公众号实现会员卡领取功能
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 publicfunctiongetSignPackage(){ $jsapiTicket=$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 publicfunctiongetHuiYuanSignPackage(){ $apiTicket=$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; }
详细代码说明:
HTML页面:
//引入微信js文件//配置信息验证接口(填写的js-sdk获取的签名包的参数) wx.config({ debug:false, appId:'', timestamp:'', nonceStr:'', signature:'', jsApiList:[ //所有要调用的API都要加到这个列表中 'addCard' ] }); wx.ready(function(){ //添加卡券 document.querySelector('#addCard').onclick=function(){ wx.addCard({ cardList:[ { cardId:"",//微信公众号内创建的会员卡的id cardExt:'{"timestamp":"","signature":""}'//会员卡的签名包 } ], //成功之后的回调的函数(通过回调函数该表数据库是否领取会员卡的状态) success:function(res){ $.ajax({ url:'__CONTROLLER__/editHuiYuan', type:'post', dataType:'json', data:{is_LingQu:'1',user_id:""}, success:function(){ $("#addCard").html("我的会员卡"); } }) } }); }; });
控制器中的代码:

publicfunctionindex(){ $user_id=session('user_id'); if($user_id){ $jssdk=new\Home\Model\WechatModel(); $signPackage=$jssdk->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(); }
