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;

}

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: '<?PHP echo $signPackage["appId"];?>',

timestamp: '<?php echo $signPackage["timestamp"];?>',

nonceStr: '<?php echo $signPackage["nonceStr"];?>',

signature: '<?php echo $signPackage["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":"<?php echo $huiyuanPackage['timestamp'] ?>","signature":"<?php echo $huiyuanPackage['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:"<?php echo $user['user_id'] ?>"},

success:function(){

$("#addCard").html("我的会员卡");

}

})

}

});

};

});

控制器中的代码：

类库：http://www.jb51.net/article/115732.htm

public function index(){

$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();

}
