这篇文章主要介绍了微信公众号实现会员卡领取功能的相关资料,需要的朋友可以参考下
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;
}
详细代码说明：
HTML页面：
//引入微信js文件
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
<script type="text/JavaScript">
//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");
}
})
}
});
};
});
</script>
控制器中的代码：
类库：//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();
}
