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=$nonceStr&timestamp=$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");

}

})

}

});

};

});
