微信JS接口签名校验工具------------------------------------

access_token.json--------------------------------------------------
确保网站所在目录下有此文件，确保有权限读写
{"expire_time":1609213473,"access_token":"【这里是access_token】"}
jsapi_ticket.json--------------------------------------------------
确保网站所在目录下有此文件，确保有权限读写
{"expire_time":1609213473,"jsapi_ticket":"【这里是jsapi_ticket】"}
Controller页------------------------------
require_once "./Extend/jssdk.php" ;
$jssdk = new JSSDK('【appid 】','【secret】');//这里填写自己的appid 和secret
$signPackage = $jssdk->GetSignPackage();
$this->assign("signPackage",$signPackage);
View页--------------------------------------
<head>里加入<script type="text/javascript" src="https://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>，在其它JS调用之上
<script>
wx.config({

jsApiList: [
//我只调用了两个分享接口,分别是朋友圈和个人,大家有其它需要可以去文档中查找接口
'onMenuShareTimeline',
'onMenuShareAppMessage'
]
});
wx.ready(function () {
var shareData = {
title: '{$sitename}', // 标题
desc: '一起来测试吧', // 描述
link: 'http://www.xunteam.cn/hts/', // 分享的URL，必须和当前打开的网页的URL是一样的
imgUrl: 'http://xunteam.cn/hts/public/images/logo.png' // 缩略图地址
};
wx.onMenuShareAppMessage(shareData);
wx.onMenuShareTimeline(shareData);

wx.error(function (res) {
alert(res.errMsg);//错误提示
});
</script>
jssdk.php----------------如果遇到两个json文件不更新问题，请注意json_encode和json_decode的使用，可打印转换后的值看看是否有问题，哪个打出来没问题就用哪一个，再打印$res的值，如果有错误会提示错误信息，我的就是白名单问题，明明设置了服务器的IP，结果打印出来不是这个IP，说是没有在白名单，我把这个打印出来的IP加入了白名单就好了
