  • thinkphp通过微信公众平台API自定义分享链接的标题、描述和缩略图(不会出现invalid signature签名无效的错误)

    获得access_token---------------------------------
    https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=【appid】&secret=【secret】

    获得ticket-------------------------------------------
    https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=【access_token】&type=jsapi

    微信JS接口签名校验工具------------------------------------
    https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign

    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({
    debug: false,
    appId: '{$signPackage["appId"]}',
    timestamp: '{$signPackage["timestamp"]}',
    nonceStr: '{$signPackage["nonceStr"]}',
    signature: '{$signPackage["signature"]}',
    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
