https://cloud.tencent.com/developer/article/1449884 还有这节,,需要参考

首先说一下,这两个地方需要配置一样

网站根目录建个文件夹 airkiss的文件夹

里面放上

index.php

<?php
require_once "jssdk.php";
$jssdk = new JSSDK("yourAppID", "yourAppSecret");//这里改成自己的
$signPackage = $jssdk->GetSignPackage();
?>

access_token.php

<?php exit();?>{"access_token":"24_w2RYneHczb89fnIljshdF4hPjLKrFmvpLLCQT5zFHqlE0kOPCmVt37jgdBHPxYmPQh27Ga4kpy1HwUu8rppnFZyaytsTSTEwwfUkwrv6Sqy3cN__3tkHspqi7EIGHVgAJAPQE","expire_time":1565759510}

然后
