青书学堂看视频看课时 php 懒人版

上一篇关于青书学堂的操作起来有点麻烦

趁这几天有时间优化了一下

建议php 7.3 版本

(本程序会用到php里的curl 模块记得打开)

如果运行时获取信息空白(https 容易出现) 可以测试一下自己php的curl能不能正常用如果不能可以参考一下我的另一篇文章

SSL rtificate problem: unable to get local issuer certificate curl采集https数据采集不到-CSDN博客

只需要登录网页版青书学堂获取到请求的 cookie

把上面的cookie 改到文件里的第5行


<?php
// 需要改成自己的 
// 自己的 cookie 需要更改一下 具体可以查看 浏览器的请求头cookie ______________________________
// define('USER_COOKIE', '改成自己的');






// 当前学校索引 _____________
define('SCHOOL_INDEX', 0); // 默认第一个学校

// 查看的分钟数 建议 ________________
define('MINUTE', 60); // 分钟

// 当前学校 前缀
define('SCHOOL_PREFIX', getSchool());

// 获取学校
function getSchool() {

保存一下文件比如保存为 index.php 然后就可以了
