状态1：法定节假日 状态2：周末，但是因为调休而变更为工作日
如果只是想获取法定节日，可以用这个接口轻松获取2050年之前的信息 https://sp0.baidu.com/8aQDcjqpAAV3otqbppnN2DJv/api.php?query=%E6%B3%95%E5%AE%9A%E8%8A%82%E5%81%87%E6%97%A5&co=&resource_id=39042&t=1617089118959&ie=utf8&oe=gbk&cb=op_aladdin_callback&format=json&tn=wisetpl&cb=jQuery110203576901702188473_1617089118772&_=1617089118773  很简单，就不上代码了。但是这里只能获取法定节，无法获取法定休息日与调休。
法定休息日与调休一般是国务院在年末公布下一年的安排，所以下面的代码最多也只能获取下一年之前的信息

使用百度日历的接口~~使用的是百度的开放接口。与百度搜索日历后的页面数据一致。已作废~~
使用百度日历的接口
 查看工作台可以发现数据是从这个接口中获取的   比较可疑的是status这个参数，继续查看百度搜索页面源代码，大概在6000行左右可以发现处理日历的js源代码  格式化一下  很明显，status为1时为节假日，为2时就是改为工作日的休息日。通过观察得知这里面的参数与实际值是差一天的。剩下的代码就很容易了。
