GoogleDrive利用api批量删除文件

2020-12-15 20:32:10 作者：互联网

由于之前用Google Colab做实验的时候误将图片解压到了根目录下，一共三万多个文件，一个个手动删除工作量太大，即使使用全选操作，由于网页端一次只能选中一页中所有的文件，也只有100个左右，所以搜索了大量的博客，最终只能选择使用Google官方提供的Api进行自动化，改造后的官方示例如下所示，注意要将CLIENT_ID和API_KEY修改成自己在谷歌api控制台申请的Application中获取到的（OAuth2和Api token两个地方要注意，具体申请步骤见官网）

此外要注意这个例子一次只能删除1000个文件，最笨的办法是手动刷新多次，也可自行改造js代码
注意需要使用python -m http.request 8000命令建立服务器后浏览器打开此html文件
注意需要浏览器kexue上网，否则api发不出去
注意Google Api官方Api次数限额，本人在debug的时候关注到官网有限额，虽然没有实际遇到限额问题
官网api文档比较全，可以自行参看
