rem 你需要有github账号和具有gist权限的access_token;

rem 新建一个txt文件，复制全部代码，将上述的access_token填入代码中，重命名为.bat后缀的文件即可使用;

rem 按理说不限制上传文件大小，支持txt、yaml等文本文件，支持csv文件;

rem 要求所有文件的编码为utf8，否则会出现中文和符号乱码;

rem 实测win10自带的powershell版本5.1上传中文乱码，最好升级你的powershell版本到7+;

rem 确认你的powershell目录存在的是pwsh.exe还是powershell.exe，若是后者，将代码默认的pwsh替换成powershell。

rem 替换USER_NAME为你的GitHub用户名，用于拼接你的文件URL 
set USER_NAME=你的GitHub用户名

rem 替换YOUR_ACCESS_TOKEN为你的GitHub访问令牌
set TOKEN=YOUR_ACCESS_TOKEN

rem 设置上传到指定gist的gistId，不填此项则创建新的gist
set GIST_ID=

rem 设置上传后的Gist描述
set GIST_DESCRIPTION=你的Gist描述
