简介

如果Github的项目太大，直接git clone可能下载到半路就中断了，导致反反复复下载不了。
这个时候应该咋办呢？
本人写了一个支持Github特定文件夹内容下载的项目：GitDown，github地址为：https://github.com/jmhIcoding/GitDown

目前已经公开的类似开源项目，经常会出现下载文件丢失的问题，或者代码年久失效。
我这个项目会自动记录下载失败的文件，对于未成功下载的文件会反复尝试下载。
2021年10月1日运行是完全正常的。

使用方法

安装

pip3 install gitdown

使用

gitdown -h
usage: gitdown [-h] --repo REPO --directory DIRECTORY --dst_root DST_ROOT
               [--thread_num THREAD_NUM]
Download github resposity directory.
optional arguments:
  -h, --help            show this help message and exit
  --repo REPO           Something like
                        https://github.com/jmhIcoding/social_webpage
  --directory DIRECTORY
                        Something like pcaps/. Note that do not start with "/"
                        and end with "/", use "" (empty) for root directory.
  --dst_root DST_ROOT   Indicate where do you want to store the downloaded
                        files and sub-dirs from github.
  --thread_num THREAD_NUM
                        The thread number for download!

一共有四个参数。

repo: 这个是给出仓库的url路径， 注意：仓库名的格式类似于https://github.com/jmhIcoding/social\_webpage，里面有用户名和仓库名。
directory：给出要从这个仓库里面待下载的文件夹，注意：目录名不能以“/” 开始和结束。 项目支持递归下载给定文件夹下的所有内容。
dst_root: 给出要将下载好的内容放置在何处
thread_num: 多线程下载的线程数，默认为 5

首次运行需要提供自己的github access token，因为项目运行需要能够访问你自己的github项目，因此需要此token，获取方式见：https://blog.csdn.net/jmh1996/article/details/109327334

Please input your github access token now, first time:1234

如果输入的token无效会报错，因此请按照教程自己申请github token。

Please input your github access token now, first time:1234

运行示例

例如，我要下载github里面用户jmhIcoding下的social_webpage项目的pcaps/weibo目录下的所有内容，这个命令为：

gitdown --repo=https://github.com/jmhIcoding/social_webpage --directory=pcaps/weibo --dst_root=./

运行过程：
