如何使用请求从Github下载和写入文件

让我们说有一个文件存在于github repo:

https://github.com/someguy/brilliant/blob/master/somefile.txt

我正在尝试使用请求来请求此文件,将其内容写入当前工作目录中的磁盘,稍后可以使用它。现在,我正在使用以下代码:

import requests
from os import getcwd

url = "https://github.com/someguy/brilliant/blob/master/somefile.txt"
directory = getcwd()
filename = directory + 'somefile.txt'
r = requests.get(url)

f = open(filename,'w')
f.write(r.content)

毫无疑问,丑陋,更重要的是,不工作。而不是预期的文本,我得到:

<!DOCTYPE html>

Hello future GitHubber! I bet you're here to remove those nasty inline styles,
DRY up these templates and make 'em nice and re-usable, right?

Please, don't. https://github.com/styleguide/templates/2.0

      .divider { border-top: 1px solid #d5d5d5; border-bottom: 1px solid #fafafa;}

      #parallax_wrapper {
        position: relative;
        z-index: 0;
      }
      #parallax_field {
        overflow: hidden;
        position: absolute;
        left: 0;
        top: 0;
        height: 370px;
        width: 100%;
      }

等等
来自Github的内容,但不是文件的内容。我做错了什么?

相关文件的内容在返回的数据中包含 。您将获得该文件的完整GitHub视图,而不仅仅是内容。

如果您要下载 该文件,则需要使用页面顶部的Raw链接,该链接将是(例如):

https://raw.github.com/someguy/brilliant/master/somefile.txt

请注意域名的更改,路径的blob/部分已消失。

使用requests GitHub存储库本身来证明这一点:

>>> import requests
>>> r = requests.get('https://github.com/kennethreitz/requests/blob/master/README.rst')
>>> 'Requests:' in r.text
True
>>> r.headers['Content-Type']
'text/html; charset=utf-8'
>>> r = requests.get('https://raw.github.com/kennethreitz/requests/master/README.rst')
>>> 'Requests:' in r.text
True
>>> r.headers['Content-Type']
'text/plain; charset=utf-8'
>>> print r.text
Requests: HTTP for Humans

答案 1 :(得分:5)

您需要从https://raw.github.com

请求文件的原始版本

看到区别:

https://raw.github.com/django/django/master/setup.pyhttps://github.com/django/django/blob/master/setup.py

此外,您应该在目录和文件名之间添加/

>>> getcwd()+'foo.txt'
'/Users/burhanfoo.txt'
>>> import os
>>> os.path.join(getcwd(),'foo.txt')
'/Users/burhan/foo.txt'

答案 2 :(得分:0)

就像更新一样,https://raw.github.com was migratedhttps://raw.githubusercontent.com。所以一般格式是:

url = "https://raw.githubusercontent.com/user/repo/branch/[subfolders]/file"

例如https://raw.githubusercontent.com/earnestt1234/seedir/master/setup.py。在 Martijn 的回答中仍然使用 requests.get(url)
