如何使用请求从Github下载和写入文件 [英] How to download and write a file from Github using Requests
问题描述
让我们说有一个文件保存在github仓库中:
Lets say there's a file that lives at the 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，并将其内容写入当前工作目录中的磁盘，以供以后使用.现在，我正在使用以下代码:
I'm trying to use requests to request this file, write the content of it to disk in the current working directory where it can be used later. Right now, I'm using the following code:
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)
无疑是丑陋的，更重要的是，它不起作用.而不是预期的文本，我得到:
Undoubtedly ugly, and more importantly, not working. Instead of the expected text, I get:
<!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_field {
overflow: hidden;
position: absolute;

top: 0;
height: 370px;
width: 100%;
}
等等等.
来自Github的内容，但不包含文件的内容.我在做什么错了?
etc etc.
Content from Github, but not the content of the file. What am I doing wrong?
推荐答案
问题文件的内容包含在返回的数据中.您将获得该文件的完整GitHub视图，而不仅仅是内容.
The content of the file in question is included in the returned data. You are getting the full GitHub view of that file, not just the contents.
如果要下载 just 文件，则需要使用页面顶部的Raw链接，该链接为(例如):
If you want to download just the file, you need to use the Raw link at the top of the page, which will be (for your example):
https://raw.github.com/someguy/brilliant/master/somefile.txt
请注意域名更改，路径的blob/部分消失了.
Note the change in domain name, and the blob/ part of the path is gone.
要通过requests GitHub存储库本身对此进行演示:
To demonstrate this with the requests GitHub repository itself:
>>> 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
