python3 requests的content和text方法

text返回的是Unicode型的数据

content返回的是是二进制的数据。

也就是说，如果你想取文本，可以通过r.text。

如果想取图片，文件，则可以通过r.content

>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.text
'{"message":"Hello there, wayfaring stranger. If you’re reading this then you probably didn’t see our blog post a couple of years back announcing that this API would go away: http://git.io/17AROg Fear not, you should be able to get what you need from the shiny new Events API instead.","documentation_url":"https://developer.github.com/v3/activity/events/#list-public-events"}'
>>> r.content
b'{"message":"Hello there, wayfaring stranger. If you\xe2\x80\x99re reading this then you probably didn\xe2\x80\x99t see our blog post a couple of years back announcing that this API would go away: http://git.io/17AROg Fear not, you should be able to get what you need from the shiny new Events API instead.","documentation_url":"https://developer.github.com/v3/activity/events/#list-public-events"}'

例子：

import requests
r = requests.get('http://img2.niutuku.com/1312/0804/0804-niutuku.com-27840.jpg')

with open('demo1.jpg', 'wb') as fp:
