response = requests.get(url)
response.content
response.text
一直在想requests的content和text属性的区别，从print 结果来看是没有任何区别的
@property
def text(self):
"""Content of the response, in unicode.
If Response.encoding is None, encoding will be guessed using
``chardet``.
The encoding of the response content is determined based solely on HTTP
headers, following RFC 2616 to the letter. If you can take advantage of
non-HTTP knowledge to make a better guess at the encoding, you should
set ``r.encoding`` appropriately before accessing this property.
"""
@property
def content(self):
"""Content of the response, in bytes."""
resp.text返回的是Unicode型的数据。
resp.content返回的是bytes型也就是二进制的数据
文本类型用text，图片、文件类型用contexnt
例子：保存抽屉的图片
import re
import requests
session = requests.session()
index = 1
try:
f = open('chouti.txt','r')
txt = f.read()
pattern = re.compile('http://(.*?).jpg',re.S)
items = re.findall(pattern, txt)
for item in items:
url = "http://" + item + ".jpg"
respone = session.get(url)
f1 = open(str(index)+".jpg", 'wb')
f1.write(respone.content)
f1.close()
index+=1
#context open文件要用wb，text open文件用w。
finally:
f.close()
