在Python中将二进制流保存为文件的三种办法。第一种使用Image包，第二种使用分片写方法，第三种直接全部写。

coding=utf-8

import requests;

from PIL import Image;

from io import BytesIO;

path="";

r=requests.get(path);

def test_io():

i=Image.open(BytesIO(r.content));

i.save("2.jpg");

def test_request():

with open("12.jpg","wb") as fd:

for chunk in r.iter_content(chunk_size=1024):

fd.write(chunk);

def test_request1():

with open("3.jpg","wb") as f:

f.write(r.content);

test_request1();
