如何用requests优雅的下载图片?

requests下载图片太麻烦了,虽然urlretrieve可以一步搞定,但是我想统一使用requests库。
注释部分就是用requests写的。

from urllib.request import urlretrieve

import requests
from bs4 import BeautifulSoup

r = requests.get("http://www.pythonscraping.com")
bs = BeautifulSoup(r.text)
image = bs.find("a", {"id": "logo"}).find("img")["src"]

urlretrieve(image, "logo.jpg")

# ir = requests.get(image, stream=True)
# if ir.status_code == 200:
#     with open('logo.jpg', 'wb') as f:
#         for chunk in ir:
#             f.write(chunk)

    import requests
    from bs4 import BeautifulSoup
    
    r = requests.get("http://www.pythonscraping.com")
    bs = BeautifulSoup(r.text,'lxml')
    image = bs.find("a", {"id": "logo"}).find("img")["src"]
    
    ir = requests.get(image)
    if ir.status_code == 200:
        open('logo.jpg', 'wb').write(ir.content)
     

    或者用正则

    import re, requests
    
    r = requests.get("http://www.pythonscraping.com")
    p = re.compile(r'<a[^>]*?id="logo"[^<]*?<img[^>]*?src="([^"]*)')
    image = p.findall(r.text)[0]
    ir = requests.get(image)
    sz = open('logo.jpg', 'wb').write(ir.content)
    print('logo.jpg', sz,'bytes')
