使用请求下载图像 url 问题

Question

I use this code to download image:

import shutil
import requests
url = 'https://cdn.pixabay.com/photo/2017/09/25/11/55/cyberspace-2784907__340.jpg'

response = requests.get(url, stream=True)
with open('img.png', 'wb') as out_file:
    shutil.copyfileobj(response.raw, out_file)
del response

and it works. But when i use this type of link it dont work:

if i put it in a web explorer, it shows, what is the best way to approach this?

I don't get an error when the image is downloaded, the file just says is not supported and i cannot get it to open in windows:

The link works: the link to image

Answer 1

Maybe you should try to add

response.raw.decode_content = True

before

shutil.copyfileobj(response.raw, out_file)

If it does not work, could you please specify your problem and add correct "non-working" image URL?

Answer 2

The image may not be png image. Check the first few bytes to see if it is png or jpeg or anything else.

png: 89 50 4E 47 0D 0A 1A 0A

jpeg: FF D8 FF E0 00 10 4A 46 49 46 00 01 or FF D8 FF EE or FF D8 FF E1?? ?? 45 78 69 66 00 00 FF D8 FF E1?? ?? 45 78 69 66 00 00

bmp: 42 4D

webp: 52 49 46 46?? ?? ?? ?? 57 45 42 50 52 49 46 46?? ?? ?? ?? 57 45 42 50

where question marks ( ?? ) are random bytes.
