How to download image using requests – Stack Overflow
You can either use the file object, or iterate over the response.
To use the file-like object will not, by default, decode compressed responses (with GZIP or deflate). You can force it to decompress for you anyway by setting the decode_content attribute to True (requests sets it to False to control decoding itself). You can then use pyfileobj() to have Python stream the data to a file object:
import requests
import shutil
r = ((**data), stream=True)
if atus_code == 200:
with open(path, ‘wb’) as f:
= True
pyfileobj(, f)
To iterate over the response use a loop; iterating like this ensures that data is decompressed by this stage:
for chunk in r:
(chunk)
This’ll read the data in 128 byte chunks; if you feel another chunk size works better, use the er_content() method with a custom chunk size:
for chunk in er_content(1024):
Note that you need to open the destination file in binary mode to ensure python doesn’t try and translate newlines for you. We also set stream=True so that requests doesn’t download the whole image into memory first.
Download Image from URL using Python – jdhao’s blog
ContentsUsing urllib packageUsing requests packageDownloading large files with er_contentresponse. rawReferencesRecently, I want to download some images using Python. This is what I’ve
learned after native and naive way is to use
quest module to download an quest
url = ”
r = quest. urlopen(url)
with open(“”, “wb”) as f:
(())
However, the above code may error out with following HTTP Error 403: ForbiddenIn this case, we need to add a HTTP header to the request:import quest
# The following way works. Ref: req = quest(url, headers={‘User-Agent’: ‘Mozilla/5. 0’})
with quest. urlopen(req) as r:
A better way is to use requests
package. Here is a simple example to download an image using requests:import requests
r = (url)
(ntent)
Downloading large files with er_contentIn the above code, all content of the image will be read into memory at once.
If the image is large, it may consume too much ternatively, we can set stream parameter to True to stream request. In
this case, only the response header is downloaded. We can retrieve the image in
a whole using ntent1 or chunk by chunk by using
er_content method:# Using requests to download large files.
with (url, stream=True) as r:
for chunk in er_content(chunk_size=1024):
if chunk:
(chunk)
response. rawWhen stream is True, we can also use to stream the download.
is a file-like object. With the help of pyfileobj(),
we can save the image like this:# using
= True
pyfileobj(, f)
# or (())

Who is Who
Python provides different modules like urllib, requests etc to download files from the web. I am going to use the request library of python to efficiently download files from the ’s start a look at step by step procedure to download files using URLs using request library−1. Import moduleimport requests2. Get the link or urlurl = ”
r = (url, allow_redirects=True)3. Save the content with (”, ‘wb’)(ntent)save the file as requests
url = ”
r = (url, allow_redirects=True)
open(”, ‘wb’)(ntent)ResultWe can see the file is downloaded(icon) in our current working we may need to download different kind of files like image, text, video etc from the web. So let’s first get the type of data the url is linking to−>>> r = (url, allow_redirects=True)
>>> print(r. (‘content-type’))
image/pngHowever, there is a smarter way, which involved just fetching the headers of a url before actually downloading it. This allows us to skip downloading files which weren’t meant to be downloaded. >>> print(is_downloadable(”))
False
>>> print(is_downloadable(”))
TrueTo restrict the download by file size, we can get the filezie from the content-length header and then do as per our ntentLength = (‘content-length’, None)
if contentLength and contentLength > 2e8: # 200 mb approx
return FalseGet filename from an URLTo get the filename, we can parse the url. Below is a sample routine which fetches the last string after backslash(/) ”
if (‘/’):
print((‘/’, 1)[1]Above will give the filename of the url. However, there are many cases where filename information is not present in the url for example –. In such a case, we need to get the Content-Disposition header, which contains the filename requests
import re
def getFilename_fromCd(cd):
“””
Get filename from content-disposition
if not cd:
return None
fname = ndall(‘filename=(. +)’, cd)
if len(fname) == 0:
return fname[0]
filename = getFilename_fromCd(r. (‘content-disposition’))
open(filename, ‘wb’)(ntent)The above url-parsing code in conjunction with above program will give you filename from Content-Disposition header most of the time.
