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

pyfileobj(, f)
# or (())

We split the Image URL using forward-slash( /) and then use [-1] to slice the last lename = (“/”)[-1]The get() method from the requests module will be used to retrieve the image. r = (image_url, stream = True)Use stream = True to guarantee no, we will create the file locally in binary-write mode and use the copyfileobj() method to write our image to the file. # Set decode_content value to True, otherwise the downloaded image file’s size will be = True# Open a local file with wb ( write binary) open(filename, ‘wb’) as f: pyfileobj(, f)We can also add certain conditionals to check if the image was retrieved successfully using Request’s Status can also improve further by adding progress bars while downloading large files or a large number of files.

Some programs can attack the server by sending a large number of requests. This prevents the server from is why these websites can either:Block you and you will receive HTTP Error you different or NULL can overcome this by modifying user-agent, a variable sent with our request. This variable, by default, tells the website that the visitor is a python modifying this variable, we can act as if the website is being accessed on a standard web browser by a normal can read more about it here.
