I have the same need for downloading images using requests.

We also set stream=True so that requests doesn't download the whole image into memory first. Note that you need to open the destination file in binary mode to ensure python doesn't try and translate newlines for you. 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: r = requests.get(settings.STATICMAP_URL.format(**data), stream=True) To iterate over the response use a loop iterating like this ensures that data is decompressed by this stage: r = requests.get(settings.STATICMAP_URL.format(**data), stream=True) R = requests.get(settings.STATICMAP_URL.format(**data), stream=True) You can then use pyfileobj() to have Python stream the data to a file object: import requests 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). To use the response.raw file-like object will not, by default, decode compressed responses (with GZIP or deflate). This article was first posted on my personal blog.You can either use the response.raw file object, or iterate over the response. Let me know of other tricks I might have overlooked. These are my 2 cents on downloading files using requests in Python.

The url-parsing code in conjuction with the above method to get filename from Content-Disposition header will work for most of the cases. In that case, the Content-Disposition header will contain the filename information.įilename = get_filename_from_cd(r.headers.get( 'content-disposition')) However, there are times when the filename information is not present in the url.Įxample, something like. This will be give the filename in some cases correctly. To extract the filename from the above URL we can write a routine which fetches the last string after backslash (/). We can parse the url to get the filename. So using the above function, we can skip downloading urls which don't link to media. If content_length and content_length > 2e8: # 200 mb approx return False content_length = header.get( 'content-length', None) To restrict download by file size, we can get the filesize from the Content-Length header and then do suitable comparisons. Return False return True print is_downloadable( '') Return False if 'html' in content_type.lower():

H = requests.head(url, allow_redirects= True)Ĭontent_type = header.get( 'content-type') import requestsĭoes the url contain a downloadable resource This allows us to skip downloading files which weren't meant to be downloaded. That way involved just fetching the headers of a url before actually downloading it. I looked into the requests documentation and found a better way to do it. So if the file is large, this will do nothing but waste bandwidth. It works but is not the optimum way to do so as it involves downloading the file for checking the header. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to.Ī naive way to do it will be - r = requests.get(url, allow_redirects= True) To solve this, what I did was inspecting the headers of the URL. When the URL linked to a webpage rather than a binary, I had to not download that file and just keep the link as is. This was one of the problems I faced in the Import module of Open Event where I had to download media from certain links. If you said that a HTML page will be downloaded, you are spot on.

What do you think will happen if the above code is used to download it ? Now let's take another example where url is. The above code will download the media at and save it as google.ico. Open( 'google.ico', 'wb').write(r.content) R = requests.get(url, allow_redirects= True)

I will write about methods to correctly download binaries from URLs and set their filenames. I will be using the god-send library requests for it. This post is about how to efficiently/correctly download files from URLs using Python.
