Requests is a versatile HTTP library in python with various applications. One of its applications is to download a file from web using the file URL.
Installation: First of all, you would need to download the requests library. You can directly install it using pip by typing following command:

Or download it directly from here and install manually.

To download the image for the link, you may want to look into “Bulk Image Downloaders”. Inspired by this inquires, I decided to make a “top 5 bulk image downloader” list for you. Be sure to check out this article if you want to download images from links.

Downloading files

importrequests

image_url ='https://www.python.org/static/community_logos/python-logo-master-v3-TM.png'

# URL of the image to be downloaded is defined as image_url

r =requests.get(image_url) # create HTTP response object

# send a HTTP request to the server and save

# the HTTP response in a response object called r

# binary format

# write the contents of the response (r.content)

f.write(r.content)

This small piece of code written above will download the following image from the web. Now check your local directory(the folder where this script resides), and you will find this image:

All we need is the URL of the image source. (You can get the URL of image source by right-clicking on the image and selecting the View Image option.)

Download large files

The HTTP response content (r.content) is nothing but a string which is storing the file data. So, it won’t be possible to save all the data in a single string in case of large files. To overcome this problem, we do some changes to our program:

Since all file data can’t be stored by a single string, we use r.iter_content method to load data in chunks, specifying the chunk size.

Setting stream parameter to True will cause the download of response headers only and the connection remains open. This avoids reading the content all at once into memory for large responses. A fixed chunk will be loaded each time while r.iter_content is iterated.

Here is an example:

file_url ='http://codex.cs.yale.edu/avi/db-book/db4/slide-dir/ch1-2.pdf'

r =requests.get(file_url, stream =True)

with open('python.pdf','wb') as pdf:

ifchunk:

Downloading Videos

In this example, we are interested in downloading all the video lectures available on this web-page. All the archives of this lecture are available here. So, we first scrape the webpage to extract all video links and then download the videos one by one.

frombs4 importBeautifulSoup

''

URL of the archive web-page which provides link to

download each video manually.

In this example, we first crawl the webpage to extract

''

# specify the URL of the archive here

archive_url ='http://www-personal.umich.edu/~csev/books/py4inf/media/'

defget_video_links():

# create response object

soup =BeautifulSoup(r.content,'html5lib')

# find all links on web-page

video_links =[archive_url +link['href'] forlink inlinks iflink['href'].endswith('mp4')]

returnvideo_links

and download them one by one''

# obtain filename by splitting url and getting

file_name =link.split('/')[-1]

print'Downloading file:%s'%file_name

# create response object

with open(file_name, 'wb') as f:

forchunk inr.iter_content(chunk_size =1024*1024):

f.write(chunk)

print'%s downloaded!n'%file_name

print'All videos downloaded!'

if__name__ =='__main__':

# getting all video links

download_video_series(video_links)

Advantages of using Requests library to download web files are:

One can easily download the web directories by iterating recursively through the website!
This is a browser-independent method and much faster!
One can simply scrape a web page to get all the file URLs on a webpage and hence, download all files in a single command-
