It took 3.149 seconds to download 25 random images for the asynchronous version of the script. The coroutine make_request() makes the GET request, awaits the response, and saves the downloaded image if the status of the response is 200. The requests are made using a single session to reuse the session’s internal connection pool. It uses a single ClientSession and a task is created for each image that is being downloaded. The coroutine bulk_request() serves as the main entry point into the script’s chain of coroutines. Next, we will iterate through the imagelinks list and download each image: for link in imagelinks: filename link.split ('/') -1. In this step we will use the image links we found in the above steps to download and save the images. Resp = await session.request(method="GET", url=url)Īsync with aiofiles.open(path, 'wb') as f: Download Images from a Web Page using Python. The asynchronous version of our script will look like this in the simplest version: import asyncio It allows to read and save files in a non-blocking manner. aiofiles is a library for handling local disk files in asyncio applications.

So our program will be executed in less time than its synchronous version because while we are waiting for a response from the server we can send another concurrent request which starts downloading the second image and so on.įirst, we will need to install the required packages: pip install aiohttp aiofilesĪlso, we need aiofiles package to save images on the local filesystem. It allows us to send multiple requests asynchronously to the image resource's server ( ).

It's blazingly fast asynchronous HTTP Client/Server for asyncio and Python. Next, we will rewrite our program to use aiohttp library. On my laptop, it took approximately 33.983 seconds.

url attribute.Īlso, we track the time to measure how much time it takes to download and save 25 images from the resource. When we send a request to the URL above it will redirect us to another URL like. Also, unique names will be given to images using function uuid4(). To extract the file extension we use packages os, urllib. images) keeping the downloaded image's extension.

Let’s take a look at the full program: import osĮxtension = os.path.splitext(parse.urlsplit(response.url).path)Īs you can see the preceding script will download 25 images with defined sizes and saves them on the local file system (. It will install the latest version of the package. It is not in Python's standard library, so first, we will need to install it.Īctivate your virtual environment and enter pip install requests. Our first script will use Python's the most popular package for HTTP requests: requests package. So our URL will be Using requests package In this script, we will get images with sizes 370x250 px. This resource allows downloading images with specified sizes. So it seems that the file is uncompleted, but I don’t know why python cannot completely download it.In this tutorial, we will write a simple Python program that downloads random images from a resource called. The size of the former one is several byte smaller. I compare the image that I download by Python and the one that I download manually through the browser. The Preview says “It may be damaged or use a file format that Preview doesn’t recognize.”

This URL is valid and I can save it through the browser but the python code would download a file that cannot be opened. # urllib.urlretrieve(self.url, filePath) with open(filePath, 'wb') as localFile: The code is as follow def downloadImage( self):įilePath = localSaveRoot + self.catalog + self.fileName + Picture.postfix However, when I use python to download the image, the file cannot be opened. import requests def downloadimage (url, filename, headers): Send GET request response requests.get (url, headersheaders) If the HTTP request has been successfully completed, we should receive Response code 200 (you can learn more about response codes here ). I could download it manually using the explorer. I got a problem when I am using python to save an image from url either by urllib2 request or urllib.urlretrieve.
