When downloading content from a URL, we often want to save it in a file. Parsing a URL with urllib to get the filename We will examine parsing of URLs for filenames next. This class will be used for other tasks such as determining content types, filename, and extensions for those files.

The code then simply reports on the length of that data, with the value of 171014. That data can then be retrieved using the data property: data(self): This function uses urlopen to get a response object, and then reads the stream and stores it as a property of the object. The following is the code of the read() method: def read(self): The constructor stores the URL, parses it, and downloads the file with the read() method. """ Construct the object, parse the URL, and download now if The constructor of the URLUtility class has the following implementation: def _init_(self, url, readNow=True): The URL is defined as a constant const.ApodEclipseImage() in the const module: def ApodEclipseImage():

The URLUtility class can download content from a URL.Also, the example for this recipe is in the 04/01_download_image.py file. Make sure the modules folder is in your Python path. We will be using this class in this recipe and a few others.

This class handles several of the scenarios in this chapter with downloading and parsing URLs. There is a class named URLUtility in the urls.py module in the util folder of the solution. Downloading media content from the webĭownloading media content from the web is a simple process: use Requests or another library and download it just like you would HTML content. It’s a simple step from there to also transcode video with ffmpeg.

We won’t look at video transcoding, but we will rip MP3 audio out of an MP4 file using ffmpeg. Another scenario is to extract only the audio from a video file. Many times these are used on a new website as thumbnail links to the scraped media which is stored locally.įinally, it is often the need to be able to transcode media, such as converting non-MP4 videos to MP4, or changing the bit-rate or resolution of a video.

We will examine several techniques of how to generate thumbnails and make website page screenshots. Hence, we will learn how to download and correctly represent the media type based on information from the web server.Īnother common task is the generation of thumbnails of images, videos, or even a page of a website. To store the content locally (or in a service like S3) and to do it correctly, we need to know what is the type of media, and it isn’t enough to trust the file extension in the URL. This media can include images, audio, and video. This book contains step by step tutorials on how to leverage Python programming techniques for ethical web scraping.Ī common practice in scraping is the download, storage, and further processing of media content (non-web pages or data files). Our article is an excerpt from the book Web Scraping with Python, written by Richard Lawson.
