Sometimes when you scrape a website, you may have encountered the fact that the website returns shortened URLs to sources from other websites.
As in this case, for example, https://upflix.pl/r/Qb64Ar this link consists of a domain and some random characters. The way a shortened link works is that it redirects you to another page. Therefore, the status_code that our query returns is 302
Sometimes it happens that we need a full URL to get that can do this with a few lines of Python code and the requests library.
pip install requests
We will use the head method to perform this function
This method is similar to get with the difference that it does not return any content, only headers.
response = requests.head(short_url)
After executing the query, we can check the headers that were returned.
There is information here such as:
- date
- type of website content
- character encoding
- FULL LINK
and many other information you can see below.
