Python Redirect Handling and final URL example

Python urllib3 : Exercise-7 with Solution

Write a Python program to handle redirects and print the final response URL.

Sample Solution:

Python Code :

# Import the urllib3 library
 import urllib3

def handle_redirects():
    # Create a PoolManager instance
    http = urllib3.PoolManager()

    # Define the initial URL that may redirect
    initial_url = 'http://example.com'

        # Make a GET request with allow_redirects set to True
        response = http.request('GET', initial_url, redirect=True)

        # Check if the request was successful (status code 200)
        if response.status == 200:
            # Print the final response URL after following redirects
            print("Final Response URL:")
            # Print an error message if the request was not successful
            print(f"Error: Unable to fetch data. Status Code: {response.status}")

    except urllib3.exceptions.RequestError as e:
        print(f"Error: {e}")

if __name__ == "__main__":

Sample Output:

Final Response URL:


Here's a brief explanation of the above Python urllib3 library code:

  • Import Library:
    • urllib3: Used for handling HTTP requests.
  • Define Function handle_redirects:
    • Encapsulates the logic for a GET request with redirection handling.
  • Create a PoolManager Instance:
    • Initializes a urllib3.PoolManager() instance ('http') to manage HTTP connections.
  • Define Initial URL:
    • Specifies the initial URL ('initial_url') that may undergo redirects.
  • Make a GET Request with Redirects:
    • Uses http.request() to make a GET request to the initial URL with redirect=True to enable automatic following of redirects.
  • Check Response and Print Results:
    • Checks the HTTP status code of the response.
    • If the status code is 200, print the final response URL using response.geturl().
    • If not, print an error message with the status code.
  • Handle Exceptions:
    • Uses a try-except block to catch potential "urllib3" request-related exceptions.
    • Prints an error message if exceptions occur.
  • Run the Function:
    • Calls the handle_redirects() function when the script is executed.
