Python Program: Observing urllib3 Response compression handling

Python urllib3 : Exercise-21 with Solution

Write a Python program that requests a server that supports response compression (gzip or deflate), and observe how urllib3 handles it.

Sample Solution:

Python Code :

import urllib3

# Create a PoolManager
http = urllib3.PoolManager()

# Define the URL of the server that supports response compression
url = 'https://httpbin.org/gzip'

try:
    # Make a GET request
    response = http.request('GET', url)

    # Check if the request was successful (status code 200)
    if response.status == 200:
        # Print the content of the response
        print("Response Content:")
        print(response.data.decode('utf-8'))
    else:
        print(f"Error: Unable to fetch data. Status Code: {response.status}")

except Exception as e:
    print(f"Error: {e}")

Sample Output:

Response Content:
{
  "gzipped": true, 
  "headers": {
    "Accept-Encoding": "identity", 
    "Host": "httpbin.org", 
    "User-Agent": "python-urllib3/1.26.16", 
    "X-Amzn-Trace-Id": "Root=1-65c39992-23574c3474d0f427038091a2"
  }, 
  "method": "GET", 
  "origin": "103.51.149.158"
}

Explanation:

In the above exercise,

• We import the urllib3 module.
• We create a PoolManager object to manage the connection pool for making HTTP requests.
• We define the URL of the server that supports response compression. Here, we use "https://httpbin.org/gzip", which is a server that responds with gzipped content.
• We make a GET request to the server using http.request('GET', url).
• We decode and print the content of the response if the request was successful.
