Python GET Request with Timeout example

Python urllib3 : Exercise-5 with Solution

Write a Python program that sets a timeout for a GET request to handle cases where the server takes too long to respond.

Sample Solution:

Python Code :

# Import the urllib3 library
 import urllib3

def make_get_request_with_timeout():
    # Create a PoolManager instance with a timeout of 5 seconds
    http = urllib3.PoolManager(timeout=5)

    # Define the API endpoint URL
    api_url = 'https://jsonplaceholder.typicode.com/posts/1'

    try:
        # Make a GET request with the specified timeout
        response = http.request('GET', api_url)

        # Check if the request was successful (status code 200)
        if response.status == 200:
            # Print the response data
            print("GET Request Successful:")
            print(response.data.decode('utf-8'))
        else:
            # Print an error message if the request was not successful
            print(f"Error: Unable to make GET request. Status Code: {response.status}")

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

if __name__ == "__main__":
    make_get_request_with_timeout()

Sample Output:

GET Request Successful:
{
  "userId": 1,
  "id": 1,
  "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
  "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto"
}

Explanation:

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

• Import Library:
• urllib3: Used for handling HTTP requests.
• Define Function make_get_request_with_timeout:
• Encapsulates the logic for making a GET request with a specified timeout.
• Create a PoolManager Instance with Timeout:
• Initializes a urllib3.PoolManager() instance (http) with a 5 second timeout.
• Define API Endpoint:
• Specifies the API endpoint URL (api_url) for the GET request.
• Make a GET Request with Timeout:
• Uses http.request() to send a GET request to the API with the specified timeout.
• Check Response and Print Results:
• Check the HTTP status code of the response.
• If the status code is 200, print the response data.
• If not, print an error message with the status code.
• Handle Exceptions:
• Uses a try-except block to catch potential "urllib3" request-related exceptions, such as timeouts.
• Prints an error message if exceptions occur.
• Run the Function:
• Calls the make_get_request_with_timeout() function when the script is executed.
