Simple URL GET/POST function in Python

Simple URL GET/POST function in Python

To perform simple HTTP GET and POST requests in Python, you can use the requests library, which is a popular and user-friendly library for making HTTP requests. You can install it using pip if you haven't already:

pip install requests

Here are examples of how to perform GET and POST requests using the requests library:

HTTP GET Request:

import requests # URL to perform a GET request to url = "https://example.com" # Send a GET request response = requests.get(url) # Check if the request was successful (status code 200) if response.status_code == 200: print("GET request successful") print("Response content:") print(response.text) else: print(f"GET request failed with status code {response.status_code}")

HTTP POST Request:

import requests # URL to perform a POST request to url = "https://example.com/api" # Data to send in the POST request (as a dictionary) data = {"key1": "value1", "key2": "value2"} # Send a POST request with data response = requests.post(url, data=data) # Check if the request was successful (status code 200) if response.status_code == 200: print("POST request successful") print("Response content:") print(response.text) else: print(f"POST request failed with status code {response.status_code}")

In these examples:

  • We import the requests library.

  • For the GET request, we use requests.get() and specify the URL to make the request to. We check the response status code to determine if the request was successful and print the response content.

  • For the POST request, we use requests.post() and specify the URL and data to send in the request. Again, we check the response status code and print the response content.

You should replace the URLs and data with your specific endpoints and data. Additionally, you can add error handling and handle different response codes according to your application's needs.

    • Description: Demonstrates how to include custom HTTP headers in a GET request.
    • Code:
      import requests url = 'https://jsonplaceholder.typicode.com/posts/1' # Example URL headers = {'User-Agent': 'MyPythonApp/1.0'} # Custom HTTP headers response = requests.get(url, headers=headers) # Perform a GET request with headers print(response.status_code) # Output the HTTP status code print(response.json()) # Output the response body as JSON

  5. Sending form data with an HTTP POST request

    • Description: This example shows how to send form data (application/x-www-form-urlencoded) with an HTTP POST request.
    • Code:
      import requests url = 'https://httpbin.org/post' # Example URL form_data = {'name': 'John Doe', 'email': 'john.doe@example.com'} # Form data response = requests.post(url, data=form_data) # Perform a POST request with form data print(response.status_code) # Output the HTTP status code print(response.json()) # Output the response body

  6. Sending a file with an HTTP POST request in Python

    • Description: Illustrates how to upload a file using an HTTP POST request in Python.
    • Code:
      import requests url = 'https://httpbin.org/post' # Example URL for testing files = {'file': ('example.txt', open('example.txt', 'rb'))} # File to upload response = requests.post(url, files=files) # Perform a POST request with a file print(response.status_code) # Output the HTTP status code print(response.json()) # Output the response body

  7. Handling HTTP errors in Python GET/POST requests

    • Description: Demonstrates how to handle HTTP errors (e.g., 404, 500) when performing GET/POST requests.
    • Code:
      import requests try: response = requests.get('https://jsonplaceholder.typicode.com/invalid-endpoint') # Invalid URL response.raise_for_status() # Raise an exception if HTTP status is an error except requests.exceptions.HTTPError as err: print(f"HTTP error occurred: {err}") # Handle HTTP error except Exception as err: print(f"An error occurred: {err}") # Handle other exceptions

  8. Setting a timeout for HTTP GET/POST requests in Python

    • Description: Shows how to set a timeout to prevent long-running HTTP requests.
    • Code:
      import requests try: response = requests.get('https://jsonplaceholder.typicode.com/posts/1', timeout=2) # 2-second timeout response.raise_for_status() print(response.json()) # Output the response body as JSON except requests.exceptions.Timeout: print("The request timed out") # Handle timeout except Exception as err: print(f"An error occurred: {err}")

  9. Sending HTTP GET/POST requests with Basic Authentication in Python

    • Description: Demonstrates how to use Basic Authentication to send GET/POST requests.
