How to Use Python Requests

As someone who has worked with Python for a few years now, I can tell you that the requests library is one of the most useful tools to have at your disposal. It makes sending HTTP requests a breeze and can be used for a wide variety of tasks such as web scraping, API requests, and more. Here's a brief overview of how to use Python requests:

Installation

Before you can start using Requests, you'll need to install it. You can do this using pip, the Python package manager:


      pip install requests

GET Requests

The most common type of request is a GET request, which retrieves data from a server. Here's an example:


      import requests
      
      response = requests.get('https://www.example.com')
      
      print(response.text)
  • The requests library is imported.
  • A GET request is made to 'https://www.example.com'.
  • The response is stored in the 'response' variable.
  • The response text is printed.

POST Requests

POST requests are used to send data to a server. Here's an example:


      import requests
      
      payload = {'key1': 'value1', 'key2': 'value2'}
      
      response = requests.post('https://www.example.com/post', data=payload)
      
      print(response.text)
  • The requests library is imported.
  • A dictionary 'payload' is created with the data to be sent.
  • A POST request is made to 'https://www.example.com/post' with the data from the 'payload' dictionary.
  • The response is stored in the 'response' variable.
  • The response text is printed.

Headers

You can add headers to your requests by passing a dictionary to the 'headers' parameter:


      import requests
      
      headers = {'User-Agent': 'Mozilla/5.0'}
      
      response = requests.get('https://www.example.com', headers=headers)
      
      print(response.text)
  • The requests library is imported.
  • A dictionary 'headers' is created with the User-Agent header set to Mozilla/5.0.
  • A GET request is made to 'https://www.example.com' with the headers from the 'headers' dictionary.
  • The response is stored in the 'response' variable.
  • The response text is printed.

Authentication

If you need to authenticate your requests, you can do so by passing your credentials to the 'auth' parameter:


      import requests
      
      response = requests.get('https://api.github.com/user', auth=('user', 'pass'))
      
      print(response.json())
  • The requests library is imported.
  • A GET request is made to 'https://api.github.com/user' with the authentication details passed to the 'auth' parameter.
  • The response is stored in the 'response' variable.
  • The response JSON is printed.
