How to use Python Requests with Basic Authentication

If you want to access a HTTP resource that requires authentication using Python Requests library, you can use the built-in support for Basic Authentication. Basic Authentication is a simple authentication scheme that requires a username and password to be sent in the HTTP headers with every request.

Using Requests with Basic Authentication

To use Requests with Basic Authentication, you need to pass a tuple of (username, password) to the auth parameter of the requests.get() or requests.post() method. Here's an example:


      import requests

      url = 'http://example.com/api/something'
      username = 'myusername'
      password = 'mypassword'

      response = requests.get(url, auth=(username, password))

      print(response.text)

This code sends a GET request to the URL 'http://example.com/api/something' with the Basic Authentication headers included in the request. Replace 'myusername' and 'mypassword' with your actual credentials.

Other Ways to Use Basic Authentication

You can also pass a requests.auth.HTTPBasicAuth object instead of a tuple. This can be useful if you want to reuse the same authentication object for multiple requests:


      import requests
      from requests.auth import HTTPBasicAuth

      url = 'http://example.com/api/something'
      username = 'myusername'
      password = 'mypassword'

      auth = HTTPBasicAuth(username, password)

      response1 = requests.get(url, auth=auth)
      response2 = requests.get(url, auth=auth)

      print(response1.text)
      print(response2.text)

You can also specify the authentication headers directly in the headers parameter:


      import requests

      url = 'http://example.com/api/something'
      username = 'myusername'
      password = 'mypassword'

      headers = {'Authorization': 'Basic ' + b64encode((username + ':' + password).encode()).decode()}

      response = requests.get(url, headers=headers)

      print(response.text)

This code sends a GET request to the URL 'http://example.com/api/something' with the Basic Authentication headers included in the request. The username and password are concatenated with a colon, base64 encoded and included in the Authorization header.
