function authenticate_o365

Maturity: 52

Authenticates with Microsoft Office 365 (O365) services by retrieving and returning an authentication token.

Complexity:
simple

Purpose

This function serves as an authentication wrapper for O365 API interactions. It retrieves an O365 authentication token by calling get_o365_token() and returns it for use in subsequent API calls. The function is designed to be a placeholder that can be extended with token refresh logic, secure token storage, and validation mechanisms. It acts as a centralized authentication point for O365 service integrations.

Source Code

def authenticate_o365() -> None:
    """
    Authenticate with O365 and ensure the token is valid.
    This function can be expanded to handle token refresh logic if needed.
    """
    token = get_o365_token()
    # Store the token securely or use it for subsequent API calls
    # This is a placeholder for further implementation
    return token

Return Value

Type: None

Despite the type hint indicating 'None', the function actually returns a token object (likely a string or dict) obtained from get_o365_token(). The exact type depends on the implementation of get_o365_token(). Note: There is a discrepancy between the type hint (None) and the actual return statement (token), which should be corrected in production code.

Dependencies

  • requests
  • typing

Required Imports

from typing import Dict
from typing import Any
import requests
from requests.exceptions import RequestException
from CDocs.config import settings

Usage Example

# Assuming get_o365_token() is defined elsewhere
# from your_module import authenticate_o365

# Authenticate and get token
token = authenticate_o365()

# Use the token for O365 API calls
headers = {
    'Authorization': f'Bearer {token}',
    'Content-Type': 'application/json'
}

# Example API call with the token
import requests
response = requests.get(
    'https://graph.microsoft.com/v1.0/me',
    headers=headers
)

if response.status_code == 200:
    user_data = response.json()
    print(f"Authenticated as: {user_data.get('displayName')}")

Best Practices

  • Fix the return type hint to match the actual return value (should be the token type, not None)
  • Implement proper error handling for authentication failures
  • Add token validation logic to ensure the token is not expired before returning
  • Implement secure token storage mechanism (e.g., encrypted storage, secure memory)
  • Add token refresh logic to automatically renew expired tokens
  • Consider implementing a token caching mechanism to avoid unnecessary authentication calls
  • Add logging for authentication events for security auditing
  • Ensure the get_o365_token() function is properly defined and handles exceptions
  • Consider making this function return a structured object with token metadata (expiry time, scope, etc.)
  • Implement rate limiting to prevent authentication throttling by O365 services
