Maturity: 44

Purpose

This function provides a safe way to load OneDrive configuration settings from a JSON file. It handles cases where the file doesn't exist or cannot be parsed, returning an empty dictionary as a fallback. This is typically used to load authentication credentials, API endpoints, or other OneDrive-related settings needed for cloud integration.

Source Code

def load_onedrive_config(config_file: str = None) -> dict:
    """Load OneDrive configuration from file"""
    if config_file and Path(config_file).exists():
        try:
            with open(config_file, 'r') as f:
                return json.load(f)
        except Exception as e:
            print(f"⚠️  Warning: Could not load OneDrive config from {config_file}: {e}")
    return {}

Parameters

Name Type Default Kind
config_file str None positional_or_keyword

Parameter Details

config_file: Optional string path to the JSON configuration file containing OneDrive settings. If None or if the file doesn't exist, the function returns an empty dictionary. Expected to be a valid file path string pointing to a JSON file with OneDrive configuration parameters.

Return Value

Type: dict

Returns a dictionary containing the OneDrive configuration loaded from the JSON file. If the file doesn't exist, cannot be read, or contains invalid JSON, returns an empty dictionary {}. The structure of the returned dictionary depends on the contents of the configuration file.

Dependencies

  • json
  • pathlib

Required Imports

import json
from pathlib import Path

Usage Example

import json
from pathlib import Path

def load_onedrive_config(config_file: str = None) -> dict:
    """Load OneDrive configuration from file"""
    if config_file and Path(config_file).exists():
        try:
            with open(config_file, 'r') as f:
                return json.load(f)
        except Exception as e:
            print(f"⚠️  Warning: Could not load OneDrive config from {config_file}: {e}")
    return {}

# Example usage:
# Load config from a specific file
config = load_onedrive_config('onedrive_config.json')
print(config)

# Load with no file specified (returns empty dict)
config = load_onedrive_config()
print(config)  # Output: {}

# Load from non-existent file (returns empty dict with no error)
config = load_onedrive_config('nonexistent.json')
print(config)  # Output: {}

Best Practices

  • Always check if the returned dictionary is empty before using configuration values
  • The function silently handles errors and returns an empty dict, so implement additional validation if specific config keys are required
  • Consider logging or handling the warning message appropriately in production environments
  • Ensure the JSON file has proper read permissions before calling this function
  • The function uses Path.exists() which only checks file existence, not whether it's readable or valid JSON
  • This function is designed to be fault-tolerant, making it safe to call even with invalid or missing file paths
