How would you design error handling in a RESTful API to ensure it provides clear and useful error messages?
- Use generic error messages to hide sensitive information.
- Return appropriate HTTP status codes and include error details in the response body.
- Log all errors on the server and return a generic error message to the client.
- Return 404 Not Found for all errors to prevent information leakage.
Designing effective error handling in a RESTful API is essential for a good developer and user experience. Returning appropriate HTTP status codes (e.g., 400 for bad requests, 401 for unauthorized access, 404 for not found, etc.) and including detailed error information in the response body (e.g., error codes, descriptions, and possible solutions) helps clients understand and handle errors effectively. Hiding sensitive information is vital, but using generic error messages should be avoided to aid troubleshooting. This approach ensures clear and useful error messages for both developers and API users.
