Building a RESTful API with Flask : Error Handling, Authentication, and File Handling with Public and Admin Routes
In this mid-project, we built a RESTful API using Flask, implementing comprehensive error handling, user authentication, and file handling capabilities. The API includes two route types: public routes, accessible without authentication, and protected admin routes that require secure authentication. Through this project, we developed a robust API structure that effectively manages errors, ensures secure user access, and supports file uploads.
