Web API Development with Flask (Video 9)

This video tutorial covers the implementation of CRUD operations, focusing on the 'read' operation using HTTP GET requests in RESTful APIs. It explains the configuration of API routes for candidate entities, the role of middleware, and the data provider service. The tutorial also demonstrates testing API responses using Postman. Finally, it summarizes the CRUD operations discussed and previews upcoming topics like update, delete, hypermedia, and pagination.

What is a key characteristic of the 'read' operation in RESTful APIs?

• It modifies the underlying data.

• It uses HTTP POST requests.

• It requires user authentication.

• It should be idempotent.

In the context of API routes, what is the purpose of the 'get' method?

• To update a resource.

• To delete a resource.

• To create a new resource.

• To retrieve a resource.

What happens if a requested candidate is not found in the database?

• A new candidate is created.

• A default candidate is returned.

• The request is ignored.

• An HTTP 404 error is returned.

Which tool is used in the video to demonstrate the 'read' operation?

• MySQL Workbench

• Postman

• GitHub

• Visual Studio Code

What is the next step after implementing 'create' and 'read' operations?

• Implementing 'delete' operation

• Implementing 'update' and 'delete' operations

• Adding user authentication

• Integrating with a third-party API
