.NET Core Microservices - Cart Controller and Service for Applying or Removing Coupon

The video tutorial explains how to add and implement action methods in a card controller and cart service. It covers the process of creating 'apply coupon' and 'remove coupon' methods, integrating them into the cart service, and then using these methods in the cart controller. The tutorial emphasizes the importance of correctly handling user IDs and access tokens, and ensuring that the methods are asynchronous. The implementation is verified by redirecting responses and handling null cases appropriately.

What is the purpose of adding an action name in the card controller?

• To update the CART index

• To modify the card DTO

• To change the HTTP method type

• To ensure the method is called correctly

In the CART service, what is required to apply a coupon?

• Only a user ID

• A card DTO

• An access token

• A response DTO

What is the main focus when implementing the remove coupon method in the CART service?

• Handling card DTO

• Ensuring no spelling mistakes

• Updating the CART index

• Using an access token

What is the first step when integrating the apply coupon method in the CART controller?

• Getting the user ID and access token

• Copying everything from remove coupon

• Redirecting to the CART index

• Returning a null response

What happens if the response from the apply coupon method is null?

• The user is redirected to the CART index

• The method is called again

• The view is returned

• An error message is displayed
