Building Microservices API in Go - Auth Server: Verify API

This video tutorial covers the implementation of authorization in a service using middleware. It explains how to verify tokens and manage role-based access control without altering existing code. The tutorial demonstrates creating middleware with Gorilla Mux, defining an authorization matrix, and testing access. It also includes a detailed walkthrough of the auth middleware and the verification process using JWT tokens.

What is the primary role of middleware in a web service?

• To manage user interface

• To handle database operations

• To process requests and responses

• To generate reports

How does middleware contribute to role-based access control?

• By storing user data

• By managing server resources

• By verifying tokens and claims

• By designing user interfaces

What library is used to create middleware in the video?

• Gorilla Mux

• Flask

• Django

• Express.js

What is the purpose of the 'next' function in middleware?

• To handle database queries

• To generate a response

• To pass control to the next middleware

• To terminate the request

What does the Authmiddleware primarily interact with?

• User interface

• Auth repository

• File system

• Database

What is the role of the authorization matrix?

• To store user passwords

• To encrypt data

• To manage server load

• To define roles and permissions

What happens if a token is missing in a request?

• A forbidden response is sent

• The server crashes

• The request is processed normally

• The request is logged for later

What is the first step in the verify API's verification process?

• Sending a response

• Checking user credentials

• Logging the request

• Converting query parameters to a map

Which library is used for token parsing in the verify API?

• JWT

• OAuth

• OpenSSL

• Bcrypt

What is verified in the third check of the verify API?

• Server uptime

• Token expiry

• Database connection

• Resource access for the same user
