OAuth 2.0 Cookbook

By: Adolfo Eloy Nascimento

Overview of this book

OAuth 2.0 is a standard protocol for authorization and focuses on client development simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and so on. This book also provides useful recipes for solving real-life problems using Spring Security and creating Android applications. The book starts by presenting you how to interact with some public OAuth 2.0 protected APIs such as Facebook, LinkedIn and Google. You will also be able to implement your own OAuth 2.0 provider with Spring Security OAuth2. Next, the book will cover practical scenarios regarding some important OAuth 2.0 profiles such as Dynamic Client Registration, Token Introspection and how to revoke issued access tokens. You will then be introduced to the usage of JWT, OpenID Connect, and how to safely implement native mobile OAuth 2.0 Clients. By the end of this book, you will be able to ensure that both the server and client are protected against common vulnerabilities.

Improving performance using cache for remote validation

This recipe will show how to improve the performance of the Resource Server when it has to remotely validate access tokens. To help on performance, we will use a cache strategy to avoid making requests to/oauth/check_tokenevery time an OAuth's protected resource is requested.

Getting ready

This recipe is an improvement on the previous recipe that we will create a new Resource Server which will cache issued access tokens. So to run this recipe, we need the application remote-authserver created for the Remote validation using token introspection recipe. This recipe will rely on Redis for cache, the MySQL database, and will be developed using Java 8 with Spring Boot.

How to do it...

Follow the next steps to improve the performance of a Resource Server that uses RemoteTokenValidation to check for access token validity with Spring Security OAuth2:

  1. You can just copy the remote-resourceapplication created for the Remote Validation using token introspection...
