Go Cookbook

Overview of this book

Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library. This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers. The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.

Implementing an OAuth2 token storage interface

In the previous recipe, we retrieved a token for our client and performed API requests. The downside of this approach is that we have no long-term storage for our token. In an HTTP server, for example, we'd like to have consistent storage of the token between requests.

This recipe will explore modifying the OAuth2 client to store a token between requests and retrieve them at will using a key. For the sake of simplicity, this key will be a file, but it could also be a database, Redis, and so on.

Getting ready

Refer to the Getting ready section of the Making use of OAuth2 clients recipe.
