Working with REST APIs

The subject of this chapter is the development and use of simple RESTful servers and clients using the Go programming language. REST is an acronym for REpresentational State Transfer and is primarily an architecture for designing web services. Although web services exchange information in HTML, RESTful services usually use JSON format, which is well supported by Go. REST is not tied to any operating system or system architecture and is not a protocol; however, to implement a RESTful service, you need to use a protocol such as HTTP. When developing RESTful servers, you need to create the appropriate Go structures and perform the necessary marshaling and unmarshaling operations for the exchange of JSON data.

This truly important and practical chapter covers:

  • An introduction to REST
  • Developing RESTful servers and clients
  • Creating a functional RESTful server
  • Creating a RESTful client
  • Uploading and downloading binary files...
