"Every developer working with the Web needs to read this book." -- David Heinemeier Hansson, creator of the Rails framework "RESTful Web Services finally provides a practical roadmap for constructing services that embrace the Web, instead of trying to route around it." -- Adam Trachtenberg, PHP author and EBay Web Services Evangelist You've built web sites that can be used by humans. But can you also build web sites that are usable by machines? That's where the future lies, and that's what RESTful Web Services shows you how to do. The World Wide Web is the most popular distributed application in history, and Web services and mashups have turned it into a powerful distributed computing platform. But today's web service technologies have lost sight of the simplicity that made the Web successful. They don't work like the Web, and they're missing out on its advantages. This book puts the "Web" back into web services. It shows how you can connect to the programmable web with the technologies you already use every day. The key is REST, the architectural style that drives the Web. This book: * Emphasizes the power of basic Web technologies — the HTTP application protocol, the URI naming standard, and the XML markup language * Introduces the Resource-Oriented Architecture (ROA), a common-sense set of rules for designing RESTful web services * Shows how a RESTful design is simpler, more versatile, and more scalable than a design based on Remote Procedure Calls (RPC) * Includes real-world examples of RESTful web services, like Amazon's Simple Storage Service and the Atom Publishing Protocol * Discusses web service clients for popular programming languages * Shows how to implement RESTful services in three popular frameworks — Ruby on Rails, Restlet (for Java), and Django (for Python) * Focuses on practical issues: how to design and implement RESTful web services and clients This is the first book that applies the REST design philosophy to real web services. It sets down the best practices you need to make your design a success, and the techniques you need to turn your design into working code. You can harness the power of the Web for programmable applications: you just have to work with the Web instead of against it. This book shows you how.

The web is no longer just the web, of course, and in some ways it has strayed far from its original incarnation as a relatively simple platform for distributed computing. Enthusiasts of representational state transfer (REST), an architectural style or a way of judging architectures, find significant gaps between that abstract concept and the reality. Master practitioners Richardson and Ruby have learned from their research into multitudes of ad hoc REST-like architectures and here offer a starting point for applications of those concepts to web services through resource-oriented architecture (ROA). They use basic web technologies, introduce ROA as a common-sense set of rules, show how RESTful designs are simpler, more versatile and more scalable than present remote procedure call practices, include current front-line examples, explain how REST works with programming languages, and show how to implement RESTful services in popular frameworks.

This easy-to-understand reference shows how to use the Representational StateTransfer Web architecture, or REST, to provide services over the Web that arefundamentally simple, both for producers and the consumers.
