SOAP, REST, and More. Service Station More On REST Jon Flanders In the last two columns, I've described the basics of REST and talked about exposing and consuming Web feeds.

SOAP, REST, and More

In this column, I'll answer a number of questions that often come up when I make presentations or conduct training sessions on using REST to build service-based applications. Which is better, REST or SOAP? This is one of the most common questions I get about REST, and it is probably the least fair. Comparing REST with the remote procedure call (RPC) style of building client-server applications would be more accurate. In contrast to RPC, REST lacks the metadata-generated proxy (see the next question for more information), which means that the client is less coupled to the service. My perspective is that both REST and SOAP can be used to implement similar functionality, but in general SOAP should be used when a particular feature of SOAP is needed, and the advantages of REST make it generally the best option otherwise.

Representational State Transfer

REST (representational state transfer) est un style d’architecture pour les systèmes hypermédia distribués, créé par Roy Fielding en 2000 dans le chapitre 5 de sa thèse de doctorat[1]. REST n’est pas un protocole (tel que HTTP) ou un format. Ce style d'architecture est particulièrement bien adapté au World Wide Web mais n'en est pas dépendant. Les contraintes, telles que définies par Roy Fielding, peuvent s'appliquer à d'autres protocoles d'application que HTTP. HATEOAS.

The HATEOAS constraint decouples client and server in a way that allows the server functionality to evolve independently.

HATEOAS

Details[edit] A REST client enters a REST application through a simple fixed URL. All future actions the client may take are discovered within resource representations returned from the server. The media types used for these representations, and the link relations they may contain, are standardized. The client transitions through application states by selecting from the links within a representation or by manipulating the representation in other ways afforded by its media type.

For example [2] here is a GET request to fetch an Account resource, requesting details in an XML representation: Service web. Un article de Wikipédia, l'encyclopédie libre.

Les nouvelles architectures front Web et leur impact sur la DSI – partie 2. Dans la partie 1 de cet article, nous avons traité des nouvelles architectures front-end basées sur des applications Web massivement Javascript appelant des API offertes par un serveur back-end : les nouvelles architectures front Web et leur impact sur les DSI – Partie 1.

Les nouvelles architectures front Web et leur impact sur la DSI – partie 2

Nous avons vu qu’elles sont apparues ces dernières années grâce à l’augmentation des performances des navigateurs et à l’amélioration des outils d’industrialisation des développements Javascript. Dans cette seconde partie, nous nous intéresserons aux raisons pour lesquelles on devrait choisir ces nouvelles architectures, aux opportunités qu’elles offrent, et aux conséquences sur les organisations des directions informatiques. Pourquoi utiliser ces nouvelles archis? Pour mutualiser le code back-end pour de multiples clients. Les nouvelles architectures front Web et leur impact sur les DSI – Partie 1. RESTful Web Services: A Tutorial. More than a decade after its introduction, REST has become one of the most important technologies for Web applications.

RESTful Web Services: A Tutorial

Its importance is likely to continue growing quickly as all technologies move towards an API orientation. Every major development language now includes frameworks for building RESTful Web services. As such, it is important for Web developers and architects to have a clear understanding of REST and RESTful services. This tutorial explains REST architecturally, then dives into the details of using it for common API-based tasks. While REST stands for Representational State Transfer, which is an architectural style for networked hypermedia applications, it is primarily used to build Web services that are lightweight, maintainable, and scalable. RESTful Web services: The basics. The basics REST defines a set of architectural principles by which you can design Web services that focus on a system's resources, including how resource states are addressed and transferred over HTTP by a wide range of clients written in different languages.

RESTful Web services: The basics

If measured by the number of Web services that use it, REST has emerged in the last few years alone as a predominant Web service design model. In fact, REST has had such a large impact on the Web that it has mostly displaced SOAP- and WSDL-based interface design because it's a considerably simpler style to use. REST didn't attract this much attention when it was first introduced in 2000 by Roy Fielding at the University of California, Irvine, in his academic dissertation, "Architectural Styles and the Design of Network-based Software Architectures," which analyzes a set of software architecture principles that use the Web as a platform for distributed computing (see Resources for a link to this dissertation). What Are Web Services and Where Are They used? Web Services are the means by which devices communicate over the World Wide Web.

What Are Web Services and Where Are They used?

Whether you use a mobile application, search engine or an enterprise system, the user piece of the application (the interface) resides on your device. The data, and potentially the business rules, live on some other server on the network. 5 Programming Languages Marked for Death - Dice Insights. Update: So how did we do with these predictions?

5 Programming Languages Marked for Death - Dice Insights

Check out our March 2016 article that breaks down which of the following languages continue to retain market-share… and which are, indeed, imploding. As developers embrace new programming languages, older languages can go one of two ways: stay in use, despite fading popularity, or die out completely. Une comparaison de Spring MVC et de JAX-RS. Introduction Ces dernières années, REST est devenu un concept important, influençant la conception des frameworks, protocoles et applications web.

Getting Started · Building a RESTful Web Service. In Spring’s approach to building RESTful web services, HTTP requests are handled by a controller. These components are easily identified by the @RestController annotation, and the GreetingController below handles GET requests for /greeting by returning a new instance of the Greeting class: src/main/java/hello/GreetingController.java package hello; import java.util.concurrent.atomic.AtomicLong;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController; @RestControllerpublic class GreetingController { private static final String template = "Hello, %s!

"; private final AtomicLong counter = new AtomicLong(); @RequestMapping("/greeting") public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) { return new Greeting(counter.incrementAndGet(), String.format(template, name)); }} The Greeting object must be converted to JSON. The Go Programming Language. Web Development Trends For 2015 And Beyond. Web Development Trends For 2015 And Beyond In this post, I will take a look at web development trends happening now and I would like to share my thoughts, observations and predictions for year 2015 and beyond. I have been working on Web technologies since early 2000, but last few years, I have been mainly involving with Cloud solution architectures. As a Web developer, I have worked on .Net, Node.js and Go technology stacks for developing Web apps and Web services.

Recently, I have just looked on the Web technology and development trends as a whole, and I would like to share my thoughts and observations. First, let me share some of the current trends I have observed on both usability and architecture. Trends in Usability Now days, user experience is getting more importance than ever before, and Responsive Web Design (RWD) is becoming a must have feature for web sites. Trends in Application Architecture The Rise of API Driven Development. Patterns d'authentification pour les API REST. «Tout le monde ressent le besoin d'écrire son propre protocole d'authentification», explique George Reese, selon lui l'une des choses qu'il a apprise en travaillaint sur une API pour les fournisseurs de cloud et les fournisseurs de SaaS.

API Security in REST vs SOAP. RFC 6749 - The OAuth 2.0 Authorization Framework. [Docs] [txt|pdf] [draft-ietf-oauth-v2] [IPR] [Errata] PROPOSED STANDARD Errata Exist Internet Engineering Task Force (IETF) D. Hardt, Ed. Request for Comments: 6749 Microsoft Obsoletes: 5849 October 2012 Category: Standards Track ISSN: 2070-1721 Abstract The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own behalf.

This specification replaces and obsoletes the OAuth 1.0 protocol described in RFC 5849. Status of This Memo This is an Internet Standards Track document. Securing RESTful Web Services with OAuth2. As an active committer on Spring Security OAuth and the Cloud Foundry UAA, one of the questions I get asked the most is: “When and why would I use OAuth2?” The answer, as often with such questions, is “it depends.” However, I must admit, there are some features of OAuth2 that make it compelling in a wide variety of situations, especially in systems composed of many lightweight web services.
