For example, a Sub-resource locator could return a different resource if a user is a preferred customer:@Path ("basket") public shoppingbasketresource get (@Context SecurityContext

Today, someone asked me a question: "Why would someone choose SOAP (Simple Object access, Protocol, and rather than REST (representational state Transfer, representational status pass) It? "My answer is:" I often hear the general empirical law is 'use REST unless you have a clear reason to use SOAP .’”。 He asked again, "for example?" "I thought for a minute, and then honestly answered that I had not yet met

I have an inference that, in the computer world, all the important concepts that the developer remembers, there is a cool name acronym, or the developer will soon leave it behind. Ajax, SOAP, and rest, for example, attest to this. Rest can be widely used in the computer field, and its path is unusual. This term was created by Roy Fielding. Fielding graduated from the University of California, Irvine, for th

In REST, we can write the method for accepting POST requests as follows: @ POST@ Consumes (MediaType. APPLICATION_JSON) Public Response createProduct (CreateProductJson createProductJson, @ Context UriInfo uriInfo ){ CreateProductJson is the JSON expression used by our server to receive a request such as CreateProudct. Then we can use createProductJson. similar methods such as getProduct () Get the product object, and then process the object ar

REST service Introduction, rest Service RESTful service is an architecture model that has become popular in recent years. Its lightweight web service uses the native http get, PUT, POST, and DELETE methods. Compared with the complex SOAP and XML-RPC, the REST mode Web Service is obviously more concise, and more web services begin to adopt the

When HTTP is invented, rest is already there. Unfortunately, over the years, the Web development model has increasingly deviated from the nature of HTTP, trifles the pursuit of RPC and other things. At this point rest back into the eyes of people, no doubt let everyone begin to reflect on the past detours.This article does not want to introduce rest from scratch,

Different people seem to have different definitions of rest, some are very strict, and others are more liberal. I tend to think that the rest architecture exists in a continuous range, As shown in the figure: The basic idea behind rest is that we can think of the following: · The simpler the better. · The web has been a very successful one. · The web is ve

The previous section describes how noir can easily create a web app. However, in my actual project, only rest API development is required, and the page is handed over to HTML and JavaScript, noir is not required to render the webpage in the background. Similarly, you do not need to restart the program. Create a rest directory under the src directory, which contains a test. CLJ file: $ tree.├── models├──

Recently developing a rest-based API interface in the product, combined with your recent research on node. JS, would like to develop a rest client for testing purposes based on it.With the initial research, node. JS is very handy to develop HTTP client.Reasons to choose node:1. It's very convenient to test JSON-formatted data using a fully JavaScript-based node2. Node has a good community support. (GitHub i
