idempotent rest

In Layman's RestI wonder if you realize that the "right" way to implement heterogeneous application-to-application communication is around, and a debate is raging: while the current mainstream approach is clearly focused on the soap, WSDL, and WS-* specifications of the Web services domain, But there are a few small but resonant voices arguing that the better way is rest, the representational state transfer (Transfer) abbreviation. In this article, I'

of each connection), while rest transmission contains all the status information of the application, therefore, it can greatly reduce the consumption of repeated HTTP connection request resources.Web services with status transmission A Web Service (also called restful web API) that uses HTTP and follows the rest principle. It defines resources in the following three aspects: Intuitive and brief resource

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

experience a very strange browser behavior ("Why did I go back to the home page? Where did everything in my shopping cart go ?"). In Ajax applications using stateful clients and stateless services, server crashes/restarts are completely transparent to users, because server crashes do not affect the session status, these are all stored in the user's browser. The stateless service behavior is idempotent and can be determined separately by the content r

errors caused by the client, such as request parameter error or access to a nonexistent resource, these must be idempotent operations, and cannot change the state of the server [Carefree child Note: In fact, the state of the server changes means that the operation is not idempotent].The return code of the 5XX mainly indicates errors caused by the server, and usually these errors are thrown by the underlyin

that it can easily handle server faults. As we have discussed earlier, server-side Web applications with integrated user experience usually save a large number of user session statuses on the server. If the server fails, the session state will be lost, and the user will experience a very strange browser behavior ("Why did I go back to the home page? Where did everything in my shopping cart go ?"). In Ajax applications using stateful clients and stateless services, server crashes/restarts are co

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├──

multiple times, and its effect is the same as when sending the first request.If the resource is successfully modified, the PUT request response status code is (OK) and returns 404 (not FOUND) if the resource does not exist.DELETEDelete is usually used to delete a resource. The delete request is also idempotent, because after you delete a resource, even if you repeatedly send the same delete request multiple times, the result is the same: the resource

REST refers to a set of schema constraints and principles The most important REST principle of a WEB application is that the interaction between the client and the server is stateless between requests, and each request of the client must contain the information necessary to understand the request, and the server restarts at any point in time between requests and the client will not be notified Stat

Representational State transfer (representational-transfer,rest) has been widely accepted in the Web, and is based on the SOAP and Web Service Description Language (Web services Description language,w SDL) is a simpler alternative to WEB services. The key evidence of this shift in interface design is the adoption of REST by mainstream WEB 2.0 service providers, including Yahoo, Google and Facebook, which ha

IntroducedRepresentational state Transfer (REST) is an architectural principle that treats a Web service as a resource that can be uniquely identified by its URL. A key feature of RESTful Web Services is the explicit use of HTTP methods to represent calls to different operations.The basic design principles of REST Use the HTTP protocol approach for typical CRUD operations: POST-Create Resource

BasisREST defines a set of architectural principles that you can use to design a system-resource-centric WEB service, including how clients written in different languages process and transfer resource state over HTTP. If you consider the number of Web services it uses, REST has become the most important Web service design model in recent years. In fact, REST has a very large impact on the Web, and because o

Server-side services may be requested by a large number of browsers, may also be called by third-party applications, so the overall need to consider the external "application Inter
