Création d'une API REST avec le Routing d'Attributs dans Web API 2 (2024)

FAQs

What is the use of attribute routing in Web API? ›

Attribute routing gives you more control over the URIs in your web API. For example, you can easily create URIs that describe hierarchies of resources. The earlier style of routing, called convention-based routing, is still fully supported. In fact, you can combine both techniques in the same project.

A route can have multiple endpoints associated with it, and which is used depends on the HTTP verb. For example, with the URL `http://example.com/wp-json/wp/v2/posts/123`: The “route” is wp/v2/posts/123 – The route doesn't include wp-json because wp-json is the base path for the API itself.

Web API 2 supports a new type of routing, called attribute routing. As the name implies, attribute routing uses attributes to define routes. Attribute routing gives you more control over the URIs in your web API.

It routes an incoming HTTP request to a particular action method on a Web API controller. Web API supports two types of routing: Convention-based Routing. Attribute Routing.

Conventional routing: The route is determined based on conventions that are defined in route templates that, at runtime, will map requests to controllers and actions (methods). Attribute-based routing: The route is determined based on attributes that you set on your controllers and methods.

Enabling attribute routing in your ASP.NET MVC5 application is simple, just add a call to routes. MapMvcAttributeRoutes() method within RegisterRoutes() method of RouteConfig. cs file. You can also combine attribute routing with convention-based routing.

API is usually a definition term, Endpoint or route are physical representation. When somebody says "build an API" that means you have to define its specification e.g. protocol, request/response schema, (may be) security credentials and (of course) an endpoint to hit.

API Routes let you create an API endpoint inside a Next.js app. You can do so by creating a function inside the pages/api directory that has the following format: // req = HTTP incoming message, res = HTTP server response export default function handler(req, res) { // ... }

Understanding the differences between REST APIs and RESTified endpoints is crucial. REST APIs represent traditional methods of resource access, while RESTified endpoints offer a more dynamic and efficient approach, particularly in environments that necessitate rapid development and flexibility.

In the Internet, there are three types of routing protocols commonly used. They are: distance vector, link state, and path vector. In this chapter, we present the basic concepts and fundamentals behind each of these three types of protocols in a generic framework.

How do I enable attribute routing in Web API? ›

In Web API 2, the Attribute Routing is enabled by default. The config. MapHttpAttributeRoutes(); code which is present in WebApiConfig. cs file enables the Web API Attribute Routing.

Convention-Based Routing and Attribute Routing are the two types of Routing.

Routing API requests

When a client sends an API request, API Gateway first determines which stage to route the request to. If the request explicitly matches a stage, API Gateway sends the request to that stage. If no stage fully matches the request, API Gateway sends the request to the $default stage.

Types of Routing

Routing can be classified into three categories: Static Routing. Default Routing. Dynamic Routing.

The [ApiController] attribute applies inference rules for the default data sources of action parameters. These rules save you from having to identify binding sources manually by applying attributes to the action parameters.

As the name implies, attribute routing means attributes are used to define routes. The Attribute routing provides more control over the URIs in your Web API application by defining routes directly on the actions and controllers. For example, you can easily create URIs that describes the hierarchies of resources.

Attribute Routing provides us with more control over the URIs of our MVC web application. Previous routing mode (convention-based routing) is fully supported by this version of MVC. We may also use the two types of routing within the same project.
