REST (Representational State Transfer) is an architectural style commonly used for designing networked applications, particularly APIs that need to handle multiple content types over HTTP. Here's a detailed explanation:
* Content Negotiation:
* Definition: REST APIs support content negotiation, allowing clients to request either XML or JSON formats by setting theAcceptheader in HTTP requests.
* Flexibility: This capability makes REST ideal for scenarios where an API needs to serve multiple content types.
* HTTP Protocol:
* Usage: REST APIs operate over HTTP/1.1, making them compatible with web standards and easily accessible by various clients (browsers, mobile apps, etc.).
* Methods: Supports standard HTTP methods like GET, POST, PUT, DELETE, allowing for CRUD operations.
* Advantages:
* Stateless: Each request from a client to server must contain all the information needed to understand and process the request.
* Scalability: RESTful services can handle a high load of requests efficiently.
