Rest
RESTful web services are lightweight, highly scalable, maintainable and are often used to create APIs for web-based applications.
The REST server provides connectivity to resources, which helps the client to access and update resources. The resources are recognized by the URIs. The REST API creates a variety of outputs to represent a resource, such as JSON. REST architecture-oriented web services are called RESTful web services.
The REST architecture makes use of four commonly used HTTP methods.
| GET | This method helps in offering read-only access for the resources. |
|---|---|
| POST | This method is implemented for creating a new resource or to update a previously created resource. |
| DELETE | This method is implemented for removing a resource. |
| PUT | This method is implemented for updating an existing resource or creating a fresh one. |
REST Web services follow four basic design principles:
- Uses HTTP methods explicitly.
- Stateless.
- Exposes directory structure-like URIs.
- Transfer JSON (JavaScript Object Notation), XML or both.
