Final answer:
The REST uniform interface principle consists of methods such as GET for retrieving resources, POST for creating new resources, PUT for updating existing ones, DELETE for removing resources, and PATCH for partial updates. These methods facilitate a consistent and standardized interaction between clients and servers in RESTful services.
Step-by-step explanation:
Methods of the REST Uniform Interface Principle
The uniform interface principle is one of the central tenets of the Representational State Transfer (REST) architectural style. This principle dictates that a uniform interface between clients and servers should be maintained, enabling the decoupling of the architecture and simplification of interactions. The methods commonly associated with the REST uniform interface are:
- GET - Used to retrieve information from the server. This method is read-only and has no side effects, making it safe for repeated calls.
- POST - Used to create a new resource on the server. This method can change the state of the server and thus it's not idempotent.
- PUT - Used to update an existing resource or create a new resource if it does not exist. The call is idempotent, meaning multiple identical requests will have the same effect as a single request.
- DELETE - Used to remove a resource from the server. This method is idempotent as well.
- PATCH - Used to apply partial modifications to a resource. It is not necessarily idempotent.
By adhering to these methods, RESTful services ensure that operations are performed in a consistent way, allowing different clients and services to interact with one another through a standard set of actions.
