Answer from AI
The main HTTP methods are used for different purposes when interacting between client and server:
-
GET — requests data from the server. A safe and idempotent method, it should not change the server's state. Used for retrieving resources.
-
POST — sends data to the server to create a new resource or perform an operation. Not idempotent; repeated calls may create duplicates.
-
PUT — updates or creates a resource at the specified URI. Idempotent: repeated calls with the same data result in the same outcome.
-
DELETE — deletes the resource at the specified URI. Idempotent: repeated deletion of the same resource will not change the state after the first deletion.
Example:
- GET /users/123 — get information about user 123
- POST /users — create a new user
- PUT /users/123 — update data for user 123
- DELETE /users/123 — delete user 123
Each method has its semantic meaning and should be used according to the HTTP standard.
