Answer from AI
The POST and PUT methods are used to send data to the server but have different semantic meanings and behaviors:
-
POST is used to create new resources. POST requests are usually not idempotent, meaning that repeating the request can create multiple resources or have other effects. For example, submitting a registration form.
-
PUT is used to create or replace a resource at a specific URL. PUT requests are idempotent: repeating the same request with the same data will not change the result. For example, updating user information by ID.
Example:
- POST /users — creates a new user.
- PUT /users/123 — updates or creates a user with ID 123.
The choice of method depends on the API logic and data handling requirements.
