Cevap

The HTTP PUT verb is used to perform a full update or replacement of an existing resource.
In REST-based APIs, the HTTP PUT method maps directly to the Update operation in the CRUD model when performing a complete replacement of an existing resource.

Adım Adım Çözüm

1
Identify the target CRUD operation requested
The requirement specifies modifying/replacing an existing configuration object on the server.
Mapping the operational goal to CRUD determines the appropriate HTTP verb.
2

In RESTful architecture, HTTP PUT performs a full update/replacement of an existing resource.
PUT replaces the resource representation completely at the specified URI.
