Using http methods without decorators

[PauloVitorRocha]

Describe the issue
An HTTP method is safe when used to perform a read-only operation, such as retrieving information. Knowing that it is not so easy to change http to https, I suggest the use of decorators that obligate strict GET methods to only accept GET requests.

Expected behavior
Strict GET methods should have @require_http_methods(["GET"]) decorator.
