Storing and retrieving data

The application will listen to any POST request and will store the content of the request body as a text.

Storing data

Here is this curl example (needs curl installed to test it), or you can simply use Postman

curl --location --request POST 'localhost:8080/set' \
--header 'Content-Type: text/plain' \
--data-raw 'text-or-number-to-store'

In the example above we make a POST request to /set with the content text-or-number-to-store in the request body

Retrieving data

The application will listen to any GET request to return the stored data

curl --location --request GET 'localhost:8080/get'

In the example above we make a GET request to /get to retrieve a plain text value of what was previously stored.

Choosing ports

Either port will be able to retrieve or store the value, you can use them at your very best convenience
