The C++ REST SDK-based REST server
In this section, we have leveraged code from Marius Bancila's excellent article about the C++ REST SDK. In fact, the key/value database code is borrowed from his implementation. The authors are thankful to him for the excellent article, available at https://mariusbancila.ro/blog/2017/11/19/revisited-full-fledged-client-server-example-with-c-rest-sdk-2-10/.
Let's write a microservice that puts everything we have learned so far in the context of the Microsoft C++ REST SDK. We will consume the REST services by leveraging the RxCurl library written by Kirk Shoop as part of his Twitter analysis application. We have added support to the DELETE and PUT verbs.
