RESTinio provides built‑in type conversion for query string parameters (RESTinio - Casting Parameters).

You can use castto like this:

#include 
if (qp.has("AcceptTime")) {
    long dAcceptTime = restinio::castto(qp["AcceptTime"]);
}

This can be even more simplified with the use of valueor:

#include 
long dAcceptTime = restinio::valueor(qp, "AcceptTime", 0);

value_or returns a default value if AcceptTime key is missing. If the conversion fails, it will throw an exception.
