Web APis

[Axel Casillas via Digitalmars-d-learn]

Hi there,

I'm trying to implement web api's into a terminal program. With 
some help at the IRC have gotten pretty far but just hit a 
roadblock trying to manipulate the web api to accept input from 
the user.

Example:

auto content = 
get("www.webapiurl.com/data/v4/example?name=category&from=2022-01-24&to=2023-01-24&apikey=01010101010101010101");

writefln! %s (content);

the above is just an example and for the most part it works but I 
am unable to make the 'category','from=date' and 'to=date' a user 
modified variable.

It doesn't matter how I attempt to split the API into different 
sections and define variables before running the program it wont 
compile.

Has anybody ever run into this and if someone has could you point 
me to some example code that might make it ease for me to 
understand, would greatly appreciate.
