Today we'll be writing a working web API using an extremely simple HTTP library controlable from the console of your computer. Let gonna se the implementation
First, crate a new folder and add k_board & snowboard.
cargo new http-api && cd http-api && cargo add k_board && cargo add snowboard
use k_board::{Keyboard, Keys};
use snowboard::{response, Server};
fn main() {
for key in Keyboard::new() {
match key {
Keys::Enter => router("localhost:3000"),
Keys::Letter('q') => break,
_ => {}
}
}
}
fn router(localhost: &str) {
println!("Running in localhost:3000 - `curl localhost:3000`");
Server::new(localhost).run(|req| {
println!("Request: {:?}", req);
response!(ok, "You are in localhost 3000!\n")
});
}
If you press enter you active the server listening all call, then when you make a curl localhost:300 you will receive the answer of the server.
mateo@debian:~/http-api$ curl localhost:3000
You are in localhost 3000!
That a simple example in which it just take the enter key as an activator of the server, if your looking for an specific handling of the keys for server activation , you can look at Keys struct of k_board.
