http_listener_hello.rs

//! An example to showcase how to build directly a HTTP server that listens on `127.0.0.1:62007`
//! and returns a JSON response with the method and path of the request.
//!
//! # Run the example
//!
//! ```sh
//! cargo run --example http_listener_hello --features=http-full
//! ```
//!
//! # Expected output
//!
//! The server will start and listen on `:62007`. You can use `curl` to interact with the service:
//!
//! ```sh
//! curl -v http://127.0.0.1:62007
//! ```
//!
//! You should see a response with `HTTP/1.1 200 OK` and a JSON body with the method and path of the request.
