Flight Path Tracking API

Goal

Create a microservice API that can help understand and track how a particular person's flight path may be queried.

Required Structure

[['SFO', 'EWR']] => ['SFO', 'EWR']
[['ATL', 'EWR'], ['SFO', 'ATL']] => ['SFO', 'EWR']
[['IND', 'EWR'], ['SFO', 'ATL'], ['GSO', 'IND'], ['ATL', 'GSO']] => ['SFO', 'EWR']

API endpoint

With Postman

/index
- method: GET
- url: https://127.0.0.1:8080/ (or https://localhost:8080)
/flight
- method: POST
- url: https://127.0.0.1:8080/flight (or https://localhost:8080/flight)
- header : Content-Type = application/json
- body(raw): [["SFO", "EWR"]]

Framework

Actix - Web framework for Rust

Input Validation Check

Validate JSON data

// should fail
[[["from", "to"]]]
[["A", "B"], ["C", "D"], {"key": "value"}]

Only one in, one out for every airport

if flight_from.contains_key(destination) || flight_to.contains_key(source) {
    return Err(error::ErrorBadRequest("Invalid input"));
}

Only one start, one end for the overall flight path

let mut current = flight_start.to_string();
let mut count = 1;
loop {
    if current.eq(flight_end) {
        break;
    }
    match flight_to.get(&current) {
        None => {
            return Err(error::ErrorBadRequest("Invalid input"));
        }
        Some(&airport) => {
            current = airport.into();
        }
    }
    count = count + 1;
}
if count != airports.len() {
    return Err(error::ErrorBadRequest("Invalid input"));
}
