Calling the API

Now that the project has been set up, we can use the vasystem-api crate to call the API. In this example, we will use the same example values as in the Authentication guide.

Please note that we recommend not hard-coding the values in your code, but instead using environment variables or a configuration file. We have hard-coded them in the example below for simplicity.

src/main.rs

use vasystem_api::{
    api::{ListAirlinesRequest, ListRoutesRequest},
    Client, Request,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::connect(
        "staralliancevirtual.org",
        "client-id",
        "client-secret",
        vec!["airlines".to_string(), "routes".to_string()],
    )
    .await?;
    
    let response = client
        .airlines()
        .list_airlines(Request::new(ListAirlinesRequest {}))
        .await?;

    println!("RESPONSE = {:?}", response);
    
    Ok(())
}

Replace the values in the Client::connect call with the values you received from the Authentication guide.

You can now run the code with cargo run and you should see the following output:

RESPONSE = Response { metadata: MetadataMap { headers: {"content-type": "application/grpc", "grpc-status": "0", "grpc-message": ""} }, message: ListAirlinesResponse { airlines: [Airline { id: "...", icao_code: "...", iata_code: "..", display_icao_code: "...", display_iata_code: "..", name: "..." }, ...] }, extensions: Extensions }
