poem-lambda documentation may need updating

Bit strapped for time so I explained the issue in the loom video.

poem/main.rs at master · poem-web/poem - 16 May 2022 - Watch Video

Basically the examples for lambda-hello-world shows that we set up routing without the AWS ApiGateway stage name. However, in practice, the stage name needs to be included in the routing for the requests to resolve correctly.

By the way, I think this is a pretty awesome library. :) Great work.

I think the fix for api gateway stage name is pretty simple, we can nest everything inside of a route matching the stage name. example below.

#[tokio::main]
async fn main() -> Result<(), Error> {
    if std::env::var_os("RUST_LOG").is_none() {
        std::env::set_var("RUST_LOG", "poem=debug");
    }
    tracing_subscriber::fmt::init();

    let app = Route::new()
        .at("/", get(simple))
        .at("/pet", get(pet))
        .at("/hello/:name", get(hello));

    let stage_name = String::from("/prod");
    let server = Route::new().nest(stage_name, app);
    run(server).await
}
