Comments

To view all comments that were created by the previous handler, we have to send a GET request to the comments microservice with the get_request function that we created before and resend the response data to a client:

fn comments(_req: HttpRequest<State>) -> FutureResponse<HttpResponse> {
    let fut = get_request("http://127.0.0.1:8003/list")
        .map(|data| {
            HttpResponse::Ok().body(data)
        });
    Box::new(fut)
}
