[−][src]Crate roa_router
The router module of roa.
This module provides many endpoint wrappers like Router
, Dispatcher
and a context extension RouterParam
.
Example
use roa_router::{Router, RouterParam, get, allow}; use roa_core::{App, Context, Error, MiddlewareExt, Next}; use roa_core::http::{StatusCode, Method}; use roa_tcp::Listener; use async_std::task::spawn; async fn gate(_ctx: &mut Context<()>, next: Next<'_>) -> Result<(), Error> { next.await } async fn query(ctx: &mut Context<()>) -> Result<(), Error> { Ok(()) } async fn create(ctx: &mut Context<()>) -> Result<(), Error> { Ok(()) } async fn graphql(ctx: &mut Context<()>) -> Result<(), Error> { Ok(()) } #[tokio::main] async fn main() -> Result<(), Box<dyn std::error::Error>> { let router = Router::new() .gate(gate) .on("/restful", get(query).post(create)) .on("/graphql", allow([Method::GET, Method::POST], graphql)); let app = App::new(()) .end(router.routes("/api")?); let (addr, server) = app.run()?; spawn(server); let resp = reqwest::get(&format!("http://{}/api/restful", addr)).await?; assert_eq!(StatusCode::OK, resp.status()); let resp = reqwest::get(&format!("http://{}/restful", addr)).await?; assert_eq!(StatusCode::NOT_FOUND, resp.status()); Ok(()) }
