Struct RequestInfo

pub struct RequestInfo { /* private fields */ }

Expand description

Represents some information for the incoming request.

It’s used to access request information e.g. headers, method, uri etc for the Post Middleware and for the error handling;

Implementations§

impl RequestInfo

pub fn headers(&self) -> &HeaderMap

Returns the request headers.

pub fn method(&self) -> &Method

Returns the request method type.

pub fn uri(&self) -> &Uri

Returns the request uri.

pub fn version(&self) -> Version

Returns the request’s HTTP version.

pub fn data<T: Send + Sync + 'static>(&self) -> Option<&T>

Access data which was shared by the RouterBuilder method data.

Please refer to the Data and State Sharing for more info.

pub fn context<T: Send + Sync + Clone + 'static>(&self) -> Option<T>

Access data from the request context.

§Examples

use routerify::{Router, RouteParams, Middleware, RequestInfo};
use routerify::ext::RequestExt;
use hyper::{Response, Request, Body};

let router = Router::builder()
    .middleware(Middleware::pre(|req: Request<Body>| async move {
        req.set_context("example".to_string());

        Ok(req)
    }))
    .middleware(Middleware::post_with_info(|res, req_info: RequestInfo| async move {
        let text = req_info.context::<String>().unwrap();
        println!("text is {}", text);

        Ok(res)
    }))
    .get("/hello", |req| async move {
        let text = req.context::<String>().unwrap();

        Ok(Response::new(Body::from(format!("Hello from : {}", text))))
     })
     .build()
     .unwrap();
