Struct actix_web::dev::AppRouter

pub struct AppRouter<C, P, B, T> { /* fields omitted */ }

Application router builder - Structure that follows the builder pattern for building application instances.

Methods

impl<C, P, B, T> AppRouter<C, P, B, T> where
    P: 'static,
    B: MessageBody,
    T: NewService<Request = ServiceRequest<P>, Response = ServiceResponse<B>, Error = Error, InitError = ()>, 

pub fn route(self, path: &str, route: Route<P>) -> Self

Configure route for a specific path.

This is a simplified version of the App::service() method. This method can not be could multiple times, in that case multiple resources with one route would be registered for same resource path.

use actix_web::{web, App, HttpResponse};

fn index(data: web::Path<(String, String)>) -> &'static str {
    "Welcome!"
}

fn main() {
    let app = App::new()
        .route("/test1", web::get().to(index))
        .route("/test2", web::post().to(|| HttpResponse::MethodNotAllowed()));
}

pub fn service<F>(self, factory: F) -> Self where
    F: HttpServiceFactory<P> + 'static, 

Register http service.

Http service is any type that implements HttpServiceFactory trait.

Actix web provides several services implementations:

• Resource is an entry in resource table which corresponds to requested URL.
• Scope is a set of resources with common root path.
• "StaticFiles" is a service for static files support

pub fn wrap<M, B1, F>(
    self,
    mw: F
) -> AppRouter<C, P, B1, impl NewService<Request = ServiceRequest<P>, Response = ServiceResponse<B1>, Error = Error, InitError = ()>> where
    M: Transform<T::Service, Request = ServiceRequest<P>, Response = ServiceResponse<B1>, Error = Error, InitError = ()>,
    B1: MessageBody,
    F: IntoTransform<M, T::Service>, 

Register a middleware.

pub fn wrap_fn<B1, F, R>(
    self,
    mw: F
) -> AppRouter<C, P, B1, impl NewService<Request = ServiceRequest<P>, Response = ServiceResponse<B1>, Error = Error, InitError = ()>> where
    B1: MessageBody,
    F: FnMut(ServiceRequest<P>, &mut T::Service) -> R + Clone,
    R: IntoFuture<Item = ServiceResponse<B1>, Error = Error>, 

Register a middleware function.

pub fn default_resource<F, U>(self, f: F) -> Self where
    F: FnOnce(Resource<P>) -> Resource<P, U>,
    U: NewService<Request = ServiceRequest<P>, Response = ServiceResponse, Error = Error, InitError = ()> + 'static, 

Default resource to be used if no matching resource could be found.

pub fn external_resource<N, U>(self, name: N, url: U) -> Self where
    N: AsRef<str>,
    U: AsRef<str>, 

Register an external resource.

External resources are useful for URL generation purposes only and are never considered for matching at request time. Calls to HttpRequest::url_for() will work as expected.

use actix_web::{web, App, HttpRequest, HttpResponse, Result};

fn index(req: HttpRequest) -> Result<HttpResponse> {
    let url = req.url_for("youtube", &["asdlkjqme"])?;
    assert_eq!(url.as_str(), "https://youtube.com/watch/asdlkjqme");
    Ok(HttpResponse::Ok().into())
}

fn main() {
    let app = App::new()
        .service(web::resource("/index.html").route(
            web::get().to(index)))
        .external_resource("youtube", "https://youtube.com/watch/{video_id}");
}
