Struct actix_web::web::Redirect

source ·

pub struct Redirect { /* private fields */ }

Expand description

An HTTP service for redirecting one path to another path or URL.

By default, the “307 Temporary Redirect” status is used when responding. See this MDN article on why 307 is preferred over 302.

Examples

As service:

use actix_web::{web, App};

App::new()
    // redirect "/duck" to DuckDuckGo
    .service(web::redirect("/duck", "https://duck.com"))
    .service(
        // redirect "/api/old" to "/api/new"
        web::scope("/api").service(web::redirect("/old", "/new"))
    );

As responder:

use actix_web::{web::Redirect, Responder};

async fn handler() -> impl Responder {
    // sends a permanent (308) redirect to duck.com
    Redirect::to("https://duck.com").permanent()
}

Implementations§

source §

impl Redirect

source

pub fn new(
from: impl Into<Cow<'static, str>>,
to: impl Into<Cow<'static, str>>
) -> Self

Construct a new Redirect service that matches a path.

This service will match exact paths equal to from within the current scope. I.e., when registered on the root App, it will match exact, whole paths. But when registered on a Scope, it will match paths under that scope, ignoring the defined scope prefix, just like a normal Resource or Route.

The to argument can be path or URL; whatever is provided shall be used verbatim when setting the redirect location. This means that relative paths can be used to navigate relatively to matched paths.

Prefer Redirect::to() when using Redirect as a responder since from has no meaning in that context.

Examples

App::new()
    // redirects "/oh/hi/mark" to "/oh/bye/johnny"
    .service(Redirect::new("/oh/hi/mark", "../../bye/johnny"));

source

pub fn to(to: impl Into<Cow<'static, str>>) -> Self

Construct a new Redirect to use as a responder.

Only receives the to argument since responders do not need to do route matching.

Examples

use actix_web::{web::Redirect, Responder};

async fn admin_page() -> impl Responder {
    // sends a temporary 307 redirect to the login path
    Redirect::to("/login")
}

source

pub fn permanent(self) -> Self

Use the “308 Permanent Redirect” status when responding.

See this MDN article on why 308 is preferred over 301.

source

pub fn temporary(self) -> Self

Use the “307 Temporary Redirect” status when responding.

See this MDN article on why 307 is preferred over 302.

source

pub fn see_other(self) -> Self

Use the “303 See Other” status when responding.

This status code is semantically correct as the response to a successful login, for example.

source

pub fn using_status_code(self, status: StatusCode) -> Self

Allows the use of custom status codes for less common redirect types.

In most cases, the default status (“308 Permanent Redirect”) or using the temporary method, which uses the “307 Temporary Redirect” status have more consistent behavior than 301 and 302 codes, respectively.

// redirects would use "301 Moved Permanently" status code
Redirect::new("/old", "/new")
    .using_status_code(StatusCode::MOVED_PERMANENTLY);

// redirects would use "302 Found" status code
Redirect::new("/old", "/new")
    .using_status_code(StatusCode::FOUND);
