Expand description

Opinionated request identity service for Actix Web apps.

`IdentityService` middleware can be used with different policies types to store identity information.

A cookie based policy is provided. `CookieIdentityPolicy` uses cookies as identity storage.

To access current request identity, use the `Identity` extractor.

    use actix_web::*;
    use actix_identity::{Identity, CookieIdentityPolicy, IdentityService};

    #[get("/")]
    async fn index(id: Identity) -> String {
        // access request identity
        if let Some(id) = id.identity() {
            format!("Welcome! {}", id)
        } else {
            "Welcome Anonymous!".to_owned()
        }
    }

    #[post("/login")]
    async fn login(id: Identity) -> HttpResponse {
        // remember identity
        id.remember("User1".to_owned());
        HttpResponse::Ok().finish()
    }

    #[post("/logout")]
    async fn logout(id: Identity) -> HttpResponse {
        // remove identity
        id.forget();
        HttpResponse::Ok().finish()
    }

    HttpServer::new(move || {
        // create cookie identity backend (inside closure, since policy is not Clone)
        let policy = CookieIdentityPolicy::new(&[0; 32])
            .name("auth-cookie")
            .secure(false);

        App::new()
            // wrap policy into middleware identity middleware
            .wrap(IdentityService::new(policy))
            .service(services![index, login, logout])
    })
