Struct RedisSessionStore 

pub struct RedisSessionStore { /* private fields */ }

Available on crate feature redis-session only.

Use Redis as session storage backend.

use actix_web::{web, App, HttpServer, HttpResponse, Error};
use actix_session::{SessionMiddleware, storage::RedisSessionStore};
use actix_web::cookie::Key;

// The secret key would usually be read from a configuration file/environment variables.
fn get_secret_key() -> Key {
    // [...]
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let secret_key = get_secret_key();
    let redis_connection_string = "redis://127.0.0.1:6379";
    let store = RedisSessionStore::new(redis_connection_string).await.unwrap();

    HttpServer::new(move ||
            App::new()
            .wrap(SessionMiddleware::new(
                store.clone(),
                secret_key.clone()
            ))
            .default_service(web::to(|| HttpResponse::Ok())))
        .bind(("127.0.0.1", 8080))?
        .run()
        .await
}

TLS support

Add the redis-rs-tls-session or redis-rs-tls-session-rustls feature flag to enable TLS support. You can then establish a TLS connection to Redis using the rediss:// URL scheme:

use actix_session::{storage::RedisSessionStore};

let redis_connection_string = "rediss://127.0.0.1:6379";
let store = RedisSessionStore::new(redis_connection_string).await.unwrap();

Pooled Redis Connections

When the redis-pool crate feature is enabled, a pre-existing pool from deadpool_redis can be provided.

use actix_session::storage::RedisSessionStore;
use deadpool_redis::{Config, Runtime};

let redis_cfg = Config::from_url("redis://127.0.0.1:6379");
let redis_pool = redis_cfg.create_pool(Some(Runtime::Tokio1)).unwrap();

let store = RedisSessionStore::new_pooled(redis_pool);

Implementation notes

RedisSessionStore leverages the redis crate as the underlying Redis client.
