    pub struct RedisActorSessionStore { /* private fields */ }

Expand description

Use Redis as session storage backend.

    use actix_web::{web, App, HttpServer, HttpResponse, Error};
    use actix_session::{SessionMiddleware, storage::RedisActorSessionStore};
    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 = "127.0.0.1:6379";
        HttpServer::new(move ||
                App::new()
                .wrap(
                    SessionMiddleware::new(
                        RedisActorSessionStore::new(redis_connection_string),
                        secret_key.clone()
                    )
                )
                .default_service(web::to(|| HttpResponse::Ok())))
            .bind(("127.0.0.1", 8080))?

## §Implementation notes

`RedisActorSessionStore` leverages `actix-redis`’s `RedisActor` implementation - each thread worker gets its own connection to Redis.

### §Limitations

`RedisActorSessionStore` does not currently support establishing authenticated connections to Redis. Use `RedisSessionStore` if you need TLS support.

## Implementations§

source§

### impl RedisActorSessionStore

source

#### pub fn builder<S: Into<String>>( connection_string: S ) -> RedisActorSessionStoreBuilder

A fluent API to configure `RedisActorSessionStore`.

It takes as input the only required input to create a new instance of `RedisActorSessionStore`—a connection string for Redis.

source

#### pub fn new<S: Into<String>>(connection_string: S) -> RedisActorSessionStore

Create a new instance of `RedisActorSessionStore` using the default configuration. It takes as input the only required input to create a new instance of `RedisActorSessionStore` - a connection string for Redis.
