Struct actix_web::middleware::CookieSessionBackend

pub struct CookieSessionBackend(_);

Use cookies for session storage.

CookieSessionBackend creates sessions which are limited to storing fewer than 4000 bytes of data (as the payload must fit into a single cookie). An Internal Server Error is generated if the session contains more than 4000 bytes.

A cookie may have a security policy of signed or private. Each has a respective CookieSessionBackend constructor.

A signed cookie is stored on the client as plaintext alongside a signature such that the cookie may be viewed but not modified by the client.

A private cookie is stored on the client as encrypted text such that it may neither be viewed nor modified by the client.

The constructors take a key as an argument. This is the private key for cookie session - when this value is changed, all session data is lost. The constructors will panic if the key is less than 32 bytes in length.

Example

use actix_web::middleware::CookieSessionBackend;

let backend: CookieSessionBackend = CookieSessionBackend::signed(&[0; 32])
    .domain("www.rust-lang.org")
    .name("actix_session")
    .path("/")
    .secure(true);

Methods

impl CookieSessionBackend

pub fn signed(key: &[u8]) -> CookieSessionBackend

Construct new signed CookieSessionBackend instance.

Panics if key length is less than 32 bytes.

pub fn private(key: &[u8]) -> CookieSessionBackend

Construct new private CookieSessionBackend instance.

Panics if key length is less than 32 bytes.

pub fn path<S: Into<String>>(self, value: S) -> CookieSessionBackend

Sets the path field in the session cookie being built.

pub fn name<S: Into<String>>(self, value: S) -> CookieSessionBackend

Sets the name field in the session cookie being built.

pub fn domain<S: Into<String>>(self, value: S) -> CookieSessionBackend

Sets the domain field in the session cookie being built.

pub fn secure(self, value: bool) -> CookieSessionBackend

Sets the secure field in the session cookie being built.

If the secure field is set, a cookie will only be transmitted when the connection is secure - i.e. https

pub fn max_age(self, value: Duration) -> CookieSessionBackend

Sets the max-age field in the session cookie being built.
