class litestar.middleware.session.client_side.ClientSideSessionBackend

基类：BaseSessionBackend[CookieBackendConfig]

Cookie backend for SessionMiddleware.

__init__(config: CookieBackendConfig) → None

Initialize ClientSideSessionBackend.

参数:

config -- SessionCookieConfig instance.

dump_data(data: Any, scope: Scope | None = None) → list[bytes]

Given serializable data, including pydantic models and numpy types, dump it into a bytes string, encrypt, encode and split it into chunks of the desirable size.

参数:

• data -- Data to serialize, encrypt, encode and chunk.

• scope -- The ASGI connection scope.

备注

• The returned list is composed of a chunks of a single base64 encoded string that is encrypted using AES-CGM.

返回:

List of encoded bytes string of a maximum length equal to the CHUNK_SIZE constant.

load_data(data: list[bytes]) → dict[str, Any]

Given a list of strings, decodes them into the session object.

参数:

data -- A list of strings derived from the request's session cookie(s).

返回:

A deserialized session value.

get_cookie_keys(connection: ASGIConnection) → list[str]

Return a list of cookie-keys from the connection if they match the session-cookie pattern.

参数:

connection -- An ASGIConnection instance

返回:

A list of session-cookie keys

get_cookie_key_set(connection: ASGIConnection) → set[str]

Return a set of cookie-keys from the connection if they match the session-cookie pattern.

Added in version 2.8.3.

参数:

connection -- An ASGIConnection instance

返回:

A set of session-cookie keys

async store_in_message(scope_session: ScopeSession, message: Message, connection: ASGIConnection) → None

Store data from scope_session in Message in the form of cookies. If the contents of scope_session are too large to fit a single cookie, it will be split across several cookies, following the naming scheme of <cookie key>-<n>. If the session is empty or shrinks, cookies will be cleared by setting their value to "null"

参数:

• scope_session -- Current session to store

• message -- Outgoing send-message

• connection -- Originating ASGIConnection containing the scope

返回:

None

async load_from_connection(connection: ASGIConnection) → dict[str, Any]

Load session data from a connection's session-cookies and return it as a dictionary.

参数:

connection -- Originating ASGIConnection

返回:

The session data

get_session_id(connection: ASGIConnection) → str | None

Try to fetch session id from connection ScopeState. If one does not exist, generate one.

参数:

connection -- Originating ASGIConnection containing the scope

返回:

Session id str or None if the concept of a session id does not apply.

class litestar.middleware.session.client_side.CookieBackendConfig

基类：BaseBackendConfig[ClientSideSessionBackend]

Configuration for [SessionMiddleware] middleware.

secret: bytes

A secret key to use for generating an encryption key.

Must have a length of 16 (128 bits), 24 (192 bits) or 32 (256 bits) characters.

key: str = 'session'

Key to use for the cookie inside the header, e.g. session=<data> where session is the cookie key and <data> is the session data.

备注

• If a session cookie exceeds 4KB in size it is split. In this case the key will be of the format session-{segment number}.

max_age: int = 1209600

Maximal age of the cookie before its invalidated.

path: str = '/'

Path fragment that must exist in the request url for the cookie to be valid.

Defaults to '/'.

domain: str | None = None

Domain for which the cookie is valid.

__init__(secret: bytes, key: str = 'session', max_age: int = 1209600, scopes: set[~typing.Literal[ScopeType.HTTP, ScopeType.WEBSOCKET]] = <factory>, path: str = '/', domain: str | None = None, secure: bool = False, httponly: bool = True, samesite: ~typing.Literal['lax', 'strict', 'none'] = 'lax', exclude: str | list[str] | None = None, exclude_opt_key: str = 'skip_session') → None

secure: bool = False

Https is required for the cookie.

httponly: bool = True

Forbids javascript to access the cookie via 'Document.cookie'.

samesite: Literal['lax', 'strict', 'none'] = 'lax'

Controls whether or not a cookie is sent with cross-site requests.

Defaults to lax.

exclude: str | list[str] | None = None

A pattern or list of patterns to skip in the session middleware.

exclude_opt_key: str = 'skip_session'

An identifier to use on routes to disable the session middleware for a particular route.
