session options
| options | default | |
|---|---|---|
| session_cache_size | 65536 | max number of session in cache |
| session_cache_timeout(ms) | 900000 | clear session objects which is not operated for a period of time from buffer, default 15 minutes |

-
session cache is used to keep session consistency among http requires.
-
the timeout of session cache must be larger than its delay
-
The client-side has only the session ID. The session is operated on the server-side.
setup the backend database.
returns a cookie-based session filter.
returns a header-based session filter.
returns an api handler that gets a new session ID.
options
| options | default | |
|---|---|---|
| session_jwt_algo | null | see jws.ALGORITHMS in fib-jws |
| session_jwt_key | null | sign key. see in fib-jws |
- see fib-jws https://github.com/fibjs/fib-jws
- set session_jwt_algo and session_jwt_key to enable JWT
// session_jwt_algo is encryption algorithms in fib-jws
// session_jwt_key is to verify the signature.
var session = new Session(conn, { session_jwt_algo: 'HS256', session_jwt_key: verify_key })- set the JSON Web Token in cookie
- sign_key for signature, may be different from session_jwt_key, depending on the algorithm.
- according to JSON Web Token specification, one user session can only be called setTokenCookie once for set user session info. The second will throw an exception: new Error('Can't modify the JSON Web Token')
- default value r.session={}
// sign user info: { id: 12345, name: "Frank" }, and set the cookie
// r is request
session.setTokenCookie(r, { id: 12345, name: "Frank" }, sign_key)- get token for api filter mode, see session.api_filter
session.getToken ({ id: 12345, name: "Frank" }, sign_key)
