func NewHandler ¶
func NewHandler(auther Auther, next http.Handler, secret []byte, duration time.Duration, loginFormHandler, loginErrorHandler, registerFormHandler, registerErrorHandler http.Handler, hash crypto.Hash) (*Handler, error)
NewHandler initializes a Handler for use.
dsn is the data source name (https://github.com/mattn/go-sqlite3#connection-string) of the sqlite database where logins are stored.
next is the Handler whose ServeHTTP method is called for valid sessions.
secret is used to verify cookie authenticity.
duration specifies how long a session should be valid.
loginFormHandler, loginErrorHandler, registerFormHandler and registerErrorHandler are handlers used to display login and registration pages. loginFormHandler should post a form with "username" and "password" fields to "/login", registrationFormHandler should post a form with "username", "password" and "passwordAgain" fields to "/register". for testing purposes or if styling doesn't matter, the Default* Handlers defined in this package can be used.
hash is a cryptographic hash to use for cookie authenticity.
