authenticate()

Authenticates the current connection with a JWT token.

Method Syntax
db.authenticate(token)

Arguments

Example usage

Note: the following example uses the ureq crate with the json feature to first send a request to the database’s /signup endpoint which returns a token. The reqwest crate and others can be used here instead.

Alternatively, you could use a command like the following, copy the returned token, and paste it into the .authenticate() method.

curl -X POST -H "Accept: application/json" -d '{"ns":"test","db":"test","ac":"account","user":"info@surrealdb.com","pass":"123456"}' http://localhost:8000/signup

As the DEFINE ACCESS statement below shows, a token will remain valid by default for 15 minutes.

// Use the following statement to set up the access
//
// DEFINE ACCESS account ON DATABASE TYPE RECORD
// 	SIGNUP ( CREATE user SET email = $email, pass = crypto::argon2::generate($pass) )
// 	SIGNIN ( SELECT * FROM user WHERE email = $email AND crypto::argon2::compare(pass, $pass) )
// 	DURATION FOR TOKEN 15m, FOR SESSION 12h
// ;

// DEFINE TABLE cat SCHEMALESS
//     PERMISSIONS for select, update, delete, create
//     WHERE $auth.id;
