Basic authentication plugin

hapi-auth-basic

Lead Maintainer: Matt Harrison

Basic authentication requires validating a username and password combination. The 'basic' scheme takes the following options:

• validateFunc - (required) a user lookup and password validation function with the signature function(request, username, password, callback) where:
  • request - is the hapi request object of the request which is being authenticated.
  • username - the username received from the client.
  • password - the password received from the client.
  • callback - a callback function with the signature function(err, isValid, credentials) where:
    • err - an internal error. If defined will replace default Boom.unauthorized error
    • isValid - true if both the username was found and the password matched, otherwise false.
    • credentials - a credentials object passed back to the application in request.auth.credentials. Typically, credentials are only included when isValid is true, but there are cases when the application needs to know who tried to authenticate even when it fails (e.g. with authentication mode 'try').
• allowEmptyUsername - (optional) if true, allows making requests with an empty username. Defaults to false.
• unauthorizedAttributes - (optional) if set, passed directly to Boom.unauthorized if no custom err is defined. Useful for setting realm attribute in WWW-Authenticate header. Defaults to undefined.

    }
};

const validate = function (request, username, password, callback) {

    const user = users[username];
    if (!user) {
        return callback(null, false);
    }
