Hapi auth bearer token

hapi Bearer and Access Token authentication scheme

This project is actively maintained and has 100% unit test coverage. If you have any problems using it or have any feature requests, please raise an issue. Please star if using, so I know where to focus time spent on open source work.

Bearer authentication requires validating a token passed in by either the bearer authorization header, or by an access_token query parameter. The 'bearer-access-token' scheme takes the following options:

• validateFunc - (required) a token lookup and validation function with the signature function(token, callback) where:
  • token - the auth token received from the client.
  • callback - a callback function with the signature function(err, isValid, credentials) where:
    • err - an internal 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').
• options - (optional)
  • accessTokenName (Default: 'access_token') - Rename the token query parameter key e.g. 'sample_token_name' would rename the token query parameter to /route1?sample_token_name=12345678.
  • allowQueryToken (Default: true) - Disable accepting token by query parameter, forcing token to be passed in through authorization header.
  • allowMultipleHeaders (Default: false) - Allow multiple authorization headers in request, e.g. Authorization: FD AF6C74D1-BBB2-4171-8EE3-7BE9356EB018; Bearer 12345678

For convenience, the request object can be accessed from this within validateFunc. This allows some greater flexibility with authentication, such different authentication checks for different routes.

var Hapi = require('hapi');

var server = Hapi.createServer('localhost', 8080, {
    cors: true
});

server.pack.register(require('hapi-auth-bearer-token'), function (err) {

    server.auth.strategy('simple', 'bearer-access-token', {
        allowQueryToken: true,              // optional, true by default
        allowMultipleHeaders: false,        // optional, true by default
        accessTokenName: 'access_token',    // optional, 'access_token' by default
        validateFunc: function( token, callback ) {
        
            // For convenience, the request object can be accessed 
            // from `this` within validateFunc.
            var request = this;  
        
            // Use a real strategy here, 
            // comparing with a token from your database for example
            if(token === "1234"){
                callback(null, true, { token: token })
            } else {
                callback(null, false, { token: token })
            }
        }
    });

    server.route({ 
        method: 'GET', 
        path: '/', 
        handler: function (request, reply) {
            reply('success');
        }, 
        config: { auth: 'simple' } 
    });

    server.start(function () {
        console.log('Server started at: ' + server.info.uri);
    })
});
