Setting Up Postman for API Testing When Using Passport Authorization

Question

I am a bit confused while trying to get Postman to work when testing the API of my application. Namely, I am using Passport authentication; however, I do not know which type it defaults to or uses in my code. How can I figure this out and which type should I choose in Postman?

Here is the relevant Passport code:

var login = require('./login');
var signup = require('./signup');
var User = require('../models/user');

module.exports = function(passport, path, nodemailer, sesTransport, EmailTemplate, templateDir, template){

    // Passport needs to be able to serialize and deserialize users to support persistent login sessions
    passport.serializeUser(function(user, done) {
        //console.log('serializing user: ');console.log(user);
        done(null, user._id);
    });

    passport.deserializeUser(function(id, done) {
        User.findById(id, function(err, user) {
            //console.log('deserializing user:',user);
            done(err, user);
        });
    });

    // Setting up Passport Strategies for Login and SignUp/Registration
    login(passport);
    signup(passport, path, nodemailer, sesTransport, EmailTemplate, templateDir, template);

}

Lastly, pretty much all of my API points only work when the user is logged in. How can I emulate the same behavior in Postman by saving the authorization credentials?

Edit:

Perhaps this code is relevant as well:


module.exports = function(passport){

    passport.use('login', new LocalStrategy({
            passReqToCallback : true,
            usernameField: 'email',
            passwordField: 'password'
        },
        function(req, username, password, done) { 
            // check in mongo if a user with username exists or not
            User.findOne({ 'email' :  username }, 
                function(err, user) {
                    // In case of any error, return using the done method
                    if (err)
                        return done(err);
                    // Username does not exist, log the error and redirect back
                    if (!user){
                        console.log('User Not Found with username '+username);
                        return done(null, false, req.flash('message', 'User Not found.'));                 
                    }
                    // User exists but wrong password, log the error 
                    if (!isValidPassword(user, password)){
                        console.log('Invalid Password');
                        return done(null, false, req.flash('message', 'Invalid Password')); // redirect back to login page
                    }
                    // User and password both match, return user from done method
                    // which will be treated like success
                    return done(null, user);
                }
            );

        })
    );


    var isValidPassword = function(user, password){
        return bCrypt.compareSync(password, user.password);
    }  
}

Answer 1

I don't have a code that runs local auth strategy but I think the following postman setup should work for you.

To request for an access token; assuming your endpoint is auth/local.

1. open up Postman
2. create a POST request
3. under authorization tab set "No Auth"
4. under body tab -> click on x-www-form-urlencoded
5. add a key named email and enter the user email
6. add a key named password and enter the associated secret for the email

See token request screenshot below:

The response will come back with an access_token.

To use the access_token simply create a HTTP request and in the HEADER tab, add the key Authorization followed by a value of "Bearer

See use token request screenshot:

Answer 2

I use this and it works fine in postman. After getting response of access token under the Authorization tab. select "Bearer Token" from "Type" drop-down. and Token with field will appear on right. enter the access token.

This works fine with Laravel REST APIs.
