app.route('/api/user')
        .get(v.query('email').notEmpty().isEmail().m(), userManagementController.listUsers)
        .post(v.body('name').notEmpty().m(), 
              v.body('email').isEmail().m(),
              v.body('password').minLength(7).maxLength(20).m(), 
              userManagementController.create);

app.route('/api/user/:email').get(v.params('email').notEmpty().isEmail().m(), userManagementController.readUser)

for validating req.query.{paramname} use v.query method
