Access Token

web interface: https://d1gix48j5w3eur.cloudfront.net/buying

1. Navbar > Sign in using mock account (suggested), if you signup with new user will get default role in basicUser, that mean you NOT allow to access all functions.

   • select tab >> Application

   

   • Session Storage > http... > access_token and copy these token to postman

   

3. Go to postman and paste token to Authorization > TYPE: Bearer Token >>

[Token] ...

1. 

2. For auth: UserLevel, need to send “targerUserId” in Params>Path Variables>

   KEY: targetUserId

   VALUE: <targetUserId>

Email

Email use in web interface for get access token.

1. basicUserA

   Email: success+basicUserTest@simulator.amazonses.com

Authorizer

AppLevel

There is no “owner” for this level, users with application level permissions to administer roles can do so

1. Can change other user roles.
2. Can create new roles
3. Change site-wide settings
4. SuperUser permissions for lower level RBAC (eg: User level or Category level RBAC permissions)TODO: so, you all need to give the role permission to user)

allow the role permission to user appLevel

• SuperUser

can do all actions:

CREATE | UPDATE | DELETE | GET | LIST

• VerifiedUser

can do some actions:

CREATE | GET | LIST

• BasicUser

can do few actions:

GET

example reloPermission

{ 
  "roleIdKey":"AppLevel_this-is-uuid-role-superUserA", 
  "service_resource_action":"VariantStandard_Product_AddProduct", 
  "permission": "accept" 
}

setting for authorizer appLevel

• function.yml

For LambdaFunctionHdrApi applevel

LambdaFunctionHdrApi: 
  events: 
   - http: 
       path: Lambda/LambdaAction
       method: post 
       cors: true 
       authorizer: 
         arn: ${self:custom.iz_authorizerAppLevel}
         type request 
         resultTtlInSeconds: 0

UserLevel

• All permissions are linked to one user id.
• Has an owner (the current user), that user always has full permissions for their user id.
• Available roles are shared by all users, any user can create new roles and add permissions, roles can then be used by any users.
• Only the creator of the role can make changes later (for the start - in future we can add RBAC management of user level roles).

example permissions:

• Can administer users roles/permissions
• Can administer sell offers for this user

allow the role permission to user

Allow the role permission to user appLevel

example rolePermission

• Create role permission, user can do action, can create in seed data or run from https://us-east-2.console.aws.amazon.com/apigateway/home?region=us-east-2#/apis/rwnhg855jd/resources/y8erkk : RolePermissionCreateHdrApi

{ 
  "roleIdKey":"UserLevel_this-is-uuid-for-role-verifiedUserA_this-is-uuid-for-role-verifiedUserB", 
  "service_resource_action":"VariantStandard_Product_AddProduct", 
  "permission": "accept" 
}

• Create userRoles, user have role, can create from https://us-east-2.console.aws.amazon.com/apigateway/home?region=us-east-2#/apis/rwnhg855jd/resources/y8erkk : UserRolesCreateHdrApi

{ 
  "userId": "this-is-uuid-for-user-verifiedUserB", 
  "roleIdKey": "UserLevel_this-is-uuid-for-user-verifiedUserA_this-is-uuid-for-user-verifiedUserB" 
}

setting for authorizer userLevel

• function.yml

For LambdaFunctionHdrApi userlevel, need to add adds targetid to api route/path

LambdaFunctionHdrApi: 
  events: 
   - http: 
       path: Lambda/LambdaAction${self:custom.api_path_targetid_suffix}  
       method: post 
       cors: true 
       authorizer: 
         arn: ${self:custom.iz_authorizerUserLevel} 
         type request 
         resultTtlInSeconds: 0
