and Authorization

File: pkg/acl/acl.go

This file implements authentication and authorization logic for Autoflow. It provides functionality for verifying user identities, checking permissions, and managing roles.

Authentication:

• Autoflow currently uses a local authentication mechanism.
• Users are stored in a local database and authenticate using username and password.
• Authentication information is managed by the AuthService interface.
• The implementation of AuthService is responsible for verifying user credentials and returning a token for authorized users.

Authorization:

• Autoflow uses role-based access control (RBAC).
• Roles are defined in the Role struct, which includes a set of permissions.
• Permissions are represented as strings and are used to control access to different resources and actions within Autoflow.
• The Role struct is defined in pkg/acl/model.go.
• The Authorizer interface provides methods for checking user permissions and enforcing authorization rules.
• The Authorizer interface is implemented in pkg/acl/authorizer.go.
• The Authorizer implementation uses the Role information and checks permissions against the user’s assigned roles.

Examples:

// Check if a user has permission to perform an action
          func (a *Authorizer) HasPermission(user string, permission string) bool {
              // ...
          }
          
          // Get the roles assigned to a user
          func (a *Authorizer) GetRoles(user string) ([]string, error) {
              // ...
          }
          
          // Check if a user is allowed to access a resource
          func (a *Authorizer) IsAllowed(user string, resource string) bool {
              // ...
          }
          

Notes:

• The acl package provides basic authentication and authorization functionality.
• Users can be created, updated, and deleted using the AuthService interface.
• Roles can be managed using the RoleService interface.
• The authorization logic is currently implemented using a simple permission-based approach.
• The authorization rules can be customized by modifying the Role definitions and the Authorizer implementation.
• The acl package can be extended to support more complex authorization scenarios, such as access control lists (ACLs) and attribute-based access control (ABAC).
