Aperçu

Introduction​

All users associated with a single Casdoor organization share access to the organization's applications. Cependant, il peut y avoir des cas où vous souhaitez restreindre l'accès des utilisateurs à certaines applications ou à des ressources spécifiques au sein d'une application. Dans de tels cas, vous pouvez utiliser la fonctionnalité Permission fournie par Casbin.

Understanding Casbin Concepts​

Before delving deeper into the topic, it is important to have a basic understanding of how Casbin works and its related concepts:

  • Model: Defines the structure of your permission policies and the criteria for matching requests against these policies and their outcomes. You can configure models in the Models page in Casdoor.
  • Policy: Describes the specific permission rules (who can access what resources with what actions). You configure policies in the Permissions page in Casdoor.
  • Adapter: An abstraction layer that shields Casbin's executor from the source of the Policy, allowing the storage of Policies in various locations like files or databases. Learn more about Adapters.

Configuring Permissions in Casdoor​

Where to Configure​

In the Casdoor Web UI, you'll work with two main pages:

  1. Models Page: Navigate to Models in the sidebar to add or edit Models for your organization.

    Model Edit Page

  2. Permissions Page: Navigate to Permissions in the sidebar to configure permission policies.

    Permission Edit Page

How Permissions Work​

Returning to the subject of permission configuration in Casdoor:

  1. Add a Model: First, create a Model for your organization in the Models page within the Casdoor Web UI.
  2. Configure a Policy: Then, add a Policy (permission rules) for your organization in the Permissions page.

L'Éditeur en ligne Casbin peut vous fournir des fichiers Modèle et Politique adaptés à vos scénarios d'utilisation spécifiques. Vous pouvez importer sans effort le fichier Modèle dans Casdoor via son interface utilisateur Web pour une utilisation par le Casbin intégré. For the Policy configuration (i.e., the Permissions page in the Casdoor Web UI), refer to the Permission Configuration guide for detailed instructions.

Using Permissions with Your Application​

Tout comme votre application doit appliquer le contrôle des permissions via le Casbin intégré de Casdoor, Casdoor lui-même utilise son propre Modèle et Politique pour réguler les permissions d'accès pour les interfaces API via Casbin. Bien que Casdoor puisse appeler Casbin à partir du code interne, les applications externes ne le peuvent pas.

En tant que solution, Casdoor expose une API pour que les applications externes appellent le Casbin intégré. See the Exposed Casbin APIs documentation for definitions of these API interfaces and instructions on how to use them.

Account Item Permissions​

Casdoor also provides fine-grained permission control at the user account field level through the Edit Organization page:

  • View rule: Control who can view specific user account fields
  • Modify rule: Control who can modify specific user account fields

These rules can be set to:

  • Public: Everyone has permission
  • Self: Each user has their own permission
  • Admin: Only administrators have permission

Learn more in the Account Customization documentation.

Role-Based Access Control​

Casdoor supports role-based permissions where you can assign roles to users and configure permission policies for these roles. This allows you to manage permissions at the role level rather than individual user level.
