RBAC API

A more friendly API for RBAC. This API is a subset of Management API. The RBAC users could use this API to simplify the code.

Reference

global variable e is Enforcer instance.

Go
Node.js
PHP
Python
.NET
Rust
Java
e, err := NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")
const e = await newEnforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv')
$e = new Enforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv');
e = casbin.Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")
var e = new Enforcer("path/to/model.conf", "path/to/policy.csv");
let mut e = Enforcer::new("examples/rbac_model.conf", "examples/rbac_policy.csv").await?;
Enforcer e = new Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv");

GetRolesForUser()

GetRolesForUser gets the roles that a user has.

For example:

Go
Node.js
PHP
Python
.NET
Rust
Java
res := e.GetRolesForUser("alice")
const res = await e.getRolesForUser('alice')
$res = $e->getRolesForUser("alice");
roles = e.get_roles_for_user("alice")
var res = e.GetRolesForUser("alice");
let roles = e.get_roles_for_user("alice", None); // No domain
List<String> res = e.getRolesForUser("alice");

GetUsersForRole()

GetUsersForRole gets the users that has a role.

For example:

Go
Node.js
PHP
Python
.NET
Rust
Java
res := e.GetUsersForRole("data1_admin")
const res = await e.getUsersForRole('data1_admin')
$res = $e->getUsersForRole("data1_admin");
users = e.get_users_for_role("data1_admin")
var res = e.GetUsersForRole("data1_admin");
let users = e.get_users_for_role("data1_admin", None); // No domain
List<String> res = e.getUsersForRole("data1_admin");

HasRoleForUser()

HasRoleForUser determines whether a user has a role.

For example:

Go
Node.js
PHP
Python
.NET
Rust
Java

let has = e.has_permission_for_user("alice", vec!["data1".to_owned(), "read".to_owned()]);
boolean has = e.hasPermissionForUser("alice", "read");

GetImplicitRolesForUser()

GetImplicitRolesForUser gets implicit roles that a user has. Compared to GetRolesForUser(), this function retrieves indirect roles besides direct roles.

For example:
g, alice, role:admin
g, role:admin, role:user

GetRolesForUser("alice") can only get: ["role:admin"].
But GetImplicitRolesForUser("alice") will get: ["role:admin", "role:user"].

For example:

Go
Node.js
PHP
Python
.NET
Rust
Java
e.GetImplicitRolesForUser("alice")
await e.getImplicitRolesForUser("alice")
$e->getImplicitRolesForUser("alice");
e.get_implicit_roles_for_user("alice")
var implicitRoles = e.GetImplicitRolesForUser("alice");
e.get_implicit_roles_for_user("alice", None); // No domain
List<String> implicitRoles = e.getImplicitRolesForUser("alice");

GetImplicitUsersForRole()

GetImplicitUsersForRole gets all users inheriting the role. Compared to GetUsersForRole(), this function retrieves indirect users.

For example:
g, alice, role:admin
g, role:admin, role:user

GetUsersForRole("role:user") can only get: ["role:admin"].
But GetImplicitUesrsForRole("role:user") will get: ["role:admin", "alice"].

For example:

Go
Node.js
Java
users := e.GetImplicitUsersForRole("role:user")
const users = e.getImplicitUsersForRole("role:user");
List<String> users = e.getImplicitUsersForRole("role:user");

GetImplicitPermissionsForUser()

GetImplicitPermissionsForUser gets implicit permissions for a user or role.
Compared to GetPermissionsForUser(), this function retrieves permissions for inherited roles.

For example:
p, admin, data1, read
p, alice, data2, read
g, alice, admin

GetPermissionsForUser("alice") can only get: [["alice", "data2", "read"]].
But GetImplicitPermissionsForUser("alice") will get: [["admin", "data1", "read"], ["alice", "data2", "read"]].

For example:

Go
Node.js
PHP
Python
.NET
Rust
Java
e.GetImplicitPermissionsForUser("alice")
await e.getImplicitPermissionsForUser("alice")
$e->getImplicitPermissionsForUser("alice");
e.get_implicit_permissions_for_user("alice")
var implicitPermissions = e.GetImplicitPermissionsForUser("alice");
e.get_implicit_permissions_for_user("alice", None); // No domain
List<List<String>> implicitPermissions = e.getImplicitPermissionsForUser("alice");

GetNamedImplicitPermissionsForUser()

GetNamedImplicitPermissionsForUser gets implicit permissions for a user or role by named policy Compared to GetImplicitPermissionsForUser(), this function allow you to specify the policy name.

For example: p, admin, data1, read p2, admin, create g, alice, admin

GetImplicitPermissionsForUser("alice") only get: [["admin", "data1", "read"]], whose policy is default "p"

But you can specify the policy as "p2" to get: [["admin", "create"]] by GetNamedImplicitPermissionsForUser("p2","alice")

For example:

Go
Python
e.GetNamedImplicitPermissionsForUser("p2","alice")
e.get_named_implicit_permissions_for_user("p2", "alice")

GetDomainsForUser()

GetDomainsForUser gets all domains which a user has.

For example: p, admin, domain1, data1, read p, admin, domain2, data2, read p, admin, domain2, data2, write g, alice, admin, domain1 g, alice, admin, domain2

GetDomainsForUser("alice") could get ["domain1", "domain2"]

For example:

Go
result, err := e.GetDomainsForUser("alice")

GetImplicitResourcesForUser()

GetImplicitResourcesForUser returns all policies that should be true for user.

For example:

p, alice, data1, read
p, bob, data2, write
p, data2_admin, data2, read
p, data2_admin, data2, write

g, alice, data2_admin

GetImplicitResourcesForUser("alice") will return [[alice data1 read] [alice data2 read] [alice data2 write]]

Go
resources, err := e.GetImplicitResourcesForUser("alice")
