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.

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');
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?;

GetRolesForUser()

GetRolesForUser gets the roles that a user has.

For example:

res := e.GetRolesForUser("alice")
const res = await e.getRolesForUser('alice')
$res = $e->getRolesForUser("alice");
var res = e.GetRolesForUser("alice");
let roles = e.get_roles_for_user("alice", None); // No domain

GetUsersForRole()

GetUsersForRole gets the users that has a role.

For example:

res := e.GetUsersForRole("data1_admin")
const res = await e.getUsersForRole('data1_admin')
$res = $e->getUsersForRole("data1_admin");
var res = e.GetUsersForRole("data1_admin");
let users = e.get_users_for_role("data1_admin", None); // No domain

HasRoleForUser()

HasRoleForUser determines whether a user has a role.

For example:

res := e.HasRoleForUser("alice", "data1_admin")
const res = await e.hasRoleForUser('alice', 'data1_admin')
$res = $e->hasRoleForUser("alice", "data1_admin");
var res = e.HasRoleForUser("alice", "data1_admin");
let has = e.has_role_for_user("alice", "data1_admin", None); // No domain

AddRoleForUser()

AddRoleForUser adds a role for a user. Returns false if the user already has the role (aka not affected).

e.AddRoleForUser("alice", "data2_admin")
await e.addRoleForUser('alice', 'data2_admin')
$e->addRoleForUser("alice", "data2_admin");
var added = e.AddRoleForUser("alice", "data2_admin");

or
var deleted = await e.DeleteRoleAsync("data2_admin");
let deleted = e.delete_role("data2_admin").await?;

e.DeletePermission("read")
await e.deletePermission('read')
$e->deletePermission("read");
var deleted = e.DeletePermission("read");
or
var deleted = await e.DeletePermissionAsync("read");
let deleted = e.delete_permission(vec!["read".to_owned()]).await?;

AddPermissionForUser()

AddPermissionForUser adds a permission for a user or role. Returns false if the user or role already has the permission (aka not affected).

For example:

e.AddPermissionForUser("bob", "read")
await e.addPermissionForUser('bob', 'read')
$e->addPermissionForUser("bob", "read");
var added = e.AddPermissionForUser("bob", "read");
or
var added = await e.AddPermissionForUserAsync("bob", "read");
let added = e.add_permission_for_user("bob", vec!["read".to_owned()]).await?;

AddPermissionsForUser()

AddPermissionsForUser adds multiple permissions for a user or role. Returns false if the user or role already has one of the permissions (aka not affected).

For example:

let permissions = vec![
    vec!["data1".to_owned(), "read".to_owned()],
    vec!["data2".to_owned(), "write".to_owned()],
];

let all_added = e.add_permissions_for_user("bob", permissions).await?;

DeletePermissionForUser()

DeletePermissionForUser deletes a permission for a user or role. Returns false if the user or role does not have the permission (aka not affected).

For example:

e.DeletePermissionForUser("bob", "read")
await e.deletePermissionForUser("bob", "read")
$e->deletePermissionForUser("bob", "read");
var deleted = e.DeletePermissionForUser("bob", "read");
or
var deleted = await e.DeletePermissionForUserAsync("bob", "read");
let deleted = e.delete_permission_for_user("bob", vec!["read".to_owned()]).await?;

DeletePermissionsForUser()

DeletePermissionsForUser deletes permissions for a user or role. Returns false if the user or role does not have any permissions (aka not affected).

For example:

e.DeletePermissionsForUser("bob")
await e.deletePermissionsForUser('bob')
$e->deletePermissionsForUser("bob");

or
var deletedAtLeastOne = await e.DeletePermissionsForUserAsync("bob");
let deleted_at_least_one = e.delete_permissions_for_user("bob").await?;

GetPermissionsForUser()

GetPermissionsForUser gets permissions for a user or role.

For example:

e.GetPermissionsForUser("bob")
await e.getPermissionsForUser('bob')
$e->getPermissionsForUser("bob");
var permissions = e.GetPermissionsForUser("bob");

HasPermissionForUser()

HasPermissionForUser determines whether a user has a permission.

For example:

e.HasPermissionForUser("alice", []string{"read"})
await e.hasPermissionForUser('alice', 'read')
$e->hasPermissionForUser("alice", []string{"read"});
var has = e.HasPermissionForUser("bob", "read");
let has = e.has_permission_for_user("alice", vec!["data1".to_owned(), "read".to_owned()]);

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:

e.GetImplicitRolesForUser("alice")
await e.getImplicitRolesForUser("alice")
$e->getImplicitRolesForUser("alice");
var implicitRoles = e.GetImplicitRolesForUser("alice");
e.get_implicit_roles_for_user("alice", None); // No domain

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:

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:

e.GetImplicitPermissionsForUser("alice")
await e.getImplicitPermissionsForUser("alice")
$e->getImplicitPermissionsForUser("alice");
var implicitPermissions = e.GetImplicitPermissionsForUser("alice");
e.get_implicit_permissions_for_user("alice", None); // No domain

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:

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]]

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