RBAC API

This RBAC API simplifies common role-based access control operations. It provides a subset of the Management API tailored for RBAC users.

The global variable e represents an 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');

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()`

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()`

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:

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:

e.GetImplicitPermissionsForUser("alice")

await e.getImplicitPermissionsForUser("alice")

$e->getImplicitPermissionsForUser("alice");

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")

예를 들어:

e.GetNamedImplicitPermissionsForUser("p2","alice")

var permissions = 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

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

For example:

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

var result = e.GetDomainsForUser("alice");

`GetImplicitResourcesForUser()`

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")

var resources = e.GetImplicitResourcesForUser("alice");

Note: only users will be returned, roles (2nd arg in "g") will be excluded.

users, err := e.GetImplicitUsersForPermission("data1", "read")

var users = e.GetImplicitUsersForPermission("data1", "read");

`GetImplicitObjectPatternsForUser()`

For example:

p, admin, chronicle/123, location/*, read
p, user, chronicle/456, location/789, read
g, alice, admin
g, bob, user

GetImplicitObjectPatternsForUser("alice", "chronicle/123", "read") will return ["location/*"]. GetImplicitObjectPatternsForUser("bob", "chronicle/456", "read") will return ["location/789"].

patterns, err := e.GetImplicitObjectPatternsForUser("alice", "chronicle/123", "read")

const patterns = await e.getImplicitObjectPatternsForUser("alice", "chronicle/123", "read")

$patterns = $e->getImplicitObjectPatternsForUser("alice", "chronicle/123", "read");

var patterns = e.GetImplicitObjectPatternsForUser("alice", "chronicle/123", "read");

let patterns = e.get_implicit_object_patterns_for_user("alice", "chronicle/123", "read").await?;

List<String> patterns = e.getImplicitObjectPatternsForUser("alice", "chronicle/123", "read");

`GetAllowedObjectConditions()`

Returns object conditions that a user can access.

For example:

p, alice, r.obj.price < 25, read
p, admin, r.obj.category_id = 2, read
p, bob, r.obj.author = bob, write

g, alice, admin

e.GetAllowedObjectConditions("alice", "read", "r.obj.") will return ["price < 25", "category_id = 2"], nil

Note:

prefix: You can customize the prefix of the object conditions, and "r.obj." is commonly used as a prefix. After removing the prefix, the remaining part is the condition of the object. If there is an obj policy that does not meet the prefix requirement, an errors.ERR_OBJ_CONDITION will be returned.
If the 'objectConditions' array is empty, return errors.ERR_EMPTY_CONDITION This error is returned because some data adapters' ORM return full table data by default when they receive an empty condition, which tends to behave contrary to expectations.(e.g. GORM) If you are using an adapter that does not behave like this, you can choose to ignore this error.

conditions, err := e.GetAllowedObjectConditions("alice", "read", "r.obj.")

var conditions = e.GetAllowedObjectConditions("alice", "read", "r.obj.");

`GetImplicitUsersForResource()`

Returns all users with access to a resource, including those with implicit permissions through roles.

For example:

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

GetImplicitUsersForResource("data2") will return [["bob", "data2", "write"], ["alice", "data2", "read"] ["alice", "data2", "write"]], nil.

GetImplicitUsersForResource("data1") will return [["alice", "data1", "read"]], nil.

ImplicitUsers, err := e.GetImplicitUsersForResource("data2")

var implicitUsers = e.GetImplicitUsersForResource("data2");

노트

Only users will be returned, roles (2nd arg in "g") will be excluded.

`GetNamedImplicitUsersForResource()`

Returns all users with access to a resource through a named policy, including those with implicit permissions through roles. This function handles resource role relationships through named policies (e.g., g2, g3, etc.).

For example:

p, admin_group, admin_data, *
g, admin, admin_group
g2, app, admin_data

GetNamedImplicitUsersForResource("g2", "app") will return users who have access to admin_data through g2 relationship.

ImplicitUsers, err := e.GetNamedImplicitUsersForResource("g2", "app")

var implicitUsers = e.GetNamedImplicitUsersForResource("g2", "app");
