RBAC API

Более дружественный API для RBAC. Этот API является подмножеством Management API. Пользователи RBAC могут использовать этот API для упрощения кода.

Ссылка

Глобальная переменная e является экземпляром Enforcer.

Go

e, err := NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

Node.js

const e = await newEnforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv')

PHP

$e = new Enforcer('examples/rbac_model.conf', 'examples/rbac_policy.csv');

Python

e = casbin.Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

.NET

var e = new Enforcer("path/to/model.conf", "path/to/policy.csv");

Rust

let mut e = Enforcer::new("examples/rbac_model.conf", "examples/rbac_policy.csv").await?;

Java

Enforcer e = new Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv");

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")

Например:

Go

Go

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

.NET

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

.NET

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

GetImplicitObjectPatternsForUser()

GetImplicitObjectPatternsForUser returns all object patterns (with wildcards) that a user has for a given domain and action.

For example:

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

Rust

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

Java

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

GetAllowedObjectConditions()

GetAllowedObjectConditions returns a string array of object conditions that the 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:

0. 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.

1. 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.

Go

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

.NET

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

GetImplicitUsersForResource()

GetImplicitUsersForResource return implicit user based on resource.

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.

Go

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

.NET

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

заметка

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

GetNamedImplicitUsersForResource()

GetNamedImplicitUsersForResource return implicit user based on resource with named policy support. 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.

Go

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

.NET

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