This article introduces the relevant knowledge of "PHP uses Casbin to do RBAC and RESTful access control". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

PHP-Casbin is a powerful and efficient open source access control framework that supports rights management based on various access control models (RBAC ABAC ACL).

Here use the official database adapter extension: DBAL Adapter.

Installation

Install via composer:

Composer require casbin/casbincomposer require casbin/dbal-adapter uses RBAC Model

Model.conf is as follows:

[request_definition] r = sub, obj, act [policy _ definition] p = sub, obj, act# RBAC definition of role inheritance relationship [role_definition] g = _, _ [policy_effect] e = some (where (p.eft = = allow)) [matchers] m = g (r.sub, p.sub) & & keyMatch3 (r.obj, p.obj) & & regexMatch (r.act, p.act) initializes a Casbin enforceruse Casbin\ Enforcer;use CasbinAdapter\ DBAL\ Adapter $adapter = Adapter::newAdapter (['driver' = >' pdo_mysql', 'host' = >' 127.0.0.1 policies, 'dbname' = >' test', 'user' = >' root', 'password' = >', 'port' = >' 3306 policies,]); $enforcer = new Enforcer ('path/to/model.conf', $adapter); add policies

Assign roles to alice and bob:

/ / alice has the admin role$enforcer- > addRoleForUser ('alice',' admin'); / / bob has the member role$enforcer- > addRoleForUser ('bob',' member')

Assign permissions to the member role, and the member role only has permission to view foo resources:

$enforcer- > addPermissionForUser ('member',' / foo', 'GET'); $enforcer- > addPermissionForUser (' member','/ foo/:id', 'GET')

The admin role has the permission to add, delete, modify and query foo:

/ / admin inherits all permissions of member$enforcer- > addRoleForUser ('admin',' member'); $enforcer- > addPermissionForUser ('admin',' / foo', 'POST'); $enforcer- > addPermissionForUser (' admin','/ foo/:id', 'PUT'); $enforcer- > addPermissionForUser (' admin','/ foo/:id', 'DELETE')

After the roles and permissions are assigned, the policy rules in the database are roughly as follows:

G, alice, adming, bob, memberp, memeber, / foo, GETp, memeber, / foo/:id, GETg, admin, memberp, admin, / foo, POSTp, admin, / foo/:id, PUTp, admin, / foo/:id, DELETE authentication permissions

Alice has the admin role and inherits all permissions of admin and member roles.

$enforcer- > enforce ('alice',' / foo', 'GET'); / / true$enforcer- > enforce (' alice','/ foo', 'GET'); / / true$enforcer- > enforce (' alice','/ foo', 'POST'); / / true$enforcer- > enforce (' alice','/ foo/1', 'PUT'); / / true$enforcer- > enforce (' alice','/ foo/1', 'DELETE'); / / true

Bob has the role of member and inherits only the permissions of member.

Enforcer- > enforce ('bob',' / foo', 'GET'); / / true$enforcer- > enforce (' bob','/ foo', 'GET'); / / true$enforcer- > enforce (' bob','/ foo', 'POST'); / / false$enforcer- > enforce (' bob','/ foo/1', 'PUT'); / / false$enforcer- > enforce (' bob','/ foo/1', 'DELETE') / / false, this is the end of the introduction of "PHP's method of using Casbin to do RBAC and RESTful access control".
