Authz PHP SDK

This is the Authz development kit for PHP.

Installation

You can install the SDK in your project by adding the following dependency:

$ composer require eko/authz-sdk

⚠️ Please note that you will need to install the grpc PHP extension.

Usage

You have to instanciate a new Authz Client in your code by doing:

<?php
use Eko\AuthzSdk\Client;

$client = new Client('localhost:8081', '<client_id>', '<client_secret>');

Once the client is instanciate, you have access to all the gRPC methods.

In order to create a new Principal, you can use

[$response, $status] = $client->PrincipalCreate(new PrincipalCreateRequest([
    'id' => 'user-123',
    'attributes' => [
        new Attribute(['key' => 'email', 'value' => 'johndoe@acme.tld']),
    ],
]))->wait();

To declare a new resource:

[$response, $status] = $client->ResourceCreate(new ResourceCreateRequest([
    'id' => 'post.123',
    'kind' => 'post',
    'value' => '123',
    'attributes' => [
        new Attribute(['key' => 'owner_email', 'value' => 'johndoe@acme.tld']),
    ],
]))->wait();

You can also declare a new policy this way:

[$response, $status] = $client->PolicyCreate(new PolicyCreateRequest([
    'id' => 'post-owners',
    'resources' => ['post.*'],
    'actions' => ['edit', 'delete'],
    'attribute_rules' => [
        'principal.email == resource.owner_email',
    ],
]))->wait();

Then, you can perform a check with:

if ($client->IsAllowed('user-123', 'post', '123', 'edit')) {
    // Do something
}

Please note that you have access to all the gRPC methods declared here in the proto file.
