JWT应用集成

本文介绍JWT应用如何与MaxKey进行集成。

应用注册​

应用在MaxKey管理系统进行注册，注册的配置信息如下

sso_jwt_conf

JWT客户端集成​

本文使用JAVA WEB程序为例

引入客户端所需包​

gson-2.2.4.jar
maxkey-client-sdk.jar
nimbus-jose-jwt-8.10.jar
commons-codec-1.9.jar
commons-io-2.2.jar
commons-logging-1.1.1.jar

获取令牌和用户信息及验证签名​

PHP客户端集成​

引入依赖firebase/php-jwt​

composer require firebase/php-jwt

验证签名​

<?php
require 'vendor/autoload.php';
use \Firebase\JWT\JWT;
use \Firebase\JWT\Key;

$publicKey = <<<EOD
