安装

使用composer管理依赖项并下载PHP-JWT：

composer require firebase/php-jwt

示例 1

<?php
// 北京时间
date_default_timezone_set("PRC");
require_once "vendor/autoload.php";

use \Firebase\JWT\JWT;

$key = "sdqazxsw2@)!<<+";
$time = time();
$token = [
    "iss" => "user_center",// 签发者
    "aud" => "full_platform",// 面向的用户
    "iat" => $time,// 签发时间
//    "nbf" => $time + 5,// 在什么时间之后该jwt才可用
    'exp' => $time + 600, // 过期时间-10min
    'data' => [// 自定义数据
        'user_id' => 1001,
        'user_name' => 'xiaoming'
    ]
];

echo "数据:\n" . print_r($token, true) . "\n";

$jwt = JWT::encode($token, $key);
echo "加密:\n" . print_r($token, true) . "\n";

$decoded = JWT::decode($jwt, $key, ['HS256']);
echo "解密:\n" . print_r($decoded, true) . "\n";

输出

 数据:
Array
(
    [iss] => user_center
    [aud] => full_platform
    [iat] => 1551849727
    [exp] => 1551850327
    [data] => Array
        (
            [user_id] => 1001
            [user_name] => xiaoming
        )

)

加密:
Array
(
    [iss] => user_center
    [aud] => full_platform
    [iat] => 1551849727
    [exp] => 1551850327
    [data] => Array
        (
            [user_id] => 1001
            [user_name] => xiaoming
