获取token
<?php
use \Lcobucci\JWT\Builder;
use \Lcobucci\JWT\Signer\Hmac\Sha256;
include "../vendor/autoload.php";
$builder = new Builder();
$signer = new Sha256();
$secret = "suspn@)!*";
//设置header和payload，以下的字段都可以自定义
$builder->setIssuer("suspn.com") //发布者
->setAudience("suspn.com") //接收者
->setId("abc", true) //对当前token设置的标识
->setIssuedAt(time()) //token创建时间
->setExpiration(time() + 60) //过期时间
->setNotBefore(time() + 5) //当前时间在这个时间前，token不能使用
->set('uid', 30061); //自定义数据
//设置签名
$builder->sign($signer, $secret);
//获取加密后的token，转为字符串
$token = (string)$builder->getToken();
var_dump($token);验证token
<?php
use \Lcobucci\JWT\Parser;
