composer install

composer require linwanfeng/jwt-php --no-update

composer update linwanfeng/jwt-php

生成token

<?php
use \JwtPhp\Jwt;
$jwt = new Jwt();
//生成签名
$jwt->setSecret("xDE}o4L1dVW+'@;P#=9]SFvVzPs'~Z");//设置密钥
$jwt->setExp(time()-1);
$jwt->setIat(time()-2);
try {
    $jwt->setPublicPd(['username' => 'linwanfeng', 'luserid' => 'Ahkjhkgusd']);//设置公共信息
    $b = $jwt->genSignature();//生成jwt字符串
} catch (Exception $e) {
    echo "必须传数组";
}

验证jwt字符串的真实性

try {
    $a = $jwt->vailDecSign("sdhlshadhsaidhhhhhhhhhhhhhhhhhhhhhhhhhhhhhsaidh.sadsadsad.saddssssssssssssssssssssss");
} catch (Exception $e) {
}
if ($a===true) {
    echo "验证通过";
}

验证签名是否过期

$exp = $jwt->isExp();//调用此方法之前必须验证token真实性,return true or false
if ($exp) {
    echo "token未过期";
} else {
    echo "token已过期";
}

获取payload信息

$jwt->getRecPd();//获取全部信息
$jwt->getRecPd('username');//获取某个字段信息
