ThinkPHP5实现JWT Token认证的过程(亲测可用)

<?php
use Lcobucci\JWT\Builder;
use Lcobucci\JWT\signer\Hmac\Sha256;

class Token{
	//自定义一个生成token的方法
	static public function createToken($uid = null){
		$signer = new Sha256(;//加密算法
		$time = time(;//当前的时间戳
		$token = (new Builder())
			->issuedBy( issuer: "fanxinze')//配置发行人
			->canonlyBeUsedBy( audience: " user')//配置接收人
			->identifiedBy( id: ' quanzhankaifa',replicateAsHeader: true)//标题id->issuedAt($time)//发出token令牌的时间
			->canonlyBeUsedAfter( notBefore: $time + 60)//生效时间->expiresAt( expiration: $time + 3600)//过期时间
			->with( name: " uid' , $uid)//用户id
			->sign($signer, key: ' 1902a" )//签名内容->getToken(;//获取token
		return (string)$token;
	}
}

<?php
namespace app\index\controller;
use think\Controller;
use Token;

class Index extends Controller
{
	public function index()
	{
	$token = Token : : createToken();
	return $token;
	}
}

//验证token
static public function verifyToken($token=null){
	//检测是否接收到了token
	if(empty($token)){
		return 0;
	}
	//代码到50行，就表示取到token了，那么转化成jwt认识的token
	$token = (new Parser())->parse((string) $token);
	//验证基本设置
	$data = new ValidationData();
	$data->setIssuer( issuer: "teacher ' );
	$data->setAudience( audience: 'student ' );$data->setId( id: " quanzhan ' );
	if(!$token->validate($data)){

	}
	//验证签名
	$signer = new sha256();
	if(!$token->verify($signer, key: ' 1902a' )){
	return 0;
	}
	//验证通过，返回用户id
	return $token->getclaim( name:'uid');
}

//登录
