1.引入php-jwt包
composer require firebase/php-jwt
2.代码
控制器文件:app\api\controller\Jwt.php
<?php
namespace app\api\controller;
use app\BaseController;
use Firebase\JWT\ExpiredException;
use Firebase\JWT\JWT as JWTUtil;
class Jwt extends BaseController
{
/**
* 根据json web token设置的规则生成token
* @return \think\response\Json
*/
public function createjwt()
{
$key = md5('dd'); //jwt的签发密钥,验证token的时候需要用到
$time = time(); //签发时间
$expire = $time + 14400; //过期时间
$token = array(
"user_id" => 1,
"iss" => "http://www.najingquan.com/",//签发组织
"aud" => "zz", //签发作者
"iat" => $time,
"nbf" => $time,
"exp" => $expire
);
$jwt = JWTUtil::encode($token,$key);
return show(1,"OK",$jwt);
}
/**
* 验证token
* @return \think\response\Json
*/
public function verifyjwt()
{
$jwt= input("jwt");
$key = md5('dd'); //jwt的签发密钥,验证token的时候需要用到
try{
$jwtAuth = json_encode(JWTUtil::decode($jwt,$key,array("HS256")));
$authInfo = json_decode($jwtAuth,true);
if (!$authInfo['user_id']){
return show(0,"用户不存在");
}
return show(0,"ok");
}catch (ExpiredException $e){
return show(0,"token过期");
}catch (\Exception $e){
return show(0,$e->getMessage());
}
}
}
路由:app\api\route\api.php
<?php
use think\facade\Route;
Route::rule("jwt","jwt/createjwt","get");
Route::rule("verifyjwt","jwt/verifyjwt","post");
