1.引入php-jwt包

composer require firebase/php-jwt

2.代碼

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 {/*** 根據json web token設置的規則生成token* @return \think\response\Json*/public function createjwt(){$key = md5('dd'); //jwt的簽發密鑰，驗證token的時候需要用到$time = time(); //簽發時間$expire = $time + 14400; //過期時間$token = array("user_id" => 1,"iss" => "http://www.najingquan.com/",//簽發組織"aud" => "zz", //簽發作者"iat" => $time,"nbf" => $time,"exp" => $expire);$jwt = JWTUtil::encode($token,$key);return show(1,"OK",$jwt);}/*** 驗證token* @return \think\response\Json*/public function verifyjwt(){$jwt= input("jwt");$key = md5('dd'); //jwt的簽發密鑰，驗證token的時候需要用到try{$jwtAuth = json_encode(JWTUtil::decode($jwt,$key,array("HS256")));$authInfo = json_decode($jwtAuth,true);if (!$authInfo['user_id']){return show(0,"用戶不存在");}return show(0,"ok");}catch (ExpiredException $e){return show(0,"token過期");}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");

3.效果如圖所示

圖1.生成token
