thinkphp6集成JWT_thinkphp6 lcobucci-优快云博客

1.引入php-jwt包

使用composer安装 JWT 功能组件

# 安装
composer require lcobucci/jwt 3.3

2.封装JWT工具类 (参考 GitHub - lcobucci/jwt at 3.3)

Route::group('goods',function (){
    Route::resource('blog','Login');
})->middleware(\app\admin\middleware\Login::class);

3.代码

建立（controller同级）：extend/tools/jwt/Token.php

{
    private static $_config = [
        'audience' => 'http://www.pyg.com',//接收人

        $method = 'bearer';
        //去除token中可能存在的bearer标识
        return trim(str_ireplace($method, '', $header));
    }

    //从token中获取用户id （包含token的校验）
    public static function getUserId($token = null)
    {
        $user_id = null;

        $token = empty($token)?self::getRequestToken():$token;

        if (!empty($token)) {
            //为了注销token 加以下if判断代码
            $delete_token = cache('delete_token') ?: [];
            if(in_array($token, $delete_token)){
                //token已被删除（注销）
                return $user_id;
            }
            $token = (new Parser())->parse((string) $token);
            //验证token
            $data = new ValidationData();
            $data->setIssuer(self::$_config['issuer']);//验证的签发人
            $data->setAudience(self::$_config['audience']);//验证的接收人
            $data->setId(self::$_config['id']);//验证token标识

            if (!$token->validate($data)) {
                //token验证失败
                return $user_id;
            }

            //验证签名
            $signer = new Sha256();
            if (!$token->verify($signer, self::$_config['sign'])) {
                //签名验证失败
                return $user_id;
            }
            //从token中获取用户id
            $user_id = $token->getClaim('user_id');
        }

        return $user_id;
    }
}

4.测试

静态调用封装的\tools\jwt\Token类的getToken方法，传递一个用户id值，生成token

静态调用封装的\tools\jwt\Token类的getUserId方法，传递一个token，获取用户id值

$data = [
       $token = Token::getToken($obj->id)
];

5.效果图

鉴权登录
