1.创建中间件OAuthOperationCenter.php

2.\`<?php

namespace App\\Middleware;

use Closure;  
use App\\Tools\\OperationCenter\\Token;  
use Illuminate\\Support\\Facades\\Redis as RedisClient;

class OAuthOperationCenter  
\{  
/\*\*  
\* TOKEN\_KEY string  
\*/  
private const TOKEN\_KEY = “-OPERATION-CENTER-TOEKN”;

/**
     * @var string
     */
    protected $token;
    
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if ( !array_key_exists('authorization',$request->header()) ){
            error('400','缺少authorization参数');
        }
        if ( empty($request->header()['authorization']) ){
            error('400','authorization参数值不能为空');
        }
        $this->token = $request->header('authorization');
        $this->token= trim(ltrim($this->token,'Bearer'));
        $userInfo = Token::decodeToken($this->token);
        $userRedis = RedisClient::get($userInfo['username'].self::TOKEN_KEY);
        if ( empty($userRedis) ){
            error('403','您还未登录,请先登录','Unauthorized');
        }
        return $next($request);
    }

\}  
\`

Token.php

<?php
    /** * Created by PhpStorm. * Date: 20-8-26 * Time: 下午3:51 */
    namespace App\Tools\OperationCenter;
    
    
    
    class Token
    { 
    
    
        /** * Notes:生成token * Date: 20-8-26 * Time: 下午4:09 * @param $data * @return string */
        public static function enableToken($data) : string
        { 
            return  base64_encode(json_encode($data,512));
        }
    
        /** * Date: 20-8-26 * Time: 下午4:08 * @param $data * @return array */
        public static function decodeToken($data) : array
        { 
            return json_decode( base64_decode(str_replace(" ","+",$data)),true);
        }
    
    
    
    
    }
