[开发测试]laravel8 实现接口鉴权封装使用JWT

1.camposer 安装JWT类

composer require firebase/php-jwt

2.在App文件下新建Server文件夹，新建JwtServer类

?3.类中写入以下代码

<?php


namespace App\Server;
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
use phpDocumentor\Reflection\Types\False_;

class JwtServer
{
    public static function createToken($userId)
    {
        $key = "example_key";
        $payload = array(
            "iss" => "http://example.org",
            "aud" => "http://example.com",
            "iat" => 1356999524,
            "nbf" => 1357000000,
            'user_id'=>$userId
        );
        $jwt = JWT::encode($payload, $key, 'HS256');
        return $jwt;
    }
    public static function decodeToken($jwt){
        $key = "example_key";
        $decoded = JWT::decode($jwt, new Key($key, 'HS256'));
        if ($decoded){
            return $decoded;
        }else{
            return  false;
        }

    }
}

4.新建中间件

php artisan make:middleware CheckApiLogin

5.在中间件中写入 ，将token放入header中传输

    public function handle(Request $request, Closure $next)
    {
        //将token放入header中传输
        $token=$request->header('token');
        if (!$token){
            return response()->json(['code'=>500,'msg'=>'token不存在','data'=>[]]);
        }
        $userId=JwtServer::decodeToken($token);
        if ($userId){
            //将加密id解密传入下一步
            $request->attributes->add(['user_id'=>$userId]);
        }else{
            return response()->json(['code'=>500,'msg'=>'token过期','data'=>[]]);
        }
        return $next($request);
    }

6.注册中间件

'checkApiLogin' => \App\Http\Middleware\CheckApiLogin::class

7.在路由中使用中间件

Route::group(['middleware'=>'checkApiLogin'],function (){
    
    
});

?

8.获取token解密的凭证这里使用的是userId

    public function index(Request $request)
    {
        $userId=$request->get('user_id');
        
    }
