Laravel 11. API Token Authentication

테디아저씨 2026. 5. 15. 21:04

 

 

 

WEB 브라우저 로그인


→ Session 저장
→ 로그인 유지

 

모바일앱 / 외부API

Flutter
React Native
외부 서비스


→ Token 인증

 

 

Session Token
브라우저 중심 앱/API 중심
쿠키 사용 Token 사용
서버 상태 저장 Stateless 가능

 

 

 

 

Laravel Sanctum 

Laravel 공식 API 인증 패키지
Laravel Sanctum

 

install package

composer require laravel/sanctum

 

migration to my project

php artisan vendor:publish --tag=sanctum-migrations

// old version
// php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"

LocalStorage

1. 브라우저에 데이터를 저장하는 웹 저장소(Web Storage) 기능입니다.

2. 페이지를 새로고침하거나 브라우저를 껐다 켜도 데이터가 유지됩니다.

3. 숫자, 객체도 문자열로 변환하여 저장하고, 꺼내서 변환해야 한다.

 

// save
localStorage.setItem('{key}', '{value}');

// load
const keyName = localStorage.getItem('{key}');

// delete
localStorage.removeItem('{key}');

// delete all  :: 도메인별로 구분된다. ( 127.0.0.1:8000, 127.0.0.1:8001 서로 읽거나 쓰지 못함.)
localStorage.clear();



// Object


const user = {
  name: 'teddy',
  age: 20
};

localStorage.setItem('user', JSON.stringify(user));

const user = JSON.parse(localStorage.getItem('user'));

 

로컬스토리지에 토큰저장

save token to local storage ( javascript )

localStorage.setItem('token', data.token);
localStorage.setItem('userName', data.user.name);

로컬스토리지 사용하기

use local storage token

const token = localStorage.getItem('token');
const userName = localStorage.getItem('userName');

 

 

fetch('/api/profile', {
 headers:{
   Authorization:`Bearer ${token}`
 }
})

 

 

delete Token

<script>
    function logout() {
        localStorage.removeItem('token');
        localStorage.removeItem('userName');
        location.href = '/login';
    }
</script>

 

 

Token 으로 사용자 확인

or

 

서버에서도 revoke 가능

 

 

 

보호된 API

Route::middleware('auth:sanctum')->group(function () {
    Route::get('/profile', function (Request $request) {
        return $request->user();
    });
});

 

 

JWT ( Other Token Package )

  • 여러 서버 연동
  • 마이크로서비스
  • 외부 파트너 API
  • SSO 구조

 

 

Sanctum

토큰 → DB 조회 필요

 

JWT

토큰 자체에 정보 포함
DB 조회 없이 검증 가능

 

비유하자면

Sanctum 출입증 번호

JWT 출입증 자체에 정보 내장
