Laravel 11 JSON Web Token(JWT) API Authentication教程

在这篇文章中,我将向您展示如何在 laravel 11 应用程序中使用 JWT 令牌进行 API 身份验证。我们将从头开始学习 API、JWT REST API 和 Laravel JWT 身份验证,并创建一个示例 API。

什么是

API

API(应用程序编程接口)只是两个或多个计算机程序之间的一种通信方式。

API 还用于 Web 和移动应用程序开发;因此,构建 REST API 对于任何 Web 和移动应用程序开发人员都非常重要。

什么是

JWT

JWT 代表 JSON Web 令牌,它是一个开放标准(RFC 7519),它定义了一种紧凑且自包含的方式,用于将信息作为 JSON 对象在各方之间安全地传输。JWT 通常用于授权、信息交换等。

在此示例中,我们将安装 Laravel 11 应用程序。然后,我们将安装

api

。然后我们将使用

php-open-source-saver/jwt-auth

包来使用

JWT

。之后,我们将创建用于用户身份验证的 register、login、refresh、profile 和 logout API。那么,让我们按照以下步骤逐步完成此示例:

按照以下几个步骤在 laravel 11 应用程序中创建一个 restful API 示例。

第一步: 安装 Laravel 11

如果已经安装可以忽略;如果您尚未创建

Laravel

应用程序,则可以继续执行以下命令:

composer create-project laravel/laravel example-app

第二步:启用 API 并更新身份验证

默认情况下,laravel 11 API 路由在 laravel 11 中未启用。我们将使用以下命令启用 API:

php artisan install:api

现在,如果用户未进行身份验证,则

exception

将调用,我们将返回

json

响应。那么,让我们更新

app.php

文件。

bootstrap/app.php

<?php

use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;
use Illuminate\Auth\AuthenticationException;
use Illuminate\Http\Request;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        api: __DIR__.'/../routes/api.php',
        commands: __DIR__.'/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        //
    })
    ->withExceptions(function (Exceptions $exceptions) {
        $exceptions->render(function (AuthenticationException $e, Request $request) {
            if ($request->is('api/*')) {
                return response()->json([
                    'message' => $e->getMessage(),
                ], 401);
            }
        });
    })->create();

安装和设置 JWT Auth 软件包

在此步骤中,我们将安装 php-open-source-saver/jwt-auth composer 包。

composer require php-open-source-saver/jwt-auth

包配置文件:

php artisan vendor:publish --provider="PHPOpenSourceSaver\JWTAuth\Providers\LaravelServiceProvider"

接下来,生成密钥。这将在 .env 文件上添加 JWT 配置值:

php artisan jwt:secret

现在,我们将更新 Auth Guard 配置文件。

config/auth.php

<?php
return [

    /*
    |--------------------------------------------------------------------------
    | Authentication Defaults
    |--------------------------------------------------------------------------
    |
    | This option defines the default authentication "guard" and password
    | reset "broker" for your application. You may change these values
    | as required, but they're a perfect start for most applications.
    |
    */

    'defaults' => [
        'guard' => 'api',
        'passwords' => 'users',
    ],

    /*
    |--------------------------------------------------------------------------
    | Authentication Guards
    |--------------------------------------------------------------------------
    |
    | Next, you may define every authentication guard for your application.
    | Of course, a great default configuration has been defined for you
    | which utilizes session storage plus the Eloquent user provider.
    |
    | All authentication guards have a user provider, which defines how the
    | users are actually retrieved out of your database or other storage
    | system used by the application. Typically, Eloquent is utilized.
    |
    | Supported: "session"
    |
    */

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
    ],

    ...

更新 User 模型

在该模型中,我们首先在用户模型上实现

Tymon\JWTAuth\Contracts\JWTSubject

合约,然后实现

getJWTIdentifier()

getJWTCustomClaims()

方法。

app/Models/User.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use PHPOpenSourceSaver\JWTAuth\Contracts\JWTSubject; 

class User extends Authenticatable implements JWTSubject
{
    use HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * Get the attributes that should be cast.
     *
     * @return array
     */
    protected function casts(): array
    {
        return [
            'email_verified_at' => 'datetime',
            'password' => 'hashed',
        ];
    }

    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }
 
    /**
     * Return a key value array, containing any custom claims to be added to the JWT.
     *
     * @return array
     */
    public function getJWTCustomClaims()
    {
        return [];
    }
}

创建 API 路由

在此步骤中,我们将创建 API 路由。Laravel 提供了用于编写 Web 服务路由的 api.php 文件。因此,让我们向该文件添加新路由。

routes/api.php

<?php

use Illuminate\Support\Facades\Route;
 
Route::group([
    'middleware' => 'api',
    'prefix' => 'auth'
], function ($router) {
    Route::post('/register', [App\Http\Controllers\Api\AuthController::class, 'register']);
    Route::post('/login', [App\Http\Controllers\Api\AuthController::class, 'login']);
    Route::post('/logout', [App\Http\Controllers\Api\AuthController::class, 'logout'])->middleware('auth:api');
    Route::post('/refresh', [App\Http\Controllers\Api\AuthController::class, 'refresh'])->middleware('auth:api');
    Route::post('/profile', [App\Http\Controllers\Api\AuthController::class, 'profile'])->middleware('auth:api');
});

创建 Controller 文件

在下一步中,我们创建了一个名为

Controller

AuthController

的新控制器。我在 Controllers 文件夹中创建了一个名为 “Api” 的新文件夹,因为我们将为 API 提供单独的控制器。所以,让我们创建两个控制器:

app/Http/Controllers/Api/Controller.php

<?php
namespace App\Http\Controllers\Api;

abstract class Controller
{
    /**
     * success response method.
     *
     * @return \Illuminate\Http\Response
     */
    public function sendResponse($result, $message)
    {
        $response = [
            'success' => true,
            'data'    => $result,
            'message' => $message,
        ];
 
        return response()->json($response, 200);
    }
 
    /**
     * return error response.
     *
     * @return \Illuminate\Http\Response
     */
    public function sendError($error, $errorMessages = [], $code = 404)
    {
        $response = [
            'success' => false,
            'message' => $error,
        ];
 
        if(!empty($errorMessages)){
            $response['data'] = $errorMessages;
        }
 
        return response()->json($response, $code);
    }
}

app/Http/Controllers/Api/AuthController.php

<?php

namespace App\Http\Controllers\Api;
  
use App\Models\User;
use Validator;
use Illuminate\Http\Request;
  
class AuthController extends Controller
{
 
    /**
     * Register a User.
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function register(Request $request) {

        $validator = Validator::make($request->all(), [
            'name' => 'required',
            'email' => 'required|email',
            'password' => 'required',
            'c_password' => 'required|same:password',
        ]);
     
        if($validator->fails()){
            return $this->sendError('Validation Error.', $validator->errors());       
        }
     
        $input = $request->all();
        $input['password'] = bcrypt($input['password']);
        $user = User::create($input);
        $success['user'] =  $user;
   
        return $this->sendResponse($success, 'User register successfully.');
    }
  
  
    /**
     * Get a JWT via given credentials.
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function login()
    {
        $credentials = request(['email', 'password']);
  
        if (! $token = auth()->attempt($credentials)) {
            return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
        }
  
        $success = $this->respondWithToken($token);
   
        return $this->sendResponse($success, 'User login successfully.');
    }
  
    /**
     * Get the authenticated User.
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function profile()
    {
        $success = auth()->user();
   
        return $this->sendResponse($success, 'Refresh token return successfully.');
    }
  
    /**
     * Log the user out (Invalidate the token).
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function logout()
    {
        auth()->logout();
        
        return $this->sendResponse([], 'Successfully logged out.');
    }
  
    /**
     * Refresh a token.
     *
     * @return \Illuminate\Http\JsonResponse
     */
    public function refresh()
    {
        $success = $this->respondWithToken(auth()->refresh());
   
        return $this->sendResponse($success, 'Refresh token return successfully.');
    }
  
    /**
     * Get the token array structure.
     *
     * @param  string $token
     *
     * @return \Illuminate\Http\JsonResponse
     */
    protected function respondWithToken($token)
    {
        return [
            'access_token' => $token,
            'token_type' => 'bearer',
            'expires_in' => auth()->factory()->getTTL() * 60
        ];
    }
}

所有必需的步骤都已完成,现在您必须键入以下给定的命令并按 Enter 键以运行 Laravel 应用程序:

php artisan serve

现在,转到您的

Postman

并检查以下

API

请确保在详细信息

API

中,我们将使用如下所示的请求头,登陆和注册除外:

'headers' => [
    'Accept' => 'application/json',
    'Authorization' => 'Bearer '.$accessToken,
]
