laravel8-使用jwt

jwt-官方网址
https://jwt-auth.readthedocs.io/en/develop/laravel-installation

安装

• 第一步：composer拉取最新版本

composer require tymon/jwt-auth

• 第二步：添加服务提供者（Laravel 5.4 或以下）
  将服务提供者添加到配置文件 config/app.php 中的 providers 数组中，如下所示：

'providers' => [

    ...
    
    Tymon\JWTAuth\Providers\LaravelServiceProvider::class,
]

'aliases' => [
		...
		
        'JWTAuth' => Tymon\JWTAuth\Facades\JWTAuth::class,
        'JWTFactory' => Tymon\JWTAuth\Facades\JWTFactory::class,
    ],

• 第三步：运行以下命令发布包配置文件

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

运行完后应该有一个 config/jwt.php 文件，允许配置此包的基础知识

• 第四步：运行以下命令生成一个密钥

php artisan jwt:secret

运行完后.env文件会生成一个 JWT_SECRET

在laravel项目中配置

• 第一步：配置 config/auth.php
  在 config/auth.php 中，将 api 的 driver 驱动改为 jwt
  
  然后注册自己写的model
  
  - 第二步：定义路由
  
  具体代码
  - 控制器-新建 AuthController

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Support\Facades\Auth;
use Tymon\JWTAuth\Facades\JWTAuth;

class AuthController extends Controller
{
    
    /** * Create a new AuthController instance. * * @return void */
    public function __construct()
    {
    
        $this->middleware('auth:api', ['except' => ['login']]);
    }

    /** * Get a JWT via given credentials. * * @return \Illuminate\Http\JsonResponse */
    public function login(Request $request)
    {
    
        $credentials = $request->only('name', 'password');

        if (count($credentials) < 2) {
    
            return response()->json(['error' => 'Unauthorized'], 401);
        }

        $user = User::where('name', $credentials['name'])
            ->where('password', ($credentials['password']))
            ->first();

        if (empty($user) || !$token = JWTAuth::fromUser($user)) {
    
            return response()->json(['error' => 'Unauthorized'], 401);
        }

        return $this->respondWithToken($token);

    }

    /** * Get the authenticated User. * * @return \Illuminate\Http\JsonResponse */
    public function me()
    {
    
        return response()->json(auth('api')->user());
    }

    /** * Log the user out (Invalidate the token). * * @return \Illuminate\Http\JsonResponse */
    public function logout()
    {
    
        auth('api')->logout();

        return response()->json(['message' => 'Successfully logged out']);
    }

    /** * Refresh a token. * @return \Illuminate\Http\JsonResponse */
    public function refresh()
    {
    
        return $this->respondWithToken(auth('api')->refresh());
    }

    /** * Get the token array structure. * * @param string $token * * @return \Illuminate\Http\JsonResponse */
    protected function respondWithToken($token)
    {
    
        return response()->json([
            'access_token' => $token,
            'token_type' => 'bearer',
            'expires_in' => auth('api')->factory()->getTTL() * 60
        ]);
    }
}

- Model-新建 User

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements JWTSubject
{
    
    use Notifiable;

    protected $table = 'users';

    // Rest omitted for brevity

    /** * 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 [];
    }
}

end-到此结束
