jwt官网：https://jwt-auth.readthedocs.io/en/develop/
1. 安装laravel
laravel new
2. 安装jwt
tymon / jwt-auth(https://packagist.org/packages/tymon/jwt-auth)到这个网址获取最新的候选版本 例如：1.0.0.rc-3 下载jwt
composer require tymon/jwt-auth 1.0.0.rc-3
3.生成config/jwt.php
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
3.生成密钥
php artisan jwt:secret
4.创建模型
<?php
namespace App\Model;
use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class Admin extends Authenticatable implements JWTSubject
{
protected $table = 'Admin';
use Notifiable;
// 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 [];
}
}
5.配置Auth防护
在config/auth.php文件内部
<?php
return [
/*
|--------------------------------------------------------------------------
| Authentication Defaults
|--------------------------------------------------------------------------
|
| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults
| as required, but they're a perfect start for most applications.
|
*/
'defaults' => [
'guard' => 'admin',
'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
| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session", "token"
|
*/
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'admin' => [
'driver' => 'jwt',
'provider' => 'admin',
],
],
/*
|--------------------------------------------------------------------------
| User Providers
|--------------------------------------------------------------------------
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple
| sources which represent each model / table. These sources may then
| be assigned to any extra authentication guards you have defined.
|
| Supported: "database", "eloquent"
|
*/
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
'admin' => [
'driver' => 'eloquent',
'model' => App\Model\Admin::class,
],
// 'users' => [
// 'driver' => 'database',
// 'table' => 'users',
// ],
],
/*
|--------------------------------------------------------------------------
| Resetting Passwords
|--------------------------------------------------------------------------
|
| You may specify multiple password reset configurations if you have more
| than one user table or model in the application and you want to have
| separate password reset settings based on the specific user types.
|
| The expire time is the number of minutes that the reset token should be
| considered valid. This security feature keeps tokens short-lived so
| they have less time to be guessed. You may change this as needed.
|
*/
'passwords' => [
'users' => [
'provider' => 'users',
'table' => 'password_resets',
'expire' => 60,
],
],
];
6.添加路由routes/api.php如下：
<?php
use Illuminate\Http\Request;
/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
Route::group([
'middleware' => 'api',
'prefix' => 'auth'
], function ($router) {
Route::post('login', 'AuthController@login');
Route::post('logout', 'AuthController@logout');
Route::post('refresh', 'AuthController@refresh');
Route::post('me', 'AuthController@me');
});
7.创建AuthController
php artisan make:controller AuthController
然后添加以下内容：
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;
class AuthController extends Controller
{
/**
* Create a new AuthController instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('auth:admin', ['except' => ['login']]);
}
/**
* Get a JWT via given credentials.
*
* @return \Illuminate\Http\JsonResponse
*/
public function login()
{
$credentials = request(['username', 'password']);
if (! $token = auth()->attempt($credentials)) {
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()->user());
}
/**
* Log the user out (Invalidate the token).
*
* @return \Illuminate\Http\JsonResponse
*/
public function logout()
{
auth()->logout();
return response()->json(['message' => 'Successfully logged out']);
}
/**
* Refresh a token.
*
* @return \Illuminate\Http\JsonResponse
*/
public function refresh()
{
return $this->respondWithToken(auth()->refresh());
}
/**
* Get the token array structure.
*
* @param string $token
*
* @return \Illuminate\Http\JsonResponse
*/
protected function respondWithToken($token)
{
return response()->json([
'access_token' => $token,
'token_type' => 'bearer',
'expires_in' => auth()->factory()->getTTL() * 60
]);
}
}
8.数据库
1.创建数据库，创建一个至少有账号-密码2个字段的表
2.修改App.env文件中数据库-账号-密码-名称
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=login //数据库名称
DB_USERNAME=root //数据库账号
DB_PASSWORD= //密码
9.Postman 调试
1.下载Postman
到https://www.getpostman.com/downloads/下载Postman
image.png
2.调试
打开Postman后设置：
3JC~${3(5VD550)6O(UGK2H.png
登录正确后会返回access_token，复制他

调试完成！
