laravel 安裝jwt-auth及驗證
1、使用composer安裝jwt， cmd到專案資料夾中；
composer require tymon/jwt-auth 1.0.*（這裡版本號碼依自己的需求寫）
安裝jwt ，參考官方文件https: //jwt-auth.readthedocs.io/en/docs/laravel-installation/
2、如果laravel版本低於5.4
開啟根目錄下的config/app. php
在'providers'陣列裡加上Tymon\JWTAuth\Providers\LaravelServiceProvider::class,
'providers' => [ ... Tymon\JWTAuth\Providers\LaravelServiceProvider:: class,]
3、在config 下增加一個jwt.php 的設定檔
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
4、在.env 檔案下產生一個加密金鑰，如：JWT_SECRET=foobar
php artisan jwt:secret
5、在user模型中寫入下列程式碼
<?php
namespace App\Model;
use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable implements JWTSubject
{
// Rest omitted for brevity
protected $table="user";
public $timestamps = false;
public function getJWTIdentifier()
{
return $this->getKey();
}
public function getJWTCustomClaims()
{
return [];
}
}6、註冊兩個Facade
config/app.php
'aliases' => [
...
// 添加以下两行
'JWTAuth' => 'Tymon\JWTAuth\Facades\JWTAuth',
'JWTFactory' => 'Tymon\JWTAuth\Facades\JWTFactory',
],7、修改auth.php
config/auth.php
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'jwt', // 原来是 token 改成jwt
'provider' => 'users',
],
],8、註冊路由
Route::group([
'prefix' => 'auth'
], function ($router) {
$router->post('login', 'AuthController@login');
$router->post('logout', 'AuthController@logout');
});9、建立token控制器
php artisan make:controller AuthController
##程式碼如下：<?php
namespace App\Http\Controllers;
use App\Model\User;
use Illuminate\Http\Request;
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()
{
$credentials = request(['email', 'password']);
if (! $token = auth('api')->attempt($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(JWTAuth::parseToken()->touser());
}
/**
* Log the user out (Invalidate the token).
*
* @return \Illuminate\Http\JsonResponse
*/
public function logout()
{
JWTAuth::parseToken()->invalidate();
return response()->json(['message' => 'Successfully logged out']);
}
/**
* Refresh a token.
*
* @return \Illuminate\Http\JsonResponse
*/
public function refresh()
{
return $this->respondWithToken(JWTAuth::parseToken()->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' => JWTAuth::factory()->getTTL() * 60
]);
}
}<?php
namespace App\Http\Middleware;
use Auth;
use Closure;
use Tymon\JWTAuth\Exceptions\JWTException;
use Tymon\JWTAuth\Http\Middleware\BaseMiddleware;
use Tymon\JWTAuth\Exceptions\TokenExpiredException;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
// 注意，我们要继承的是 jwt 的 BaseMiddleware
class RefreshToken extends BaseMiddleware
{
/**
* Handle an incoming request.
*
* @ param \Illuminate\Http\Request $request
* @ param \Closure $next
*
* @ throws \Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException
*
* @ return mixed
*/
public function handle($request, Closure $next)
{
// 检查此次请求中是否带有 token，如果没有则抛出异常。
$this->checkForToken($request);
// 使用 try 包裹，以捕捉 token 过期所抛出的 TokenExpiredException 异常
try {
// 检测用户的登录状态，如果正常则通过
if ($this->auth->parseToken()->authenticate()) {
return $next($request);
}
throw new UnauthorizedHttpException('jwt-auth', '未登录');
} catch (TokenExpiredException $exception) {
// 此处捕获到了 token 过期所抛出的 TokenExpiredException 异常，我们在这里需要做的是刷新该用户的 token 并将它添加到响应头中
try {
// 刷新用户的 token
$token = $this->auth->refresh();
// 使用一次性登录以保证此次请求的成功
Auth::guard('api')->onceUsingId($this->auth->manager()->getPayloadFactory()->buildClaimsCollection()->toPlainArray()['sub']);
} catch (JWTException $exception) {
// 如果捕获到此异常，即代表 refresh 也过期了，用户无法刷新令牌，需要重新登录。
throw new UnauthorizedHttpException('jwt-auth', $exception->getMessage());
}
}
// 在响应头中返回新的 token
return $this->setAuthenticationHeader($next($request), $token);
}
}$request->headers->set('Authorization','Bearer '.$token);
'RefreshToken' => \App\Http\Middleware\RefreshToken::class,
Route::group(['prefix' => 'user'],function($router) {
$router->get('userInfo','UserController@userInfo')->middleware('RefreshToken');
