JWT使用流程
初次登录：用户初次登录，输入用户名密码
密码验证：服务器从数据库取出用户名和密码进行验证
生成JWT：服务器端验证通过，根据从数据库返回的信息，以及预设规则，生成JWT
返还JWT：服务器的HTTP RESPONSE中将JWT返还
带JWT的请求：以后客户端发起请求，HTTP REQUEST
HEADER中的Authorizatio字段都要有值，为JWT
服务器验证JWT
安装
// 安装jwt最新版本
composer require tymon/jwt-auth 1.0.0-rc.2
// 发布配置文件
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
// 生成密钥
php artisan jwt:secret
配置Model和Controller
设置模型文件 User.php 的内容如下：
<?php
namespace App;
use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable implements JWTSubject
{
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 [];
}
}
创建权限控制器
php artisan make:controller AuthController
更新控制器内容：
<?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:api', ['except' => ['login']]);
}
/**
* Get a JWT via given credentials.
*
* @return \Illuminate\Http\JsonResponse
*/
public function login()
{
$credentials = request(['email', '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' => $token,
'token_type' => 'bearer',
'expires_in' => auth()->factory()->getTTL() * 60
]);
}
}
配置守卫和路由
配置config/auth.php
'defaults' => [
'guard' => 'api',
'passwords' => 'users',
],
...
'guards' => [
'api' => [
'driver' => 'jwt',
'provider' => 'users',
],
],
配置routes/api.php
Route::group([
'middleware' => 'api',
'prefix' => 'auth'
], function ($router) {
Route::post('login', 'AuthController@login');
Route::post('logout', 'AuthController@logout');
Route::post('refresh', 'AuthController@refresh');
Route::post('me', 'AuthController@me');
});
你现在应该可以通过post登录（例如：http://example.dev/auth/login）得到如下响应:
{
"access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ",
"token_type": "bearer",
"expires_in": 3600
}
验证请求
一下有几种途径发送token
Authorization 头信息
Authorization: Bearer eyJhbGciOiJIUzI1NiI...
url查询参数
http://example.dev/me?token=eyJhbGciOiJIUzI1NiI...
