Laravel 框架下多用户分表怎么实现认证

1、服务提供者配置

多用户认证，实现逻辑如下：

'guards' => [
    'admins' => [
        'driver' => 'jwt',
        'provider' => 'admins',
    ],

    'api' => [
        'driver' => 'jwt',
        'provider' => 'students',
    ],
    'teachers' => [
        'driver' => 'jwt',
        'provider' => 'teachers',
    ],
],


'providers' => [
    'admins' => [
        'driver' => 'eloquent',
        'model' => App\Model\Admin::class,
    ],
    'students' => [
        'driver' => 'eloquent',
        'model' => App\Model\Student::class,
    ],
    'teachers' => [
        'driver' => 'eloquent',
        'model' => App\Model\Teacher::class,
    ]
],

2、关于 dingo 中间件不支持多用户

我是这么处理的，在用 dingo 的 api.auth 之前 加上自己写的用于切换 guard 的中间件 如下：

添加中间件
<?php

namespace App\Http\Middleware;

use Closure;

class ChangeAuthGuard
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */

    public function handle($request, Closure $next, $guard)
    {
        app()->singleton('auth.driver', function ($app) use($guard) {
            return $app['auth']->guard($guard);
        });

        return $next($request);
    }
}

注册中间件
App\Http\Kernel
protected $routeMiddleware = [
        'guard' => Middleware\ChangeAuthGuard::class,
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
]

路由中使用注册的中间件
$api->group(['middleware' => ['guard:admin','api.auth']],function ($api){
// admin为你在auth配置文件 guards数组中定义的选项

3、JWT 的 token 过期后抛出的异常不是过期异常

关于 tymon/jwt-auth 的 token 过期后抛出的异常不是过期异常的处理：

public function render($request, Exception $exception)
    {
        // detect instance
        if ($exception instanceof UnauthorizedHttpException) {
            // detect previous instance
            if ($exception->getPrevious() instanceof TokenExpiredException) {
                return response()->json(['error' => 'TOKEN_EXPIRED'], $exception->getStatusCode());
            } else if ($exception->getPrevious() instanceof TokenInvalidException) {
                return response()->json(['error' => 'TOKEN_INVALID'], $exception->getStatusCode());
            } else if ($exception->getPrevious() instanceof TokenBlacklistedException) {
                return response()->json(['error' => 'TOKEN_BLACKLISTED'], $exception->getStatusCode());
            } else {
                return response()->json(['error' => "UNAUTHORIZED_REQUEST"], 401);
            }
        }
        return parent::render($request, $exception);
    }

4、角色隔离

• 1、更改相应的 Model 文件：
  App\Models\User

<?php
namespace App\Models;

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

class User extends Authenticatable implements JWTSubject
{
    use Notifiable;

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

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

    /**
     * 获取会储存到 jwt 声明中的标识
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }

    /**
     * 返回包含要添加到 jwt 声明中的自定义键值对数组
     * @return array
     */
    public function getJWTCustomClaims()
    {
        return ['role' => 'user'];
    }
}

App\Models\Admin

<?php

namespace App\Models;

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

class Admin extends Authenticatable implements JWTSubject
{
    use Notifiable;

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

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

    /**
     * 获取会储存到 jwt 声明中的标识
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }

    /**
     * 返回包含要添加到 jwt 声明中的自定义键值对数组
     * @return array
     */
    public function getJWTCustomClaims()
    {
        return ['role' => 'admin'];
    }
}

• 2、创建中间件检测当前 token 对应的是哪个平台 php artisan make:middleware JWTRoleAuth

<?php

namespace App\Http\Middleware;

use Closure;
use Tymon\JWTAuth\Exceptions\JWTException;
use Tymon\JWTAuth\Http\Middleware\BaseMiddleware;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;

class JWTRoleAuth extends BaseMiddleware
{
    /**
     * JWT 检测当前登录的平台
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  null $role
     * @return mixed
     */
    public function handle($request, Closure $next, $role = null)
    {
        try {
            // 解析token角色
            $tokenRole = $this->auth->parseToken()->getClaim('role');
        } catch (JWTException $e) {
            /**
             * token解析失败，说明请求中没有可用的token。
             * 为了可以全局使用（不需要token的请求也可通过），这里让请求继续。
             * 因为这个中间件的责职只是校验token里的角色。
             */
            return $next($request);
        }
        // 判断token角色。
        if ($tokenRole != $role) {
            throw new UnauthorizedHttpException('jwt-auth', 'User role error');
        }
        return $next($request);
    }
}

• 3、在 router/api.php 文件中创建路由信息

# 普通用户登录
Route::group(['prefix' => 'auth'], function () {
    Route::post('login', 'AuthController@login');
    Route::post('logout', 'AuthController@logout');
    Route::post('refresh', 'AuthController@refresh');
    Route::post('me', 'AuthController@me')->name('me')->middleware(['jwt.role:user', 'jwt.auth']);
});

# 后台用户登录
Route::group(['prefix' => 'admin', 'namespace' => 'Admin'], function () {
    Route::post('login', 'LoginController@login');
    Route::post('logout', 'LoginController@logout');
    Route::post('refresh', 'LoginController@refresh');
    Route::post('me', 'LoginController@me')->middleware(['jwt.role:admin', 'jwt.auth'])->name('me');
});
