Laravel6.0 使用 Jwt-auth 实现多用户接口认证

后台管理员认证 (admins 表)

首先创建数据库和表 (admins)，在 routes/api.php 中，写上如下路由并创建对应控制器和方法。

Route::namespace('Api')->group(function () {
    /***
     * 管理员后台接口路由
     */
    Route::prefix('admin')->namespace('Admin')->group(function () {
        Route::post('register', 'AdminController@register');
        Route::post('login', 'AdminController@login');
    });
    Route::prefix('admin')->namespace('Admin')->group(function () {
        Route::get('/', 'HomeController@index'); //后台首页
    });
});

1、安装 jwt-auth

composer require tymon/jwt-auth:dev-develop

2、在 config/app.php 中注册服务提供者

TymonJWTAuthProvidersLaravelServiceProvider::class,

3、生成配置文件

php artisan vendor:publish --provider="TymonJWTAuthProvidersLaravelServiceProvider"

此命令会在 config 目录下生成一个 jwt.php 配置文件

4、生成密钥

php artisan jwt:secret

此命令会在你的 .env 文件中新增一行 JWT_SECRET=secret

5、创建 admins 表迁移文件

php artisan make:migration create_admins_table

添加如下代码：

public function up()
{
    Schema::create('admins', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->string('email')->unique();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

执行迁移：

php artisan migrate

此时查看数据库，对应的 admins 表已生成。

6、创建模型

由于我们这里后台管理员设置的是 admins 表，所以需创建对应模型，执行如下命令：

php artisan make:model Models/Admin

里面添加如下代码：

<?php

namespace AppModels;

use TymonJWTAuthContractsJWTSubject;
use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;

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',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function getJWTIdentifier()
    {
        return $this->getKey();
    }

    public function getJWTCustomClaims()
    {
        return [];
    }
}

7、配置 Auth guard

在 config/auth.php 文件中，添加 guard 和 Providers，代码如下：

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

*************************

'admins' => [
    'driver' => 'eloquent',
    'model' => AppModelsAdmin::class,
]

8、在 AdminController 中添加如下代码：

<?php

namespace AppHttpControllersApiAdmin;

use IlluminateHttpRequest;
use AppHttpControllersController;
use AppModelsAdmin;
use Hash;

class AdminController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth:admins', ['except' => ['register', 'login']]);
    }

    /***
     * 后台管理员注册
     * @param Request $request
     */
    public function register(Request $request)
    {
        $name = $request->name;
        $email = $request->email;
        $password = $request->password;
        $check_password = $request->check_password;

        if (!$name || !$password) {
            return response()->json(['success' => false, 'message' => '用户名、邮箱或密码必填！']);
        }

        $pattern = "/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,})$/";
        if (!preg_match($pattern, $email)) {
            return response()->json(['success' => false, 'message' => '邮箱格式不正确！']);
        }

        if ($check_password != $password) {
            return response()->json(['success' => false, 'message' => '两次密码输入不一致！']);
        }

        $admin = Admin::where('name', $name)->first();
        if ($admin) {
            return response()->json(['success' => false, 'message' => '用户名已被注册！']);
        }

        $password = Hash::make($password);
        $admin = Admin::create([
            'name' => $name,
            'email' => $email,
            'password' => $password
        ]);

        return response()->json(['success' => true, 'message' => '注册成功！', 'admin' => $admin]);
    }

    /***
     * 后台管理员登录
     * @param Request $request
     */
    public function login(Request $request)
    {
        $email = $request->email;
        $password = $request->password;

        if (!$email || !$password) {
            return response()->json(['success' => false, 'message' => '邮箱或密码填写错误！']);
        }

        $admin = Admin::where('email', $email)->first();
        if (!$admin) {
            return response()->json(['success' => false, 'message' => '此邮箱不存在！']);
        }

        if (!Hash::check($password, $admin->password)) {
            return response()->json(['success' => false, 'message' => '密码填写错误！']);
        }

        $credentials = request(['email', 'password']);
        if (!$token = auth('admins')->attempt($credentials)) {
            return response()->json(['error' => 'Unauthorized'], 401);
        }

        return $this->respondWithToken($token);
    }

    /**
     * Log the admin out (Invalidate the token).
     *
     * @return IlluminateHttpJsonResponse
     */
    public function logout()
    {
        auth()->logout();

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

    /**
     * Refresh a token.
     *
     * @return IlluminateHttpJsonResponse
     */
    public function refresh()
    {
        return $this->respondWithToken(auth('admins')->refresh());
    }

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

测试：

先注册一个后台账号，在 postman 中，如图所示：

 

9、使用中间件，修改之前的路由如下：

Route::namespace('Api')->group(function () {
    /***
     * 管理员后台接口路由
     */
    Route::prefix('admin')->namespace('Admin')->group(function () {
        Route::post('register', 'AdminController@register');
        Route::post('login', 'AdminController@login');
    });
    Route::prefix('admin')->namespace('Admin')->middleware('auth:admins')->group(function () {
        Route::get('/', 'HomeController@index'); //后台首页
    });
});

测试：

实现登录，在 postman 中，如图所示：

 

12、获取管理员信息，在后台首页控制器中写入如下代码：

public function index()
{
    return response()->json(auth('admins')->user());
}

 

至此，后台接口认证已完成！

 

商户后台认证 (merchants 表)

这里的商户后台认证其实是重复上面的步骤，只是换了一张表而已，所以自行完成！

 

小程序前端用户认证 (users 表)

1、在 api.php 中添加路由并创建对应控制器和方法，users 表增加字段 openid

 /***
 * 小程序用户认证接口路由
 */
Route::any('/auth', 'MiniController@auth');

2、在 config/auth.php 文件中，修改 guard 里面的 api 那栏，代码如下：

'users' => [
    'driver' => 'jwt',
    'provider' => 'users',
    'hash' => false,
],

3、修改模型 User.php 代码如下：

<?php

namespace App;

use TymonJWTAuthContractsJWTSubject;
use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;

class User extends Authenticatable implements JWTSubject
{
    use Notifiable;

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

    /**
     * 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 [];
    }
}

4、使用中间件，修改之前的路由如下：

/***
 * 小程序用户认证接口路由
 */
Route::any('/auth', 'MiniController@auth');

Route::middleware('auth:users')->group(function () {
    Route::get('/', 'HomeController@index'); //首页接口
});

5、安装 easyWeChat 第三方包

composer require "overtrue/laravel-wechat:~5.0"  #安装包文件
php artisan vendor:publish --provider="OvertrueLaravelWeChatServiceProvider"  #生成配置文件

打开配置文件 wechat.php 里面的小程序配置和支付配置，在 .env 文件中配置支付的相关参数，如下：

WECHAT_MINI_PROGRAM_APPID=*******
WECHAT_MINI_PROGRAM_SECRET=*******

WECHAT_PAYMENT_MCH_ID=*******
WECHAT_PAYMENT_APPID=*******
WECHAT_PAYMENT_KEY=*******

6、在 MiniController 控制器中添加如下代码：

<?php

namespace AppHttpControllersApi;

use IlluminateHttpRequest;
use AppHttpControllersController;
use AppUser;
use JWTAuth;
use EasyWeChat;
use Auth;

class MiniController extends Controller
{
    public function auth(Request $request)
    {
        $app = EasyWeChat::miniProgram();
        $session = $app->auth->session($request->code);
        $openid = $session['openid'];
//        return $openid;
        //用openid查询数据库，是否已经有了，没有就创建。
        $user = User::firstOrCreate(compact('openid'));

        //生成token
        $token = JWTAuth::fromUser($user);
        return response()->json(['token' => 'Bearer ' . $token]);
    }
}

7、创建一个小程序测试项目，在 app.js 中，刷出 code。然后 postman 测试如图：

 

8、最后一步获取小程序用户 id。在首页接口控制器中写入如下代码，用来打印小程序用户的 openid

public function index()
{
    return response()->json(auth('users')->user()->openid);
}
