Lumen实现用户注册登录认证

前言

Lumen是一个基于Laravel的微框架，号称是以速度为生。截用Lumen官网的一段，号称是比silex和slim还要快。

本文将用Lumen来实现一个完整的用户注册、登录及获取用户信息的API。

Lumen官方网站：https://lumen.laravel.com/
Lumen中文网站：http://lumen.laravel-china.org/

安装

composer create-project --prefer-dist laravel/lumen lumen

数据库配置

跟全栈框架 Laravel 框架不一样的是，所有的 Lumen 框架的配置信息都存储在 .env 文件中。一旦 Lumen 成功安装，你需要 配置本地环境,如果没有在目录下新建.env文件

APP_ENV=local APP_DEBUG=true APP_KEY=SomeRandomString!!! DB_CONNECTION=mysql DB_HOST=localhost DB_PORT=3306 DB_DATABASE=lumen DB_USERNAME=root DB_PASSWORD=charlie CACHE_DRIVER=memcached QUEUE_DRIVER=sync APP_TIMEZONE=PRC DB_TIMEZONE=+08:00

三 配置迁移数据库

php artisan make:migration create_users_table --create=users

执行这条命令后，会在项目目录lumen/database/migrations/ 目录下生成一个php文件，这个文件主要包括两个函数，在up()函数中根据你的需求定义数据库字段。

<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateUsersTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create(‘users‘, function (Blueprint $table) { $table->increments(‘id‘); $table->string(‘username‘); $table->string(‘password‘); $table->string(‘email‘); $table->string(‘api_token‘, 60)->unique(); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists(‘users‘); } }

执行命令，创建数据库

php artisan migrate

数据库会生成一张users表

创建用户数据模型

如果你的项目文件夹lumen\app\文件夹下没有User.php文件，那么新建一个User.php文件，文件内容如下：

<?php namespace App; use Illuminate\Auth\Authenticatable; use Laravel\Lumen\Auth\Authorizable; use Illuminate\Database\Eloquent\Model; use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract; use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract; class User extends Model implements AuthenticatableContract, AuthorizableContract { use Authenticatable, Authorizable; /** * The attributes that are mass assignable. * * @var array */ protected $fillable = [ ‘username‘, ‘email‘, ‘password‘, ‘api_token‘ ]; /** * The attributes excluded from the model‘s JSON form. * * @var array */ protected $hidden = [ ‘password‘, ]; }

路由定义

定义三个路由，实现用户登录，注册及获取用户信息

路由类型	路由路径	路由控制器
POST	user/register	[email protected]
POST	user/login	[email protected]
GET	user/info	[email protected]

根据上述表的内容，在routes/web.php中定义路由

<?php $app->get(‘/‘, function () use ($app) { return $app->version(); }); //登录注册 $app->post(‘user/login‘, ‘[email protected]‘); $app->post(‘user/register‘, ‘[email protected]‘); $app->get(‘user/info‘, [ ‘middleware‘ => ‘authToken‘, ‘uses‘ => ‘[email protected]‘ ]);

Controller逻辑

在Lumen\app\Http\Controllers\文件夹下新建用户控制器UserController.php，实现用户注册、登录和用户信息获取功能

<?php namespace App\Http\Controllers; use App\User; use App\Http\Controllers\Controller; use Illuminate\Http\Request; use Illuminate\Support\Facades\Auth; class UserController extends Controller { private $salt; public function __construct() { $this->salt = "userloginregister"; } //登录 public function login(Request $request) { if($request->has(‘username‘) && $request->has(‘password‘)){ $user = User::where(‘username‘, ‘=‘, $request->input(‘username‘))->where(‘password‘, ‘=‘, sha1($this->salt.$request->input(‘password‘)))->first(); if($user){ $token = str_random(60); $user->api_token = $token; $user->save(); return $user->api_token; }else{ return ‘用户名或密码不正确,登录失败‘; } }else{ return ‘登录信息不完整,请输入用户名和密码‘; } } //注册 public function register(Request $request) { if($request->has(‘username‘) && $request->has(‘password‘) && $request->has(‘email‘)){ $user = new User; $user->username = $request->input(‘username‘); $user->password = sha1($this->salt.$request->input(‘password‘)); $user->email = $request->input(‘email‘); $user->api_token = str_random(60); if($user->save()){ return ‘用户注册成功!‘; }else{ return ‘用户注册失败!‘; } }else{ return ‘请输入完整用户信息!‘; } } //信息 public function info() { return Auth::user(); }

认证服务

必须要通过token验证才能获取用户信息。在Lumen\app\Http\Providers\AuthServiceProvider.php中定义验证服务。我们使用header包含token的形式来验证。修改Lumen\app\Http\Providers\AuthServiceProvider.php文件代码。

<?php namespace App\Providers; use App\User; use Illuminate\Support\Facades\Gate; use Illuminate\Support\ServiceProvider; class AuthServiceProvider extends ServiceProvider { /** * Register any application services. * * @return void */ public function register() { // } /** * Boot the authentication services for the application. * * @return void */ public function boot() { // Here you may define how you wish users to be authenticated for your Lumen // application. The callback which receives the incoming request instance // should return either a User instance or null. You‘re free to obtain // the User instance via an API token or any other method necessary. $this->app[‘auth‘]->viaRequest(‘api‘, function ($request) { if ($request->header(‘api_token‘)) { return User::where(‘api_token‘, ‘=‘, $request->header(‘api_token‘))->first(); } }); }

定义认证中间件

在Lumen\app\Http\Middleware\文件夹下定义认证路由中间件AuthToken.php，就是之前在路由中定义的”authToken”。

<?php namespace App\Http\Middleware; use Closure; use Illuminate\Support\Facades\Auth; class AuthToken { public function handle($request, Closure $next) { if(Auth::check()){ return $next($request); }else{ abort(401); } } }

启用配置信息

在lumen\app\bootstrap\app.php中取消注释

<?php //让数据库信息和认证服务修改生效 $app->withFacades(); $app->withEloquent(); //认证中间件 $app->routeMiddleware([ ‘authToken‘ => App\Http\Middleware\AuthToken::class ]); //开启注册提供者 $app->register(App\Providers\AppServiceProvider::class); $app->register(App\Providers\AuthServiceProvider::class);

启动服务，测试

php -S localhost:8000

1.用户注册

查看数据库

2.用户登录

登录后会更新数据库的api_token

3.获取用户信息

错误信息：

1.

[Symfony\Component\Debug\Exception\FatalErrorException] Class ‘Memcached‘ not found

解决办法，安装memcached 和php扩展

brew install memcached brew install php56-memcached 启动memcached memcached -D

2.

PHP Fatal error: Call to a member function connection() on null in /Users/03315/www/lumen/vendor/illuminate/database/Eloquent/Model.php on line 1013

解决办法，需要开启，路径app/bootstrap/app.php

$app->withEloquent();
