Lumen實現用戶註冊登陸認證

Lumen實現用戶註冊登陸認證

前言

Lumen是一個基於Laravel的微框架，號稱是以速度爲生。截用Lumen官網的一段，號稱是比silex和slim還要快。

本文將用Lumen來實現一個完整的用戶註冊、登陸及獲取用戶信息的API。

Lumen官方網站：https://lumen.laravel.com/
Lumen中文網站：http://lumen.laravel-china.org/

安裝

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

數據庫配置

跟全棧框架 Laravel 框架不同的是，全部的 Lumen 框架的配置信息都存儲在 .env 文件中。一旦 Lumen 成功安裝，你須要 配置本地環境,若是沒有在目錄下新建.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 配置遷移數據庫

php artisan make:migration create_users_table --create=users

執行這條命令後，會在項目目錄lumen/database/migrations/ 目錄下生成一個php文件，這個文件主要包括兩個函數，在up()函數中根據你的需求定義數據庫字段。

<?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'); } }

執行命令，建立數據庫

php artisan migrate

數據庫會生成一張users表

建立用戶數據模型

若是你的項目文件夾lumen\app\文件夾下沒有User.php文件，那麼新建一個User.php文件，文件內容以下：

<?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', ]; }

路由定義

定義三個路由，實現用戶登陸，註冊及獲取用戶信息

路由類型	路由路徑	路由控制器
POST	user/register	UserController@register
POST	user/login	UserController@login
GET	user/info	UserController@info

根據上述表的內容，在routes/web.php中定義路由

<?php $app->get( '/', function () use ($app) { return $app->version(); }); //登陸註冊 $app->post( 'user/login', 'UserController@login'); $app->post( 'user/register', 'UserController@register'); $app->get( 'user/info', [ 'middleware' => 'authToken', 'uses' => 'UserController@info' ]);

Controller邏輯

在Lumen\app\Http\Controllers\文件夾下新建用戶控制器UserController.php，實現用戶註冊、登陸和用戶信息獲取功能

<?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"; } //登陸 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 '用戶名或密碼不正確,登陸失敗'; } } else{ return '登陸信息不完整,請輸入用戶名和密碼'; } } //註冊 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 '用戶註冊成功!'; } else{ return '用戶註冊失敗!'; } } else{ return '請輸入完整用戶信息!'; } } //信息 public function info() { return Auth::user(); }

認證服務

必需要經過token驗證才能獲取用戶信息。在Lumen\app\Http\Providers\AuthServiceProvider.php中定義驗證服務。咱們使用header包含token的形式來驗證。修改Lumen\app\Http\Providers\AuthServiceProvider.php文件代碼。

<?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(); } }); }

定義認證中間件

在Lumen\app\Http\Middleware\文件夾下定義認證路由中間件AuthToken.php，就是以前在路由中定義的」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); } } }

啓用配置信息

在lumen\app\bootstrap\app.php中取消註釋

<?php //讓數據庫信息和認證服務修改生效 $app->withFacades(); $app->withEloquent(); //認證中間件 $app->routeMiddleware([ 'authToken' => App\Http\Middleware\AuthToken::class ]); //開啓註冊提供者 $app->register(App\Providers\AppServiceProvider::class); $app->register(App\Providers\AuthServiceProvider::class);

啓動服務，測試

php -S localhost:8000

1.用戶註冊

查看數據庫

2.用戶登陸

登陸後會更新數據庫的api_token

3.獲取用戶信息

錯誤信息：

1.

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

解決辦法，安裝memcached 和php擴展

brew install memcached brew install php56-memcached 啓動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

解決辦法，須要開啓，路徑app/bootstrap/app.php

$app->withEloquent();
