laravel之用户认证(无限用户认证)

版本5.3
太基础的不讲解，讲一些见解

快速生成auth

php artisan migrate
php artisan make:auth

生成文件

路由配置
routes/web.php

Auth::routes()
也可以写成
App::make('router')->auth();

上面的路由，其实对应如下路由

 $this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
        $this->post('login', 'Auth\LoginController@login');
        $this->post('logout', 'Auth\LoginController@logout')->name('logout');

        // Registration Routes...
        $this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
        $this->post('register', 'Auth\RegisterController@register');

        // Password Reset Routes...
        $this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
        $this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
        $this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
        $this->post('password/reset', 'Auth\ResetPasswordController@reset');

看下注册

  $this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

对应控制器

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

看到这个

 use RegistersUsers;

说明用了trait定义类，实现快速认证，减少自己写轮子
vendor/laravel/framework/src/Illuminate/Foundation/Auth/RegistersUsers.php

注册页面

    public function showRegistrationForm()
    {
        return view('auth.register');
    }

如果你自己需要更改页面，则在控制器重写这个方法即可

注册提交页面

public function register(Request $request)
    {
      //验证规则
        $this->validator($request->all())->validate();
        //启动事件,并且注册调用create的create方法来写入数据
        event(new Registered($user = $this->create($request->all())));
        //使用哪个guard(认证器)这个就是决定你用什么表，一会说
        $this->guard()->login($user);
        //判断registered是否写了返回，如果有则使用，如果没有，则调用redirectPath这个方法，这个方法里面还判断了很多，如果你的控制器写了protected $redirectTo = '/home';这个属性，则使用这个来实现注册成功跳转
        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
    }

好了这个注册认证就那么简单，这个时候，比如我现在有个需求
我分3端来认证怎么办，3端分表为:
用户注册，商家注册，管理员注册

这个时候就用了多认证，首先来配置下config/auth.php

<?php

return [
    /*默认用户认证既是Auth::guard()*/
    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        //商家的认证驱动
        'providers' => [
            'driver' => 'session',
            'provider' => 'providers',
        ],
       //后台管理员认证驱动
         'admin' => [
            'driver' => 'session',
            'provider' => 'admin',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
    ],
     //对应上面的provider
    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],
        //假设商家的模型叫Provider
        'providers' => [
            'driver' => 'eloquent',
            'model' => App\Provider::class,
        ],
        'admin' => [
            'driver' => 'eloquent',
            'model' => App\admin::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

    'passwords' => [
        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],
    ],

];

配置好上面，假设我现在要增加一个商家注册呢
创建迁移表，

php artisan make:migration create_table_providers --create=providers

把用户的表结构复制到providers迁移表里面这里，为了方便，就复制一样的了

php artisan migrate

创建类

php artisan make:model Provider

Provider.php

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Provider extends Authenticatable
{
    use Notifiable;
    //
    protected $fillable = [
        'name', 'email', 'password',
    ];

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

创建中间件

php artisan make:middleware ProviderMiddleware

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class ProviderMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
      *$guard='providers'定义这个为默认驱动
     */
   public function handle($request, Closure $next,$guard='providers')
    {
        if (Auth::guard($guard)->guest()) {
            if ($request->ajax() || $request->wantsJson()) {
                return response('Unauthorized.', 401);
            } else {
                return redirect()->guest('provider/auth/regist');
            }
        }

        return $next($request);
    }
}

首先是注册路由

Route::group(['prefix'=>'provider'],function(){
    Route::group(['prefix'=>'auth','namespace'=>'ProvidersAuth'],function(){
        Route::get('/regist','RegistController@showRegistrationForm');
        Route::post('/regist','RegistController@register');
    });

    Route::get('/', ['middleware'=>'providers','uses'=>'HomeController@provider']);
});

然后复制自动生成的注册页面内容到目录ProviderAuth下
并重写一些方法

<?php

namespace App\Http\Controllers\ProvidersAuth;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use App\Provider;
use Auth;

class RegistController extends Controller
{
    //
    use RegistersUsers;
    protected $redirectTo = '/provider/';
    protected $guard='providers';
    public function __construct()
    {
        $this->middleware('guest');
    }
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }
    public function showRegistrationForm(){
        return view('providerauth.register');
    }

    protected function create(array $data)
    {
        return Provider::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
    //这里是关键拉，表示我使用providers，如果不重写，则默认使用了user
    protected function guard()
    {
        return Auth::guard($this->guard);
    }
}

复制auth下视图到providerauth，然后更改里面的路径地址，即可
这个时候浏览器打开

http://192.168.132.200:82/provider/

因为没有登录，经过中间件之后，调转到regist

注册一个看看

这个时候就完成了商户的注册了，很简单吧，只需要复制改下其他的，就可以完成了。登录操作也是差不多。
