一、下载 laravel 5.3

composer create-project laravel/laravel=5.3.* laravel5.3_notifyDatabase

新建数据库 laravel5.3_notifyDatabase

修改 .evn 配置文件

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel5.3_notifyDatabase
DB_USERNAME=laravel5.3_notifyDatabase
DB_PASSWORD=laravel5.3_notifyDatabase

修改中国时区，在 config/app.php 中修改

'timezone' => 'PRC',

二、创建数据

切换目录

cd laravle5.3_notifyDatabase

创建 post model

php artisan make:model Post -m

生成 notifications table

php artisan notifications:table

修改迁移文件：posts_table.php

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->string('content');
        $table->timestamps();
    });
}

修改 database/factories/ModelFactory.php

$factory->define(App\Post::class, function (Faker\Generator $faker) {
    return [
        'title' => $faker->sentence,
        'content' => $faker->paragraph,
    ];
});

执行数据迁移

php artisan migrate

创建用户数据

php artisan tinker
factory('App\User', 5)->create();

创建文章数据

factory('App\Post', 5)->create();

三、notification

创建 PostPublished notification

php artisan make:notification PostPublished

修改 app/Notifications/PostPublished.php

public $post;

public function __construct(\App\Post $post)
{
    $this->post = $post;
}

public function via($notifiable)
{
    return ['database'];
}

public function toArray($notifiable)
{
    return $this->post->toArray();
}

注意：这里也可以新增 toDatabase($notifiable) 方法，如果有该方法就会执行该方法，没有的话就执行 toArray($notifiable)

修改 routes/web.php

Auth::loginUsingId(1);

Route::get('/', function () {
    $post = \App\Post::find(1);
    Auth::user()->notify(new \App\Notifications\PostPublished($post));
});

启动 serve

php artisan serve

访问 http://localhost:8000 进行测试

打开 tinker

php artisan tinker

查看发送的通知

Auth::user()->notifications

可以看到 data 就是刚刚 toArray($notifiable) 返回的数据

四、展示消息

修改 routes/web.php

Auth::loginUsingId(1);

Route::get('/', function () {
    return view('welcome');
});

Route::delete('user/notification', function (){
    Auth::user()->unreadNotifications->markAsRead();
    return redirect()->back();
});

修改视图文件：resources/views/welcome.blade.php

新建视图文件：resources/views/notifications/post_published.blade.php

访问 http://localhost:8000 进行测试

点击标记已读

再次在 tinker 中查看数据

Auth::user()->fresh()->notifications

发现 read_at 字段已记录
