Laravel 5.8 做个知乎 15 —— 站内信通知

1 创建通知表

php artisan notifications:table

php artisan migrate

2 代码

2.1 appNotificationsNewUserFollowNotinfication.php

php artisan make:notification NewUserFollowNotinfication

use IlluminateSupportFacadesAuth;

    public function via($notifiable)
    {
        //        return ['mail'];   //邮件通知
        return ['database']; //站内信
    }
    
    public function toDatabase($notifiable)
    {
        return [
          'name'=> Auth::guard('api')->user()->name,
        
        ];
    }

2.2 appHttpControllersApiFollowersController.php

use AppNotificationsNewUserFollowNotinfication;

    public function follow()
    {
        $userToFollow = $this->user->byId(request('user'));
        
        $followed = Auth::guard('api')->user()->followThisUser($userToFollow->id);
        
        if (count($followed['attached']) > 0 ){
            $userToFollow->increment('followers_count');
            $userToFollow->notify(new NewUserFollowNotinfication());
            return response()->json(['followed'=>true]);
        }
        $userToFollow->decrement('followers_count');
        return response()->json(['followed'=>false]);
    }

notifications表里就会有新增一行
