Laravel中如何检查通知是否发送成功？

因为Notification::send()方法返回值是void，没法直接通过返回值调用success()方法判断状态，你可以通过以下几种方式实现需求：

方法一：捕获发送过程中的异常 #

Laravel在通知发送失败时（比如邮件配置错误、第三方通道调用失败等）会抛出异常，通过try-catch块捕获这些异常来判断发送状态：

public function AskForLevelUp()
{
    try {
        $admin = User::where('is_admin', 1)->first();
        Notification::send($admin, new LevelUpNotification(Auth::user()->id));
        
        return back()->with('success', 'Your request has been submitted, please wait for admin confirmation.');
    } catch (\Exception $e) {
        // 可在此记录错误日志，方便后续排查问题
        \Log::error('Level up notification failed: ' . $e->getMessage());
        
        return back()->with('failure', 'Something went wrong, your request is not submitted. Please try again later.');
    }
}

方法二：检查数据库通知记录（如果使用数据库通道） #

如果你的通知配置了数据库存储通道（默认的database通道），可以在发送后查询数据库，确认是否生成了对应的通知记录：

public function AskForLevelUp()
{
    $admin = User::where('is_admin', 1)->first();
    $userId = Auth::user()->id;
    
    Notification::send($admin, new LevelUpNotification($userId));
    
    // 检查admin是否收到了这条目标通知
    $notificationExists = $admin->notifications()
        ->where('type', LevelUpNotification::class)
        ->where('data->user_id', $userId) // 假设通知的data字段中包含user_id
        ->exists();
        
    if ($notificationExists) {
        return back()->with('success', 'Your request has been submitted, please wait for admin confirmation.');
    } else {
        return back()->with('failure', 'Something went wrong, your request is not submitted. Please try again later.');
    }
}

方法三：自定义通道的发送状态追踪 #

如果你使用的是自定义通知通道（比如短信、第三方推送），可以在通知类的对应发送方法里捕获发送结果，比如在toMail()或自定义的ToXXX()方法中记录状态：

// LevelUpNotification.php
class LevelUpNotification extends Notification
{
    public $sendSuccess = false;
    
    public function __construct(public $userId) {}
    
    public function via($notifiable)
    {
        return ['mail']; // 假设使用邮件通道
    }
    
    public function toMail($notifiable)
    {
        try {
            $message = (new MailMessage)
                ->line('User ' . $this->userId . ' is requesting level up.');
                
            $this->sendSuccess = true;
            return $message;
        } catch (\Exception $e) {
            $this->sendSuccess = false;
            throw $e; // 继续抛出异常让外层捕获，或自行处理
        }
    }
}

然后在控制器中调用：

public function AskForLevelUp()
{
    try {
        $admin = User::where('is_admin', 1)->first();
        $notification = new LevelUpNotification(Auth::user()->id);
        
        Notification::send($admin, $notification);
        
        if ($notification->sendSuccess) {
            return back()->with('success', 'Your request has been submitted, please wait for admin confirmation.');
        } else {
            return back()->with('failure', 'Something went wrong, your request is not submitted. Please try again later.');
        }
    } catch (\Exception $e) {
        \Log::error('Notification failed: ' . $e->getMessage());
        return back()->with('failure', 'Something went wrong, your request is not submitted. Please try again later.');
    }
}
