Question

在我的数据库中，我有通知表，其中包含要检查的URL并检查频率列和警报频率列。我现在尝试做的是代码。发送http请求后，代码应该能够执行以下操作。

检查网站是否已启动以及状态是否已更改，然后发送通知。否则什么都不做。
如果网站已关闭且状态已更改，则发送通知。
如果网站已关闭且状态未发生变化，请检查警报频率。如果elapse_time大于警报频率，则发送通知。

这就是我想要实现但未能做到的事情。我的代码需要一些改进。

<?php
namespace App\Http\Controllers;
use GuzzleHttp\Client;
use App\Utilities\Reporter;
use GuzzleHttp\Exception\ClientException;
use App\Notification;
use App\Status;
use App\Setting;
use Carbon;
class GuzzleController extends Controller
{
    private $default_check_frequency;

    protected $client;

    protected $reporter;

    public function __construct()
    {
        $this->client = new Client();

        $this->reporter = new Reporter;

        $this->default_check_frequency = Setting::defaultCheckFrequency();

        $this->default_alert_frequency = Setting::defaultAlertFrequency();
    }

    private function addStatusToNotification(Notification $notification, Status $status, $resCode)
    {
        $notification->statuses()->attach($status, [
            'values' => $resCode === 200
                ? 'up'
                : 'down'
        ]);
    }

    private function report(Notification $notification, $resCode)
    {
        /* how to send slack to different slach channels, now it is sending only to one channel!*/

        $this->reporter->slack($notification->website_url . ':' . '  is down' . ' this is the status code!' . ' @- ' .$resCode,
                               $notification->slack_channel);

        $this->reporter->mail($notification->email,$notification->website_url.' is down '. ' this is the status Code: '. $resCode);
    }

    private function sendNotification(Notification $notification, Status $status, $status_health, $frequency, $resCode)
    {
        $elapsed_time = \Carbon\Carbon::parse($status_health['timestamp'])->diffInMinutes();

        if ($elapsed_time >= $frequency) {
            $this->addStatusToNotification($notification, $status, $resCode);

            if ($resCode != 200) {
                $this->report($notification, $resCode);
            }
        }
    }

    public function status()
    {
        $notifications = Notification::where('active', 1)->get();

        $status = Status::where('name', 'health')->first();

        foreach ($notifications as $notification) {
            $this->updateStatus($notification, $status);
        }
    }

    private function updateStatus(Notification $notification, Status $status)
    {
        $resCode = $this->getStatusCode($notification->website_url);

        $this->sendNotification(
            $notification,
            $status,
            $notification->status('health'),
            $this->getFrequency($notification, $resCode),
            $resCode
        );
    }

    private function getFrequency(Notification $notification, $resCode)
    {

        switch ( $resCode) {
          case '200':
            return isset($notification->check_frequency)
            ? intval($notification->check_frequency)
            : $this->default_check_frequency;
            break;

          default:
            return isset($notification->alert_frequency)
            ? intval($notification->alert_frequency)
            : $this->default_alert_frequency;
            break;
        }
    }

    private function getStatusCode($url)
    {
        try {
            $response = $this->client->get($url, [
                'http_errors' => false
            ]);

            return $response->getStatusCode();

        } catch (\GuzzleHttp\Exception\ConnectException $e) {

        }
    }
}

如果网站关闭或状态发生变化，则发出警报
