Question

我开发了一个网络监控工具。它应该检查网站的状态代码，并决定它是向上还是向下。如果响应代码是200，它将保存得很好，它在数据库中保存为up，否则为down。如果状态代码发生变化，则应该发送更多通知，即从上到下或反之，（它使用保存在数据库中的最后一个状态代码检查新的resCode（响应代码））。但如果网站总是在运行，请不要发送通知。但如果网站关闭，请检查警报频率并发送通知。 sendNotification函数对此负责，但由于某种原因并收到通知的垃圾邮件。它只是在不检查警报频率和状态变化的情况下继续发送通知。任何可以查看我的代码的人。 tnx提前。

这实际上是我从数据库中获取status_health，模型，从上到下的地方

<?php

namespace App;
use App\Status;
use App\Notification;

use Illuminate\Database\Eloquent\Model;

class Notification extends Model
{
    protected $fillable = ['id','website_url','email','slack_channel','check_frequency','alert_frequency','speed_frequency','active'];

    public function statuses(){
        return $this->belongsToMany('App\Status')->withPivot('values')->withTimestamps();
    }

    public function status($s_type)
    {
        if (!in_array($s_type, ['speed', 'health'])){
            return false;
        }

        $o_status = Status::where('name', strval($s_type))->first();
        $o_response = $this->statuses()->where('status_id', $o_status->id)
        ->select('values', 'created_at')->orderBy('created_at','DESC')->first();

        if($o_response === null){
            return false;
        }

        return [
            'value' => $o_response->values,
            'timestamp' => $o_response->created_at
        ];
    }

    public function history($s_type)
    {
        if (!in_array($s_type, ['speed', 'health'])){
            return false;
        }

        $o_status = Status::where('name', strval($s_type))->first();
        $o_response = $this->statuses()->where('status_id', $o_status->id)
        ->select('values', 'created_at')->orderBy('created_at','DESC')->get();

        if($o_response === null || $o_response->count() === 0){
            return false;
        }


        $a_ret = [];
        $last = null;

        foreach ($o_response as $o_status) {
            if($last != $o_status->values) {
                $a_ret[] = [
                'value' => $o_status->values,
                'timestamp' => $o_status->created_at
                ];
                $last = $o_status->values;
            }
        }
        return $a_ret;
    }
}

Answer 1

您可以将状态保存到数据库，如果您从上次检查获得的状态与保存到数据库的状态不同，则可以发送通知并更新de数据库中的状态。

使用此方法，只有在状态发生变化时才会发送通知，而不是每次检查状态时都会发送通知。

如果您使用保存在数据库中的最新支票核对function(aa, bb, Overlaps)，您可以进行比较并考虑发送通知。

当您调用将发送新状态的功能时，您可以检查status_code！= status_code。

希望这有效！

Answer 2

经过大量调试后我得到了答案。问题不在于代码本身。来自http请求的响应代码是一个数字例外字符串200,404等，然后它被保存为字符串值为＆＃34; up＆＃34;或＆＃34; down＆＃34;。当我使用比较resCode（响应代码）和status_health [＆＃39;值＆＃39;]（我从数据库获得的值是一个字符串＆＃34; up＆＃34;或＆＃34; down＆＃ 34;。我实际上是在比较字符串和int值。然后我将resCode更改为字符串，我的问题得到修复.sendNotification函数中的代码得到了改进.Tnx适用于所有试图帮助@Robin Dirksen的人。这里是新代码
