Laravel Queue未将变量发送到刀片文件

如何解决Laravel Queue未将变量发送到刀片文件

我正在尝试使用mailables和Laravel Queue发送大量电子邮件。我将主题和消息作为变量传递。当我不使用队列时，没有任何问题可以完美地发送电子邮件，但是在关闭http连接（即关闭浏览器）时，此操作会中断。

使用队列时出现问题，该变量未传递到刀片模板。

控制器

public function newsletter(Request $request)
    {
        $job = (new SendNewsLetter($request->all()))->delay(Carbon::now()->addSeconds(5));
        dispatch($job);

        Session::flash('message','Email Sent');
        Session::flash('class','success');
        return redirect()->route('news');
    }

工作

    public $tries = 1; 

    public $request;

    public function __construct($request)
    {
        //
        $this->request = $request;
        $request = $this->request;
    }

    public function handle(Request $request)
    {
        $data = array(
            'message' => $request->message,'subject' => $request->subject,'file' => $request->file("file")
        );
        //dd($data);
        $teachingLevel = $request->highest_teaching_level;
        $school = $request->school;
        $province = $request->province;
        $district = $request->district;

        $subject = $request->subject;

        if ($teachingLevel != "" && $school != "" && $province != "" && $district != "") {
            $email = User::where('highest_teaching_level',$teachingLevel)->where('current_school_name',$school)->where('address','LIKE','%'.$province.'%')->where('address','%'.$district.'%')->pluck('email');
        }else{
        $email = User::pluck('email');
        }
        
        foreach($email as $e)
        {
            Mail::to($e)->send(new NewsLetter($data,$subject));
        }
    }

邮件

    public $data;
    public $subject;

    public function __construct($data,$subject)
    {
        //
        $this->subject = $subject;
        $this->data = $data;
    }

    public function build()
    {
        $name = 'test';
        //dd($name);
        if ($this->data['file'] != "") {
            # code...
            return $this->subject($this->subject)->markdown('mail.newsletter')->with('data',$this->data)->attach($this->data['file']->getRealPath(),[
                'as' => $this->data['file']->getClientOriginalName()
            ]);
        }else{
            //dd($this->subject);
            return $this->subject($name)->markdown('mail.newsletter')->with('data',$this->data);
        }

    }

我查看了这样的多个答案-> here

但是不起作用，变量没有传递到刀片模板是因为变量存储方式存在问题。

我的替代方案是先将消息存储在DB中，然后从那里检索数据

解决方法

请使您的__construct函数和handle函数如下所示。

public function __construct($request)
{
    //
    $this->request = $request;
    
}

public function handle()
{
    $request = $this->request;
    //to see what you're getting \Log::info([$request]);
    //rest of the logic.
}

,

首先，在使用类的属性时应使用“ this”。

public function __construct($request)
{
    //
    $this->request = $request;
    $request = $this->request; REMOVE IT
}
///
    $data = array(
        'message' => $this->request->message,'subject' => $this->request->subject,'file' => $this->request->file("file")
    );

第二，添加更改后，您很有可能忘记执行命令。

php artisan queue:restart
