参数＃1（$ mailable）必须是类型的Illuminate \ Contracts \ Contracts \ Mail \ Mailable，字符串给定

Question

我尝试发送带有新创建帖子的电子邮件。但是我遇到了这个错误，但我不明白怎么了？

Illuminate \ Mail \ PendingMail :: send（）：参数＃1（$ mailable）必须是类型Illuminate \ Contracts \ Contracts \ Contracts \ Mail \ Mail \ mail \ crings，fess in/users/users/mattiasandersson/documents/utveckling/utveckling/tester/tester/event_listener/app/app/app/app/app/app/app/app/app/app/app/听众/notifypostCreated.php在第37行

public function handle(PostCreated $event)

{

    $users = User::all();

    foreach($users as $user) {

        Mail::to($user->email)->send('emails.post_created', $event->post);

    }

}

Answer 1

The value in send() should extend mailable
Assuming you have a PostMail class  as shown below
<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class PostMail extends Mailable 
{
    use Queueable, SerializesModels;


    public $post;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($post)
    {
        //
        $this->post=$post;
    }

    /**
     * Build the message.
     *
     * @return $this`enter code here`
     */
    public function build()
    {
        return $this->subject("Mail from posts")->view('mail.Test_mail');
    }
}

然后，在您的手柄方法上，您可以

public function handle()
    {
        $data = User::all();
        $post=$this->post;
       
        
        
        $postdata = new PostMail($post);
        foreach ($data as $key => $value) {
            $input['email'] = $value->email;
            $input['name'] = $value->name;
           
            Mail::to($input['email'])->send($postdata);
        }
    }

注意：邮件:: to（$ input ['email']） - ＆gt; send（$ postData）; $ postdata是邮政运输类型，可扩展可邮寄。
希望这会有所帮助
