Laravel 9 SymfonyMailer 错误 - 电子邮件必须包含 "To"、"Cc" 或 "Bcc" header

Question

将使用 Metronic 8 主题的 Laravel 8 项目更新到 Laravel 9 后，发送电子邮件时遇到问题。我没有更改任何与电子邮件相关的代码，但现在我在使用 Sendmail driver :

时遇到了这个错误

An email must have a "To", "Cc", or "Bcc" header. {"userId":6,"exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "To", "Cc", or "Bcc" header. at /home/myhome/public_html/myproject.com/vendor/symfony/mime/Message.php:128)

控制器

class MyController extends Controller
{
    public function activate($id)
    {
        $mymodel = MyModel::find($id);

        $contact = Contact::where('mymodel_id', $mymodel->id)->first();
        Mail::to($contact->email)->send(new MyMail($contact));
    }
}

可邮寄

class MailActive extends Mailable
{
    use Queueable, SerializesModels;

    protected $contact;

    public function __construct(Contact $contact)
    {
        $this->contact = $contact;
    }

    public function build()
    {
        return $this->from('theemail@gmail.com', 'Me')
            ->view('emails.myemailview')
            ->with([
                'contact' => $this->contact
            ]);

        // $this->withSymfonyMessage(function (Email $message) {
        //     $message->getHeaders()->addTextHeader(
        //         'addAddress', 'theemail@gmail.com'
        //     );
        // });

        // return $this;
    }
}

我试过单独渲染邮件，效果很好。使用日志 driver，它有效，正如你所见，我什至尝试使用可邮寄 class 中的 withSymfonyMessage 方法绕过 Mail facade，但没有任何效果。

是否有我缺少的配置或部分？我可以回去使用 SwiftMailer 而不用担心 Laravel 9 工作吗？

Answer 1

使用->to()

return $this->from('theemail@gmail.com', 'Me')
            ->to($email, $name)
            ->view('emails.myemailview')
            ->with([
                'contact' => $this->contact
            ]);

Answer 2

An email must have a "To", "Cc", or "Bcc" header. {"userId":6,"exception":"[object] (Symfony\Component\Mime\Exception\LogicException(code: 0): An email must have a "To", "Cc", or "Bcc" header. at /home/myhome/public_html/myproject.com/vendor/symfony/mime/Message.php:128)

如果缺少 to() 或者如果 to() 方法在您的 Mailable class

中收到一个空集合，您将得到上述异常
