Php 如何在laravel中发送带有附件（pdf）的电子邮件？

我想发送一封带有附件（pdf）的电子邮件，该附件来自一个请求。没有附件。一封电子邮件发送得很完美，但带有附件，它抛出了一个错误

    Fatal error: Uncaught exception 'Swift_IoException' with message 'The path cannot be empty' 

这是我的邮件课

class MyMail extends Mailable {
use Queueable, SerializesModels;
public $details;

public function __construct($details =[]) {
    $this->details = $details;
}

public function build() {
    if ($this->details['file']) {
        return $this->subject('New applicant')
            ->from("my@email.com", "name")
            ->view('email.mail')
            ->attach($this->details['file']->getRealPath(), 
                [
                    'as'   => $this->details['file']->getClientOriginalName(),
                    'mime' => $this->details['file']->getClientMimeType(), 
                ]);
    }

}

}

这是我的控制器代码

        $file = $request->file('file ');
        if ($file) {
            $file_name = hexdec(uniqid());
            $ext       = strtolower($file->getClientOriginalExtension());

            $file_full_name = $file_name . '.' . $ext;
            $upload_path    = 'files/';
            $upload_path1   = 'backend/files/';
            $file_url       = $upload_path . $file_full_name;
            $success        = $file->move($upload_path1, $file_full_name);
        }
        $details = [
            'applicant_name'    => $request->name,
            'applicant_contact' => $request->contact,
            'applicant_email'   => $request->email,
            'file'              => $file,
        ];

        $base_email = 'example@email.com';
        Mail::to($base_email)->send(new MyMail($details));

有人能帮助我如何发送带有附件的电子邮件吗？

您是根据请求直接附加的。但您应该将图像上载到存储或公用文件夹。然后您可以附加图像路径

$details = [
            'applicant_name'    => $request->name,
            'applicant_contact' => $request->contact,
            'applicant_email'   => $request->email,
            'file'              => $file,
            'fileUrl' => $file_url,
        ];

 $this->subject('New applicant')
            ->from("my@email.com", "name")
            ->view('email.mail')
            ->attach(asset( $this->details['fileUrl']), 
                [
                    'as'   => $this->details['file']->getClientOriginalName(),
                    'mime' => $this->details['file']->getClientMimeType(), 
                ]);

参考：

在我的控制器中，我上传了文件并将其发送到邮件类，如下所示：

    if ($request->has('resume')) {
        $file = $request->file('resume');
        $file_name =  Str::random(7) . '.'.$file->getClientOriginalExtension();
        $destinationPath = "/followUp";
        $file->move(public_path($destinationPath), $file_name);
        $file = 'followUp/'.$file_name;
    }
    $subject = 'پیگیری رزومه - ایندید';

    Mail::to('visanewcom@gmail.com')->send(new sendMail($username,$mobile,$subject,$file));

然后在send mail类中：

 return $this->view('email.followUp')

    ->with('username',$this->username)
        ->with('mobile',$this->mobile)
        ->with('file',$this->file)
        ->subject($this->subject)
        ->attach(public_path($this->file), [
            'as' => 'resume.pdf',
            'mime' => 'application/pdf',
        ])
        ;

在从请求附加之前，我将文件存储到我的公用文件夹中。再次看到帖子，我补充道code@ihprince. updatedtry从存储中而不是从请求中获取文件
