PHPMailer 不会发送带有不在上传文件夹中的附件的电子邮件(仅在生产中)

PHPMailer won't send an email with attachment which is not already in the uploads folder(Only in production)

我正在我的网站上制作联系我们表格,我使用 PHPMailer 处理将表格发送到我的电子邮件,在我的本地主机和我使用的免费在线主机 (Heroku) 上一切正常用于测试网站。公司发布网站时出现问题,当我们附加上传文件夹中不存在的文件(或与上传文件夹中的文件名称不同)时,表单不会提交。

有没有人遇到过这个问题,是代码问题还是服务器问题还是什么?

这是我的代码:

  $path = 'upload/' . $_FILES["personalCV"]["name"];
  move_uploaded_file($_FILES["personalCV"]["tmp_name"], $path);   
  use PHPMailer\PHPMailer\PHPMailer;
  use PHPMailer\PHPMailer\Exception;
  $mail = new PHPMailer(true);

  try {
    //Server settings
      // $mail->SMTPDebug = 2;                                       // Enable verbose debug output
      $mail->isSMTP();                                            // Set mailer to use SMTP
      $mail->Host       = 'smtp.gmail.com';  // Specify main and backup SMTP servers
      $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
      $mail->Username   =// <SMTP username>
      $mail->Password   =// <SMTP password>
      $mail->SMTPSecure = 'ssl';                                  // Enable TLS encryption, `ssl` also accepted
      $mail->Port       = 465;
      //Recipients
      $mail->setFrom(<email>, <AS Website>);
      $mail->addAddress(<address>, <name>);
      $mail->addAddress(<address>, <name>);     // Add a recipient
      // Attachments
      $mail->AddAttachment($path);

      // Content
      $mail->isHTML(true);                                  // Set email format to HTML
      $mail->Subject = 'New Job Application From The AS Website ( '.$position.' )';
      $msg = '<p> Name : '.$firstName.' '.$lastName.'</p>
              <p>Email Address: '.$email.'
              </p> <p>Phone Number: '.$phoneNum.'</p>
              <p>Position Appling For: '.$position.'</p>
              <p> Message: '.$message.'</p>';
      $mail->Body    = $msg;
      $mail->send();
      $successMsg = '<div class="alert alert-success" role="alert">
                      Message successfully sent
                     </div>';
  } catch (Exception $e) {
    $failMsg = '<div class="alert alert-danger" role="alert">
    Message not successfully sent, please try again
    </div>';
    }
  }

问题已解决,是服务器配置的问题。
