  let smtp_server = "smtp.gmail.com";
  let password = "YOUR_GMAIL_APPLICATION_PASSWORD"; //需要生成应用专用密码
  
  let email = Email::builder()
      .to(email_receiver)
      .from(mine_email)
      .subject("subject")
      .html("<h1>Hi there</h1>")
      .text("Message send by lettre Rust")
      .build()
      .unwrap();
  
  let creds = Credentials::new(
      mine_email.to_string(),
      password.to_string(),
  );
  
  // Open connection to Gmail
  let mut mailer = SmtpClient::new_simple(smtp_server)
      .unwrap()
      .credentials(creds)
      .transport();
  
  // Send the email
  let result = mailer.send(email.into());
  
  if result.is_ok() {
      println!("Email sent");
  } else {
      println!("Could not send email: {:?}", result);
  }
  
  print!("{:?}", result);
  mailer.close();
  }
