在HTML表单中发送API-key

Question

因此，我有一个用于我的Key服务的API密钥。每次用户注册时，我都会给他发送一封电子邮件，让他验证自己的帐户。这看起来像这样：

public class EmailSender {

private static final String username = "somesecretemail@gmail.com";
private static final String password = "uthoughiwillshowyoumypassword?";

public static void sendVerificationCode(String receiverusername, String receiveremail, String code) throws Exception {
    Properties prop = new Properties();
    prop.put("mail.smtp.host", "smtp.gmail.com");
    prop.put("mail.smtp.port", "587");
    prop.put("mail.smtp.auth", "true");
    prop.put("mail.smtp.starttls.enable", "true"); //TLS

    Session session = Session.getInstance(prop,
            new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    });

    MimeMessage message = new MimeMessage(session);
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(receiveremail));
    message.setSubject("Verification Code");

    MimeBodyPart messageBodyPart = new MimeBodyPart();
    messageBodyPart.setText("<form action=\"https://pathtomywebserviceurl.com/verify/"+code+"\">\n" +
    "<input type=\"submit\" value=\"Verify\" />\n" +
     "</form>", "UTF-8", "html");

    Multipart multipart = new MimeMultipart();
    multipart.addBodyPart(messageBodyPart);

    message.setContent(multipart);

    Transport.send(message);
}

当他点击按钮时，用户实际上向我的webservice发出了一个请求，并将他的令牌作为参数。但现在我也希望我的API-Key被发送为eg。一个http头，这样我就可以从用户验证请求中提取API-Key，并检查API-Key是否等于实际的API-Key。现在我只发送代码，而不发送API-Key。

使用隐藏的表单元素：

<input type="hidden" id="myApiKey" name="myApiKey" value="myApiKeyValue">
