我已经写了一个自动化脚本发送OTP电子邮件。我已经存储在一个字符串列表的电子邮件。下面是代码：

public static void main(String[] args) throws FileNotFoundException, Exception{
        
        EmailUtils emailUtils = new EmailUtils();
        
        Properties prop = new Properties();
        prop.load(new FileInputStream("/Users//Automation/Automation/src/main/java/Resources/config-email-otp.properties"));
        Store connection = emailUtils.connectToGmail(prop);
        emailUtils.getUnreadMessages(connection, "Inbox");
        
        List<String> emailtext = emailUtils.getUnreadMessageByFromEmail(connection, "Inbox", "no-reply@xxxx.in", "Email ID verification");

现在，我想从电子邮件中提取OTP。
通过电子邮件发送它在控制台中的显示方式：

This is the message envelope
---------------------------
FROM: dummyemail@gmail.com
TO: dummyemail@gmail.com
SUBJECT: Email ID verification 
----------------------------
CONTENT-TYPE: TEXT/HTML; charset=us-ascii
This is a string
---------------------------
<!doctype html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.t.org">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Email verification</title>
</head>
<body>
<div>Dear User,</div>

<div>You are performing account verification operation , the verification code is:  <b>4740</b></div>

<div>This verification code can only be used once, and it will automatically become invalid after verification.</div>

<div>(Please complete the verification within 30 minutes, the verification code will become invalid after 30 minutes, you need to verify again.)</div>

<div>Please ignore this email if we send the wrong address, thanks.</div>

String emailText = "Your email text"; 
        String pattern = "code is:  <b>(\d{4}+)";

        // Create a Pattern object
        Pattern r = Pattern.compile(pattern);

        // Now create matcher object.
        Matcher m = r.matcher(line);

        if (m.find()) {
            System.out.println("Found value: " + m.group(0));
            System.out.println("Found value: " + m.group(1));
            System.out.println("Found value: " + m.group(2));
        } else {
            System.out.println("NO MATCH");
        }
    }

您需要群组1的值。如果只使用\d{4}，您也会符合w3.org的年份。x1c 0d1x
