Title: Analysis of the impact of Discuz canceling verification codes and solutions

With the increasing development of the Internet, spam and malicious attacks are becoming increasingly rampant. In order to protect the website For security and user experience, many websites use verification codes and other means to identify users. However, some websites decide to cancel the verification code because they find the verification code to be cumbersome. What will be the impact of this approach? This article will analyze it from two aspects: impact and solutions. At the same time, specific code examples are also given to help website managers better manage their websites.

Impact:

1. Reduced security: Cancellation of verification code verification makes you vulnerable to malicious attacks and web crawler intrusions, leading to security issues such as website information leakage and user account theft.
2. Increase in spam: Canceling the verification code will cause registration robots to register users in batches, maliciously publish advertisements and other spam, affecting the quality of website content and user experience.
3. Decreased user experience: Canceling verification code verification will increase the complexity of user login and registration, reduce users’ desire and convenience to use the website, and directly affect the website’s activity and retention rate.

Solution:

1. Strengthen other security measures: After canceling the verification code verification, you can strengthen other security measures such as IP banning, data encryption, user behavior analysis, etc. to improve the website security.
2. Add manual review: After canceling the verification code, you can add a manual review mechanism and let the administrator manually review user registration information and published content to avoid the proliferation of malicious information.
3. Add verification methods: In addition to verification code verification, you can add mobile phone number verification, email verification and other methods to improve the reliability of user identification.

The following is a code example for strengthening the IP ban when Discuz cancels the verification code:

// 取消验证码时加强IP封禁
// 在Discuz的后台管理中设置需要封禁的IP列表，自动将恶意IP列入黑名单

$ban_ips = array("127.0.0.1", "192.168.1.1"); // 设置需要封禁的IP列表

$ip = $_SERVER['REMOTE_ADDR']; // 获取用户访问IP

if(in_array($ip, $ban_ips)){
    // 如果用户IP在黑名单中，则拒绝访问
    header('HTTP/1.1 403 Forbidden');
    die("Forbidden");
}

Through the above method, combined with other security measures and verification methods, you can cancel the verification code verification Under the premise, it can effectively improve the security and user experience of the website, allowing website administrators to better maintain and manage their websites. I hope the analysis and code examples in this article will be helpful to the majority of website managers.
