How PHP connects with Tencent Cloud Green Website Protection Service to implement malicious attack interception function

With the rapid development of the Internet, network security issues have become increasingly prominent. Malicious attacks target the security vulnerabilities of the website, posing a great threat to the normal operation of the website and the security of user information. In order to improve website security, Tencent Cloud provides green website protection services to protect website security by intercepting malicious attacks in real time.

This article will introduce how to use PHP to connect to Tencent Cloud Green Website Protection Service to implement the malicious attack interception function. We will use the API interface provided by Tencent Cloud for docking.

First, we need to create a green website protection instance on the Tencent Cloud console and obtain the API key and API key ID of the instance. Then, we can write PHP code and call the API interface provided by Tencent Cloud to intercept malicious attacks to intercept attacks.

The following is a sample code:

 'BanIp',
    'ip' => '127.0.0.1', // 需要拦截的IP地址
    'expire' => 3600, // 拦截时间（单位为秒）
);

// 生成签名
$stringToSign = http_build_query($params);
$signature = base64_encode(hash_hmac('sha1', $stringToSign, $secretKey));

// 发送请求
$url = 'https://wss.api.qcloud.com/v2/index.php';
$params['SecretId'] = $secretKeyId;
$params['Timestamp'] = time();
$params['Nonce'] = mt_rand(1, 999999);
$params['Signature'] = $signature;

// 发起POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析响应结果
$result = json_decode($response, true);
if ($result['code'] === 0) {
    echo '恶意攻击已拦截';
} else {
    echo '拦截失败，错误信息：'.$result['message'];
}
?>

In the above code, we first configured the API key and API key ID related to Tencent Cloud Green Website Protection. Then, the IP addresses that need to be intercepted and the interception time are defined. Next, we call Tencent Cloud's malicious attack interception API interface by generating a signature and sending a POST request. Finally, the response results are parsed and processed based on the results.

Using the above code, we can implement malicious attack interception function in PHP. When a malicious attack is detected, we can intercept it by calling Tencent Cloud's API interface to protect website security.

It should be noted that since sensitive information such as API keys are involved, it is recommended to place this part of the code in a secure environment and replace the API keys regularly to improve security.

To sum up, by connecting PHP to Tencent Cloud Green Website Protection Service, we can implement the interception function of malicious attacks and protect the security of the website. Hope this article is helpful to you.
