Rate Limit

Requirement :

1. Redis Installed with no forcing password authentication
2. Redis for PHP (Extension) Installed

Add code below to each PHP file before the original PHP code :

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);


$max_calls_limit  = 30;
$time_period      = 30;
$total_user_calls = 0;

if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $user_ip_address = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $user_ip_address = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $user_ip_address = $_SERVER['REMOTE_ADDR'];
}

if (!$redis->exists($user_ip_address)) {
    $redis->set($user_ip_address, 1);
    $redis->expire($user_ip_address, $time_period);
    $total_user_calls = 1;
} else {
    $redis->INCR($user_ip_address);
    $total_user_calls = $redis->get($user_ip_address);
    if ($total_user_calls > $max_calls_limit) {
   
            $json = array("Status"=>"Fail","Message"=>"Rate limit exceeded!","IP Address"=>$user_ip_address,"Total_Calls"=>$total_user_calls,"Period"=>$time_period);
       header('Content-type: application/json');  header('Access-Control-Allow-Origin: *');
     header('HTTP/1.1 429 Too Many Requests');
   echo (json_encode($json));
        exit();
    }
}

Place these code BEFORE the original PHP code Example :

<?php
[PLACE HERE THE RATE LIMIT CODE!]
$date_request = $_GET["date"];
if (empty($date_request)) {
   $json = array("Status"=>"Fail","Message"=>"Did not provide query string - date. Please refer to https://covid-19.samsam123.name.my/api.html for more information.");
    header('Content-type: application/json');  header('Access-Control-Allow-Origin: *');
   echo (json_encode($json)); ..........
?>

Final :

<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);


$max_calls_limit  = 30;
$time_period      = 30;
$total_user_calls = 0;

if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $user_ip_address = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $user_ip_address = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $user_ip_address = $_SERVER['REMOTE_ADDR'];
}

if (!$redis->exists($user_ip_address)) {
    $redis->set($user_ip_address, 1);
    $redis->expire($user_ip_address, $time_period);
    $total_user_calls = 1;
} else {
    $redis->INCR($user_ip_address);
    $total_user_calls = $redis->get($user_ip_address);
    if ($total_user_calls > $max_calls_limit) {
   
            $json = array("Status"=>"Fail","Message"=>"Rate limit exceeded!","IP Address"=>$user_ip_address,"Total_Calls"=>$total_user_calls,"Period"=>$time_period);
       header('Content-type: application/json');  header('Access-Control-Allow-Origin: *');
     header('HTTP/1.1 429 Too Many Requests');
   echo (json_encode($json));
        exit();
    }
}
$date_request = $_GET["date"];
if (empty($date_request)) {
   $json = array("Status"=>"Fail","Message"=>"Did not provide query string - date. Please refer to https://covid-19.samsam123.name.my/api.html for more information.");
    header('Content-type: application/json');  header('Access-Control-Allow-Origin: *');
   echo (json_encode($json)); ..........
?>

The rate limit code is same as the rate limit section on API section
Any IP Address that exceed 30 requests in 30 seconds will receive a 429 Too Many Requests and a JSON string contains IP Address and Total Call Requests in 30 seconds.
The rate limit will be auto reset each 30 seconds.
