PHP Redis 限制API和各种接口 请求频率

PHP Redis 限制API和各种接口 请求频率

来保证接口的安全

<?php 

require('predis/src/Autoloader.php');
$redis = new Predis\Client(array(
	'scheme' => 'tcp',
	'host'   => '127.0.0.1',
	'port'   => '6379'
));
$redis->auth('123456');

//这个key记录该用户1的访问次数 
$key = 'user:1:api_count';

//限制次数为10 
$limit = 10;

$check = $redis->exists($key);
if($check){
	$redis->incr($key);
	$count = $redis->get($key);
	if($count > 10){
		exit('your have too many request');
	}
}else{
	$redis->incr($key);
	//限制时间为60秒 
	$redis->expire($key,60);
}

$count = $redis->get($key);
echo 'You have '.$count.' request';

//API业务逻辑 
echo '<br/>';
echo 'Hello,World!This is the api content.';
