基于PHP给大家讲解防刷票的一些技巧,php讲解技巧

刷票行为,一直以来都是个难题,无法从根本上防止。

但是我们可以尽量减少刷票的伤害,比如:通过人为增加的逻辑限制。

基于 PHP,下面介绍防刷票的一些技巧:

1、使用CURL进行信息伪造

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8'));
curl_setopt($ch, CURLOPT_REFERER, "http://localhost/ ");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.0)");
$out = curl_exec($ch);
curl_close($ch);

2、验证码:采用非常复杂的验证码

确切的说验证码的出现不是针对于人,而是针对于机器。通过复杂度和识别难易度的控制来阻拦掉一部分刷票机,从而减少刷票的发生。但随着软件技术、识别技术的发展越来越多的验证码面对着先进的刷票软件也失去了其防范的作用、但是专业刷票机可以攻破。如果不用验证码,投票基本就歇菜了,验证码获取方式,采用异步加载,即点击输入框时,才去请求,投票成功后,删除验证码的 Session

3、限时投票

比如:从早8点至晚23 点

4、设置投票间隔

用户投票后,需要隔多长时间才能继续投。

很多投票站点基本上都有这个限制,但是对于更改 IP的攻击,就没办法了

5、投票结果展示:延迟展示,友好展示

页面上投票,JS 立马加1,但是刷新页面,不一定立马展示最新投票结果,返回状态给页面(感谢您的投票!或者 投票成功!至于有没有成功,另说了!)

6、扣量逻辑:常见于一些软件评选之类的投票

这是个杀手锏,后台跑脚本实时监控异常增长(刷票)的项,然后实施扣量逻辑
即对于这个项,投 10 票才算一票

7、Cookie:常用的手段。比较低级

投票后,在客户端写入 Cookie,下次投票时判断 Cookie 是否存在
但是,这种方式非常容易攻破,因为 Cookie 可删除

8、加密选项 ID:对一些投票选项的ID,进行随机加密

加密算法,加Salt,并且设置有效时间,比如5分钟内
服务器端进行解密并且验证

9、nginx限制链接数

ngx_http_limit_conn_module
ngx_http_limit_req_module
nginx_limit_speed_module

可以使用这三个模块来限制,不过这不是一个好的解决方法

10、iptables限制

/sbin/iptables -A INPUT -p tcp --dport 80 --syn -m recent --name webpool --rcheck --seconds 60 --hitcount 10 -j DROP
/sbin/iptables -A INPUT -p tcp --dport 80 --syn -m recent --name webpool --set -j ACCEPT
/sbin/iptables -t filter -A INPUT -p tcp --dport 80 --tcp-flags FIN,SYN,RST,ACK SYN -m connlimit --connlimit-above 10 --connlimit-mask
 32 -j REJECT

具体脚本

#!/bin/bash
# Date: 2015-09-29
# # Author: cpz@erongtu.com
shopt -s -o nounset
export PATH=/usr/bin/:/bin
iptables_log="/tmp/iptables_conf.log"
/sbin/iptables -A INPUT -p tcp --dport 80 --syn -m recent --name webpool --rcheck --seconds 60 --hitcount 10 -j DROP
/sbin/iptables -A INPUT -p tcp --dport 80 --syn -m recent --name webpool --set -j ACCEPT
/sbin/iptables -t filter -A INPUT -p tcp --dport 80 --tcp-flags FIN,SYN,RST,ACK SYN -m connlimit --connlimit-above 10 --connlimit-mask 32 -j REJECT
while [ true ]; do
  #sleep 1
  for IP in `netstat -an | grep -i ':80 '|grep 'ESTAB' | awk '{print $5}' | cut -d : -f 1 | sort | uniq -c | awk '{if($1 > 30 && $2!="127.0.0.1" ) {print $2}}'`
  do
    /sbin/iptables -L -n | grep $IP >/dev/null || /sbin/iptables -A INPUT -p tcp --dport 80 -s $IP -j DROP
    echo "/sbin/iptables -A INPUT -p tcp -s $IP -j DROP" >> ${iptables_log}
  done
done
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
