让HTTP代理更加智能化

一、HTTP代理的应用环境

刷票、发帖、刷流量等需要在短时间内换大量IP的应用

二、在使用HTTP代理的难点

1.选出能有且速度快的代理较难

2.用选出的代理在实际使用中会出现不稳定情况,需要针对此IP进行智能化的再鉴定和剔除工作

3.伪造初始IP地址,如果只是简单的应用代理,服务器很简单的就能检测出原始IP

三、程序的书写

[php]
public function get(url) { this->curl = curl_init();
if(this->proxy){ curl_setopt (this->curl, CURLOPT_PROXY,this->proxy); curl_setopt (this->curl, CURLOPT_HTTPHEADER, array(‘CLIENT-IP:’.this->client_ip, ‘X-FORWARDED-FOR:’.this->client_ip));
echo this->proxy; } curl_setopt(this->curl, CURLOPT_URL, url); curl_setopt(this->curl, CURLOPT_HEADER, 1);
curl_setopt(this->curl, CURLOPT_USERAGENT, “Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)”); curl_setopt(this->curl, CURLOPT_COOKIE, this->cookie); curl_setopt(this->curl, CURLOPT_RETURNTRANSFER, 1);
data = curl_exec(this->curl);
curl_close(this->curl); preg_match_all(“/Set-Cookie:(.*?);/”, data, match, PREG_SET_ORDER); foreach (match as r) { if (this->cookie != ”) {
this->cookie = this->cookie . ‘;’;
}
if (isset(r[1])) { this->cookie .= trim(str_replace("rn", "", r[1])); } } this->set(this->cookie_name,this->cookie);
return $data;

}
[/php]
