为了实现注册机才写的教程，为了批量注册一个网站，注册带有验证码，幸好是文本验证码，但是有session验证，于是POST必须携带cookie。代码如下。
<?php
class AutoCurl{
private $curl;
private $strCookie;
public $url;
public $data;
function __construct(){
$this->curl=curl_init();
$this->strCookie='tmp.cookie';
if(!file_exists('tmp.cookie')){
$ckfile = fopen("tmp.cookie", "w") or die("Unable to open file!");
fclose($ckfile);
}
}
function __destruct(){
curl_close($this->curl);
}
function CurlGet(){
curl_setopt($this->curl, CURLOPT_URL, $this->url);
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true) ;
curl_setopt($this->curl, CURLOPT_BINARYTRANSFER, true) ;
//important
curl_setopt($this->curl,CURLOPT_CONNECTTIMEOUT, 5);
//save_cookie
curl_setopt($this->curl,CURLOPT_COOKIEJAR,$this->strCookie);
$output = curl_exec($this->curl) ;
return $output;
}
function CurlPost(){
curl_setopt($this->curl,CURLOPT_POST,1);
//send_cookie
curl_setopt($this->curl,CURLOPT_COOKIEFILE, $this->strCookie);
curl_setopt($this->curl,CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->curl,CURLOPT_URL,$this->url);
curl_setopt($this->curl,CURLOPT_POSTFIELDS,$this->data);
$output = curl_exec($this->curl) ;
return $output;
}
}
//实例化一个会话
$newcurl= new AutoCurl();
//第一步GET获取Cookie和验证码
//设置登录填充的Url
$newcurl->url='http://www.jinghong.in/index.php?m=user&mod=reg';
//发送Get
$result=$newcurl->CurlGet();
//获取验证码
if(preg_match('/\<b\>(.*)\<\/b\>/U',$result, $matches)){
$code=$matches[1];
}
//第二步POST提交注册
//设置登录提交的Url
$newcurl->url='http://www.jinghong.in/index.php?m=user&mod=reg&act=ok';
//设置发送POST数据
$newcurl->data=array("name" =>'a'.rand(pow(10,(6-1)), pow(10,6)-1),"sj" => "1".rand(pow(10,(11-1)), pow(10,11)-1),"email" =>rand(pow(10,(5-1)), pow(10,5)-1)."@qq.com","pass" => rand(pow(10,(7-1)), pow(10,7)-1)."qqcom","bzyzm" => $code);
//发送Post
$result=$newcurl->CurlPost();
var_dump($result);
?>
