curl模拟请求、登陆以及带验证码登陆

header('content-type:text/html;charset=utf-8');
function curlPost($url,$data,$method){
$ch = curl_init();   //1.初始化
curl_setopt($ch, CURLOPT_URL, $url); //2.请求地址
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);//3.请求方式
//4.参数如下
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);//https
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');//模拟浏览器
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip, deflate'));//gzip解压内容
curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');

if($method=="POST"){//5.post方式的时候添加数据
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$tmpInfo = curl_exec($ch);//6.执行

if (curl_errno($ch)) {//7.如果出错
return curl_error($ch);
}
curl_close($ch);//8.关闭
return $tmpInfo;
}
$data=array('name' => '1234');
$url="http://www.sohu.com/";

$method="GET";  //post或者get
$file=curlPost($url,$data,$method);
$file=mb_convert_encoding($file,'UTF-8','GBK');
echo $file;

以下是模拟登陆的代码

<?php
$cookie_file = tempnam('./temp','cookie');
function weixinPost($url,$data,$method,$setcooke=false,$cookie_file=false){
$ch = curl_init();   //1.初始化
curl_setopt($ch, CURLOPT_URL, $url); //2.请求地址
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);//3.请求方式
//4.参数如下
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

if($method=="POST"){//5.post方式的时候添加数据
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
if($setcooke==true){
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
}else{
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$tmpInfo = curl_exec($ch);//6.执行

if (curl_errno($ch)) {//7.如果出错
return curl_error($ch);
}
curl_close($ch);//8.关闭
return $tmpInfo;
}
$data=array('username' => '***','password'=>'***');
$url="http://www.xinxinj.com/login.php";
$method="POST";
$file=weixinPost($url,$data,$method,true,$cookie_file);
echo $file;

$url="http://www.xinxinj.com/admin.php";
$method="GET";
$file=weixinPost($url,$data,$method,false,$cookie_file);
echo $file;

网上的很多模拟登录程序，大都是通过服务程序apache之类的运行，获取到验证码之后显示在网页上，然后填上再POST出去

 

本文提供了一个程序实例，思路就是获取到验证码之后把验证码存储为一个图片，然后程序休眠20秒，在20秒之后由用户手动查看图片，并把验证码填写到code.txt文件中，20秒休眠完成后，程序会读code.txt的验证码，这样再带着验证码进行登录操作。具体代码如下：

/**
* 模拟登录
*/

//初始化变量
$cookie_file = "tmp.cookie";
$login_url = "http://xxx.com/logon.php";
$verify_code_url = "http://xxx.com/verifyCode.php";

echo "正在获取COOKIE...\n";
$curlj = curl_init();
$timeout = 5;
curl_setopt($curl, CURLOPT_URL, $login_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($curl,CURLOPT_COOKIEJAR,$cookie_file); //获取COOKIE并存储
$contents = curl_exec($curl);
curl_close($curl);

echo "COOKIE获取完成，正在取验证码...\n";
//取出验证码
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $verify_code_url);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$img = curl_exec($curl);
curl_close($curl);

$fp = fopen("verifyCode.jpg","w");
fwrite($fp,$img);
fclose($fp);
echo "验证码取出完成，正在休眠，20秒内请把验证码填入code.txt并保存\n";
//停止运行20秒
sleep(20);

echo "休眠完成，开始取验证码...\n";
$code = file_get_contents("code.txt");
echo "验证码成功取出：$code\n";
echo "正在准备模拟登录...\n";

$post = "username=maben&pwd=hahahaha&verifycode=$code";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
$result=curl_exec($curl);
curl_close($curl);

//这一块根据自己抓包获取到的网站上的数据来做判断
if(substr_count($result,"登录成功")){
echo "登录成功\n";
}else{
echo "登录失败\n";
exit;
}

//OK，开始做你想做的事吧。。。。。
