php curl模拟答题,总是400错误

Jun 23, 2016 pm 02:24 PM

php curl php curl

我想模拟这个网站的答题:http://zsjs.kaiwind.com/kf/html/index.html
他是在上面的页面登陆,之后到新的页面去答题,答题全部结束且真确之后,允许提交。
他是ajax提交,全部js验证通过后,回想后台发送ajax请求,完成页面。

他发送的数据倒是不复杂,但是在模拟他数据发送的时候,却总是出错,下面贴出代码和错误提示,望各位大神给予解救。
代码:
curl请求部分:
<?phpfunction vget($url,$header = null){//模拟获取内容函数  	global $browsers;     $curl = curl_init();//启动一个CURL会话        curl_setopt($curl, CURLOPT_URL, $url);//要访问的地址                	curl_setopt($curl, CURLOPT_HTTPHEADER, $browsers);//设置HTTP头	    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);// 对认证证书来源的检查      curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1);// 从证书中检查SSL加密算法是否存在        curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);// 模拟用户使用的浏览器	curl_setopt($curl,CURLOPT_REFERER,'HTTP://www.baidu.com');        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);// 使用自动跳转        curl_setopt($curl, CURLOPT_AUTOREFERER, 1);// 自动设置Referer        curl_setopt($curl, CURLOPT_HTTPGET, 1);// 发送一个常规的GET请求	curl_setopt($curl, CURLOPT_COOKIEJAR, $GLOBALS['cookie_file']);//保存cookie文件	if(isset($header) && !is_null($header)){		curl_setopt($curl, CURLOPT_HTTPHEADER, $header);//设置头信息的地方  	}	curl_setopt($curl, CURLOPT_HEADER, true);    curl_setopt($curl, CURLOPT_TIMEOUT, 30);// 设置超时限制防止死循环        curl_setopt($curl, CURLOPT_HEADER, 0);// 显示返回的Header区域内容        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);// 获取的信息以文件流的形式返回        $tmpInfo = curl_exec($curl);// 执行操作        if (curl_errno($curl)){       echo 'Errno'.curl_error($curl);    }    curl_close($curl);// 关闭CURL会话    return $tmpInfo;// 返回数据    }function vpost($url,$data){ // 模拟提交数据函数 	global $browsers;	//$header = "Content-type: application/x-www-form-urlencoded";//定义content-type为xml       $curl = curl_init(); // 启动一个CURL会话        curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址                    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查  	curl_setopt($curl, CURLOPT_HTTPHEADER, $browsers);//设置HTTP头	    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); // 从证书中检查SSL加密算法是否存在        curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转    	curl_setopt($curl, CURLOPT_REFERER, 'http://zsjs.kaiwind.com/kf/html/question.html?15238132836?10');    //curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer        curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求        curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包        curl_setopt($curl, CURLOPT_COOKIEFILE, $GLOBALS['cookie_file']); // 读取上面所储存的Cookie信息        curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环        curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回        $tmpInfo = curl_exec($curl); // 执行操作        if (curl_errno($curl)){           echo 'Errno'.curl_error($curl);        }    curl_close($curl); // 关键CURL会话        return $tmpInfo; // 返回数据    }
Copy after login

执行部分:
<?php	header('Content-type:text/html;charset=utf-8');	$phone = '15238132836';	$area  = '10';	$cookie_jar = tempnam('./','cookie');//指定保存sessionid的cookie文件位置		$data = array(			'tel'=>urlencode($phone),			'area'=>urlencode($area)	);		$GLOBALS['cookie_file'] = $cookie_jar;	require_once('./functions.php');	$url = 'http://zsjs.kaiwind.com/kf/html/index.html';	// vget($url);	//exit();	$browsers = array (        "Accept" => "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",        "Accept-Encoding" => "gzip, deflate",		"Accept-Language"=>"zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3",		"Cache-Control"=>"max-age=0",		"Connection"=>"keep-alive",		"Content-type"=>"application/x-www-form-urlencoded",		//"Cookie"=>"CNZZDATA199524=cnzz_eid%3D713570903-1381646309-http%253A%252F%252Fzsjs.kaiwind.com%26ntime%3D1381738758%26cnzz_a%3D0%26retime%3D1381738758499%26sin%3D%26ltime%3D1381738758499%26rtime%3D1",		"Host"=>"zsjs.kaiwind.com",		"User-Agent"=>"Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0"        );		$url = 'http://zsjs.kaiwind.com/kf/kfcheck.php';	dump(vpost($url,$data));	exit();	$url = 'http://zsjs.kaiwind.com/kf/kfsub.php';	dump(vpost($url,$data));?>
Copy after login


页面返回的结果:

cookie放在最后一行、?

curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
