php curl模拟答题,总是400错误
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 }
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));?>
页面返回的结果:

回复讨论(解决方案)
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
把这句注释掉试试

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
