PHP curl 抓包问题

Jun 23, 2016 pm 01:45 PM

用curl抓取网页书据，成绩，课表都是用这种方法抓取的，但是抓取就不行了，报500错误

这是用httpwatch抓包工具抓取的页面，cookie正确拿到

这是要抓取的界面，数据通过post传输

<html>	<head>		<meta charset=gbk>	</head>	<body>		<form action="" method="post">		学号：<input type="text" name="user">		<br>		密码：<input type="password" name="password">		<br>		<input type="submit" name="login" value="登录">		</form>	</body><?php	if(isset($_POST["login"])) {	$login = $_POST["user"];	$password = $_POST["password"];	$url = "http://202.117.64.25/loginAction.do";	$fields = "dllx=dldl&zjh=201224080126&mm=201224080126";	$cookie1 = "D:\wamp\www\cookielogin.txt";	$cookie2 = "D:\wamp\www\cookie.txt";	$ch = curl_init();	curl_setopt($ch, CURLOPT_URL, $url);	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)");	curl_setopt($ch, CURLOPT_POST, 1);	curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);	curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie1);	curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);	$result = curl_exec($ch);	curl_close($ch);	$url = "http://202.117.64.25/xszxcxAction.do?oper=tjcx";	$fields = "zxxnxq=2014-2015-1-1&zxXaq=0&zxJxl=0011&zxZc=1&zxJc=1%2C2&zxxq=1&pageSize=20&page=1&currentPage=1&pageNo=1";	$ch = curl_init();	curl_setopt($ch, CURLOPT_URL, $url);	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)");	curl_setopt($ch, CURLOPT_POST, 1);	curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);	curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie1);	curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);	$result = curl_exec($ch);	echo $result;}?></html>

报错界面

回复讨论(解决方案)

第一：带上CURLOPT_REFERER试试，对方是不是有可能判断了页面来源
第二：对方的登陆页是否有隐藏参数，如果有的话需要先访问登陆页获取隐藏值再提交
第三：没看见你什么地方提交了登录的账号和密码，就是自己这边POST过来的账号和密码

$url = "http://202.117.64.25/loginAction.do";
$fields = "dllx=dldl&zjh=201224080126&mm=201224080126";
这是提交账户和密码！
CURLOPT_REFERER 要加什么？

找到两个隐藏参数，但是貌似没什么用

帮你测试了一下，登录是没问题的，已经登录成功，主要问题出在你第二次请求的参数上，检查一下参数，抓取你第二个页面上所有的参数下来，另外JAVA的这个报错不是很懂！

你抓取成功了吗？

大家帮忙看看，怎么回事？？？

你的流程和代码都有问题！正确的流程应该是：
1、访问 http://202.117.64.25/
获取 cookie。因为他的 sessionid 在这个页面发出的
2、访问 http://202.117.64.25/loginAction.do 并发送 post 表单数据
3、第2步返回的是一个框架页，你得根据需要进入某个框架
比如访问 http://202.117.64.25/menu/s_top.jsp 可以得到已登录信息：欢迎光临黄小龙

非常感谢你，成功了，但是还是不知道为什么？
这是我最终代码

<?phpinclude './curl/curl_get.php';$url = "http://202.117.64.25/loginAction.do";$d = 'dllx=dldl&zjh=201224080126&mm=201224080126';curl_get($url, $d);echo curl_get('http://202.117.64.25/xszxcxAction.do?oper=tjcx', 'zxxnxq=2014-2015-1-1&zxXaq=0&zxJxl=0011&zxZc=11&zxJc=2&zxxq=2&pageSize=20&page=1&currentPage=1&pageNo=');?>
