php 模拟登陆（不带验证码）采集数据

这里模拟表单登陆窗口

提交代码部分

1，生成session_id保存到 cookie

$login_url = '/Login.php';

$cookie_file = dirname(__FILE__)."/pic.cookie";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $login_url);

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);

curl_exec($ch);

curl_close($ch);

2,处理提交的登陆的数据

if($_POST['acti']=='tj'){

$userid=$_POST['userid'];

$password=$_POST['password'];

$_post_url = '/login.php?action=Login';//登录表单提交地址

$post = "userid=$userid&password=$password";

$ch12 = curl_init();

curl_setopt($ch12, CURLOPT_URL, $_post_url);

curl_setopt($ch12, CURLOPT_HEADER, false);

curl_setopt($ch12, CURLOPT_RETURNTRANSFER,1);

curl_setopt($ch12, CURLOPT_POSTFIELDS, $post); //提交方式为post

curl_setopt($ch12, CURLOPT_COOKIEFILE, $cookie_file);

curl_exec($ch12);

curl_close($ch12);

//以上表示登陆成功

//以下开始采集数据

$data_url19 = "/xxxxxxx.php?id=10";//数据所在地址

$ch19 = curl_init();

curl_setopt($ch19, CURLOPT_URL, $data_url19);

curl_setopt($ch19, CURLOPT_HEADER, false);

curl_setopt($ch19, CURLOPT_HEADER, 0);

curl_setopt($ch19, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch19, CURLOPT_COOKIEFILE, $cookie_file);

$content12 = curl_exec($ch19);

file_put_contents("./content0/31-35/net" . $k . ".txt", $content12); //文件存放的位置

}
