PHP如何获取Cookie并实现模拟登录

一、定义Cookie存储路径

必须使用绝对路径

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

二、获取Cookie

将cookie存入文件

?

1 2 3 4 5 6 7 8

$url = "http://1.2.3.4/" ; $ch = curl_init(); curl_setopt( $ch , CURLOPT_URL, $url ); curl_setopt( $ch , CURLOPT_HEADER, 0); curl_setopt( $ch , CURLOPT_RETURNTRANSFER, true); curl_setopt( $ch , CURLOPT_COOKIEJAR, $cookie_jar ); $content = curl_exec( $ch ); curl_close( $ch );

三、模拟浏览器获取验证码

该服务器验证码有漏洞，可以自己指定

取出cookie，一起提交给服务器，让服务器以为是浏览器打开登陆页面

?

1 2 3 4 5 6 7

$ch = curl_init(); curl_setopt( $ch , CURLOPT_URL, 'http://1.2.3.4/getCheckpic.action?rand=6836.185874812305' ); curl_setopt( $ch , CURLOPT_COOKIEFILE, $cookie_jar ); curl_setopt( $ch , CURLOPT_HEADER, 0); curl_setopt( $ch , CURLOPT_RETURNTRANSFER, 1); $ret = curl_exec( $ch ); curl_close( $ch );

四、POST提交

?

1 2 3 4 5 6 7 8 9

$post = "name=2&userType=1&passwd=asdf&loginType=1&rand=6836&imageField.x=25&imageField.y=7" ;  $ch = curl_init(); curl_setopt( $ch , CURLOPT_URL, "http://1.2.3.4/loginstudent.action" ); curl_setopt( $ch , CURLOPT_HEADER, false); curl_setopt( $ch , CURLOPT_RETURNTRANSFER,1); curl_setopt( $ch , CURLOPT_POSTFIELDS, $post ); curl_setopt( $ch , CURLOPT_COOKIEFILE, $cookie_jar ); $result =curl_exec( $ch ); curl_close( $ch );

五、到指定页面获取数据

?

1 2 3 4 5 6 7 8 9

$ch = curl_init(); curl_setopt( $ch , CURLOPT_URL, "http://1.2.3.4/accountcardUser.action" ); curl_setopt( $ch , CURLOPT_HEADER, false); curl_setopt( $ch , CURLOPT_HEADER, 0); curl_setopt( $ch , CURLOPT_RETURNTRANSFER,0);    curl_setopt( $ch , CURLOPT_COOKIEFILE, $cookie_jar ); $html =curl_exec( $ch ); // var_dump($html); curl_close( $ch );
