PHP如何獲取Cookie並實現模擬登入

一、定義cookie儲存路徑

必須使用絕對路徑

$cookie_jar = dirwww.cppcns.comname(__file__)."/pic.cookie";

二、獲取cookie

將cookie存入檔案

$url = "";

$ch = curl_init();

curvwakjkvgnl_setopt($ch, curlopt_url, $url);

curl_setopt($ch, curlopt_header, 0);

curl_setopt($ch, curlopt_returntransfer, true);

curl_setopt($ch, curlopt_cookiejar, $cookie_jar);

$content = curl_execwww.cppcns.com($c程式設計客棧h);

curl_close($ch);

三、模擬瀏覽器獲取驗證碼

該伺服器驗證碼有漏洞，可以自己指定

取出cookie，一起提交給伺服器，讓伺服器以為是瀏覽器開啟登陸頁面

$ch = curl_init();

curl_setopt($ch, curlopt_url, '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

$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, "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、到指定頁面獲取資料

$ch = curl_init();

curl_setopt($ch, curlopt_url, "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);
