php - 使用 curl 登录并移动到另一个页面

Question

我正在尝试使用 CURL 访问网站中的一个页面，但是它需要登录我尝试了登录代码并且成功了

<?php

    $user_agent       = "Mozilla/5.0 (X11; Linux i686; rv:24.0) Gecko/20140319 Firefox/24.0 Iceweasel/24.4.0";
    $curl_crack = curl_init();

    CURL_SETOPT($curl_crack,CURLOPT_URL,"https://www.vininspect.com/en/account/login");
    CURL_SETOPT($curl_crack,CURLOPT_USERAGENT,$user_agent);
    CURL_SETOPT($curl_crack,CURLOPT_PROXY,"183.78.169.60:37899");
    CURL_SETOPT($curl_crack,CURLOPT_PROXYTYPE,CURLPROXY_SOCKS5);
    CURL_SETOPT($curl_crack,CURLOPT_POST,True);
    CURL_SETOPT($curl_crack,CURLOPT_POSTFIELDS,"LoginForm[email]=naceriwalid%40hotmail.com&LoginForm[password]=passwordhere&toploginform[rememberme]=0&yt1=&toploginform[rememberme]=0");
    CURL_SETOPT($curl_crack,CURLOPT_RETURNTRANSFER,True);
    CURL_SETOPT($curl_crack,CURLOPT_FOLLOWLOCATION,True);
    CURL_SETOPT($curl_crack,CURLOPT_COOKIEFILE,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
    CURL_SETOPT($curl_crack,CURLOPT_COOKIEJAR,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
    CURL_SETOPT($curl_crack,CURLOPT_CONNECTTIMEOUT,30);
    CURL_SETOPT($curl_crack,CURLOPT_TIMEOUT,30);  

    $exec = curl_exec($curl_crack);
    if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
    {
        echo "yoooha";
    }

?>

现在我面临的唯一问题是我不想被重定向到登录页面，我想被重定向到此页面 http://example.com/buy , 我怎样才能用相同的代码做到这一点？

如果您想在登录后转到 /buy，只需使用相同的 curl 句柄并为该页面发出另一个请求。 cURL 将在句柄期间保留 cookie(以及后续请求，因为您将它们保存到文件中并使用 cookie jar 读回它们。

例如:

$user_agent       = "Mozilla/5.0 (X11; Linux i686; rv:24.0) Gecko/20140319 Firefox/24.0 Iceweasel/24.4.0";
$curl_crack = curl_init();

CURL_SETOPT($curl_crack,CURLOPT_URL,"https://www.vininspect.com/en/account/login");
CURL_SETOPT($curl_crack,CURLOPT_USERAGENT,$user_agent);
CURL_SETOPT($curl_crack,CURLOPT_PROXY,"183.78.169.60:37899");
CURL_SETOPT($curl_crack,CURLOPT_PROXYTYPE,CURLPROXY_SOCKS5);
CURL_SETOPT($curl_crack,CURLOPT_POST,True);
CURL_SETOPT($curl_crack,CURLOPT_POSTFIELDS,"LoginForm[email]=naceriwalid%40hotmail.com&LoginForm[password]=passwordhere&toploginform[rememberme]=0&yt1=&toploginform[rememberme]=0");
CURL_SETOPT($curl_crack,CURLOPT_RETURNTRANSFER,True);
CURL_SETOPT($curl_crack,CURLOPT_FOLLOWLOCATION,True);
CURL_SETOPT($curl_crack,CURLOPT_COOKIEFILE,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
CURL_SETOPT($curl_crack,CURLOPT_COOKIEJAR,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
CURL_SETOPT($curl_crack,CURLOPT_CONNECTTIMEOUT,30);
CURL_SETOPT($curl_crack,CURLOPT_TIMEOUT,30);  

$exec = curl_exec($curl_crack);
if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
{
    $post = array('search' => 'keyword', 'abc' => 'xyz');

    curl_setopt($curl_crack, CURLOPT_POST, 1); // change back to GET
    curl_setopt($curl_crack, CURLOPT_POSTFIELDS, http_build_query($post)); // set post data
    curl_setopt($curl_crack, CURLOPT_URL, 'http://example.com/buy'); // set url for next request

    $exec = curl_exec($curl_crack); // make request to buy on the same handle with the current login session
}
