Question

我正在尝试使用已保存的Cookie，而不是每次访问网站时都登录。

<?php
$uid = $_GET['uid'];
$ch = curl_init();
$cookie_file = dirname(__FILE__) . '/cookie.txt';
curl_setopt($ch, CURLOPT_URL, "http://www.forum.net/member.php?action=do_login");
curl_setopt($ch, CURLOPT_REFERER, "http://www.forum.net/member.php?action=login");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.56 Safari/536.5");
curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . '/cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . '/cookie.txt');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, '/cookie.txt');
curl_setopt($ch, CURLOPT_POSTFIELDS, "username=USERNAME&password=PASSWORD");
$exec = curl_exec($ch);
curl_setopt($ch, CURLOPT_URL, "http://www.forum.net/reputation.php?uid=" . $uid . "&page=1");
$exec = curl_exec($ch);
echo $exec;
?>

由于某种原因，它不会让我重复使用cookie，而只是让我登录.cook.txt文件包含cookie的东西。

Answer 1

你有：

curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . '/cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . '/cookie.txt');
...[snip]...    
curl_setopt($ch, CURLOPT_COOKIEFILE, '/cookie.txt');

您正在将cookiefile的位置重置为文件系统的根目录，其中Web服务器进程几乎肯定无权编写文件。

同样，请确保网络服务器进程 CAN 在dirname(__FILE__)指向的任何地方写入文件。

Answer 2

您要同时设置CURLOPT_COOKIEJAR和CURLOPT_COOKIEFILE两次，最终结果将是不同的值。 '/cookie.txt'将文件存储在系统根目录中，dirname(__FILE__) . '/cookie.txt'将文件存储在与当前正在执行的脚本相同的目录中。确保您只使用相同的值（可能是后者）设置每个选项一次。

您也使用相同的句柄发出两个请求 - 这不是推荐的方法，并且可能在语义上不正确，因为当第二个应该是GET时，您将最终发布到两个页面。

我建议将cookie jar路径存储在块顶部的变量中，并将其传入。这样可以更容易地看到正在发生的事情。

我怀疑你想要更像这样的东西：

<?php

    // Username and password for login
    $username = 'USERNAME';
    $password = 'PASSWORD';

    // Create the target URLs
    // Don't forget to escape your user input!
    $loginUrl = "http://www.forum.net/member.php?action=do_login";
    $reputationUrl = "http://www.forum.net/reputation.php?uid=" . urlencode($_GET['uid']) . "&page=1";

    // Referer value for login request
    $loginReferer = "http://www.forum.net/member.php?action=login";

    // Note that __DIR__ can also be used in PHP 5.3+
    $cookieJar = dirname(__FILE__) . '/cookie.txt';

    // The User-Agent string to send
    $userAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.56 Safari/536.5";


    // Create the cURL handle for login
    $ch = curl_init($loginUrl);

    // Set connection meta
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    // Set header-related options
    curl_setopt($ch, CURLOPT_REFERER, $loginReferer);
    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieJar);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieJar);

    // Set request body
    $bodyFields = array(
        'username' => $username,
        'password' => $password
    );
    $body = http_build_query($bodyFields);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $body);

    // Execute the request
    if (!curl_exec($ch)) {
        exit("ERROR: Login request failed: " . curl_error($ch));
    }
    curl_close($ch);


    // Create the cURL handle for reputation scrape
    $ch = curl_init($reputationUrl);

    // Set connection meta
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

    // Set header-related options
    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieJar);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieJar);

    // Execute the request
    if (!$result = curl_exec($ch)) {
        exit("ERROR: Reputation scrape request failed: " . curl_error($ch));
    }

    // Output the result
    echo $result;
