php - 如何在 PHP 中使用 cURL 将 session 值从一个请求连续传递到另一个请求？

Question

当发出第一个请求时，会创建一个 session ID。相同的 session ID 被携带到第二个请求。

在我的第三个请求中，为成功登录创建了一个新的 session ID，但是当我为第三个请求打印 session ID 时，响应给出了一个不同的 session ID。为什么会这样？我想将我在第 3 次响应中获得的 session ID 发送到第 4 次？

如何实现？

这是我的代码:

<?php
$fp = fopen("cookies.txt", "w");
fclose($fp);
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_HEADER => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_URL => 'https://192.168.2.35/cgi-bin/common/login/webLogin',
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_SSL_VERIFYHOST => false,
    CURLOPT_COOKIESESSION => TRUE,
    CURLOPT_COOKIEFILE => "cookies.txt",
    CURLOPT_COOKIEJAR => "cookies.txt",
    CURLOPT_FOLLOWLOCATION => TRUE,
    CURLOPT_AUTOREFERER => TRUE,
));
$result = curl_exec($curl);

if (!curl_exec($curl))
{
    die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}

echo "<h2>Response 1</h2>";
print_r($result);
$cookies = curl_getinfo($curl, CURLINFO_COOKIELIST);
print_r($cookies);

$fields = array(
    'userName' => 'dadmin',
    'logonButton' => 'Logon',
    'actionStep' => 2,
);
$fields_string = http_build_query($fields);
curl_setopt_array($curl, array(
    CURLOPT_HEADER => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_URL => 'https://192.168.2.35/cgi-bin/common/login/webLogin',

$resp = curl_exec($curl);

if (!curl_exec($curl))
{
    die('Error: "' . curl_error($curl) . '" - Code: ' . curl_errno($curl));
}

echo "<h2>Response 2</h2>";
print_r($resp);
$cookies = curl_getinfo($curl, CURLINFO_COOKIELIST);
print_r($cookies);

您必须在每个请求中指定 cookie 文件，而不仅仅是在前一两个请求中:

CURLOPT_COOKIEFILE => "/tmp/cookies.txt",
CURLOPT_COOKIEJAR => "/tmp/cookies.txt",

还要确保文件实际上是可写的:

$cookieFile = '/tmp/cookies.txt';
if (! is_readable($cookieFile) || ! is_writable($cookieFile)) {
    throw new \Exception(
        'Cookiefile ' . $cookieFile . ' is not writable or readable.'
    );
}
