PHP Curl - 修改 cookie 而不是添加新的

Question

我打开了 curl 会话，它设置了 cookie 文件，因此它会记住会话 ID（来自登录）。但是我现在如何修改这些 cookie？

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Cookie:blabla=bleble'));

似乎动作不正确，因为它添加了另一个 Cookie 标头，所以如果我在请求标头之间有：

...
Cookie:blabla=uhuhu;tralala=ahahaha
...

我运行这个：

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Cookie:blabla=bleble'));

它将简单地添加另一个具有相同变量但值不同的 Cookie 标头：

...
Cookie:blabla=uhuhu;tralala=ahahaha
...
Cookie:blabla=bleble

那么如何修改现有的 Cookie 而不是添加另一个 Cookie 标头？

例如，当我登录网站时，将会话 cookie 保存在文件中，并且在第二个请求中想要替换它时，我会得到这样的信息（正在发送）：

替换为CURLOPT_HTTPHEADER

curl_setopt($curl, CURLOPT_HTTPHEADER, 'Cookie: 46db1eb1/sessid=blabla; 46db1eb1/zoom-accessibility=small');

如您所见 - cookie 加倍。

替换为CURLOPT_COOKIE时

curl_setopt($curl, CURLOPT_COOKIE, '46db1eb1/sessid=blabla; 46db1eb1/zoom-accessibility=small');

相同的 cookie 标头中的值加倍。

您可以操作CURLOPT_COOKIEJAR 文件。像这样的：

<?php
function init($f)
{
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, "http://localhost/a.php");
    curl_setopt($curl, CURLOPT_COOKIEJAR, $f);
    curl_setopt($curl, CURLOPT_COOKIEFILE, $f);
    return $curl;
}
function readCookies($f)
{
    $cookies = [];
    if (($handle = fopen($f, "r")) !== FALSE) {
        while (($cookie = fgetcsv($handle, 1000, "\t")) !== FALSE) {
            $cookies[] = $cookie;
        }
        fclose($handle);
    }
    return $cookies;
}
function writeCookies($f, $c)
{
    $fp = fopen($f, "w");

    foreach ($c as $cookie) {
        fputcsv($fp, $cookie, "\t");
    }

    fclose($fp);
}

$f = './c.tmp';
$curl = init($f);
curl_exec($curl);

// playing with cookies:
$newCookie = ['blabla', '123'];
$cookies = readCookies($f);
if (!empty($cookies)) {
    $found = false;
    foreach($cookies as $key=>$val) {
        // ignore comments and empty lines
        if (count($val) == 7) {
            if ($val[5] == $newCookie[0]) {
                $found = $key;
                break;
            }
        }
    }
    if ($found) {
        $cookies[$found][6] = $newCookie[1];
    } else {
        // I am using first one as a template,
        // but you may need to set all fields explicitly
        // as they may differ
        $cookie = $cookies[0];
        $cookie[5] = $newCookie[0];
        $cookie[6] = $newCookie[1];
        $cookies[] = $cookie;
    }
    writeCookies($f, $cookies);
}

$curl = init($f);
if (empty($cookies)) {
    curl_setopt($curl, CURLOPT_HTTPHEADER, array('Cookie:blabla=123'));
}
curl_exec($curl);
