使用PHP和Curl登录到Google，是否关闭了Cookie？

Question

我有这段代码可以使用带有curl的Simple DOM Parser登录到Google。我尝试添加cookiejar文件，但无济于事。我不断收到消息：

您的浏览器的cookie功能被关闭。 请打开它。

关于如何解决这个问题的任何想法？

这是我的代码供参考：

$html = file_get_html('https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage');

//... some code for getting post data here

$curl_connection = curl_init('https://accounts.google.com/ServiceLoginAuth');
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl_connection, CURLOPT_COOKIEJAR, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_COOKIEFILE, COOKIEJAR);
curl_setopt($curl_connection, CURLOPT_HEADER, true);  
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_TIMEOUT, 120);
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);

$result = curl_exec($curl_connection);
curl_close($curl_connection);

echo $result;

Answer 1

这是一些经过修改的代码。

它首先请求登录页面获取初始cookie，并提取登录表单所需的值。接下来，它执行登录服务的发布。然后，它检查是否正在尝试使用javascript和meta标签重定向到目标URL。

似乎您已经具有获取表单字段的代码，所以我没有发布我的代码，但是如果您需要它，请告诉我。只要确保$formFields是一个关联数组，其中键是字段名，值是字段值。

<?php

/**
 * Log in to Google account and go to account page

$USERNAME = '[e-mail]';
$PASSWORD = 'password';
$COOKIEFILE = 'cookies.txt';

// initialize curl handle used for all requests
$ch = curl_init();

// set some options on the handle
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $COOKIEFILE);
curl_setopt($ch, CURLOPT_COOKIEFILE, $COOKIEFILE);
curl_setopt($ch, CURLOPT_HEADER, 0);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);

// url of our first request fetches the account login page
curl_setopt($ch, CURLOPT_URL, 
  'https://accounts.google.com/ServiceLogin?hl=en&service=alerts&continue=http://www.google.com/alerts/manage');
$data = curl_exec($ch);

// extract form fields from account login page
$formFields = getFormFields($data);

// inject email and password into form
$formFields['Email']  = $USERNAME;
$formFields['Passwd'] = $PASSWORD;
unset($formFields['PersistentCookie']);

$post_string = http_build_query($formFields); // build urlencoded POST string for login

// set url to login page as a POST request
curl_setopt($ch, CURLOPT_URL, 'https://accounts.google.com/ServiceLoginAuth');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);

// execute login request
$result = curl_exec($ch);

// check for "Redirecting" message in title to indicate success
// based on your language - you may need to change this to match some other string
if (strpos($result, '<title>Redirecting') === false) {
    die("Login failed");
    var_dump($result);
}

// login likely succeeded - request account page; unset POST so we do a regular GET
curl_setopt($ch, CURLOPT_URL, 'https://myaccount.google.com/?utm_source=OGB');
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, null);

// execute request for login page using our cookies
$result = curl_exec($ch);

echo $result;


// helpef functions below

// find google "#gaia_loginform" for logging in
function getFormFields($data)
{
    if (preg_match('/(<form.*?id=.?gaia_loginform.*?<\/form>)/is', $data, $matches)) {
        $inputs = getInputs($matches[1]);

        return $inputs;
    } else {
        die('didnt find login form');
    }
}

// extract all <input fields from a form
function getInputs($form)

    $inputs = array();

    $elements = preg_match_all('/(<input[^>]+>)/is', $form, $matches);

    if ($elements > 0) {
        for($i = 0; $i < $elements; $i++) {
            $el = preg_replace('/\s{2,}/', ' ', $matches[1][$i]);

            if (preg_match('/name=(?:["\'])?([^"\'\s]*)/i', $el, $name)) {
                $name  = $name[1];
                $value = '';

                if (preg_match('/value=(?:["\'])?([^"\'\s]*)/i', $el, $value)) {
                    $value = $value[1];
                }

                $inputs[$name] = $value;
            }
        }
    }

    return $inputs;
