除了CURLOPT_COOKIEFILE之外,我如何使用PHP curl发送cookie?

标签: php cookies curl setcookie

我在提交表单后从网站上抓取一些内容。问题是脚本时不时地失败,比如说5个脚本失败了2次。我正在使用php curl,COOKIEFILE和COOKIEJAR来处理cookie。但是,当我观察我的浏览器发送的标题(从我的浏览器访问目标网站并使用实时http标头)和php发送的标题时,看到有很多不同之处。

我的浏览器发送了比php curl更多的cookie变量。我认为这种差异可能是因为javascript可用于设置大多数cookie,但我不确定这一点。

我正在使用以下代码进行抓取,我正在显示我的浏览器和php curl的已发送标头:

$ckfile = tempnam ("/tmp", 'cookiename');

$url = 'https://www.domain.com/firststep';
$poststring = 'variable1=4&variable2=5';
$ch = curl_init ($url);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $poststring);
$output = curl_exec ($ch);
curl_close($ch);



$url = 'https://www.domain.com/nextstep';
$poststring = 'variableB1=4&variableB2=5';
$ch = curl_init ($url);
curl_setopt ($ch, CURLOPT_COOKIEJAR, $ckfile);
curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $poststring);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
$output = curl_exec ($ch);
$headers = curl_getinfo($ch, CURLINFO_HEADER_OUT);
curl_close($ch);

print_r($headers);

我想用:

$headers   = array();
$headers[] = 'Cookie: ' . $cookie;

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

其中:

$cookie = 'subdomainPARTNER=NSINT; JSESSIONID=CB3FEB3AC72AD61A80BFED91D3FD96CA; www-20480=MHFBNLFDFAAA; campaignPos=5; www-47873=MGFBNLFDFAAA; __utma=1.993399624.1370027094.1370040145.1370082133.5; __utmc=1; __utmz=1.1370027094.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); BCSessionID=5dc05787-c2c8-43e1-9abe-93989970b087; BCPermissionLevel=PERSONAL; __utmb=1.1.10.1370082133';

我上面的cookie中的一些参数可能会从网站的内容中删除,但不是全部。其中一些我可以从$ ckfile中读取,但我不知道该怎么做。尤其是utma utmc,utmz,utmcsr,utmccn,utmcmd我无法从任何地方获取,我认为这些都是由javascript生成的。

问题1: 我在当前代码中处理cookie时出错了,因为很少有cookie变量是由php curl发送的,浏览器还有很多?进一步:浏览器和php curl发送的标题之间的其他差异是否能够返回正确的内容?

问题2: 由于javascript设置了这些cookie,是否缺少cookie变量?

问题3: 处理cookie以确保将所有必需的cookie发送到远程服务器的最佳方法是什么?

非常欢迎你的帮助!

如果cookie是从脚本生成的,那么您可以手动将cookie与文件中的cookie一起发送(使用cookie-file选项)。例如:

# sending manually set cookie
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie: test=cookie"));

# sending cookies from file
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile);

在这种情况下,curl会将您定义的cookie与文件中的cookie一起发送。

如果cookie是通过javascrript生成的,那么你必须追踪它是如何生成的,然后你可以使用上面的方法(通过http-header)发送它。

从Mozilla发送Cookie时会看到utma utmc, utmz。你不应该再担心这些事了。

最后,你做的方式没问题。只需确保使用文件名的绝对路径(即/var/dir/cookie.txt)而不是相对路径。

使用curl时始终启用详细模式。它将帮助您追踪请求。它也会节省你的很多时间。

curl_setopt($ch, CURLOPT_VERBOSE, true);

尝试以下代码,

$cookieFile = "cookies.txt";
if(!file_exists($cookieFile)) {
    $fh = fopen($cookieFile, "w");
    fwrite($fh, "");
    fclose($fh);
}


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiCall);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile); // Cookie aware
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); // Cookie aware
curl_setopt($ch, CURLOPT_VERBOSE, true);
if(!curl_exec($ch)){
    die('Error: "' . curl_error($ch) . '" - Code: ' . curl_errno($ch));
}
else{
    $response = curl_exec($ch); 
}
curl_close($ch);
$result = json_decode($response, true);

echo '<pre>';
var_dump($result);
echo'</pre>';

我希望这会对您有所帮助。

最好的问候, 达西莎。

以下是发送Cookie的示例列表-https://github.com/andriichuk/php-curl-cookbook#cookies

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://httpbin.org/cookies',
CURLOPT_RETURNTRANSFER => true,

CURLOPT_COOKIEFILE  => $cookieFile,
CURLOPT_COOKIE => 'foo=bar;baz=foo',

/**
 * Or set header
 * CURLOPT_HTTPHEADER => [
       'Cookie: foo=bar;baz=foo',
   ]
 */
]);

$response = curl_exec($curlHandler);
curl_close($curlHandler);

echo $response;

我认为您需要的唯一Cookie是JSESSIONID = xxx ..

也绝不分享您的cookies,因为有人可能会以这种方式访问​​您的个人数据。特别是当cookie是会话时。一旦您退出网站,这些cookie将停止工作。
