PHP - 使用cURL将cookie会话存储到变量/内存中 [英] PHP - Using cURL to store cookie session into variable / memory

问题描述

我试图避免cURL通过CURLOPT_COOKIEJAR将cookie会话存储到实际文件中。所以我创建了一个方法来捕获/解析cookie到一个局部变量 - 然后通过CURLOPT_COOKIE来恢复cookie会话。

I'm trying to avoid cURL storing the cookie session into an actual file via "CURLOPT_COOKIEJAR". So I created a method to catch / parse the cookies into a local variable - which is then used via "CURLOPT_COOKIE" to restore the cookie session.

通过

preg_match_all("/^Set-cookie: (.*?);/ism", $header, $cookies);

要使用CURLOPT_COOKIE，我们取key = value，并通过;分隔。但是（我知道），CURLOPT_COOKIE不允许你抛出各种标志。到期，安全标志等。

To use "CURLOPT_COOKIE" we take the key=value and separate them via "; ". However (As I'm aware), CURLOPT_COOKIE doesn't allow you throw in various flags I.e. expiration, secure flag, and so on.

问题实际发生在CURLOPT_FOLLOWLOCATION发生的地方。我不认为它与标志有关。它似乎不像手动cookie会话，我有更新时，当一个新的位置（即一个网站有2-3重定向附加各种cookie /会话）。这实际上是有意义的，因为利用CURLOPT_COOKIEJAR将直接抓取/更新在标题重定向发送的cookie。所以，我试图创建一个手动重定向路径，同时抓取/附加最新的cookie - 但是这种方法不工作的一些明确的原因。

So I think my issue actually occurs where CURLOPT_FOLLOWLOCATION occurs. I don't think it has to do with the flags. It doesn't seem like the manual cookie session I have is updating when following a new location (i.e. a site has 2-3 redirects to append various cookies / session). Which would actually make sense because utilizing CURLOPT_COOKIEJAR will directly grab / update cookies sent on header redirects. So, I tried creating a manual redirection path while grabbing / appending the latest cookie - however this method did not work for some plain reason.

几乎有了这个想法。将很快更新答案。

Almost got this figured out. Will be updating with answer shortly. It turns out my method works perfectly fine, it's just a matter of jumping through the manual redirected pages correctly.

推荐答案

和我的假设是正确的。

1. 将Cookie会话保存在变量中（与CURLOPT_COOKIEJAR相比）。 *请确保您已启用CURLOPT_HEADER和CURLINFO_HEADER_OUT。*

1. To keep the cookie session in a variable (vs. CURLOPT_COOKIEJAR). *Make sure you have CURLOPT_HEADER and CURLINFO_HEADER_OUT enabled.*

CURLOPT_FOLLOWLOCATION必须设置为false。否则您的Cookie将无法正确发送（这是CURLOPT_COOKIEJAR最好的地方）。

CURLOPT_FOLLOWLOCATION must be set to false. Otherwise your cookie won't send correctly (This is where CURLOPT_COOKIEJAR does best).

使用preg_match_all提取Cookie。然后使用strpos找到第一次出现的=。一些网站使用编码，并包含=的，将无法使用爆炸。

Use preg_match_all to extract cookies. Then use strpos to find the first occurence of "=". Some sites use encoding and include "="'s which won't work with "explode".

$data        = curl_exec($curl);
$header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);
$header      = substr($data, 0, $header_size);

preg_match_all("/^Set-cookie: (.*?);/ism", $header, $cookies);
foreach( $cookies[1] as $cookie ){
    $buffer_explode = strpos($cookie, "=");
    $this->cookies[ substr($cookie,0,$buffer_explode) ] = substr($cookie,$buffer_explode+1);
}

进行下一个curl调用时， / object into CURLOPT_COOKIE。

When making your next curl call, re-call the cookie var/object into CURLOPT_COOKIE.

if( count($this->cookies) > 0 ){
    $cookieBuffer = array();
    foreach(  $this->cookies as $k=>$c ) $cookieBuffer[] = "$k=$c";
    curl_setopt($curl, CURLOPT_COOKIE, implode("; ",$cookieBuffer) );
}
