如何從一個PHP捲曲獲取cookie到一個變量

Question

所以一些其他公司的人認爲這將是可怕的，而不是使用soap或xml-rpc或休息或任何其他合理的通信協議，他只是嵌入他的所有響應作爲標頭中的Cookie。

我需要從這個捲曲響應中拉出這些cookie作爲希望的數組。如果我不得不浪費大量時間爲此寫一個解析器，我會很不高興。

有誰知道這可以簡單地完成，最好不寫任何文件？

如果有人能幫助我解決這個問題，我將不勝感激。

Answer 1

$ch = curl_init('http://www.google.com/'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
// get headers too with this line 
curl_setopt($ch, CURLOPT_HEADER, 1); 
$result = curl_exec($ch); 
// get cookie 
// multi-cookie variant contributed by @Combuster in comments 
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $matches); 
$cookies = array(); 
foreach($matches[1] as $item) { 
    parse_str($item, $cookie); 
    $cookies = array_merge($cookies, $cookie); 
} 
var_dump($cookies); 

Answer 2

如果使用CURLOPT_COOKIE_FILE和CURLOPT_COOKIE_JAR，curl將從文件讀取/寫入cookie。您可以在捲曲完成後，根據需要閱讀和/或修改它。

Answer 3

我的理解是，必須將curl的cookies寫入文件（curl -c cookie_file）。如果你正在運行curl通過PHP的exec或system功能（或該族中的任何東西），你應該能夠餅乾保存到一個文件，然後打開文件，並在閱讀它們。

Answer 4

的libcurl也提供CURLOPT_COOKIELIST，提取所有已知的Cookie。所有你需要的是確保PHP/CURL綁定可以使用它。

Answer 5

這樣做沒有正則表達式，但需要PECL HTTP extension。

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_HEADER, 1); 
$result = curl_exec($ch); 
curl_close($ch); 

$headers = http_parse_headers($result); 
$cookobjs = Array(); 
foreach($headers AS $k => $v){ 
    if (strtolower($k)=="set-cookie"){ 
     foreach($v AS $k2 => $v2){ 
      $cookobjs[] = http_parse_cookie($v2); 
     } 
    } 
} 

$cookies = Array(); 
foreach($cookobjs AS $row){ 
    $cookies[] = $row->cookies; 
} 

$tmp = Array(); 
// sort k=>v format 
foreach($cookies AS $v){ 
    foreach ($v AS $k1 => $v1){ 
     $tmp[$k1]=$v1; 
    } 
} 

$cookies = $tmp; 
print_r($cookies); 

Answer 6

雖然這個問題很老了，該接受的反應是有效的，我覺得有點unconfortable因爲HTTP響應的內容（HTML，XML，JSON，二進制或其他）變得與頭混合。

我發現了另一種選擇。 CURL提供了一個選項（CURLOPT_HEADERFUNCTION）來設置將針對每個響應標題行調用的回調。該函數將收到curl對象和一個帶有標題行的字符串。

您可以使用這樣的代碼（改編自TML響應）：

$cookies = Array(); 
$ch = curl_init('http://www.google.com/'); 
// Ask for the callback. 
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "curlResponseHeaderCallback"); 
$result = curl_exec($ch); 
var_dump($cookies); 

function curlResponseHeaderCallback($ch, $headerLine) { 
    global $cookies; 
    if (preg_match('/^Set-Cookie:\s*([^;]*)/mi', $headerLine, $cookie) == 1) 
     $cookies[] = $cookie; 
    return strlen($headerLine); // Needed by curl 
} 

該解決方案使用全局變量的缺點，但我想這不是短期腳本的問題。如果curl被封裝到一個類中，你總是可以使用靜態方法和屬性。

某人在這裏可能會覺得它有用。 hhb_curl_exec2與curl_exec非常類似，但arg3是一個數組，它將填充返回的http頭（數字索引），而arg4是一個數組，它將填充返回的cookie（$ cookies [「expires」] =>「星期五，06-May-2016 05:58:51 GMT「），並且arg5將填充... curl提供的原始請求信息。

的缺點是，它需要CURLOPT_RETURNTRANSFER要上，否則報錯了，而且它會覆蓋CURLOPT_STDERR 和 CURLOPT_VERBOSE，如果你已經在使用別的東西..（我以後可能會解決這個問題），如何使用它

例如：

<?php 
header("content-type: text/plain;charset=utf8"); 
$ch=curl_init(); 
$headers=array(); 
$cookies=array(); 
$debuginfo=""; 
$body=""; 
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); 
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); 
$body=hhb_curl_exec2($ch,'https://www.youtube.com/',$headers,$cookies,$debuginfo); 
var_dump('$cookies:',$cookies,'$headers:',$headers,'$debuginfo:',$debuginfo,'$body:',$body); 

和功能本身..

function hhb_curl_exec2($ch, $url, &$returnHeaders = array(), &$returnCookies = array(), &$verboseDebugInfo = "") 
{ 
    $returnHeaders = array(); 
    $returnCookies = array(); 
    $verboseDebugInfo = ""; 
    if (!is_resource($ch) || get_resource_type($ch) !== 'curl') { 
     throw new InvalidArgumentException('$ch must be a curl handle!'); 
    } 
    if (!is_string($url)) { 
     throw new InvalidArgumentException('$url must be a string!'); 
    } 
    $verbosefileh = tmpfile(); 
    $verbosefile = stream_get_meta_data($verbosefileh); 
    $verbosefile = $verbosefile['uri']; 
    curl_setopt($ch, CURLOPT_VERBOSE, 1); 
    curl_setopt($ch, CURLOPT_STDERR, $verbosefileh); 
    curl_setopt($ch, CURLOPT_HEADER, 1); 
    $html    = hhb_curl_exec($ch, $url); 
    $verboseDebugInfo = file_get_contents($verbosefile); 
    curl_setopt($ch, CURLOPT_STDERR, NULL); 
    fclose($verbosefileh); 
    unset($verbosefile, $verbosefileh); 
    $headers  = array(); 
    $crlf   = "\x0d\x0a"; 
    $thepos  = strpos($html, $crlf . $crlf, 0); 
    $headersString = substr($html, 0, $thepos); 
    $headerArr  = explode($crlf, $headersString); 
    $returnHeaders = $headerArr; 
    unset($headersString, $headerArr); 
    $htmlBody = substr($html, $thepos + 4); //should work on utf8/ascii headers... utf32? not so sure.. 
    unset($html); 
    //I REALLY HOPE THERE EXIST A BETTER WAY TO GET COOKIES.. good grief this looks ugly..

Answer 8

curl_setopt($ch, CURLOPT_HEADER, 1); 
    //Return everything 
    $res = curl_exec($ch); 
    //Split into lines 
    $lines = explode("\n", $res); 
    $headers = array(); 
    $body = ""; 
    foreach($lines as $num => $line){ 
     $l = str_replace("\r", "", $line); 
     //Empty line indicates the start of the message body and end of headers 
     if(trim($l) == ""){ 
      $headers = array_slice($lines, 0, $num); 
      $body = $lines[$num + 1]; 
      //Pull only cookies out of the headers 
      $cookies = preg_grep('/^Set-Cookie:/', $headers); 
      break; 
     } 
    }
