从头字符串中获取PHP Cookies

Question

我有一个包含头部响应的字符串变量，就像这样

通过fsockopen()发送请求并获取头部，可以捕获此字符串。

$nn= "\r\n";
    do {
        $header .= fgets ( $fp, 16384 );
    } while ( strpos ( $header, $nn . $nn ) === false );

输出：

$header = "HTTP/1.0 200 OK Date: Tue, 13 Sep 2011 07:57:08 GMT Last-Modified: Tue, 13 Sep 2011 07:57:08 GMT

";

现在我想将所有的cookie存储到一个数组中

$cookie[1] = "EUID=face313a-dddd-11e0-a694-00000aab0f6c";
$cookie[2] = "MIAMISESSION=face28e8-dddd-11e0-a694-00000aab0f6c:3493353428";
...

我该如何做到这一点？这是正则表达式的工作还是有一个类或函数可以使这更容易？

另一种方法：

    $headerCookies = explode('; ', getallheaders()['Cookie']);

    $cookies = array();

    foreach($headerCookies as $itm) {
        list($key, $val) = explode('=', $itm, 2);
        $cookies[$key] = $val;
    }
    
    print_r($cookies); // assoc array of all cookies

Answer 2

我使用了以下代码：

$domain = "www.google.com";

// open the socket
$f = @stream_socket_client($domain . ":80", $err, $errstr, 30, STREAM_CLIENT_CONNECT);

if(!$f)
  die("Error: " . $err . $errstr);

// prepare the HTTP request headers
$request_headers  = "GET / HTTP/1.1" . "\r\n";
$request_headers .= "Host: " . $domain . "\r\n";
$request_headers .= "Connection: close" . "\r\n";
$request_headers .= "\r\n";

// send the HTTP request
fputs ($f, $request_headers);

// read everything from the socket
$buf = "";
while (!feof($f)) {
  $buf .= fgets ($f, 8192);
}

// close the socket
fclose($f);

// split the headers and the body
$response = preg_split("|(?:\r?\n){2}|m", $buf, 2);
if(!isset($response[1]))
  $response[1] = "";

$headers = array();
$content = $response[1];

$out = preg_split("|(?:\r?\n){1}|m", $response[0]);
foreach($out as $line){
  @list($key, $val) = explode(": ", $line, 2);
  if ($val != null) {
    if(!array_key_exists(strtolower($key), $headers))
      $headers[strtolower($key)] = strtolower(trim($val));
  } else 
    $headers[] = $key;
}

// now you have the response headers in an array
print_r($headers);

接下来要做的是获取存储为字符串值的每个cookie并解析它。为了实现这一点，我使用了一个从Zend Framework中复制的函数fromString(): http://www.sourcexref.com/xref/moodle/nav.html?lib/zend/Zend/Http/Cookie.php.source.html#l274。

祝你好运。

附注：此行代码$headers[strtolower($key)] = strtolower(trim($val));将覆盖服务器发送两次的头参数的值。

即：

...
Connection: close
Expires: -1
Connection: close
Cache-control: private, max-age=0
...

Answer 3

使用http_parse_headers()函数。

要使用**http_parse_headers()**函数，您必须安装PECL扩展... - Cristian Ciocău

Answer 4

另一种简短的方式：

if(preg_match_all('/Set-Cookie:[\s]([^;]+)/', $header, $matches)){
    $cookies = $matches[1];
}

它会给你完全想要的东西。
