curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（& $ this，'readHeader'））不工作

问题描述

我有这个包装器从Joomla加载symfony项目

  class NZGBCComponentHelper {
 function requestAndFollow path =''）{
 $ c = 0; $ first = 1; $ httpcode = 0; 
 $ uri = JRequest :: getVar（'uri'）; 
 while（$ c< = 4&&（$ first || $ httpcode == 302））{
 $ first = 0; 
 $ finalSfUrl = NZGBCComponentHelper :: buildRequestUri（$ uri，$ path）; 
 
 $ ch = curl_init（$ finalSfUrl）; 
 
 if（JRequest :: getMethod（）=='POST'&& $ httpcode！= 302）{
 curl_setopt（$ ch，CURLOPT_POST，1）; 
 $ postThrough = array_merge（JRequest :: get（$ _ POST），array（'_ csrf_token'=> $ _POST ['_ csrf_token']）））; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，http_build_query（$ postThrough））; 
} 
 
 //获取sf内容
 curl_setopt（$ ch，CURLOPT_REFERER，JURI :: getInstance（） - > root 
 curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，'readHeader'）; 
 curl_setopt（$ ch，CURLOPT_HEADER，1）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，1）; 
 curl_setopt（$ ch，CURLOPT_COOKIE，'symfony ='。$ _ COOKIE ['symfony']）; 
 
 $ return = curl_exec（$ ch）; 
 $ httpcode = curl_getinfo（$ ch，CURLINFO_HTTP_CODE）; 
 
 
 if（！$ return）{
 $ error = curl_error（$ ch）; 
} 
 
 if（$ this-> headers ['Set-Cookie']）{
 JResponse :: setHeader（'Set-Cookie'，$ mainframe-> sym_headers ['Set-Cookie']）; 
} 
 if（$ httpcode> = 400）{
 $ return =有一个<！ -  $ finalSfUrl  - >错误; 
 mail（'[email protected]'，'symfony wrapper error'，
 $ finalSfUrl。\r\\\
。
 $ httpcode。\r\\ \\ n。
 $ return 
）; 
 
} else if（$ httpcode == 302）{
 $ query = parse_url（trim（$ mainframe-> sym_headers ['Location']），PHP_URL_QUERY）; 
 parse_str（$ query）; 
 parse_str（$ uri）; 
 if（$ outside =='true'）{
 JApplication :: redirect（trim（urldecode（$ uri）））; 
} 
} 
 curl_close（$ ch）; 
 $ c ++; 
} 
 return $ return; 
 
} 
} 
 
 if（！function_exists（'readHeader'））{
 function readHeader（$ ch，$ header）{
 
 $ mainframe =& JFactory :: getApplication（）; 
 if（$ pos = strpos（$ header，'：'））{
 $ mainframe-> sym_headers [substr（$ header，0，$ pos）] = substr '：'），1）; 
} 
 
 return strlen（$ header）; 
} 
} 
  

requestAndFollow是静态调用的。如何引用readHeader（）而不是将其放入全局函数空间。我试过：

  curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（& $ this，'readHeader'））; // didn我们希望这个工作 - 没有$这当静态调用
 
 
 curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（'NZGBCComponentHelper'，'readHeader'））; 
 
 
 curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（self，'readHeader'））; 
  

解决方案

$ b

• libcurl 7.19.7，Ubuntu 10.10，PHP 5.3.2

但不在

• Debian Lenny上的libcurl 7.18.2，PHP 5.2.6

这两个版本的工作解决方法是将标题函数放在全局空间中

  curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，'readHeader'）; 
  

I have this wrapper to load a symfony project from within Joomla

class NZGBCComponentHelper {
    function requestAndFollow($path = '') {
        $c = 0;$first = 1;$httpcode = 0;
        $uri = JRequest::getVar('uri');
        while ($c <= 4 && ($first || $httpcode == 302)){
            $first = 0;
            $finalSfUrl = NZGBCComponentHelper::buildRequestUri($uri, $path);

            $ch = curl_init($finalSfUrl);

            if(JRequest::getMethod() == 'POST' && $httpcode != 302){
                curl_setopt($ch, CURLOPT_POST, 1);
                $postThrough = array_merge(JRequest::get($_POST),array('_csrf_token' => $_POST['_csrf_token']));
                curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postThrough));
            }

            // Get sf content
            curl_setopt($ch, CURLOPT_REFERER, JURI::getInstance()->root().$path);
            curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'readHeader');
            curl_setopt($ch, CURLOPT_HEADER, 1);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
            curl_setopt($ch, CURLOPT_COOKIE, 'symfony='.$_COOKIE['symfony']);

            $return = curl_exec($ch);
            $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);


            if (!$return){
                $error = curl_error($ch);
            }

            if($this->headers['Set-Cookie']){
                JResponse::setHeader('Set-Cookie', $mainframe->sym_headers['Set-Cookie']);
            }
            if ($httpcode >= 400){
                $return = "There was an <!--$finalSfUrl-->  error ";
                mail ('[email protected]', 'symfony wrapper error',
                $finalSfUrl."\r\n".
                $httpcode."\r\n".
                $return
                );

            }else if ($httpcode == 302){
                $query = parse_url(trim($mainframe->sym_headers['Location']), PHP_URL_QUERY);
                parse_str($query);
                parse_str($uri);
                if ($outside == 'true'){
                    JApplication::redirect(trim(urldecode($uri)));
                }
            }
            curl_close($ch);
            $c++;
        }
        return $return;

    }
    }

    if (!function_exists('readHeader')){
    function readHeader($ch, $header){

        $mainframe =& JFactory::getApplication();
        if($pos = strpos($header, ':')){
            $mainframe->sym_headers[substr($header, 0, $pos)] = substr(strstr($header, ':'), 1);
        }

        return strlen($header);
    }
}

requestAndFollow is statically called. How can I refer to readHeader() instead of putting it into the global function space. I tried:

curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(&$this,'readHeader'));//didn't expect this to work - no $this when statically called


curl_setopt($ch, CURLOPT_HEADERFUNCTION, array('NZGBCComponentHelper','readHeader'));


curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(self,'readHeader'));

解决方案

It appears this works fine on

• libcurl 7.19.7, Ubuntu 10.10, PHP 5.3.2

but not on

• libcurl 7.18.2 on Debian Lenny, PHP 5.2.6

A working workaround on both versions is to put the header function in the global space

curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'readHeader');
