curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（& $ this，'readHeader'））不工作 [英] curl_setopt($ch, CURLOPT_HEADERFUNCTION, array(&$this,'readHeader')) not working
本文介绍了curl_setopt（$ ch，CURLOPT_HEADERFUNCTION，array（& $ this，'readHeader'））不工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
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（'jd@automatem.co.nz'，'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 ('jd@automatem.co.nz', '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');
