php curl multipart / form-data proxy-authorization（basic）

我有一个问题：我试图发送 Headers ，但没有任何反应 .

这是“Live HTTPHeaders” Headers 的一部分（我替换了url）：

http://some_site/news/

HTTP/1.1 302 Found

这是我的代码：

<?php

 $parent = 155129;

 function doPost( $url = 'http://some_site/news', $postdata = '' ){

 $resource = curl_init();
 curl_setopt($resource, CURLOPT_URL, $url);
 curl_setopt($resource, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt ($resource, CURLOPT_SSL_VERIFYPEER, 0);
 curl_setopt ($resource, CURLOPT_SSL_VERIFYHOST, 0);
 curl_setopt ($resource, CURLOPT_HTTPHEADER, array('Expect:'));
 curl_setopt ($resource, CURLOPT_HEADER, 1);
 curl_setopt ($resource, CURLOPT_COOKIEJAR, 'cookie.txt');
 curl_setopt($resource,CURLOPT_COOKIEFILE,'cookie.txt');
 curl_setopt($resource, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
 if( $postdata != '' ) {
     curl_setopt($resource, CURLOPT_POST, true);
     curl_setopt($resource, CURLOPT_POSTFIELDS, $postdata);
 }
 curl_setopt($resource, CURLOPT_FOLLOWLOCATION, true);
 $result = curl_exec($resource);
 curl_close($resource);
 return $result;

}

$c = doPost();
preg_match('#id="textarea_form_'.$parent.'" name="(.*?)"#ims', $c, $textName);
preg_match('#<form.*?\/form>#ims', $c, $arr );
preg_match('#name=eggs2.*?value="(.*?)">#ims', $arr[0], $egss2);

$postdata = array(
    $textName[1]=> 'Hello',
   'file'=>'@/;type=application/octet-stream',
   'parent' => $parent,
   'redirect'=> '0',
   'eggs2' => $egss2[1],
   'submit' => iconv('utf-8', 'cp1252', 'Добавить')
);

print_r(doPost('http://some_site/news',$postdata));
print_r( $postdata );

我做错了什么？
