php curl post请求中携带header参数? 400 报错

curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml")); 

或者

  $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; 
  $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; 
  $header[] = "Cache-Control: max-age=0"; 
  $header[] = "Connection: keep-alive"; 
  $header[] = "Keep-Alive: 300"; 
  $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; 
  $header[] = "Accept-Language: en-us,en;q=0.5"; 
  $header[] = "Pragma: "; // browsers keep this blank. 
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header); 

可以，但是服务端能识别不。不知道你用的啥web server。apache有个方法

$snoopy->proxy_host = "www.proxy.com";    
$snoopy->proxy_port = "8080";

$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)";   
//这里设置来路 
$snoopy->referer = "http://www.baidu.com/";   
//这里设置cookie
$snoopy->cookies["SessionID"] = 238472834723489l;    
$snoopy->cookies["favoriteColor"] = "RED";   
   
//这里设置header
$snoopy->rawheaders["Pragma"] = "no-cache"; //cache 的http头信息   
$snoopy->rawheaders["X_FORWARDED_FOR"] = "127.0.0.101"; //伪装ip
