php curl post请求中携带header参数

php curl post请求中携带header参数

$url = 'http://localhost/test.php';
$ch = curl_init ();
// curl_setopt ( $ch, CURLOPT_HTTPHEADER, $header );
curl_setopt ( $ch, CURLOPT_HTTPHEADER, array (
'X-ptype: like me' 
) );
curl_setopt ( $ch, CURLOPT_POST, count ( $post_data ) );
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, http_build_query ( $post_data ) );
ob_start ();
curl_exec ( $ch );
$result = ob_get_contents ();
ob_end_clean ();
curl_close ( $ch );

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); 

php://input

php://input是个可以访问请求原始数据的只读流，但是对于enctype=”multipart/form-data”表单数据也是不可用的（同$HTTP_RAW_POST_DATA）。

如果PHP使用php://input来处理post数据，请求报文中不需要添加Content-Type头

    <?php
 public function request_post(){
 echo file_get_contents('php://input');
 }
 ?>

PHP 处理Request header

在PHP里，想要得到所有的HTTP请求报头，可以使用getallheaders方法，不过此方法并不是在任何环境下都存在，比如说，你使用fastcgi方式运行php的话，就没有这个方法，所以说我们还需要考虑别的方法，幸运的是$_SERVER里有我们想要的东西，它里面键名以HTTP_开头的就是HTTP请求头：

$headers = array(); 
foreach ($_SERVER as $key => $value) { 
    if ('HTTP_' == substr($key, 0, 5)) { 
        $headers[str_replace('_', '-', substr($key, 5))] = $value; 
        echo "$key: $value\n";
    } 
}

php发送post请求的三种方法,分别使用curl、file_get_content、fsocket来实现post提交数据

/** * 发送post请求
 * @param string $url 请求地址 
 * @param array $post_data post键值对数据
 * @return string 
 * */
 function send_post($url, $post_data) {
     $postdata = http_build_query($post_data);  
        'http' => array(      'method' => 'POST', 
        'header' => 'Content-type:application/x-www-form-urlencoded',     
        'content' => $postdata,    
        'timeout' => 15 * 60 // 超时时间（单位:s）
         ));
       $context = stream_context_create($options); 
       return $result;
  } 
//使用方法
$post_data = array('password' =>'handan');
send_post('http://www.jb51.net', $post_data); 

<?php
/** 
* Socket版本 
* $post_string = "app=socket&version=beta"; 
* request_by_socket('chajia8.com', '/restServer.php', $post_string); 
* /
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30) 
{  
  $socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);
  if (!$socket) die("$errstr($errno)");
  fwrite($socket, "POST $remote_path HTTP/1.0");
  fwrite($socket, "HOST: $remote_server");
  fwrite($socket, "Content-length: " . （strlen($post_string) + 8） . "");
  fwrite($socket, "");
  fwrite($socket, "");
  while ($str = trim(fgets($socket, 4096))) 
  {
      $header .= $str;
  }
   $data = "";
  while (!feof($socket)) 
  {    
      $data .= fgets($socket, 4096);
  }
return $data;
}
?>
