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;}?>
