php设置http请求头信息和响应头信息 设置请求服务器的头信息可以用fsockopen,curl组件,header函数只能用来设置客户端响应的头信息，不能设置服务器的头信息. 例子; 一.header函数的用法 header('WWW-Authenticate: Negotiate'); header('User-Agent:Mozilla/5.0); 多个直接要写多个header,不可以连接在一起 二.fsockopen函数的用法 1.php <?php $fp = fsockopen("test.com", 80, $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)
\n"; } else { $out = "GET /2.php HTTP/1.1\r\n"; $out .= "Host: test.com\r\n"; $out .= "name:longqiqi\r\n"; $out .= "Connection: Close\r\n\r\n"; fwrite($fp, $out); while (!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } ?> 2.php print_r(getallheaders()); 会返回自己设置请求的头信息 三.curl组件的使用 1.php <?php function FormatHeader($url, $myIp = null,$xml = null) { // 解悉url $temp = parse_url($url); $query = isset($temp['query']) ? $temp['query'] : ''; $path = isset($temp['path']) ? $temp['path'] : '/'; $header = array ( "POST {$path}?{$query} HTTP/1.1", "Host: {$temp['host']}", "Content-Type: text/xml; charset=utf-8", 'Accept: */*', "Referer: http://{$temp['host']}/", 'User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1)', "X-Forwarded-For: {$myIp}", "Content-length: 380", "Connection: Close" ); return $header; } $interface = 'http://test.com/2.php'; $header = FormatHeader($interface,'10.1.11.1'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $interface); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置头信息的地方 curl_setopt($ch, CURLOPT_HEADER, 0); //不取得返回头信息 curl_setopt($ch, CURLOPT_TIMEOUT, 5); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($ch); var_dump($result); ?> 2.php print_r(getallheaders()); 会返回自己设置请求的头信息 #Php
