这篇文章主要介绍了php自定义类fsocket模拟post或get请求的方法,涉及php使用socket模拟post及get请求的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了php自定义类fsocket模拟post或get请求的方法。分享给大家供大家参考。具体如下：
zsocket.class.php文件如下：
_setCookie(substr($line, 12)); } $reHeader .= $line; if(substr($line, 0, 16) == 'Content-Length: '){ $maxlen = intval(substr($line, 16, -2)); } if($line == "\r\n" || $line == "") break; } return $maxlen; } /* * 获取返回数据正文内容 */ private function _getDataBody(&$fp,$maxlen){ $reData = ""; while(!feof($fp)){ $line = fgets($fp,$maxlen+1); $reData .= $line; if(strlen($line) $value){ $_params .= "&".$key."=".urlencode($value); } $_params = (strlen($_params) > 1) ? substr($_params,1) : ''; }else if(is_string($params)){ $_params = urlencode($params); } foreach($cookies as $key=>$value){ $_cookies .= "; ".$key."=".urlencode($value); } $_cookies = (strlen($_cookies) > 2) ? substr($_cookies,2) : ''; $file .= ($type == 'GET') ? ($_params == '' ? '' : '?'.$_params) : ''; $header = $type." ".$file." HTTP/1.1\r\n"; $header .= "Host: ".$host."\r\n"; //$header .= "Referer: ".get_ip()."\r\n"; //$header .= "X-Forwarded-For: ".get_ip()."\r\n"; $header .= ($type == 'GET') ? '' : "Content-Type: application/x-www-form-urlencoded\r\n"; if(is_array($head) && $head != array()){ foreach($head as $k=>$v){ $header .= $k.": ".$v."\r\n"; } } $header .= "Content-Length: ".strlen($_params)."\r\n"; if($_cookies != '') $header .= "Cookie: ".$_cookies."\r\n"; /* foreach($_SERVER as $name => $value){ if(substr($name, 0, 5) == 'HTTP_' && $name != 'HTTP_HOST'){ $header .= str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5))))).":".$value."\r\n"; } } */ $header .= "Connection: Close\r\n\r\n"; $header .= $_params."\r\n"; return $header; } /* * 发送,并返回结果 Array */ public function get_SendData($host,$port=80,$header=''){ if(function_exists('fsockopen')){ $fp = fsockopen($host,$port,$errno,$errstr,10); }else if(function_exists('pfsockopen')){ $fp = pfsockopen($host,$port,$errno,$errstr,10); }else if(function_exists('stream_socket_client')){ $fp = stream_socket_client($host.':'.$port,$errno,$errstr,10); }else{ $fp = $this->_fsockopen($host,$port,$errno,$errstr,10); } $fp = fsockopen($host,$port,$errno,$errstr,10); if(!$fp) return array('header'=>'','data'=>$errstr."--->".$errno,'cookie'=>''); $reHeader = $reData = ""; $cookies = array(); fputs($fp,$header); $maxlen = $this->_getDataHeader($fp,$reHeader,$cookies); $reData = $this->_getDataBody($fp,$maxlen); fclose($fp); return array('header'=>$reHeader,'data'=>$reData,'cookie'=>$cookies); } }
demo代码如下：
$host = 'www.jb51.net'; $port = '80'; $type = 'POST'; $file = 'http://www.jb51.net/'; $params = ''; //include_once('include/zsocket.class.php'); //include $zsk = new ZSocket(); $header = $zsk->get_HeaderInfo($host,$type,$file,$params); $data = $zsk->get_SendData($host,$port,$header); /* echo "\r\n"; */ var_dump($header); var_dump($data);
希望本文所述对大家的php程序设计有所帮助。
