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,16) == 'Content-Length: '){ $maxlen = intval(substr($line,16,-2)); } if($line == "rn" || $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) < $maxlen) $maxlen = $maxlen - strlen($line); else break; } return $reData; } /* * 设置并返回要发送的header内容 */ public function get_HeaderInfo($host,$type='GET',$file='/',$params=array(),$head=array(),$cookies=array()){ $_params = $_cookies = ''; if(is_array($params)){ foreach($params as $key=>$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/1.1rn"; $header .= "Host: ".$host."rn"; //$header .= "Referer: ".get_ip()."rn"; //$header .= "X-Forwarded-For: ".get_ip()."rn"; $header .= ($type == 'GET') ? '' : "Content-Type: application/x-www-form-urlencodedrn"; if(is_array($head) && $head != array()){ foreach($head as $k=>$v){ $header .= $k.": ".$v."rn"; } } $header .= "Content-Length: ".strlen($_params)."rn"; if($_cookies != '') $header .= "Cookie: ".$_cookies."rn"; /* foreach($_SERVER as $name => $value){ if(substr($name,5) == 'HTTP_' && $name != 'HTTP_HOST'){ $header .= str_replace(' ','-',ucwords(strtolower(str_replace('_',' ',substr($name,5))))).":".$value."rn"; } } */ $header .= "Connection: Closernrn"; $header .= $_params."rn"; 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,$errno,$errstr,10); }else if(function_exists('pfsockopen')){ $fp = pfsockopen($host,10); }else if(function_exists('stream_socket_client')){ $fp = stream_socket_client($host.':'.$port,10); }else{ $fp = $this->_fsockopen($host,10); } $fp = fsockopen($host,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'=>$cookies); } }demo代码如下： get_HeaderInfo($host,$type,$file,$params);
$data = $zsk->get_SendData($host,$header);
/*
echo "rn";
*/
var_dump($header);
var_dump($data);
