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：
rush:PHP;">
_setCookie(substr($line,12)); }
$reHeader .= $line;
if(substr($line,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) < $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/1.1\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,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,$errno,$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,$header);
/*
echo "\r\n";
*/
var_dump($header);
var_dump($data);
希望本文所述对大家的PHP程序设计有所帮助。
