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:


<?php
class ZSocket {
 /*
 * Init 
 */
 private function _fsockopen($host, $port, &$errno, &$errstr, $timeout){
 $ip = @gethostbyname($host);
 $s = @socket_create(AF_INET, SOCK_STREAM, 0);
 if(socket_set_nonblock($s)){
 $r = @socket_connect($s, $ip, $port);
 if ($r || socket_last_error() == EINPROGRESS) {
 $errno = EINPROGRESS;
 return $s;
 }
 }
 $errno = socket_last_error($s);
 $errstr = socket_strerror($errno);
 socket_close($s);
 return false;
 }
 /*
 * 设置Cookie
 */
 private function _setCookie($cookie){
 $_cookies = explode("; ",$cookie);
 $_tmp = explode("=",$_cookies[0]);
 setcookie($_tmp[0], $_tmp[1]);
 return $_cookies;
 }
 /*
 * 获取返回数据header内容
 */
 private function _getDataHeader(&$fp,&$reHeader,&$cookies){
 $maxlen = 0;
 while(!feof($fp)){
 $line = fgets($fp,1024);
 if(substr($line, 0, 12) == 'Set-Cookie: '){ $cookies[] = $this->_setCookie(substr($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) < $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, 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 = '/';
$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";
print_r($header);
print_r($data);
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。
