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:
- <?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.vevb.com';
- $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。
