本文实例讲述了PHP实现支持GET,POST,Multipart/form-data的HTTP请求类及其应用，分享给大家供大家参考。具体如下：HttpRequest.html' target='_blank'>class.php类文件如下： php /** HttpRequest class, HTTP请求类，支持GET,POST,Multipart/form-data * Date: 2013-09-25 * Author: fdipzone * Ver: 1.0 * Func: * public setConfig 设置连接参数 * public setFormdata 设置表单数据 * public setFiledata 设置文件数据 * public send 发送数据 * private connect 创建连接 * private disconnect 断开连接 * private sendGet get 方式,处理发送的数据,不会处理文件数据 * private sendPost post 方式,处理发送的数据 * private sendMultipart multipart 方式,处理发送的数据,发送文件推荐使用此方式 class HttpRequest{ // class start private $_ip = ''; private $_host = ''; private $_url = ''; private $_port = ''; private $_errno = ''; private $_errstr = ''; private $_timeout = 15; private $_fp = null; private $_formdata = array(); private $_filedata = array();
public function setConfig($config){ $this- _ip = isset($config['ip']) $config['ip'] : ''; $this- _host = isset($config['host']) $config['host'] : ''; $this- _url = isset($config['url']) $config['url'] : ''; $this- _port = isset($config['port']) $config['port'] : ''; $this- _errno = isset($config['errno']) $config['errno'] : ''; $this- _errstr = isset($config['errstr']) $config['errstr'] : ''; $this- _timeout = isset($confg['timeout']) $confg['timeout'] : 15; // 如没有设置ip，则用host代替 if($this- _ip==''){ $this- _ip = $this- _host; // 设置表单数据 public function setFormData($formdata=array()){ $this- _formdata = $formdata; // 设置文件数据 public function setFileData($filedata=array()){ $this- _filedata = $filedata; // 发送数据 public function send($type='get'){ $type = strtolower($type); // 检查发送类型 if(!in_array($type, array('get','post','multipart'))){ return false; // 检查连接 if($this- connect()){ switch($type){ case 'get': $out = $this- sendGet(); break; case 'post': $out = $this- sendPost(); break; case 'multipart': $out = $this- sendMultipart(); break; // 空数据 if(!$out){ return false; // 发送数据 fputs($this- _fp, $out); // 读取返回数据 $response = ''; while($row = fread($this- _fp, 4096)){ $response .= $row; // 断开连接 $this- disconnect(); $pos = strpos($response, "/r/n/r/n"); $response = substr($response, $pos+4); return $response; }else{ return false; // 创建连接 private function connect(){ $this- _fp = fsockopen($this- _ip, $this- _port, $this- _errno, $this- _errstr, $this- _timeout); if(!$this- _fp){ return false; return true; // 断开连接 private function disconnect(){ if($this- _fp!=null){ fclose($this- _fp); $this- _fp = null; // get 方式,处理发送的数据,不会处理文件数据 private function sendGet(){ // 检查是否空数据 if(!$this- _formdata){ return false; // 处理url $url = $this- _url.'
