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.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 $_filedata = array(); // 设置连接参数 public function setConfig($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 = $this->_url.'?'.http_build_query($this->_formdata); $out = "GET ".$url." http/1.1\r\n"; $out .= "host: ".$this->_host."\r\n"; $out .= "connection: close\r\n\r\n"; return $out; } // post 方式,处理发送的数据 private function sendPost(){ // 检查是否空数据 if(!$this->_formdata && !$this->_filedata){ return false; } // form data $data = $this->_formdata? $this->_formdata : array(); // file data if($this->_filedata){ foreach($this->_filedata as $filedata){ if(file_exists($filedata['path'])){ $data[$filedata['name']] = file_get_contents($filedata['path']); } } } if(!$data){ return false; } $data = http_build_query($data); $out = "POST ".$this->_url." http/1.1\r\n"; $out .= "host: ".$this->_host."\r\n"; $out .= "content-type: application/x-', 'port' => 80, 'errno' => '', 'errstr' => '', 'timeout' => 30, 'url' => '/getapi.php', //'url' => '/postapi.php', //'url' => '/multipart.php' ); $formdata = array( 'name' => 'fdipzone', 'gender' => 'man' ); $filedata = array( array( 'name' => 'photo', 'filename' => 'photo.jpg', 'path' => 'photo.jpg' ) ); $obj = new HttpRequest(); $obj->setConfig($config); $obj->setFormData($formdata); $obj->setFileData($filedata); $result = $obj->send('get'); //$result = $obj->send('post'); //$result = $obj->send('multipart'); echo '<pre>'; print_r($result); echo '</pre>'; ?>
