本文實例講述了php實現(xiàn)支持GET,POST,Multipart/form-data的HTTP請求類及其應(yīng)用，分享給大家供大家參考。具體如下：
HttpRequest.class.php類文件如下：
<?php /** HttpRequest class, HTTP請求類，支持GET,POST,Multipart/form-data * Date: 2013-09-25 * Author: fdipzone * Ver: 1.0 * * Func: * public setConfig 設(shè)置連接參數(shù) * public setFormdata 設(shè)置表單數(shù)據(jù) * public setFiledata 設(shè)置文件數(shù)據(jù) * public send 發(fā)送數(shù)據(jù) * private connect 創(chuàng)建連接 * private disconnect 斷開連接 * private sendGet get 方式,處理發(fā)送的數(shù)據(jù),不會處理文件數(shù)據(jù) * private sendPost post 方式,處理發(fā)送的數(shù)據(jù) * private sendMultipart multipart 方式,處理發(fā)送的數(shù)據(jù),發(fā)送文件推薦使用此方式 */ 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 $_filedata = array(); // 設(shè)置連接參數(shù) public function setConfig($config){ $this->_ip = isset($config['ip'])?

demo示例程序如下：
<?php require('HttpRequest.class.php'); $config = array( 'ip' => 'demo.fdipzone.com', // 如空則用host代替 'host' => 'demo.fdipzone.com', '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>'; ?>
