人气:0
想了解PHP实现支持GET,POST,Multipart/form-data的HTTP请求类的相关内容吗,在本文为您仔细讲解PHP支持GET,POST,Multipart/form-data的HTTP请求类的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:PHP,HTTP,请求,类,下面大家一起来学习吧。

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

demo示例程序如下:

<?php 
require('HttpRequest.class.php'); 
 
$config = array( 
      'ip' => 'demo.fdipzone.com', // 如空则用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>'; 
 
?>
