PHP实现支持GET,POST,Multipart/form-data的HTTP请求类,multipartform-data

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:

<&#63;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:

<&#63;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 class="brush:php;toolbar:false">'; 
print_r($result); 
echo '

希望本文所述对大家的PHP程序设计有所帮助。

【急】对于PHP中文件上传 POST传值问题 不确定是enctype="multipart/form-data"属性问题还是版本问题

文件上传类型为file的控件,后台获取时只能用$_FILES来获取,其他的控件类型才是用$_POST来获取,你只需要用$_FILES获取的值来进行你的处理。
 

js 模拟POST提交enctype="multipart/form-data"类型的表单

只是需要文件上传才用它的
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded;");
改成
xmlHttp.setRequestHeader("Content-Type","multipart/form-data;");

至于发送二进制数据,你自己解决吧。
-----------------------------7db8c30150364 这个其实有规律的
就是一个开始段一个结束段,7db8c30150364 只是用一串不重复的字符,标识一起其中间的东西就是数据,Content-Disposition: form-data; name="polls[]" 这个是用来表示什么数据,文件名是啥。

其实在socket发包中,上传文件的时候就要这么用,有空研究一下HTTP里面POST 文件时,应该如何处理。
