Question

在PHP + cURL中，我可以传递简单的objects，如JSON / Array Objects，但仍然不知道如何传递整个class对象。

假设我在目标服务器上没有class file。这就是为什么我想通过cURL转发。

现在我的班级样本是：

class MyClass {
    function sayHello() {
        return "Hello world!";
    }
}

sender.php（在一台服务器上）：

require_once("class.myclass.php");
$myClass = new MyClass;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://................");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('theclass' => serialize($myClass), 'username' => "abc123"));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER , 1);
echo $response = curl_exec($ch);
curl_close($ch);

..但是这个类不能在目的端使用，这里是receiver.php（在那里没有类文件的另一台服务器上）：

$myClass = unserialize($_POST['theclass']);
echo $myClass->sayHello();

有什么好主意吗？
它是否持久耐用？

Answer 1

1）使用http_build_query（）：

$postdata = array('theclass' => serialize($myClass), 'username' => "abc123");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postdata) );

2）将require_once("class.myclass.php");添加到receiver.php

您可以使用此类进行快速输入

<?php 
class cURL { 
var $headers; 
var $user_agent; 
var $compression; 
var $cookie_file; 
var $proxy; 
function cURL($cookies=TRUE,$cookie='cookies.txt',$compression='gzip',$proxy='') { 
    $this->headers[] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg'; 
    $this->headers[] = 'Connection: Keep-Alive'; 
    $this->headers[] = 'Content-type: application/x-www-form-urlencoded;charset=UTF-8'; 
    $this->user_agent = 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR       1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)'; 
    $this->compression=$compression; 
    $this->proxy=$proxy; 
    $this->cookies=$cookies; 
    if ($this->cookies == TRUE) $this->cookie($cookie); 
} 
function cookie($cookie_file) { 
    if (file_exists($cookie_file)) { 
    $this->cookie_file=$cookie_file; 
} else { 
    fopen($cookie_file,'w') or $this->error('The cookie file could not be opened. Make   sure this directory has the correct permissions'); 
   $this->cookie_file=$cookie_file; 
   fclose($this->cookie_file); 
    } 
} 
function get($url) { 
    $process = curl_init($url); 
   curl_setopt($process, CURLOPT_HTTPHEADER, $this->headers); 
   curl_setopt($process, CURLOPT_HEADER, 0); 
   curl_setopt($process, CURLOPT_USERAGENT, $this->user_agent); 
   if ($this->cookies == TRUE) curl_setopt($process, CURLOPT_COOKIEFILE, $this- >cookie_file); 
   if ($this->cookies == TRUE) curl_setopt($process, CURLOPT_COOKIEJAR, $this->cookie_file); 
    curl_setopt($process,CURLOPT_ENCODING , $this->compression); 
    curl_setopt($process, CURLOPT_TIMEOUT, 30); 
   if ($this->proxy) curl_setopt($process, CURLOPT_PROXY, $this->proxy); 
        curl_setopt($process, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1); 
        $return = curl_exec($process); 
        curl_close($process); 
     return $return;

    $process = curl_init($url); 
     curl_setopt($process, CURLOPT_HTTPHEADER, $this->headers); 
      curl_setopt($process, CURLOPT_HEADER, 1); 
      curl_setopt($process, CURLOPT_USERAGENT, $this->user_agent); 
     if ($this->cookies == TRUE) curl_setopt($process, CURLOPT_COOKIEFILE, $this- >cookie_file); 
      if ($this->cookies == TRUE) curl_setopt($process, CURLOPT_COOKIEJAR, $this->cookie_file); 
      curl_setopt($process, CURLOPT_ENCODING , $this->compression); 
       curl_setopt($process, CURLOPT_TIMEOUT, 30); 
   if ($this->proxy) curl_setopt($process, CURLOPT_PROXY, $this->proxy); 
         curl_setopt($process, CURLOPT_POSTFIELDS, $data); 
        curl_setopt($process, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1); 
         curl_setopt($process, CURLOPT_POST, 1); 
      $return = curl_exec($process); 
   curl_close($process); 
    return $return; 
} 
    function error($error) { 
             echo "<center><div style='width:500px;border: 3px solid #FFEEFF; padding:                 3px; background-color: #FFDDFF;font-family: verdana; font-size: 10px'><b>cURL Error</b>     <br>$error</div></center>"; 
              die; 
      } 
  } 
    $cc = new cURL(); 
    $cc->get('http://www.example.com'); 
   $cc->post('http://www.example.com','foo=bar'); 
    ?>

PHP cURL传递整个“类对象”？
