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

  • 可以说我没有class file目标服务器。这就是为什么我想通过cURL.

现在我的班级样本是：

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

并且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);

..但是该类不能在目标端使用，这里是receiver.php（在另一个没有类文件的不同服务器上）：

$myClass = unserialize($_POST['theclass']);
echo $myClass->sayHello();
  • 请问有什么好主意吗？
  • 它甚至耐用吗？

1）使用http_build_query ()：

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

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

您可以使用此类快速入门
