ebay Developer 之基础SOAP协议

在使用运用ebay 提供的各种各样的Call之前，必须要明白其call是怎么来获取到信息的。
正如我们在浏览器上输入：http://www.google.com一样能够找到google页面并且通过google检索到你要的信息。以上这个在浏览器上输入http，就是要符合http协议。只有你符合了http协议那么就能够按照该协议正确的得到你想要的信息。而ebay 中的call则是符合SOAP协议。该协议就是保证了信息的发送和接收的正确性。
  什么是SOAP？
    SOAP简单说就是（Simple Object Access Protocol ）简单对象访问协议是在分散或分布式的环境中交换信息的简单的协议。该协议是一个基于XML的协议，它包括四个部分：SOAP封装(envelop)，封装定义了一个描述消息中的内容是什么，是谁发送的，谁应当接受并处理它以及如何处理它们的框架；SOAP编码规则（encoding rules），用于表示应用程序需要使用的数据类型的实例; SOAP RPC表示(RPC representation)，表示远程过程调用和应答的协定;SOAP绑定（binding），使用底层协议交换信息。

  在ebay中你可以通过使用任何call的call.getResponseXML()来查看。熟悉是ebay Developer的基础。
其实就是在与将SOAP解析成多个Object
例如： 看看GetItem Call 的Response

<?xml version="1.0" encoding="utf-8"?>
