本文提供了一个使用 ASP 发送 HTTP 请求（GET 和 POST）的示例，并演示了如何使用 JSON 格式传输数据。示例包括创建请求、设置头部信息及处理响应。

<% Response.CodePage=65001%> 
<% Response.Charset="UTF-8" %>

  <body>

<script language="JScript" runat="Server">
	function toObject(json) {
		eval("var o=" + json);

<!-- #include file="json.asp" -->

		Set http = Server.createobject("Microsoft.XMLHTTP")

提供一个测试asp发送http request(get/post),并且可以将数据发送并接收的例子。传输的数据格式使用json。附件中有完整代码。
