ASP调用WebService转化成JSON数据，附json.min.asp

首先定义SOAP数据，然后创建HTTP对象，然后使用POST提交，获取状态码为200，就说明调用成功，再进行下一步操作……

'定义soap消息
strxml = "<?xml version='1.0' encoding='utf-8'?>"

strxml = strxml & "</soap:Envelope>"

Set h = createobject( "Microsoft.XMLHTTP")
'向指定的URL发送Post消息

h.setRequestHeader "SOAPAction", "http://tempuri.org/GetCategories"
h.send (strxml)

'显示返回的XML信息

If h.Status = 200 Then
    Set xmlDOC = server.CreateObject("MSXML.DOMDocument")
    xmlDOC.load(h.responseXML)
    jsonText = xmlDOC.childNodes(1).Text 

    '转换成JSON，调用json.min.asp
    Set categories = JSON.parse(jsonText)

    for i = 0 to categories.Length -1
    　　Response.Write(CStr(categories.get(i).CategoryName)) '属性
    　　for j = 0 to categories.get(i).Labels.Length - 1 '集合
       　　Response.Write(CStr(categories.get(i).Labels.get(j).LabelName))
    　　next
    next

    Response.Write h.Status &"&nbsp;"
