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

(编辑:jimmy 日期: 2024/11/27 浏览:3 次 )

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……

看一下具体实现的代码吧

<!--#Include virtual="/Include/json.min.asp"-->
<%
Dim strxml
Dim str

'定义soap消息
strxml = "<"
strxml = strxml & "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>"       
strxml = strxml & "<soap:Body> "
strxml = strxml & "<GetCategories xmlns='http://tempuri.org/'>"
strxml = strxml & "<reqcode>30000001</reqcode>" '参数1
strxml = strxml & "<sign>ssssss</sign>" '参数2
strxml = strxml & "</GetCategories>"
strxml = strxml & "</soap:Body>"
strxml = strxml & "</soap:Envelope>"

Set h = createobject( "Microsoft.XMLHTTP")
'向指定的URL发送Post消息
h.open "POST", "http://www.domain.com/WebService.asmx", False
h.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
h.setRequestHeader "Content-Length",LEN(strxml)
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
  <pre name="code" class="vb"><script language="javascript" runat="Server">
if(!Array.prototype.get){Array.prototype.get=function(prop){return this[prop];}}"use strict";if(!this.JSON){JSON={};}

附:json.min.asp
