ASP调用WebService转化成JSON数据，附json.min.asp（webservice怎么传递数据）深度揭秘

‘定义soap消息
strxml=”<?xml version=’1.0′ encoding=’utf-8′?>”
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
