ASP中调用方法(SOAP方式)

<%
Dim url,xmlhttp,dom,node,xmlDOC
''''根据webservice的测试页不同的方法构造不同的soap request
SoapRequest = ""& _
""xmlns:xsd="&CHR(34)&"http://www.w3.org/2001/XMLSchema"&CHR(34)&" "& _
"xmlns:soap="&CHR(34)&"http://schemas.xmlsoap.org/soap/envelope/"&CHR(34)&">"& _
""& _
""& _
"311"& _
""& _
""& _
""
url = "http://www.ydcom.net/service/S_COMM.asmx?methodname=GetCZID"
Set xmlDOC =server.CreateObject("MSXML.DOMDocument")
xmlDOC.loadXML(SoapRequest)
Set xmlhttp = server.CreateObject("Msxml2.XMLHTTP")
xmlhttp.Open "POST",url,false
xmlhttp.setRequestHeader "Content-Type", "text/xml;charset=utf-8"
xmlhttp.setRequestHeader "SOAPAction", "http://www.ydcom.net/service/SrvCOMM/S_COMM/GetCZID"
xmlhttp.setRequestHeader "Content-Length",LEN(SoapRequest)
xmlhttp.Send(xmlDOC)

If xmlhttp.Status = 200 Then
xmlDOC.load(xmlhttp.responseXML)
Response.Write xmlhttp.Status&"
"
Response.Write xmlhttp.StatusText&"
执行结果为："
Response.Write xmlDOC.getElementsByTagName("GetCZIDResult")(0).text
else
Response.Write xmlhttp.Status&"
"
Response.Write xmlhttp.StatusText
end if
%>

说明:总的来讲采用webservice的列表页说明来构造不同的SoapRequest,然后,
从返回xmlDoc中取返回值xmlDOC.getElementsByTagName

ASP中调用方法(HTTP方式)

<%
Set objHTTP = Server.CreateObject("MSXML2.XMLHTTP")
Set xmlDOC =Server.CreateObject("MSXML.DOMDocument")
strWebserviceURL = "http://www.ydcom.net/service/S_COMM.asmx/GetCZID"
''''设置参数及其值
strRequest = "sTypeNum=311"
objHTTP.Open "POST", strWebserviceURL, False
''''设置这个Content-Type很重要
objHTTP.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHTTP.SetRequestHeader("Content-Length: 30")
objHTTP.Send(strRequest)
bOK = xmlDOC.load(objHTTP.responseXML)
''''看看状态值
if objHTTP.Status=200 then
xmlStr = xmlDOC.xml
Response.Write xmlStr
else
Response.Write objHTTP.Statu&"
"
Response.Write objHTTP.StatusText
end if

VB.NET中调用方法

1,首先添加web引用,地址为:http://www.ydcom.net/service/s_comm.asmx

2,定义:dim sCom as New net.ydcom.www.S_COMM

3,调用:dim strCZID as string = sComm.GetCZID("313")

long rVal
//string str_endpoint
//str_endpoint = "http://www.ydcom.net/service/s_comm.asmx?WSDL"
conn = create SoapConnection
rVal = Conn.CreateInstance(sCom, "test_wsservice1soap")
sle_1.text = sCom.GetCZID("313"))
destroy conn
