上網查了好久的資料
查到有 2 種方式可以達成
1. 使用 XMLHTTP 呼叫
2. 使用 SOAP 呼叫
最後決定用 XMLHTTP 的方式呼叫
因為 SOAP 要另外在 ASP 端安裝 SOAP Toolkit
在這邊記錄一下 XMLHTTP 呼叫 Web Service 的方法
<%
Set objHttp = Server.CreateObject("MSXML2.XMLHTTP")
Set xmlDOC = Server.CreateObject("MSXML.DOMDocument")
' Web Service 網址 (最後面加要呼叫的Function Name)
ws_url = "http://localhost/TestWebService/Service.asmx/Add"
' Web Service 要傳入的參數
ws_params = "Param1=" & 1 & "&Param2=" & 3
' Web Service 的 web.config 要在 <system.web> </system.web> 中設定
' <webservices>
' <protocols>
' <add name="HttpPost"/>
' <add name="HttpGet"/>
' </protocols>
' </webServices>
objHttp.Open "POST", ws_url, False
objHttp.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHttp.Send(ws_params)
xmlDOC.load(objHttp.responseXML)
if objHttp.Status = 200 then
xmlStr = xmlDOC.xml
Response.Write Replace(Replace(xmlStr,"<","<"),">",">")
else
Response.Write "Error : " & objHttp.StatusText & "(" & objHttp.Status & ")"
end if
%>
Set objHttp = Server.CreateObject("MSXML2.XMLHTTP")
Set xmlDOC = Server.CreateObject("MSXML.DOMDocument")
' Web Service 網址 (最後面加要呼叫的Function Name)
ws_url = "http://localhost/TestWebService/Service.asmx/Add"
' Web Service 要傳入的參數
ws_params = "Param1=" & 1 & "&Param2=" & 3

' <webservices>

objHttp.Open "POST", ws_url, False
objHttp.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHttp.Send(ws_params)
xmlDOC.load(objHttp.responseXML)
if objHttp.Status = 200 then
xmlStr = xmlDOC.xml
Response.Write Replace(Replace(xmlStr,"<","<"),">",">")
else
Response.Write "Error : " & objHttp.StatusText & "(" & objHttp.Status & ")"
end if
%>
