一．SOAP请求示例
下面是一个 SOAP 请求示例。所显示的占位符需要由实际值替换。
POST /WebService1/UserSignOn.asmx HTTP/1.1
Host: 192.100.100.81
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://tempuri.org/LoginByAccount"

<?xml version="1.0" encoding="utf-8"?
<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/"
  <soap:Body
    <LoginByAccount xmlns="http://tempuri.org/"
      <usernamestring</username
      <passwordstring</password
    </LoginByAccount
  </soap:Body
</soap:Envelope
为了与WEBSERVICE交互，需要构造一个与上完全相同的SOAP请求：
<%
url = "http://192.100.100.81/WebService1/UserSignOn.asmx"

SoapRequest="<?xml version="&CHR(34)&"1.0"&CHR(34)&" encoding="&CHR(34)&"utf-8"&CHR(34)&"?"& _
"<soap:Envelope xmlns:xsi="&CHR(34)&"http://www.w3.org/2001/XMLSchema-instance"&CHR(34)&" "& _
"xmlns:xsd="&CHR(34)&"http://www.w3.org/2001/XMLSchema"&CHR(34)&" "& _
"xmlns:soap="&CHR(34)&"http://schemas.xmlsoap.org/soap/envelope/"&CHR(34)&""& _
"<soap:Body"& _

"<LoginByAccount xmlns="&CHR(34)&"http://tempuri.org/"&CHR(34)&""& _
"<username"&username&"</username"& _
"<password"&password&"</password"& _
"</LoginByAccount"& _

"</soap:Body"& _
"</soap:Envelope"

Set xmlhttp = server.CreateObject("Msxml2.XMLHTTP")
xmlhttp.Open "POST",url,false
xmlhttp.setRequestHeader "Content-Type", "text/xml;charset=utf-8"
xmlhttp.setRequestHeader "HOST","192.100.100.81"
xmlhttp.setRequestHeader "Content-Length",LEN(SoapRequest)
xmlhttp.setRequestHeader "SOAPAction", "http://tempuri.org/LoginByAccount" ‘一定要与WEBSERVICE的命名空间相同，否则服务会拒绝
xmlhttp.Send(SoapRequest)
‘这样就利用XMLHTTP成功发送了与SOAP示例所符的SOAP请求.
‘检测一下是否成功：
Response.Write xmlhttp.Status&”&nbsp;”
Response.Write xmlhttp.StatusText
Set xmlhttp = Nothing
%
如果成功会显示200 ok,不成功会显示 500 内部服务器错误〿 Connection: keep-alive .
成功后就可以利用WEBSERVICE的响应，如下：
SOAP响应示例
下面是一个 SOAP 响应示例。所显示的占位符需要由实际值替换。
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?
<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/"
  <soap:Body
    <LoginByAccountResponse xmlns="http://tempuri.org/"
      <LoginByAccountResultstring</LoginByAccountResult
    </LoginByAccountResponse
  </soap:Body
</soap:Envelope
这是与刚才SOAP请求示例所对应的SOAP响应示例,在成功发送请求后，就可以查看该响应 ：
If xmlhttp.Status = 200 Then

Set xmlDOC =server.CreateObject("MSXML.DOMDocument")
xmlDOC.load(xmlhttp.responseXML)
xmlStr = xmlDOC.xml
Set xmlDOC=nothing
xmlStr = Replace(xmlStr,"<","&lt;")
xmlStr = Replace(xmlStr,"","&gt;")
Response.write xmlStr
Else

Response.Write xmlhttp.Status&"&nbsp;"
Response.Write xmlhttp.StatusText

End if
请求正确则给出完整响应，请求不正确（如账号，密码不对）响应的内容就会信息不完整.
取出响应里的数据，如下：
If xmlhttp.Status = 200 Then

Set xmlDOC = server.CreateObject("MSX
