First, send the request and then process the response. I directly access the WebService written in. net. Click the method name to view the instance.CodeIn ASP, you only need to use Microsoft. XMLHTTP to send a request, and then process the XML results.
Note that the namespace cannot be written incorrectly.

I. SOAP request example
The following is a SOAP request example. The displayed placeholder must be replaced by the actual value.
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"
string
string
to interact With WebService, You need to construct a SOAP request identical to the preceding one:
<%
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" 'must be the same as the WebService namespace, otherwise the service will reject
XMLHTTP. send (soapr Equest)
'. In this way, XMLHTTP is used to successfully send a SOAP request that matches the soap sample.
'check whether the response is successful:
response. write XMLHTTP. status & "& nbsp;"
response. write XMLHTTP. statustext
set XMLHTTP = nothing
%>
If the call succeeds, 200 OK is displayed. If the call fails, 500 internal server error is displayed? Connection: keep-alive.
after successful connection, you can use the WebService response as follows:
soap response example
below is a soap response example. The displayed placeholder must be replaced by the actual value.
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 = "The http://www.w3.org/2001/xmlschema-instance" xmlns: XSD = "The http://www.w3.org/2001/xmlschema" xmlns: Soap = "The http://schemas.xmlsoap.org/soap/envelope/">
<Soap: Body>
<Loginbyaccountresponse xmlns = "http://tempuri.org/">
<Loginbyaccountresult> string </loginbyaccountresult>
</Loginbyaccountresponse>
</Soap: Body>
</Soap: envelope>
This is the soap response example corresponding to the SOAP request example. After the request is successfully sent, you can view the response:
If xml http. 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 ;"
