Re: Howto question - SOAP on the command line

From: Dan White <ygor_at_comcast.net>

Thanks for the response.

Here's some more detail:
This service returns television schedule and program listings in an XML
statement

The wget statement is this:
==========================
wget --debug --http-user='userid' --http-passwd='yourPassword'
--post-file='soap.xml' --header='Accept-Encoding:gzip'
http://datadirect.webservices.zap2it.com/tvlistings/xtvdService
--output-document=tv.gz
==========================
and the soap.xml file contains:
==========================
<?xml version='1.0' encoding='utf-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:SOAP-ENC='http://schemas.xmlsoap.org/soap/encoding/'>
        <SOAP-ENV:Body>
                <ns1:download xmlns:ns1='urn:TMSWebServices'>
                        <startTime xsi:type='xsd:dateTime'>2005-04-20T00:00:00</startTime>
                        <endTime xsi:type='xsd:dateTime'>2005-04-20T00:06:00</endTime>
                </ns1:download>
        </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
==========================
OK so far ?

Now, if I run the wget with full debug and other junk turned on, I get
this:
==========================
wget --debug --server-response --http-user='userid'
--http-passwd='password' --post-file='soap.xml'
--header='Accept-Encoding:gzip'
http://datadirect.webservices.zap2it.com/tvlistings/xtvdService

...and all that is in the curl output is
<HTML><HEAD><TITLE>401 Unauthorized</TITLE></HEAD><BODY><H1>401
Unauthorized</H1></BODY></HTML>

Now, what I see happening is wget receives the first response ("401
Unauthorized")
then it closes the socket, re-opens it, and THEN it get the XML.

I see curl bagging it after the first response ("401 Unauthorized") and
not picking up the XML which is sent next.

I can find nothing in the curl documentation to help out.

Does this help ?
