oostethys_sos.cgi and POST requests?

[Emilio Mayorga]

Hi Eric,

Rick Blair is enhancing ERDDAP to make it play nicer with SOS
services. We've run into a problem with your Perl OOSTethys SOS server
(as implemented and slightly modified by myself, on my Xenia-based
NANOOS database). I've never had any problems with normal HTTP GET
requests. Have you, Jeremy here, or anyone you know exercised the POST
request parts of this code, much at all?

When Rick issues a POST request from ERDDAP (Java), using the
following payload string (the string is formatted to pretty print, but
that should be irrelevant):
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +    "<GetObservation
\n" +    "xmlns=\"http://www.opengis.net/sos/1.0\"\n" +
"xmlns:gml=\"http://www.opengis.net/gml\"\n" +
"xmlns:ogc=\"http://www.opengis.net/ogc\"\n" +
"xmlns:ows=\"http://www.opengeospatial.net/ows\"\n" +
"xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"\n" +
"xmlns:swe=\"http://www.opengis.net/swe\"\n" +    "service=\"SOS\"
version=\"1.0.0\" >\n" +    "<offering>uw.orca.duckab.vpb</offering>"
+        "<observedProperty>water_temperature</observedProperty>" +
"<eventTime>\n" +      "<ogc:T_During>\n" +
"<gml:TimePeriod>\n" +
"<gml:beginPosition>2008-12-28T00:00:00</gml:beginPosition>\n" +
   "<gml:endPosition>2008-12-29T04:40:31</gml:endPosition>\n" +
"</gml:TimePeriod>\n" +      "</ogc:T_During>\n" +    "</eventTime>\n"
+    "<resultFormat>application/com-xml</resultFormat>\n" +
"</GetObservation>\n";

We get this error back:
<?xml version="1.0"?> <ExceptionReport
xmlns="http://www.opengis.net/ows"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.opengis.net/ows owsExceptionReport.xsd"
version="1.0.0" language="en"> <Exception locator="service"
exceptionCode="NoApplicableCode"><ExceptionText>Data not available for
the requested Time or BBOX.</ExceptionText></Exception>
</ExceptionReport>

The equivalent GET request works without any issues:
http://habu.apl.washington.edu/cgi-bin/xan_oostethys_sos.cgi?request=GetObservation&offering=uw.orca.duckab.vpb&observedProperty=water_temperature&eventTime=2008-12-28T00:00:00/2008-12-29T04:40:31

BTW, this URL is now externally accessible, though it's not
operational/QA-QC'd yet. You can try it out, though it's not terribly
interesting or enlightening.

Thanks for your help, as always! Cheers,

Rick,

Excellent!! Very good eye, esp. given that EVENTTIME is actually used
just once elsewhere in the code, in sub doGetObservation:
my $in_time = $in_params->{EVENTTIME};

I'm cc'ing this to Eric and the Xenia list, as a wrap-up and
resolution of our question.

Yes Rick,
Excellent! I will update the PERL code via svn in Google code.
