[Pywps-dev] access data WFS and WCS

[Jachym Cepicky]

Hi,

yeah, it was working, I used that several times, BUT

1 - use codified version of the url
2 - omit [] brackets (it should work, but just for the case)
3 - if you are brave enough, try to debug what the problem could be in the
source code level
4 - To me, this is kinnda "adnvanced" request, you should go with POST
request, gives you more save input parsing
5 - Yes, there seems to be bug in execute get parser, the escaped values
are unescaped, attributes of the input parameter are going to look like

 [u'xlink:href=
http://localhost:8080/geoserver/wcs?SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=tiger__demrepro&FORMAT=image/tiff
']

and next statemenet

https://github.com/geopython/pywps/blob/pywps-3.2/pywps/Parser/Execute.py#L593

does not work

2 options:

1 - go with POST request
2 - I've created ticket https://github.com/geopython/pywps/issues/79 hope
to get to it
