Get Image using owslib

Rate this Message:
Hi,
I just tried getting an image from a WMS server using owslib. It seems that line 227 in wms is missing '?' between the base_url and the parameter string (data) because in the examples found in the owslib website, the base_url does not contain the '?'. /usr/lib/python2.5/site-packages/OWSLib-0.3.1-py2.5.egg/owslib/wms.py 227: u = self._open(base_url + data) changing to: u = self._open(base_url + '?' + data) solves the problem. Is this a bug or should I add the '?' to the base_url? Thanks in advance! -- Manel Clos _______________________________________________ Community mailing list Community@... http://lists.gispython.org/mailman/listinfo/community |

Hi Manel
This is probably a bug. There's now a more robust method in the utils package that should be used instead of self._open. I'll try and update the wms code when I get a chance (unless anyone else does first). Could you send me the WMS url please so I can test against it?

Hi Dominic,
The WMS server is internal. I was getting a 500 error from the server, so I printed the resulting url in wms.py and it was obvious that the '?' was missing. That solved the problem. I can test any new version or code if needed. Thanks! -----Mensaje original----- De: community-bounces@...

Hi Manel,
Okay thanks - it is still a problem though as it should use the method from the utils module (which allows with or without a "?") I just looked at the WMS code though and it's not as straightforward as replacing the opening method - I'd forgotten the wms module has some extra code to handle HTTP password authorization when opening urls. So this should probably also be moved into the openURL method in the utils package (which also solves the "?" problem). Thanks for bringing it to our attention - I'll make a ticket for this issue.
