Hello, I would like to suggest 2 patchs. The first is for supporting custom parameters of WMS, I don't know if it's normalize by OGC, but it's supported by Mapserver. For exemple I have this request in openlayers:
http://wmshost/cgi-bin/xyea?LAYERS=oursindep%2Cetablissement&FORMAT=jpg&IDOURSIN=%20uai_dger%7C%7Cinsee_resplegal%20%7C%7Cfiliere_code%7C%7Csecteur_pro_code%7C%7Coption_code&GROUPBYCLAUSE=%20GROUP%20BY%20%20uai_dger&WHERECLAUSE=%20WHERE%20secteur_code%20%3D%201&GEOMSUFFIXE=_rel&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A27572&BBOX=-679807.84,1230100.62,1925309.84,2987770.38&WIDTH=996&HEIGHT=672 And this is the request with my owslib patched : url_wms = 'http://wmshost/cgi-bin/xyea' layers = [ 'oursindep', 'etablissement', 'responsables_legaux', 'regions'] bbox = (-10.900634765625, 36.857250976562, 15.400634765625, 55.742749023437) styles = '' custom = {'WHERECLAUSE':'WHERE secteur_code = 1', 'GROUPBYCLAUSE':'GROUP BY uai_dger', 'IDOURSIN':'uai_dger||insee_resplegal ||filiere_code||secteur_pro_code||option_code'} img = wms.getmap(layers=layers, styles=styles, bbox=bbox, size=(1197, 859), format='image/jpeg', srs='EPSG:4326', custom = custom ) And the second is for solve encoding problem when the return of the wms server is not ascii.
