Hello,
I recently started using GeoExt2. With OpenLayers, I was using this
version of proxy.cgi :
http://trac.osgeo.org/openlayers/browser/trunk/openlayers/examples/proxy.cgi.
With GeoExt2, I encountered problems to run a WMS GetCapabilities. I
solved it by modifying the proxy.cgi like in this post :
http://www.geoext.org/pipermail/users/2011-May/002287.html.
But with this new version of proxy.cgi, the WMSGetFeatureInfo query
fails with the error 500 'Some unexpected error occurred. Error text
was: list index out of range'.
Actually the queried URL is URL encoded :
http://localhost/cgi-bin/proxy.cgi?url=http%3A%2F%2F162.38.140.226%3A8080%2Fgeoserver%2Fsf%2Fwms%3FSERVICE%3DWMS%26LAYERS%3Dsf%253Aborehole%26QUERY_LAYERS%3Dsf%253Aborehole%26STYLES%3D%26SERVICE%3DWMS%26VERSION%3D1.1.1%26REQUEST%3DGetFeatureInfo%26EXCEPTIONS%3Dapplication%252Fvnd.ogc.se_inimage%26BBOX%3D-5315418.716245%252C4750095.377026%252C5916543.966529%252C7166728.462954%26FEATURE_COUNT%3D10%26HEIGHT%3D247%26WIDTH%3D1148%26FORMAT%3Dimage%252Fpng%26INFO_FORMAT%3Dapplication%252Fvnd.ogc.gml%26SRS%3DEPSG%253A900913%26X%3D603%26Y%3D127,
.. while the same URL without encoding succeeds:
|http://localhost/cgi-bin/proxy.cgi?url=http://162.38.140.226:8080/geoserver/sf/wms?SERVICE=WMS&LAYERS=sf%3Aborehole&QUERY_LAYERS=sf%3Aborehole||&STYLES=&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&EXCEPTIONS=application%2Fvnd.ogc.se_inimage||&BBOX=-5315418.716245%2C4750095.377026%2C5916543.966529%2C7166728.462954&FEATURE_COUNT=10&HEIGHT=247||&WIDTH=1148&FORMAT=image%2Fpng&INFO_FORMAT=application%2Fvnd.ogc.gml&SRS=EPSG%3A900913&X=603&Y=127|
If I go back to the original version of proxy.cgi, the
WMSGetFeatureInfo query succeeds, and the WMS GetCapabilities fails.
Here is the beginning of my proxy.cgi file, with lines that allow WMS
GetCapabilities query to work but prevent WMSGetFeatureInfo query from
working:
/#!/usr/bin/env python//
//
//import urllib2//
//import cgi//
//import sys, os//
//
//# Designed to prevent Open Proxy type stuff.//

//
//method = os.environ["REQUEST_METHOD"]//
//qs = os.environ['QUERY_STRING']////# Added to solve problem with
geoext and WMSgetCapabilities//
//
if method == "POST":
qs = os.environ["QUERY_STRING"]
d = cgi.parse_qs(qs)
if d.has_key("url"):
url = d["url"][0]
else:
url = "http://www.openlayers.org";
else:
fs = cgi.FieldStorage()
#url = fs.getvalue('url', "http://www.openlayers.org";) //# Removed
to solve problem with geoext and WMSgetCapabilities//
//url = qs[4:] //# Added to solve problem with geoext and
WMSgetCapabilities/
Would you have any idea to solve this?
Thanks,
Juliette
