[Users] WMSCapabilitiesStore URL problem

[Anne Brookes]

Hello Hugo,
I had the same problem and found that amending the proxy.cgi, where it handles the url= part of the querystring, solved the problem.
This is the new bit of the proxy.cgi:
method = os.environ['REQUEST_METHOD']
qs = os.environ['QUERY_STRING']
if (method == 'POST') or (method == 'PUT'):
    d = cgi.parse_qs(qs)
    if d.has_key('url'):
        url = d['url'][0]
    else:
        url = default_url
else:
    #fs = cgi.FieldStorage()
    #url = fs.getvalue('url', default_url) # get url to proxy to from request URL, or use default
    url = qs[4:]  #fetch from query string minus first 'url='

I have commented out the original fs = cgi.FieldStorage() and url = fs.getvalue('url', default_url) lines and replaced with  url = qs[4:]  (and added qs = os.environ['QUERY_STRING'] at the top.  This seemed to be a more robust way of slicing the url string from the original querystring than getting it from the FieldStorage object.

I hope this works for you too.
Cheers,

Subject: [Users] WMSCapabilitiesStore URL problem

Hello all,

I'm having troubles to populate the WMSCapabilitiesStore. I have the following code:

var wmsStore = new GeoExt.data.WMSCapabilitiesStore({
   url: 'http://localhost:8080/geoserver/ows?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.1.1',
   autoLoad: true
});

The request is never shown in firebug. I know this might be related with the proxy definition but i'm sure i have configured the openlayers proxy.cgi correctly once that i'm able to correctly load WFS coming from this very same Geoserver. Also, when using the following address (directly on the browser) the response is returned correctly:

http://localhost/cgi-bin/proxy.cgi?url=http://localhost:8080/geoserver/ows?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.1.1'

However if i try to use this url for the store i get the following error:

 <ServiceException code="MissingParameterValue" locator="request">
      Could not determine geoserver request from http request org.apache.catalina.connector.RequestFacade



I think this is related with wrong parameter passing to the server because, if i check the request params in firebug i can see the following:
REQUEST

GetCapabilities

VERSION

1.1.1

url

http://localhost:8080/geoserver/ows?SERVICE=WMS



I have also tried with the following code:

var wmsStore = new GeoExt.data.WMSCapabilitiesStore({
  proxy: new Ext.data.ScriptTagProxy({
      url: 'http://localhost:8080/geoserver/ows?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.1.1',
   }),
   autoLoad: true
});

With this approach i get an error related to the reader (i suppose) like the following:
missing ; before statement
[cid:~WRD000.jpg]<!DOCTYPE WMT_MS_Capabilities SYSTEM "...s/wms/1.1.1/WMS_MS_Capabilities.dtd">

So, finally my question: what am i doing wrong here? Or do i need to configure something else?

Thanks in advance.
Kind regards,

Hugo
