Hello All,
I am trying to use jQuery .ajax to POST requests to Geoserver for dynamically
creating featuretypes and amending them. I am using a proxy python script to
get round cross-domain issues. The request always comes back with an error
code of 500. I can run GET requests with no errors using the same proxy.
Can anyone see what is going wrong or offer assistance? Thanks.
My request looks like this:
var proxyurl = 'http://localhost/proxy.py?url=';
var lyrname = "subproject11_inputs";
$.ajax({
type: "POST",
url: proxyurl +
"http://localhost:8080/geoserver/rest/workspaces/jflow/datastores/jflow_testdb_v46/featuretypes.xml";,
data: '<featureType><name>' + lyrname + '</name></featureType>',
username: "admin",
password: "geoserver",
contentType: "application/xml", //; charset=utf-8 -not needed
complete: function(xReq,txtStatus) {
alert('in complete: xReq.status=' + xReq.status + ' txtstatus=' + txtStatus +
'; responseText= ' + xReq.responseText);
}
}); // end of $.ajax
My proxy script looks like this:
'''#!C:/Python26 python'''
#!/usr/bin/env python
import urllib2
import cgi
import sys, os
default_url = 'http://www.bbc.co.uk'
# Designed to prevent Open Proxy type stuff. Add site domains, minus the
http:// prefix/part.
allowedHosts = ['ncl.ac.uk', 'localhost:8080',
'www.bbc.co.uk',

method = os.environ['REQUEST_METHOD']
if method == 'POST':
qs = os.environ['QUERY_STRING']
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
try:
host = url.split('/')[2]
if allowedHosts and not host in allowedHosts:
print 'Status: 502 Bad Gateway'
print 'Content-Type: text/plain'
print
print 'This proxy does not allow you to access that location (%s).' %
(host,)
print
print os.environ
elif url.startswith('http://') or url.startswith('https://'):
if method == 'POST':
length = int(os.environ['CONTENT_LENGTH'])
headers = {'Content-Type': os.environ['CONTENT_TYPE']}
body = sys.stdin.read(length)
r = urllib2.Request(url, body, headers)
y = urllib2.urlopen(r)
else:
y = urllib2.urlopen(url)
# print content type header
i = y.info()
if i.has_key('Content-Type'):
print 'Content-Type: %s' % (i['Content-Type'])
else:
print 'Content-Type: text/plain'
print
print y.read()
y.close()
else:
print 'Content-Type: text/plain'
print
print 'Illegal request.'
except Exception, E:
print 'Status: 500 Unexpected Error'
print 'Content-Type: text/plain'
print
print 'Some unexpected error occurred. Error text was:', E
Thanks for any assistance.
