I was wondering how to make a GET request to geoserver 2.6 in Python.

import urllib2, json
url = 'http://localhost:8080/geoserver/rest/workspaces.json'  
authKey = 'admin:geoserver'
headers ={'Authorization': "Basic " + authKey}
params = {}
request = urllib2.Request(url, json.dumps(params), headers)

try:
    response = urllib2.urlopen(request, timeout=30).read()
    print json.loads(response)
except urllib2.HTTPError as e:
    print e
    print e.header
    print e.read()

with code above, I get HTTP Error 500: Server Error. If I set the value of authKey to '', then I get "HTTP Error 401: Full authentication is required to access this resource"

So how can I set up the request header with authorization?


Update:
I print e.headers in the exception, then I got:

Date: Tue, 17 Mar 2015 15:33:04 GMT
Content-Type: text/html;charset=ISO-8859-1

  • not really. I have updated the header information when exception happens. – stevenhz Mar 17 '15 at 15:39
  • What does e.read() return? Perhaps the contents of the HTTPError provide some details. – Richard Morgan Mar 17 '15 at 16:18
  • e.read() returns: "Could not determine format. Try setting the Content-type header.". Then I specify the the 'Content-type':'application.json' in the headers variable, the 'print e' returns "HTTP Error 500: Server error". And 'print e.read()' returns nothing. Geoserver document says error 500 often donates a syntax error in the request. – stevenhz Mar 18 '15 at 21:05

I have a REST example that works on GWC, so I'll set it up so it's shared: https://gist.github.com/alexgleith/c39c3f520102c30e4dec

Here's the meaty bits:

url = baseURL + layer + '.json'
request = urllib2.Request(url)
base64string = base64.encodestring('%s:%s' % (un, pw)).replace('\n', '')
request.add_header("Authorization", "Basic %s" % base64string)
request.add_header('Content-Type', 'application/json')
data = {'seedRequest':{'minX':[],'minY':[],'maxX':[],'maxY':[],'gridSetId':'EPSG:900913','zoomStart':00,'zoomStop':18,'format':'image/png','type':'seed','threadCount':2}}
data = json.dumps(data)
request.add_data(data)
req = urllib2.urlopen(request)
0

Thanks, alexgleith!

The problem in my simple code is:

authKey = 'admin:geoserver' request = urllib2.Request(url, json.dumps(params), headers)

should be replaced as:

authKey = base64.encodestring('%s:%s' % (un, pw)).replace('\n', '')
request = urllib2.Request(url)
for k in headers.keys():
    request.add_header(k, headers[k])
