urllib2 and json

Question

I am trying to figure out how to do a POST request using urllib2 with the data being in JSON format. Can anyone help me with it?

I think you need to specify a content-type header if you want it to really work. Here you include a content-type header:

import json
import urllib2
data = json.dumps([1, 2, 3])
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
response = f.read()
f.close()
