Not possible to set content-type to application/json using urllib2
I got hit by the same stuff and came up with this little gem:
import urllib2
import simplejson as json
class ChangeTypeProcessor(BaseHandler):
def http_request(self, req):
req.unredirected_hdrs["Content-type"] = "application/json"
return req
opener = urllib2.build_opener()
self.opener.add_handler(ChangeTypeProcessor())
response = opener.open('http://localhost:8000',json.dumps({'a': 'b'}))
You just add a handler for HTTP requests that replaces the header that OpenerDirector
previously added.
If you want to set custom headers you should use a Request
object:
import urllib2
import simplejson as json
opener = urllib2.build_opener()
req = urllib2.Request('http://localhost:8000', data=json.dumps({'a': 'b'}),
headers={'Content-Type': 'application/json'})
response = opener.open(req)
