Tornado PUT Request Missing Body

Question

I'm trying to make a put request using a tornado ASyncHTTPClient like so:

  data = { 'text': 'important text',
           'timestamp': 'an iso timestamp' }

  request = tornado.httpclient.HTTPRequest(URL, method = 'PUT', body = urllib.urlencode(data))

  response = yield Task(tornado.httpclient.ASyncHTTPClient().fetch, request)

However, when the request hits its desired endpoint, it appears not to have a body, despite said body being properly encoded and defined above. Is there something that I'm overlooking here?

If the other end is expecting JSON, you probably need to set a "Content-Type" header. Try this:

data = { 'text': 'important text',
       'timestamp': 'an iso timestamp' }

headers = {'Content-Type': 'application/json; charset=UTF-8'}

request = tornado.httpclient.HTTPRequest(URL, method = 'PUT', headers = headers, body = simplejson.dumps(data))

response = yield Task(tornado.httpclient.ASyncHTTPClient().fetch, request)

This way, the header tells the server you're sending JSON, and the body is a string that can be parsed as JSON.
