Access json content of http post request with Klein in python

I have a simple http client in python that send the http post request like this:

import json
import urllib2
from collections import defaultdict as dd
data = dd(str)
req = urllib2.Request('http://myendpoint/test')
data["Input"] = "Hello World!"
response = urllib2.urlopen(req, json.dumps(data))

On my server side with Flask, I can define a simple function

from flask import request
@app.route('/test', methods = ['POST'])
def test():
    output = dd()
    data = request.json

And the data on server will be the same dictionary as the data on the client side.

However, now I am moving to Klein, so the server code looks like this:

@app.route('/test', methods = ['POST'])
@inlineCallbacks
def test(request):
    output = dd()
    data = request.json <=== This doesn't work

and the request that's been used in Klein does not support the same function. I wonder is there a way to get the json in Klein in the same way I got it in Flask? Thank you for reading this question.

Solution

Asaik Klein doesn't give you direct access to the json data, however you can use this code to access it:

import json

@app.route('/test', methods = ['POST'])
@inlineCallbacks
def test(request):
    output = dd()
    data = json.loads(request.content.read())  # <=== This will work
