WSO2 API Manager compatibility with Python

问题


I want to know if WSO2 API Manager is compatible with Python and PHP based restful services or not?
I have several webservices which are developed on JavaEE, Python and PHP.
Except JavaEE, no other platform is communicating with WSO2.
On Python, I don't receive any RAW payload in my POST requests from WSO2. These services are working fine and can communicate with them via REST Console.

Please see my other STACKOVERFLOW POST for details.

I need to know how I can consume Python services just like my JavaEE services.

--UPDATE 2--

Both WSO2 AM and Python server use default settings

WSO2 Log - Python server response (NO TRY CATCH at server but root cause id empty payload)

Python Service Code:

Using Django

from django.shortcuts import render
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt
def path(request):
    try:
        print request
        if request.method == 'GET':
            return HttpResponse("Hello GET Django")
        elif request.method =='POST':
            print request.body #ERROR OCCURS HERE
            return HttpResponse(request.body)
    except Exception, e:
        print e
        return HttpResponse(e)

Using Google App Engine

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello app world!')


class PostHandler(webapp2.RequestHandler):
    def post(self):
        data = self.request.body #ERROR OCCURS HERE
        print data
        self.response.write('SUCCESS')


app = webapp2.WSGIApplication([
    ('/', MainHandler),
    ('/data', PostHandler)
], debug=True)

These services are working fine and I am able to communicate with them via Rest Console.
But through WSO2's rest console, I am unable to pass my payload to service.
Payload either comes empty or I get Malformed Request Error.

I have added Content-Length in request as per solution Still content length in request header also comes 0 like Content-Length: 0

Services made using node.js and JEE works fine!!

Why there is issue communicating with Python from WSO2???
