GAE python: How to post/retrieve json data between two applications?

Question

I have two gae apps and want to send data between the two.

First app(localhost):

import requests

class PostHandler(Handler):
    def get(self):
        post_url = "https://www.example.com/api/post"
        datas = lib.data_cache()
        output = [data.as_dict() for data in datas]
        headers = {'content-type': 'application/json'}
        #self.write(output)
        r = requests.post(post_url, data=json.dumps(output), headers=headers)

www.example.com:

class RetrieveHandler(Handler):
     def post(self):
        post_data = self.requests.POST.items()
        #What should I do here? Is this correct?

I'm not getting the post_data properly. Anyone knows where I can get documentation on this in python and app engine? Any advice would be grateful. Thanks.

Answer 1

Using webapp2, you can extract POST request body data with a webapp2.RequestHandler instance like this

data = self.request.body

Because you are sending JSON, you probably want to parse that right away

data = json.loads(self.request.body)

Also see https://webapp-improved.appspot.com/guide/request.html#common-request-attributes for what other info you can get from the request object.
