描述

Hey, I'm trying to fetch out the data with JSON I've spent way too much time on google and tried every single solution with no success.. when I send the request it raises an json.decoder.JSONDecodeError Exception. maybe can you help?

class TextOcrRes:
    def on_post(self, req, resp):
        """Handles Text POST requests"""
        json_data = json.loads(req.bounded_stream.read().decode("utf-8")) # json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
        print(json_data)

What I'm sending:

r = requests.post("http://x.xx.xx.xx/translate", data={'image_data':'message'}) I'm on python 3.6.8

研究方向
The user is trying to send JSON data but uses the 'data' parameter in requests.post, which sends URL encoded form data. The server code expects JSON via json.loads on the raw stream. The solution is to either send JSON using the 'json' parameter in requests or change the server to handle form data. For documentation purposes, adding a FAQ entry on how to send JSON requests to Falcon apps would help. See Falcon documentation on request parsing: https://falcon.readthedocs.io/en/stable/api/request.html.
