Flask inside docker does not get json requests-CodePudding

My flask application, whose works inside a docker container, does not get json requests. When I sent json request I get tuple in response, looks like that(Ellipsis, Ellipsis)

My endpoint

class WhoisInfo(Resource):
    def post(self):
        if request.method == "POST":
           logger.debug("got request method POST")
        if request.is_json:
            logger.debug("is json")
            logger.debug(request.args.get('host'))
            logger.debug(request.get_data())
    return {"error": "Not information about this zone "}, 400
api_v1.add_resource(WhoisInfo, "/api/whois/")

debug output

backend_1  | 2021-10-03 13:03:30.583 | DEBUG    | api.views:post:57 - b'{"host": "8.8.8.8"}'

My request

import requests

url = "http://127.0.0.1:80/api/whois/"

payload={"host": "8.8.8.8"}
headers = {
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

CodePudding user response：

This problem come from the wrong Flask version, I used python3.8 and Flask 0.10.1, I changed Flask version to 2.0.2 and everything works.
