make a controller in odoo to handle a json

Question

I am new to odoo and I have created a module with the scaffold command as follows:

"C:\Program Files (x86)\Odoo 11.0\python\python.exe" "C:\Program Files (x86)\Odoo 11.0\server\odoo-bin" scaffold api4"C:\Users\Carlos\Desktop\custom_addons"

and when i create this base redirect controller it works fine

# - * - coding: utf-8 - * -
from odoo import http
from odoo.http import request
import json
class Api4 (http.Controller):
    @ http.route ('/ api4 / api4 /', auth = 'public', website = True)
    def index (self):
        return request.redirect ('/ web /')

but when I create another @ http.route to receive a json and be able to process your data it doesn't work for me and the one I have done previously stops working.

    @ http.route ('/ api / json_get_request', auth = 'public', type = 'json', csrf = False)
    def jsontest (self, ** kw):
        return {'attribute': 'test'}

the code is basic but I wanted to see if sending any json would return {'attribute': 'test'} and instead it returned this:

{
    "jsonrpc": "2.0",
    "id": null,
    "error": {
        "code": 404,
        "message": "404: Not Found",
        "data": {
            "name": "werkzeug.exceptions.NotFound",
            "debug": "Traceback (most recent call last): \ n File \" C: \\ Program Files (x86) \\ Odoo 11.0 \\ server \\ odoo \\ http.py \ ", line 653, in _handle_exception \ n return super (JsonRequest, self) ._ handle_exception (exception) \ n File \ "C: \\ Program Files (x86) \\ Odoo 11.0 \\ server \\ odoo \\ http.py \", line 312, in _handle_exception \ n raise pycompat.reraise (type (exception), exception, sys.exc_info () [2]) \ n File \ "C: \\ Program Files (x86) \\ Odoo 11.0 \\ server \\ odoo \\ tools \\ pycompat.py \ ", line 86, in reraise \ n raise value.with_traceback (tb) \ nwerkzeug.exceptions.NotFound: 404 Not Found: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again. \ n ",
            "message": "404 Not Found: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.",
            "arguments": [],
            "exception_type": "internal_error"
        },
        "http_status": 404
    }
}

error postman

I don't know know if it's the problem but when you send a json request odoo force you to send your data in the key `data` — Charif DZ, Mar 14 '20 at 09:05

Add -d or --db-filter in your odoo-bin command to single out only one database. For e.g. python3 odoo-bin --addons-path addons,mymodules -d newdatabase. As far as I know, api with auth='public' raise this kind of error when there are multiple odoo databases.

Alternative solution is you can use endpoint with auth='user'. You will need to get login cookie first tho. More on this: How to connect to Odoo database from an android application

Hello Carlos Alberto Florio Luis,

1) Clear all the cache and history in your browser.

2) keep only one database  for use and remove other databases

or

1) Use **--db-filter dabase-name** to load a single database.

And make sure your route defines there has no whitespace opt-in('/api/json_get_request').

Thanks
