How to connect to Odoo database from an android application

Question

I am developping an Android application, and I'd like to retrieve data from an Odoo server.

For that I developped a custom module in Odoo, in which I created a controller.

My controller :

import json
import xmlrpc.client as xmlrpclib
from odoo import http
from openerp.http import Response

class resUserController(http.Controller):
    url = '<my url>'
    db = '<name of my database>'

    @http.route('/user/login', type='json', method='GET', auth='public')
    def get_login(self, **kwargs):
        username = kwargs.get('email')
        password = kwargs.get('password')
        common = xmlrpclib.ServerProxy('{}/xmlrpc/2/common'.format(self.url), allow_none=True)

        uid = common.authenticate(self.db, username, password, {})
        if uid:
            Response.status = '200 Succesful operation'
            json_result = {'token': uid}
            return json.dumps(json_result)
        Response.status = '400 Invalid credentials'
        return

When I call it from a python script to try it, it works fine and I get a <Response [200]> and a json {u'jsonrpc': u'2.0', u'result': u'{"token": 8}', u'id': None} with the id of the account I connect to.

But then I have an other function I call with an other route in the same controller, but with auth='user' this time, because I want the user to be able to see only informations he has rights on.

@http.route('/user/getInfo', type='json', method='GET', auth='user')
def get_info(self, **kwargs):
    uid = 1
    password = '<my admin password>'
    models = xmlrpclib.ServerProxy('{}/xmlrpc/2/object'.format(self.url), allow_none=True)
    info = models.execute_kw(self.db, uid, password, 'res.users',
                             'search_read', [[['id', '=', kwargs.get('token')]]],
                             {'fields': ['info']})[0]['invite_code']
    if info:
        Response.status = '200 Succesful operation'
        json_result = {'info': info}
        return json.dumps(json_result)
    Response.status = '404 User not found'
    return

This function works fine when I use auth='public', but when I go for auth='user', I get the following json response :

Response [200]

{  
    u'jsonrpc': u'2.0',   
    u'id': None,   
    u'error': {  
        u'message': u'Odoo Session Expired',   
        u'code': 100,  
        u'data': {  
            u'debug': u'Traceback (most recent call last):

            u'exception_type': u'internal_error',

            u'arguments': [u'Session expired'] 
        }  
    }  
}

I based my work on This documentation, which is an official Odoo doc, but here are the problems :

1 It ask me to write my admin password in each function, which seems dangerous.

2 After authentication, I get the id of my user, but no session token. Then how can I inform my function with auth='user' that I'm connected and to which user?

Here is my script to test my calls :

import requests
import json

url_connect = "<my url>/user/login"
url = "<my url>/user/getInfo"
headers = {'Content-Type': 'application/json'}
data_connect = {
                "params": {
                           "email": "<my test account email>",
                           "password": "<my test account password>",
                }
    }
data = {
        "params": {
                   "token": <my test account id>,
            }
       }
data_json = json.dumps(data)
r = requests.get(url=url_connect, data=json.dumps(data_connect), headers=headers)
print(r)
print(r.json())
r = requests.get(url=url, data=data_json, headers=headers)
print(r)
print(r.json())

Things to note:

• Never send credentials in a GET request
• All Odoo RPC requests are POST requests
• You don't need a custom login route if you use /web/session/authenticate
• The External API is intended to be used outside of odoo framework. When developing a module use self.env['< model >'] if inside a model or http.request.env['< model >'] if in a controller
• The call to /web/session/authenticate returns a json containing the session_id, which you have to pass it in the cookies to subsequent requests until you call /web/session/destroy to logout.

Here is an example using /web/session/autenticate:

import requests
import json

url_connect = "http://localhost:8069/web/session/authenticate"
url = "http://localhost:8069/web/session/get_session_info"

headers = {'Content-Type': 'application/json'}

data_connect = {
    "params": {
        "db": "demo1",
        "login": "admin",
        "password": "admin",
    }
}

data = {}

session = requests.Session()

r = session.post(url=url_connect, data=json.dumps(data_connect), headers=headers)

if r.ok:
    result = r.json()['result']

    if result.get('session_id'):
        session.cookies['session_id'] = result.get('session_id')

r = session.post(url=url, data=json.dumps(data), headers=headers)
print(r)
print(r.json())

To get the info from your controller you could use request.env.user which holds the logged user at the moment and since you specify auth='user' it is required to be a valid. The sample code might look like:

from odoo.http import request

class UserController(http.Controller):
  @http.route('/user/getInfo', type='json', method='POST', auth='user')
  def get_info(self, **kwargs):
    current_user = request.env.user

    Response.status = '200 Succesful operation'
    json_result = {'info': current_user.info}
    return json.dumps(json_result)

Very well write question, you have done the homework. This works for me to be able to authenticate the mobile users sessions using an api style requests.

@http.route([
    '/m/login/email',
], type='http', auth="public", website=True, methods=["POST"], csrf=False)
def users_login_email(self, **kwargs):
    if kwargs:
        data = json.loads(kwargs.keys()[0])
    else:
        data = json.loads(request.httprequest.data)

    email = data.get('email')
    password = data.get('password')

    if not request.session.db:
        setup_db()
    uid = request.session.authenticate(request.session.db, email, password)
    if uid:
        return self._user_details(uid)
    body = json.dumps({"body": ["Credenciales Incorrectas"]})
    return werkzeug.wrappers.Response(body, status=403, headers=[
        ('Content-Type', 'application/json'), ('Content-Length', len(body))
    ])

Also I didn't use auth='user' to don't let Odoo to mess with redirects and web stuffs checks. I use this annotation wrapper in my controllers routes that require an authenticated user to return the proper HTTP error status code

def check_user(f):
    @functools.wraps(f)
    def wrap(*args, **kwargs):
        if not request.session.db:
            setup_db()

        request.uid = request.session.uid

        if not request.uid:
            body = json.dumps({"body": ["Session Expired"]})
            return werkzeug.wrappers.Response(body, status=403, headers=[
                ('Content-Type', 'application/json'), ('Content-Length', len(body))
            ])

        return f(*args, **kwargs)

    return wrap

You could use it like this:

@check_user
@http.route([
    '/m/<int:shop_id>/cart/info',
], type='http', auth="public", website=True)
def cart_info(self, shop_id, **kwargs):
