Logging in with cookies does not work.

[szymonszl]

Description of the problem

Trying to pass a set of cookies to the Client fails with two exceptions, one describing the fail to load them and another one from aiohttp related to it. It seems to be a problem with loading a cookie jar from the dict. The client logs in correctly, but it needs to log in every time instead of reusing sessions which increases the chance of getting blocked by facebook.

Code to reproduce

#!/usr/bin/env python3
import fbchat
import json
import asyncio

with open('bote/config.json') as fd:
    config = json.load(fd)
    email = config['login']
    password = config['password']
cookie_file = 'cookies.json'

loop = asyncio.get_event_loop()
loop.set_debug(True)

async def start():
    with open(cookie_file, 'r') as fd:
        cookies = json.load(fd)
    client = fbchat.Client(loop=loop)
    await client.start(email, password, session_cookies=cookies)
    with open(cookie_file, 'w') as fd:
        cookies = client.get_session()
        json.dump(cookies, fd)
    client.listen()
loop.run_until_complete(start())
loop.run_forever()

The cookie stuff is a bit hacky (relying on private aiohttp fields), so maybe try pickle instead of json for storing the cookies.

[PythonNut]

I can confirm logging in with cookies seems to work fine if you pickle the session_cookies.

[syspic]

I keep getting null/None as the cookies when I client.get_session()

Also how do you use the pickel thing?
