[Python] Loading cookies in JSON format into requests

I've got some cookies sent over from a client to allow me to log into his server programatically without needing the credentials.

I'm using the requests package to make HTTP requests to his server. The problem is the cookies he has sent are all in JSON format and I can't seem to find any way to load these cookies.

Aside from writing a method to convert them into regular cookies are there any existing solutions to load these cookies?

Here is my current code:

def cookieLogin(cookies):

with open(cookies) as f:
cookies = requests.utils.cookiejar_from_dict(json.load(f)[0] )

session = requests.session()
session.cookies = cookies

r = session.get('https://example.com')


Cookie example:

[
{
"domain": ".example.com",
"hostOnly": false,
"httpOnly": false,
"name": "act",
"path": "/",
"sameSite": "no_restriction",
"secure": false,
"session": true,
"storeId": "0",
"value": "875",
"id": 1
},
{
"domain": ".example.com",
"expirationDate": 1479135421.720188,
"hostOnly": false,
"httpOnly": false,
"name": "c_user",
"path": "/",
"sameSite": "no_restriction",
"secure": true,
"session": false,
"storeId": "0",
"value": "109",
"id": 2
},
...
