Hi. I successfully decoded a test cookie and the result was as follows :

1. b'{"_fresh":true,"_id":{" b":"SOMEVALUES="},"csrf_token":{" b":"SOMEVALUES=="},"user_id":"SOMEINT"}'

However, when I try to re-encode it, following error occurred :

error: unrecognized arguments: b_id:{ b:SOMEVALUES=} bcsrf_token:{ b:SOMEVALUES==} buser_id:SOMEINT

I removed the "b" values like below

2. {"_fresh":true,"_id":{" b":"SOMEVALUES="},"csrf_token":{" b":"SOMEVALUES=="},"user_id":"SOMEINT"}

However, this does not give me exact cookie value that I input in decoding stage.

How can I reproduce the same cookie with value from 1. ?

Thank you

Hey! Sorry for a late response, I was busy with exams.

Sadly, as for Python 2, I have no idea what needs to be done.

Mind you publish code onto Pypi? Thanks

I also noticed you've done substantial changes to the code! Great? How sure if its a bug or not (if it is, it's probably some of my mistakes), but for Python 3.6+, when trying to decode, it returns bytestream, not String

thanks

Hey,
nice tool, one little request:
At the moment it is not possible to encode the cookie without a secret key, if you provide an empty -s '' parameter you will receive an error:
[Encoding error] 'NoneType' object has no attribute 'dumps'

would be nice if you implement this.

Thanks & BR,

This is code from app.py:

app.config["SECRET_KEY"] = str(random.random())

And when i run this cmd:

python flask_session_cookie_manager3.py decode -c ".eJyrVipOTS5KLclLzE1VslKKKTUzN0qMKTU3TzUFkqZGFkARI2NzEwszAyUdpdLi1CK4StM0AyOgrEGacUypSapJEpBtmmyqVAsAQfAZaA.Yay2mA.Q51Q7QbVLWIssD3Pfv63Bu4czL0" 

(The session content is from web cookie)

It still work! And i can see what I've just set on my server.

Who know why? Strongly thanks.

I used this repo to encode a cookie using your demo:

python flask_session_cookie_manager3.py encode -s '.{y]tR&sp&77RdO~u3@XAh#TalD@Oh~yOF_51H(QV};K|ghT^d' -t '{"number":"326410031505","username":"admin"}'

But, unfortunately, it didn't work, and gave this error:

python flask_session_cookie_manager3.py encode -s '.{y]tR&sp&77RdO~u3@XAh#TalD@Oh~yOF_51H(QV};K|ghT^d' -t '{"number":"326410031505","username":"admin"}'
[Encoding error] malformed node or string: <ast.Name object at 0x00000210548ECBE0>

I'm using Windows 11 with python==3.9.13, itsdangerous==2.0.1, flask==1.1.2.

Any advice?

你好，在py3.9的环境下，运行报错：[Encoding error] dictionary update sequence element #0 has length 1; 2 is required

可以看下是什么问题么，非常感谢
