Authenication Coinbase

[Bandit253]

After starting the bot I get this... TypeError: Unicode-objects must be encoded before hashing seems to be in the creation of the signature

Steps to reproduce the behavior:

1. Configured the config
2. Run bot with CB config
3. See error

Expected behavior Should print message block describing config, then continue

I have ensured these, API_Key, API_Secret, API_PASS work with a very slightly different version of class CBProAuth(AuthBase):

I had started my own project before finding this excellent project. I found that the example ode offered on the API docs does not work 'as-is' I have confirmed the Binance interface is working just fine

This is my version, that works

`class CBProAuth(AuthBase):
    # Provided by CBPro: https://docs.pro.coinbase.com/#signing-a-message
    def __init__(self, api_key, secret_key, passphrase):
        self.api_key = api_key
        self.secret_key = secret_key
        self.passphrase = passphrase

    def __call__(self, request):
        timestamp = str(time.time())
        message = ''.join([timestamp, request.method, request.path_url, (request.body or '')])
        request.headers.update(get_auth_headers(timestamp, message,
                                                self.api_key,
                                                self.secret_key,
                                                self.passphrase))
        return request

def get_auth_headers(timestamp, message, api_key, secret_key, passphrase):
    message = message.encode('ascii')
    hmac_key = base64.b64decode(secret_key)
    signature = hmac.new(hmac_key, message, hashlib.sha256)
    signature_b64 = base64.b64encode(signature.digest()).decode('utf-8')
    return {
        'Content-Type': 'Application/JSON',
        'CB-ACCESS-SIGN': signature_b64,
        'CB-ACCESS-TIMESTAMP': timestamp,
        'CB-ACCESS-KEY': api_key,
        'CB-ACCESS-PASSPHRASE': passphrase
    }`

I'm not aware of anyone else having this issue but I'll take a look.

Can you please answer the following?

1. What platform are you running on the bots on?
2. This issue is related to Coinbase Pro only right?
3. Is this a constant or intermittent issue?

[Bandit253]

It does seem odd it's just me.

Window 10 Yes, Binance works fine I first experienced the issue using the example code off the Coinbase pro API site, then I found the supplied code and that worked. Then I found this project and the problem returned. Is that intermittent? I could change this code but I really want to divert from this code base. Thanks for a excellent project.

@Bandit253 could you please tell your python version as well? Thanks!

[Bandit253]

No problem @lazydroid

Python 3.9.4 - 64 bit

[lazydroid]

thanks! could you please provide the minimum changes that differ between the current code base and the one that works for you?

(I don't have access to coinbase to check, please, be precise =)

[Bandit253]

yes that is the straight copy of what works - that security stuff does my head in - I'm not going to be changing any of it.

Thanks for making the change

Is this resolved?
