'str' does not support Python 3 buffer interface error for oauth

Question

import json import gspread from oauth2client.client import SignedJwtAssertionCredentials json_key = json.load(open('Crowds-9569176f5988.json')) scope = ['https://spreadsheets.google.com/feeds'] credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope) #gc = gspread.authorize(credentials) 

Error:

 Traceback (most recent call last): File "C:\Users\sony\Desktop\Python\new.py", line 8, in <module> credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope) File "C:\Python34\lib\site-packages\oauth2client\util.py", line 137, in positional_wrapper return wrapped(*args, **kwargs) File "C:\Python34\lib\site-packages\oauth2client\client.py", line 1469, in __init__ self.private_key = base64.b64encode(private_key) File "C:\Python34\lib\base64.py", line 62, in b64encode encoded = binascii.b2a_base64(s)[:-1] TypeError: 'str' does not support the buffer interface 

I tried to encode a string using .encode() , but gspread.authorize() does not support this type. This is [documentation] [1], which, apparently, does not help much. I am using Python 3.4. I think the documentation code only works for versions up to 3.

EDIT:

 credentials = SignedJwtAssertionCredentials.from_json(json_key['client_email'], json_key['private_key'], scope) 

Traceback (last last call): File "C: \ Users \ sony \ Desktop \ Python \ new.py", line 9, in credentials = SignedJwtAssertionCredentials.from_json (json_key ['client_email'], json_key ['private_key'], scope ) TypeError: from_json () takes 2 positional arguments, but 4 are given [Finished in 1.0 with exit code 1]

Answer 1

You are using Python3.x, where string not the same type as Python 2.x. You need to pass it in bytes (encode it).

Here is a simple solution that works well for me:

 credentials = SignedJwtAssertionCredentials( json_key['client_email'] , bytes(json_key['private_key'], 'UTF-8') , scope) 

Answer 2

There is a solution in this error report, but I have not tried it myself. https://github.com/burnash/gspread/issues/224
