gspread给出TypeError:尝试登录时需要字节

Question

我正在尝试使用Google电子表格OAuth和gspread库。我在发送凭据时遇到TypeError: expected bytes, not str异常。我怎么解决这个问题？在

import gspread
import json
from oauth2client.client import SignedJwtAssertionCredentials

json_key = json.load(open('Test for gspread-78c678a7fb15.json'))
scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)
gc = gspread.authorize(credentials)

^{pr2}$

Answer 1

密钥是字符串，需要编码为字节。将credentials =替换为以下内容：

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