'str' 不支持缓冲区接口 Python 3 oauth 错误

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)

错误：

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

我尝试使用 .encode() 对字符串进行编码，但 gspread.authorize() 不支持这种类型。这是 [documentation][1]，显然没有太大帮助。我正在使用 Python 3.4。我认为文档代码仅适用于 3.

之前的版本

编辑：

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

Traceback (most recent call last): 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 were given [Finished in 1.0s with exit code 1]

credentials = SignedJwtAssertionCredentials.from_json(json_key)

Answer 1

这个错误报告中有一个解决方案，但我自己没有尝试过。 https://github.com/burnash/gspread/issues/224

Answer 2

您正在使用 Python3.x，其中 string 与 Python 2.x 的类型不同。您需要将其转换为字节（对其进行编码）。

这里有一个很适合我的简单解决方案：

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