python - Google Drive API 快速入门 UnicodeDecodeError：

问题描述

我尝试按照谷歌驱动api教程的介绍：developers.google.com/drive/api/v3/quickstart/python，但是下面运行示例文件quickstart.py时卡住了：

from __future__ import print_function
from googleapiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools


SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'

def main():
store = file.Storage('token.json')
creds = store.get()
if not creds or creds.invalid:
    flow = client.flow_from_clientsecrets('credentials.json', SCOPES)
    creds = tools.run_flow(flow, store)
service = build('drive', 'v3', http=creds.authorize(Http()))

results = service.files().list(
    pageSize=10, fields="nextPageToken, files(id, name)").execute()
items = results.get('files', [])

if not items:
    print('No files found.')
else:
    print('Files:')
    for item in items:
        print(u'{0} ({1})'.format(item['name'], item['id']))

if __name__ == '__main__':
    main()

我得到如下错误：

C:\Users\mhlai.TARI\AppData\Local\Programs\Python\Python37-32\lib\site-packages\oauth2client\_helpers.py:255: UserWarning: Cannot access token.json: No such file or directory

Traceback (most recent call last):

    hostname, aliases, ipaddrs = gethostbyaddr(name)


UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbf in position 0: invalid start byte

问题一：介绍中找不到token.json，不知道有没有必要。

问题 2：我可以为错误信息做什么？

任何答案都有帮助，非常感谢。

我的开发环境是python3.7
