python quickstart

Question

这是我的代码的一部分：

 if os.path.exists('token.pickle'):
                with open('token.pickle', 'rb') as token:
                    creds = pickle.load(token)
            if not creds or not creds.valid:
                if creds and creds.expired and creds.refresh_token:
                    creds.refresh(Request())

如果凭据过期，则必须刷新。在Windows上，该部分有效，但在Linux上，我得到一个错误（在最后一个字符串上）：

('invalid_scope: Some requested scopes were invalid. {invalid=[a, c, d, e, g, h, i, l, m, ., /, o, p, r, s, t, u, v, w, :]}', '{\n  "error": "invalid_scope",\n  "error_description": "Some requested scopes were invalid. {invalid\\u003d[a, c, d, e, g, h, i, l, m, ., /, o, p, r, s, t, u, v, w, :]}",\n  "error_uri": "http://code.google.com/apis/accounts/docs/OAuth2.html"\n}')

Answer 1

我能够重现该错误，我相信如果您将作用域声明如下，将解决该问题：

"scopes": "https://googleapis.com/auth/drive"

代替

"scopes": "googleapis.com/auth/drive"

它肯定应该双向工作，但不行。

请让我知道这是否可以解决。

您缺少用于授权请求的适当范围。您可能要考虑先遵循Google的教程。

python quickstart

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']

def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files the user has access to.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    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()

我是python初学者，遇到类似问题。我编辑了https://developers.google.com/drive/api/v3/quickstart/python，以便能够创建事件。我将范围更改为：

SCOPES = 'https://www.googleapis.com/auth/calendar'

起初，我的应用程序运行良好，但随后很奇怪。第二天，它崩溃了，我必须删除令牌才能再次运行该应用程序。当我运行它时，我必须再次允许访问（通过打开的浏览器）。然后效果很好，但第二天又不能了；）

问题是令牌在3600秒后过期。这就是奇怪行为的原因。令牌过期后，它会运行代码以刷新现有令牌（creds.refresh(Request())），但是在Windows上却出现错误：

RefreshError('invalid_scope: Some requested scopes were invalid. {invalid=[a, c, d, e, g, h, i, l, m, ., n, /, o, p, r, s, t, u, w, :]}', '{\n  "error": "invalid_scope",\n  "error_description": "Some requested scopes were invalid. {invalid\\u003d[a, c, d, e, g, h, i, l, m, ., n, /, o, p, r, s, t, u, w, :]}",\n  "error_uri": "http://code.google.com/apis/accounts/docs/OAuth2.html"\n}'),)

，应用崩溃。从错误消息中我感到困惑。

当您删除token.pickle时，它需要再次通过浏览器进行授权，之后该应用程序又可以运行3600s；）很多小时我一直在寻找问题所在。

最后我找到了。应该是：

SCOPES = ['https://www.googleapis.com/auth/calendar']

缺少 [和] 括号！！！这是造成上述错误的原因。

现在它对我有用。

提示：如果要测试应用程序的到期时间和令牌刷新是否有效，则只需将系统时钟更改为将来的某个日期即可。
