Question

我正在用Python编写一个应用程序，该应用程序可以从Google表格中读取数据，但我也希望能够以编程方式添加命名范围，以减少非常繁琐且易于出错的输入。除单元格B1中的值foo之外，该工作表为空。读取部分可以正常工作，如本示例中所示，但是在尝试编写时，我得到了401，未授权。尽管事实上我正在使用https://developers.google.com/sheets/api/guides/authorizing

中所述的范围https://www.googleapis.com/auth/spreadsheets

为了编写范围，我使用了https://developers.google.com/sheets/api/samples/ranges

中的示例代码

整个程序如下：

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

# Setup the Sheets API
SCOPES = 'https://www.googleapis.com/auth/spreadsheets'
store = file.Storage('credentials.json')
creds = store.get()
if not creds or creds.invalid:
    flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
    creds = tools.run_flow(flow, store)
service = build('sheets', 'v4', http=creds.authorize(Http()))

# Specific spreadsheet, actual ID hidden in this example
SPREADSHEET_ID = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'


# Utility functions
def add_named_range():
    url = 'https://sheets.googleapis.com/v4/spreadsheets/%s:batchUpdate'%SPREADSHEET_ID
    data = '''{
      "requests": [
        {
          "addNamedRange": {
            "namedRange": {
              "name": "test",
              "range": {
                "sheetId": "%s",
                "startRowIndex": 1,
                "endRowIndex": 1,
                "startColumnIndex": 1,
                "endColumnIndex": 1,
              },
            }
          }
        }
      ]
    }
    '''%SPREADSHEET_ID
    response = requests.post(url, data=data)
    return response

def get_value_from_range(range_name, spreadsheetId=SPREADSHEET_ID):
    result = service.spreadsheets().values().get(spreadsheetId=SPREADSHEET_ID,
                                        range=range_name).execute()
    if not 'values' in result.keys():
        return None
    else:
        return result['values'][0][0]

print(get_value_from_range('data'))
res = add_named_range()
print(res.text)

，运行时的打印输出为

foo
{
  "error": {
    "code": 401,
    "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "status": "UNAUTHENTICATED"
  }
}

因此该程序能够读取数据，但不能写入，因此要添加一个命名范围。我在这里做什么错了？

将命名范围添加到Google工作表
