读取 pandas 数据框中的 google 电子表格

Question

在 API 身份验证方面经验不足，但我不知道如何阅读 Google Sheet 与我分享的 Python。

我试过：

import gspread
from oauth2client.service_account import ServiceAccountCredentials

scope = ['https://spreadsheets.google.com/feeds',
         'https://www.googleapis.com/auth/drive']

credentials = ServiceAccountCredentials.from_json_keyfile_name('/Users/alexiseggermont/Downloads/Accountable-7b29dac08324.json', scope)

gc = gspread.authorize(credentials)

wks = gc.open("mysheet").sheet1

这给了我第 2 行 ImportError: cannot import name 'opentype'。

然后我尝试了：

import oauth2client.client, oauth2client.file, oauth2client.tools
import gspread

flow = oauth2client.client.OAuth2WebServerFlow(client_id, client_secret, 'https://spreadsheets.google.com/feeds')
storage = oauth2client.file.Storage('credentials.dat')
credentials = storage.get()
if credentials is None or credentials.invalid:
    import argparse
    flags = argparse.ArgumentParser(parents=[oauth2client.tools.argparser]).parse_args([])
    credentials = oauth2client.tools.run_flow(flow, storage, flags)

gc = gspread.authorize(credentials)

# when this cell is run, your browser will take you to a Google authorization page.
# this authorization is complete, the credentials will be cached in a file named credentials.dat

这会打开一个 window 询问我是否要允许我的应用程序访问我的工作表，然后我单击“是”。但是 sheet = gc.open("mysheet").sheet1 给了我一个权限错误：

APIError: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission"
   }
  ],
  "code": 403,
  "message": "Insufficient Permission"
 }
}

我发现解决此错误的唯一建议是更改 'scope' 变量，但该代码中没有使用范围变量，所以我很困惑。

Answer 1

您可以使用空格添加多个范围。那你可以试试下面的修改吗？

发件人：

flow = oauth2client.client.OAuth2WebServerFlow(client_id, client_secret, 'https://spreadsheets.google.com/feeds')

收件人：

flow = oauth2client.client.OAuth2WebServerFlow(client_id, client_secret, 'https://spreadsheets.google.com/feeds https://www.googleapis.com/auth/drive')

注：

在您运行修改脚本之前，请删除credentials.dat。这样，credentials.dat 使用新范围创建。
在我的环境中，我确认当范围仅为https://spreadsheets.google.com/feeds时，会发生同样的错误。当范围为 https://spreadsheets.google.com/feeds https://www.googleapis.com/auth/drive 时，不会发生错误。

Answer 2

还有 Gspread-Pandas 库本身，其中的文档对 Oauth 部分有一个简单的介绍，并且以更简单的方式： https://github.com/aiguofer/gspread-pandas

Before using, you will need to download Google client credentials for your app.

Client Credentials To allow a script to use Google Drive API we need to authenticate our self towards Google. To do so, we need to create a project, describing the tool and generate credentials. Please use your web browser and go to Google console and :

Choose Create Project in popup menu on the top. A dialog box appears, so give your project a name and click on Create button. On the left-side menu click on API Manager. A table of available APIs is shown. Switch Drive API and click on Enable API button. Do the same for Sheets API. Other APIs might be switched off, for our purpose. On the left-side menu click on Credentials. In section OAuth consent screen select your email address and give your product a name. Then click on Save button. In section Credentials click on Add credentials and switch OAuth 2.0 client ID. A dialog box Create Cliend ID appears. Select Application type item as Other. Click on Create button. Click on Download JSON icon on the right side of created OAuth 2.0 client IDs and store the downloaded file on your file system. Please be aware, the file contains your private credentials, so take care of the file in the same way you care of your private SSH key; i.e. move downloaded JSON to ~/.config/gspread_pandas/google_secret.json (or you can configure the directory and file name by directly calling gspread_pandas.conf.get_config Thanks to similar project df2gspread for this great description of how to get the client credentials.

User Credentials Once you have your client credentials, you can have multiple user credentials stored in the same machine. This can be useful when you have a shared server (for example with a Jupyter notebook server) with multiple people that may want to use the library. The first parameter to Spread must be the key identifying a user's credentials. The first time this is called for a specific key, you will have to authenticate through a text based OAuth prompt; this makes it possible to run on a headless server through ssh or through a Jupyter notebook. After this, the credentials for that user will be stored (by default in ~/.config/gspread_pandas/creds or you can manually set it in GSPREAD_PANDAS_CONFIG_DIR env var) and the tokens will berefreshed automatically any time the tool is used.

Users will only be able to interact with Spreadsheets that they have access to.

Handling Authentication In the backend, the library is leveraging Google's oauth2client <http://oauth2client.readthedocs.io/en/latest/__ to handle authentication. It conveniently stores everything as described above so that you don't have to worry about boiler plate code to handle auth. However, if you need to customize how you handle authentication you can do so in a few different ways. You can change the directory where everything is stored using the GSPREAD_PANDAS_CONFIG_DIR env var. You can also generate your own oauth2client.client.OAuth2Credentials and pass them in when instanciating a Client or Spread object. For other ways to customize authentication, see gspread_pandas.conf.get_config and gspread_pandas.conf.get_creds
