如何将 gspread 与 aiohttp 集成

Question

我正在尝试使用 gspread，但我需要该库与我正在使用的另一个异步库很好地融合。

在深入了解 gspread 的文档后，我发现了这个我可以使用的函数：

class gspread.Client(auth, session=None)
An instance of this class communicates with Google API.

Parameters: 
auth – An OAuth2 credential object. Credential objects are those created by the oauth2client library. https://github.com/google/oauth2client
session – (optional) A session object capable of making HTTP requests while persisting some parameters across requests. Defaults to requests.Session.

这给了我一个可选的 session 参数。我将如何指定会话以使用 aiohttp？

我写了一些测试代码，编译正常，但是运行代码崩溃了。

import aiohttp
import gspread
import random
from oauth2client.service_account import ServiceAccountCredentials

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

creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json', scope)
c = gspread.authorize(creds)
client = gspread.Client(auth=c, session=aiohttp.ClientSession)
sheet = client.open_by_key('1Hkwo9gSpk3NjgPLPkG8kh0zBNw2nxsYWRw0cVdn0JA0')

ws = sheet.get_worksheet(0)
rcount = ws.row_count
msg = ws.cell(random.randint(1,rcount),1).value
print(msg)

我收到的错误消息如下：

有什么想法吗？

Answer 1

无法在 gspread (3.0.1) 的当前版本中使用 aiohttp。 gspread 库使用同步调用，aiohttp 使用异步调用。

请重新考虑使用 requests 或 httplib2 等兼容库。

对于任何想知道的人，一旦我发布了这个问题，我发现有人为 gspread 制作了一个异步包装器。查看图书馆 here 并向他表示感谢。我当然是！
