Python - Gspread请求错误401

时间：2017-08-28 08:02:42

标签： python python-3.x google-sheets gspread discord.py

我目前正在创建一个连接到Google电子表格（gspread）的Discord-bot。 但是在我运行它一段时间之后它开始发出错误，它再也无法连接到我的gspread（除非我重新启动它）。

我收到的错误：（https://hastebin.com/odutucawuv.tex）

我正在使用的其中一个函数，如果有任何帮助来理解上面的问题，我可以提供更多的代码，如果有必要修复它：

import discord
import asyncio
import random
import pickle
import os
import gspread
import time

from oauth2client.service_account import ServiceAccountCredentials
from discord.ext import commands

prefix = '!'

def returnPrefix():
    global prefix
    return prefix

bot = commands.Bot(returnPrefix())

scope = ['https://spreadsheets.google.com/feeds']
credentials = 
ServiceAccountCredentials.from_json_keyfile_name('GoogleSpreadsheetCreds.json', scope)
gc = gspread.authorize(credentials)
sh = gc.open("MyWorksheet")
worksheet = sh.sheet1


@bot.event
async def on_ready():
        print('Logged in as')
        print(bot.user.name)
        print(bot.user.id)
        print('-----')
        await bot.change_presence(game=discord.Game(name='Stackoverflow'))



@bot.command(pass_context=True)
@commands.has_role("Premium")
async def sub(ctx, member: discord.Member = None):
    global cell_name
    if member is None:
        member = ctx.message.author

    #Delete user_command.
    await bot.delete_message(ctx.message)

    #Retrieve user from commander.
    Username = '{0}'.format(member)

    try:
        #Try to find the username in spreadsheet.
        cell_name = worksheet.find(Username)
    except: #If we dont find the username.
        await bot.say("Your name ("+Username+") was not found, please contact someone for help.")

    if cell_name.value == Username: #If we find the username.
        #Retrieve some values.
        val = worksheet.cell(cell_name.row, cell_name.col+4)
        val_date = worksheet.cell(cell_name.row, cell_name.col+3)
        remaining_days = val.value
        remaining_date = val_date.value

        #Send a message to a member.
        await bot.send_message(member,
                            "```Username: "+ Username+
                            "\nRemaining days: "+remaining_days+
                            "\nDate for expiration: "+remaining_date+"```")

您的访问令牌会在一段时间后过期。来自OAuth 2.0 docs：

  
      
  1. 如有必要，请刷新访问令牌。
    2.         

    访问令牌的生命周期有限。如果您的应用需要在单个访问令牌的生命周期之后访问Google API，则可以获取刷新令牌。刷新令牌允许您的应用程序获取新的访问令牌。

         

    注意：在安全的长期存储中保存刷新令牌，只要它们仍然有效，就继续使用它们。限制适用于每个客户端 - 用户组合以及所有客户端中的每个用户发布的刷新令牌的数量，并且这些限制是不同的。如果您的应用程序请求足够的刷新令牌超过其中一个限制，则较旧的刷新令牌将停止工作。

我不相信gspread能够处理刷新令牌。您可能只能捕获此异常并根据需要重新进行身份验证。

编辑：

查看gspread来源后，我认为您可能只需拨打gc.login()

即可刷新您的令牌

这issue几年前已经gspread提交了def add_row(row): try: gs_client = gspread.authorize(creds) gs_worksheet = gs_client.open("foo").sheet1 if creds.access_token_expired: gs_client.login() # refreshes the token gs_worksheet.append_row(row) except Exception, e: traceback.print_exc() 但是因为没有明显原因而被关闭了。解决问题的方法是one approach：

gc.login()

但我觉得这太过分了。您应该可以在try:阻止之前致电gc.login() try: #Try to find the username in spreadsheet. cell_name = worksheet.find(Username) except: #If we dont find the username. ：

redis.Redis()

这里唯一合理的罪魁祸首是您的帐户凭据。尝试在Google Developer Console上创建新凭据并使用它。
