【问题描述】：

我目前正在制作一个连接到 Google 电子表格 (gspread) 的 Discord-bot。但是在我运行它一段时间后，它开始发出错误并且它无法再连接到我的 gspread（除非我重新启动它）。

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

During handling of the above exception, another exception occurred:

如果我正在使用的功能之一有助于理解上述问题，如果需要修复它，我可以提供更多代码：

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+"```")

【解决方案1】：

您的访问令牌会在一段时间后过期。来自OAuth 2.0 docs：

如有必要，请刷新访问令牌。

访问令牌的生命周期有限。如果您的应用程序需要在单个访问令牌的生命周期之外访问 Google API，它可以获得刷新令牌。刷新令牌允许您的应用程序获取新的访问令牌。

注意：将刷新令牌保存在安全的长期存储中，只要它们仍然有效，就可以继续使用它们。限制适用于每个客户端-用户组合以及所有客户端的每个用户发出的刷新令牌的数量，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以超过其中一个限制，则旧的刷新令牌将停止工作。

我不相信gspread 具备处理刷新令牌的能力。您可能只是能够捕获此异常并根据需要重新进行身份验证。

编辑：

查看gspread 源后，我认为您可能只需调用gc.login() 即可刷新您的令牌

编辑：

这个issue 是在几年前与gspread 一起提交的，但由于没有明显的原因而被关闭。这是one approach来解决它：

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()

但我认为这太过分了。您应该可以在 try: 块之前调用 gc.login()：

gc.login()
try:
    #Try to find the username in spreadsheet.
    cell_name = worksheet.find(Username)
except: #If we dont find the username.

【讨论】：

谢谢，我会试试的！所以 gc.login() 不需要输入？
对，没有参数。您需要在访问令牌过期后调用它。

【解决方案2】：

这里唯一可能的罪魁祸首是您的帐户凭据。尝试在您的 Google Developer Console 上创建新凭据并使用它。
