【问题描述】：

我有以下代码尝试捕获 gspread.exceptions.APIError，通常是由于 Google 电子表格凭据超时造成的。 _open_sheet 请求一组新的凭据。

def _findRow(self, entry):
''' Return row index for row which contains "entry". '''
for i in range(10):
    try:
        cell = self.worksheet.find(email)
        return cell.row
    except gspread.exceptions.CellNotFound:
        return None
    except gspread.exceptions.APIError:
        # This occurs when we get a timeout of the authentication token
        # Need to reauthenticate
        self._open_sheet()
        continue
print('Leadsheet:find:: Failed to renew authorization after 10 attempts.')
return None

并且从以下堆栈跟踪中未捕获 gspread.exceptions.APIError：

}

关于这段代码发生了什么的任何线索？

【解决方案1】：

我遇到了同样的问题，但有效的是：

except gspread.CellNotFound:

【解决方案2】：

在出现此错误一段时间后，我在 Excel 表中写入数据时也会发生同样的情况。一旦我再次运行我的脚本，它就可以正常工作，但一段时间后会失败。

观察到的一件事是在写入数据时，如果它到达该表中行的末尾并且没有其他行要写入，那么它就会开始抛出这样的错误。

所以你需要像下面这样捕获这个异常：

    try:
        Sheet.update_cell(row, column, value="What ever value")t_term)
    except gspread.exceptions.APIError as UNAUTHENTICATED:
        print("Api error occurred for gspread due to authentication failure while writing What ever value.")
