Question

我使用传播的python库制作了一个Worksheet类。这是我的代码：

from oauth2client.service_account import ServiceAccountCredentials
import time
import gspread
import requests
import os

DIRNAME = os.path.dirname(__file__)

class Wksh:

    credentials_google_sheet = ServiceAccountCredentials.from_json_keyfile_name(os.path.join(DIRNAME, 'credentials/gs_credentials.json'),['https://spreadsheets.google.com/feeds'])
    gc = gspread.authorize(credentials_google_sheet)    

    worksheet_id = None
    sheet_name = None
    sheet = None

    def __init__(self,wksh_id,sh_name):
        while True:
            try:
                self.worksheet_id = wksh_id
                self.sheet_name = sh_name
                self.sheet = self.gc.open_by_key(wksh_id).worksheet(sh_name)
                break
            except (gspread.exceptions.HTTPError, gspread.exceptions.requests, gspread.exceptions.RequestError) as e: 
                if e[0] == 401:
                    self.gc.login()
                elif e[0] == 500:
                    time.sleep(10)
                else:
                    print 'init'
                    print e
                    break
            except requests.exceptions.ConnectionError as e:
                time.sleep(10)
            except requests.exceptions.ChunkedEncodingError as e:
                time.sleep(20)

    def write(self,cell,value):
        while True:
            try:
                self.sheet.update_acell(cell,value)
                break
            except (gspread.exceptions.HTTPError, gspread.exceptions.requests, gspread.exceptions.RequestError) as e:
                if e[0] == 401:
                    self.gc.login()
                elif e[0] == 500:
                    time.sleep(10)
                else:
                    print 'write'
                    print e
                    break
            except requests.exceptions.ConnectionError as e:
                time.sleep(10)
            except requests.exceptions.ChunkedEncodingError as e:
                time.sleep(20)

这很好用，但是每当有请求错误时，即使我尝试捕获错误也得到：

AttributeError: 'module' object has no attribute 'RequestError' or 
AttributeError: 'module' object has no attribute 'HTTPError'

为什么会这样？我需要在例外之前使用self.吗？

谢谢

HTTPError已删除，请检查gspread更改https://github.com/burnash/gspread/blob/87583c562dd3951122411f7029963e53ef16a610/HISTORY.rst#062-2016-12-20

在这里您可以看到所有可用的例外 https://github.com/burnash/gspread/blob/master/gspread/exceptions.py

AttributeError：“模块”对象没有属性“ HTTPError”
