如何在Google日历API中使用run_flow()

Question

我正在尝试验证Google Calendar API，重复使用文档中描述的示例：

from oauth2client import file
from oauth2client import client
from oauth2client import tools
CLIENT_SECRETS = 'client_secrets.json'
FLOW = client.flow_from_clientsecrets(CLIENT_SECRETS,
                                      scope=[
                                          'https://www.googleapis.com/auth/calendar',
                                          'https://www.googleapis.com/auth/calendar.readonly',
                                      ],
                                      message=tools.message_if_missing(CLIENT_SECRETS))
storage = file.Storage('sample.dat')
credentials = storage.get()
if credentials is None or credentials.invalid:
    credentials = tools.run_flow(FLOW, storage, auth_host_name='localhost', auth_host_port=[8080, 8090],
                                 logging_level='ERROR', noauth_local_webserver=False)

此代码与一起失败

Traceback (most recent call last):
  File "C:/infoscreen/testgoogle.py", line 18, in <module>
    logging_level='ERROR', noauth_local_webserver=False)
  File "C:infoscreenoauth2clientutil.py", line 132, in positional_wrapper
    return wrapped(*args, **kwargs)
TypeError: run_flow() got an unexpected keyword argument 'auth_host_name'

run-flow()的文件表明

它假定它是从命令行应用程序运行的，并支持以下标志：

--auth_host_name：运行本地web服务器时要使用的主机名以在OAuth授权期间处理重定向。（默认值："localhost"）

我的代码出了什么问题？

Answer 1

run_flow（）函数由命令行标志控制，并且Python标准库argparse模块必须初始化，下面展示了如何使用它：

import argparse
from oauth2client import tools
from oauth2client.tools import run_flow
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.file import Storage
client_id = 'YOUR CLIENT IS HERE'
client_secret = 'YOU CLIENT SECRET IS HERE'
scope = 'https://www.googleapis.com/auth/calendar'
flow = OAuth2WebServerFlow(client_id, client_secret, scope)
parser = argparse.ArgumentParser(parents=[tools.argparser])
flags = parser.parse_args()
storage = Storage('credentials.dat')
#the get() function returns the credentials for the Storage object. 
credentials = storage.get()
if credentials is None or credentials.invalid:
  credentials = tools.run_flow(flow, storage, flags)

我迟到了一个月，但我会试一试的。

我看了一下文档，在标志部分找到了这个：

The tools module defines an ArgumentParser the already contains the flag
definitions that run() requires. You can pass that ArgumentParser to your
ArgumentParser constructor:
parser = argparse.ArgumentParser(description=__doc__,
    formatter_class=argparse.RawDescriptionHelpFormatter,
    parents=[tools.run_parser])
flags = parser.parse_args(argv)

因此，似乎不应该将标志添加为参数，而是从命令行添加它们，然后使用Google的ArgumentParser返回一个"flags"对象，然后将其添加为第三个位置参数。
