Question

我正在尝试对使用the sample described in the docs的Google Calendar API进行身份验证：

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)

此代码以

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:\infoscreen\oauth2client\util.py", line 132, in positional_wrapper
    return wrapped(*args, **kwargs)
TypeError: run_flow() got an unexpected keyword argument 'auth_host_name'

documentation for run-flow()说

它假定它是从命令行应用程序运行并支持   以下标志：

- auth_host_name：运行本地Web服务器时使用的主机名       在OAuth授权期间处理重定向。       （默认：'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，必须初始化Python标准库argparse模块，以下显示如何使用它：

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。

我查看了文档，并在标记部分下找到了这个：

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)

所以好像你不应该将标志作为参数添加，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

如何在Google Calendar API中使用run_flow（）？
