使用 Gmail 创建桌面应用程序 API

Question

我一直在尝试配置我的 conky 以显示我的 Gmail 帐户中未读邮件的详细信息。我终于想出了一个 python 脚本来完成这个任务。它使用我从 google 开发者控制台下载的 client_secret.json 文件。这是代码

from datetime import datetime
import os

from oauth2client import tools

try:
    import argparse
    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None
SCOPES = 'https://www.googleapis.com/auth/gmail.readonly'
CLIENT_SECRET_FILE = 'client_secret.json'
APPLICATION_NAME = 'Gmail Notifier'

def get_credentials():
    """Gets valid user credentials from storage.

    the OAuth2 flow is completed to obtain the new credentials.

    home_dir = os.path.expanduser('~')
    credential_dir = os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):
        os.makedirs(credential_dir)
    credential_path = os.path.join(credential_dir, 'gmail-notifier.json')
    store = oauth2client.file.Storage(credential_path)
    credentials = store.get()
    if not credentials or credentials.invalid:
        flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent = APPLICATION_NAME
        if flags:
            credentials = tools.run_flow(flow, store, flags)
        else: # Needed only for compatability with Python 2.6
            credentials = tools.run(flow, store)
        print 'Storing credentials to ' + credential_path
    return credentials

现在我想把它做成一个合适的应用程序，这样它就可以共享，用户不需要去 google 开发者控制台来获取 .json 文件。

如果我通过应用程序分发 .json 可以吗？

如果是这样，我就完成了，如果不是，那么

将此脚本制作成桌面应用程序的正确方法是什么？

我查看了开发人员控制台中的各种选项，但无法弄清楚如何制作桌面应用程序。我对 google 开发人员和 API 完全陌生，所以任何帮助将不胜感激。

Answer 1

我也是这个 API 的新手，正在尝试弄清楚同样的事情。我认为分发带有机密的 .json 文件不是一个好主意。

至少我在 docs "Keep your client secret private. If someone obtains your client secret, they could use it to consume your quota, incur charges against your Console project, and request access to user data."
