Question

我在一个小应用程序中结合了Dropbox和google驱动器，允许你选择一个Dropbox文件并将其上传到google驱动器但是我每次使用这个应用程序时都要复制两次授权码，这不是很舒服，如何在每次使用时都避免使用或获取授权码？

flow = dropbox.client.DropboxOAuth2FlowNoRedirect(app_key, app_secret)

#parte dropbox
authorize_url = flow.start()
print '1. Go to: ' + authorize_url
print '2. Click "Allow" (you might have to log in first)'
print '3. Copy the authorization code.'
code = raw_input("Enter the authorization code here: ").strip()

access_token, user_id = flow.finish(code)
client = dropbox.client.DropboxClient(access_token)

Google和Dropbox之间的故事有所不同。我对Dropbox方面更有信心（因为我在那里工作）：

对于Dropbox，一旦您获得了访问令牌，您就可以无限期地重复使用它。因此，一旦执行access_token, user_id = flow.finish(code)，您就可以保存access_token并在同一用户想要使用该应用时重复使用它。（只需使用保存的令牌client = dropbox.client.DropboxClient(access_token)。）
对于Google，访问令牌会在一段时间后过期，因此您需要使用刷新令牌来获取新令牌。因此，最好的办法是同时保存（访问令牌和刷新令牌），如果尚未过期则直接重用访问令牌，或者如果访问权限，则使用刷新令牌获取新的访问令牌令牌已经过期。我担心我不太了解Google的图书馆，以便更多地了解它。
