方法 1:
Scope defines the permissions you need to do what you need to do.
If you application needs to read from a users google drive account then you would request https://www.googleapis.com/auth/drive.readonly which grants you "read‑only access to file metadata and file content" however if you need to be able to upload to google drive you may want to ask for https://www.googleapis.com/auth/drive which grants "Full, permissive scope to access all of a user's files."
Scope defines the scope of access an application is granted.
The scope in question Plus.login https://www.googleapis.com/auth/plus.login
This is the recommended login scope providing access to social features. This scope implicitly includes the profile scope and also requests that your app be given access to: * the age range of the authenticated user * the list of circled people that the user has granted your app access to know * the methods for reading, writing and deleting app activities (moments) to Google on behalf of the user In addition, this scope enables cross‑platform single sign‑on.
方法 2:
Scopes are strings that enable access to particular resources, such as user data.
