Google OAuth2身份验证和PHP上的API

Question

I have created a button that allows users to sign in with Google.

After the users choose their google accounts, I can get the following parameters as response from Google.

access tokens id_token expires_in token_type created

How can I use these parameters to use services provide from Google?

For example, can I create buttons for user to go to the gmail boxes?

If it is not the way, what are the uses of those token?

Answer 1

Using Google's tokens id you can get User's Information like Name Email.

You cant provide direct option to open Gmail. It will prompt user to login

You can refer this doc for more info Gmail scopes

Answer 2

For accessing Google services, you need the access_token . When you are creating the authentication URL, you must specify all scopes - permissions (from this list ) you want to use in your application. Then Google will ask the user for consent with delegating those permissions to your application. The access token you get will allow you to perform those actions.

You can go through those Google API scopes and get an idea what you can do and what not. For example you cannot use the GMail GUI, but you can read, send, delete, and manage user's emails, send new emails and so.
