使用Oauth2 3腿访问Gmail的基本要求

Question

What are the basic requirements (library) to access gmail using Oauth2 3 legged?

Is there any java library supported for this access?

Any kickstart example using java?

I found the example from google, but it seem like using python script to get access token. And I am getting confused.

Any inputs will be helpful.

Answer 1

There are two high level steps to access the Gmail APIs using OAuth2:

1. Obtain a user access token. To accomplish this, read this guide first, it contains the basic steps. Then, checkout the Google OAuth2 Java client library , which has convenience classes that abstract away some of the low level protocol details.

2. Use the token to authenticate w/ Gmail IMAP/SMTP and start reading mails! You already found out the relevant library in your link included in the question.
