问题
I'm creating a Chrome extension that modifies the gmail UI. But when I authenticate (with chrome.identity.getAuthToken) in the Chrome extension, it defaults to using the user account that is signed into Chrome.
But I need data for a gmail account when I am on that gmail page.
I saw this answer, but I was wondering if there was any easier way?

I just went through the same process and I couldn't find an easier way.
You'll need to authenticate yourself.
We tried using the mechanism in that link but it requires putting the Client Secret in the Extension - very ugly.
In the end we request and refresh tokens externally through a hosted web page from our www site.
Although a hassle to set up once in place it works nicely and is worth the effort.
