问题
I have generated the following SASL string FOR OAuth 2:
user=designadmin@mydesign.mygbiz.com^Aauth=Bearer ya29.AHES6ZTtYOu0NR0vAYbrvKZNcHJPuZEpr4Hk3W3dXcXFQ88^A^A
Then i encoded it and sent the encoded string like this:
MSB AUTHENTICATE XOAUTH2 encoded string
But i get error response as:
{"status":"400","schemes":"Bearer","scope":"https://mail.google.com/"}
What does this error mean and how can i correct it?
回答1:
I finally figured it out. In my case, the Gmail scope("https://mail.google.com/") was missing, from the token generation process. It works fine now.

This can also happen if you are using an expired token. If that is the case, just re authenticate your user and use the new token.
