UUID的Base 64编码-用作访问令牌

Question

I am writing a GoLang Oauth application in which I am using below method to generate a UUID and then generate accessToken from the UUID.

import "github.com/pborman/uuid"
uuid := uuid.NewRandom()
accessToken = base64.RawURLEncoding.EncodeToString([]byte(uuid)) 

Wanted to know the base64 encoding of a token is as unique as UUID or not because accessToken will have unique index in my MYSQL db and will fail if there is a collision.

Answer 1

Yes it's unique because your uuid is unique. Why don't you use uuid as token ? There is no need to base64 it you can use that as is.
