Methods
Request an access token
Use xoauth2obj.getToken(callback)
to get an access token. If a cached token is found and it should not be expired yet, the cached value will be used.
Request for generating a new access token
Use xoauth2obj.generateToken(callback)
to get an access token. Cache will not be used and a new token is generated.
Update access token values
Use xoauth2obj.updateToken(accessToken, timeout)
to set the new value for the xoauth2 access token. This function emits 'token'
Events
If a new token value has been set, 'token'
event is emitted.
xoauth2obj.on("token", function(token){
console.log("User: ", token.user); // e-mail address
console.log("New access token: ", token.accessToken);
console.log("New access token timeout: ", token.timeout); // TTL in seconds
});
