public class DbxCredential
extends java.lang.Object

Use this class to store the OAuth2 result. It wraps the access token, refresh token, token expiration time as well app key and app secret, which is used for refreshing call. The object can be serialized to or deserialized from persistent storage. DbxClientV2 and DbxTeamClientV2 use this class to construct clients supporting short-live token and refresh token.

                         throws DbxException

This should be used only in internal testing. Same as refresh(DbxRequestConfig) but just add host.

Parameters:

refresh

public DbxRefreshResult refresh(DbxRequestConfig requestConfig)

Refresh the short live access token. If succeeds, the access token and expiration time value inside this object will be overwritten to new values.

Parameters:

requestConfig - request config used to make http request.

Returns:

DbxRefreshResult which contains app key and app secret.

Throws:

DbxOAuthException - If refresh failed because of invalid refresh parameter or refresh token is invalid or revoked.

DbxException - If refresh failed for general errors.

refresh

public DbxRefreshResult refresh(DbxRequestConfig requestConfig,

Parameters:

requestConfig - request config used to make http request.

scope - Must be a subset of original scopes requested with this OAuth2 grant. You can use this method to obtain a new short lived token with less access than the original one.

Returns:

DbxRefreshResult which contains app key and app secret.

Throws:

DbxOAuthException - If refresh failed because of invalid refresh parameter or refresh token is invalid or revoked.

DbxException - If refresh failed for general errors.
