public class AuthorizationCodeFlow extends Object
Thread-safe OAuth 2.0 authorization code flow that manages and persists end-user credentials.This is designed to simplify the flow in which an end-user authorizes the application to access their protected data, and then the application has access to their data based on an access token and a refresh token to refresh that access token when it expires.
The first step is to call
loadCredential(String)
based on the known user ID to check if the end-user's credentials are already known. If not, callnewAuthorizationUrl()
and direct the end-user's browser to an authorization page. The web browser will then redirect to the redirect URL with a"code"
query parameter which can then be used to request an access token usingnewTokenRequest(String)
. Finally, usecreateAndStoreCredential(TokenResponse, String)
to store and obtain a credential for accessing protected resources.- Since:

Method Detail
-
newAuthorizationUrl
public AuthorizationCodeRequestUrl newAuthorizationUrl()
Returns a new instance of an authorization code request URL.This is a builder for an authorization web page to allow the end user to authorize the application to access their protected resources and that returns an authorization code. It uses the
getAuthorizationServerEncodedUrl()
,getClientId()
, andgetScopes()
. Sample usage:private AuthorizationCodeFlow flow; public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException { String url = flow.newAuthorizationUrl().setState("xyz") .setRedirectUri("https://client.example.com/rd").build(); response.sendRedirect(url); }
-
newTokenRequest
public AuthorizationCodeTokenRequest newTokenRequest(String authorizationCode)
Returns a new instance of an authorization code token request based on the given authorization code.This is used to make a request for an access token using the authorization code. It uses
getTransport()
,getJsonFactory()
,getTokenServerEncodedUrl()
,getClientAuthentication()
,getRequestInitializer()
, andgetScopes()
.static TokenResponse requestAccessToken(AuthorizationCodeFlow flow, String code) throws IOException, TokenResponseException { return flow.newTokenRequest(code).setRedirectUri("https://client.example.com/rd").execute(); }
- Parameters:
authorizationCode
- authorization code.
-
