Class RefreshTokenRequest (1.34.1) 

public class RefreshTokenRequest extends TokenRequest

OAuth 2.0 request to refresh an access token using a refresh token as specified in Refreshing an Access Token.

Use Credential to access protected resources from the resource server using the TokenResponse returned by #execute(). On error, it will instead throw TokenResponseException.

Sample usage:

static void refreshAccessToken() throws IOException { try { TokenResponse response = new RefreshTokenRequest(new NetHttpTransport(), new GsonFactory(), new GenericUrl( "https://server.example.com/token"), "tGzv3JOkF0XG5Qx2TlKWIA") .setClientAuthentication( new BasicAuthentication("s6BhdRkqt3", "7Fjfp0ZBr1KtDRbnfVdmIw")).execute(); System.out.println("Access token: " + response.getAccessToken()); } catch (TokenResponseException e) { if (e.getDetails() != null) { System.err.println("Error: " + e.getDetails().getError()); if (e.getDetails().getErrorDescription() != null) { System.err.println(e.getDetails().getErrorDescription()); } if (e.getDetails().getErrorUri() != null) { System.err.println(e.getDetails().getErrorUri()); } } else { System.err.println(e.getMessage()); } } }

Some OAuth 2.0 providers don't support BasicAuthentication but instead support ClientParametersAuthentication. In the above sample code, simply replace the class name and it will work the same way.

Implementation is not thread-safe.

Methods

getRefreshToken()

public final String getRefreshToken()

Returns the refresh token issued to the client.

Type Description
String

set(String fieldName, Object value)

Parameters
Name Description
fieldName String
value Object
Returns
Type Description
RefreshTokenRequest
Overrides

setClientAuthentication(HttpExecuteInterceptor clientAuthentication)

public RefreshTokenRequest setClientAuthentication(HttpExecuteInterceptor clientAuthentication)

Sets the client authentication or null for none.

The recommended initializer by the specification is BasicAuthentication. All authorization servers must support that. A common alternative is ClientParametersAuthentication. An alternative client authentication method may be provided that implements HttpRequestInitializer.

This HTTP request execute interceptor is guaranteed to be the last execute interceptor before the request is executed, and after any execute interceptor set by the #getRequestInitializer().

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

Parameter
Name Description
clientAuthentication com.google.api.client.http.HttpExecuteInterceptor
Returns
Type Description
RefreshTokenRequest
Overrides

setGrantType(String grantType)

public RefreshTokenRequest setGrantType(String grantType)

Sets the grant type ("authorization_code", "password", "client_credentials", "refresh_token" or absolute URI of the extension grant type).

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.
