Class PasswordTokenRequest (1.34.1) 

public class PasswordTokenRequest extends TokenRequest

OAuth 2.0 request for an access token using the user's username and password as specified in Resource Owner Password Credentials Grant.

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 requestAccessToken() throws IOException { try { TokenResponse response = new PasswordTokenRequest(new NetHttpTransport(), new GsonFactory(), new GenericUrl("https://server.example.com/token"), "johndoe", "A3ddj3w") .setRedirectUri("https://client.example.com/rd") .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.

Overrides

setClientAuthentication(HttpExecuteInterceptor clientAuthentication)

public PasswordTokenRequest 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

clientAuthentication com.google.api.client.http.HttpExecuteInterceptor
Returns
Type Description

setGrantType(String grantType)

public PasswordTokenRequest setGrantType(String grantType)
