java Google Oauth2刷新\u令牌为空

2 周，1 日 Questions & Answers 1490

我使用字符串执行代码请求：

https://accounts.google.com/o/oauth2/v2/auth?
   scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive.metadata.readonly&
   state={%22externalUserId%22:%22TEST%22}&
   access_type=offline&
   include_granted_scopes=true&
   redirect_uri=http://localhost:3344/oauth2/google/callbackcode&response_type=code&
   client_id=676016849609-r53vpjccpr9kf5uvuul7h6kvek1id2oh.apps.googleusercontent.com

我收到oauth2代码。我使用java客户端编写令牌请求代码

private AuthorizationCodeFlow flow;
@PostConstruct
public void init() {
    NetHttpTransport transport = null;
    try {
        transport = GoogleNetHttpTransport.newTrustedTransport();
    } catch (GeneralSecurityException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        flow = new GoogleAuthorizationCodeFlow.Builder(
                transport, JSON_FACTORY, GoogleClientSecrets.load(JSON_FACTORY,
                new InputStreamReader(GoogleCalendarClient.class.getResourceAsStream("/client_secret_676016849609-r53vpjccpr9kf5uvuul7h6kvek1id2oh.apps.googleusercontent.com.json")))
                , SCOPES).build();
    } catch (IOException e) {
        e.printStackTrace();
    }
    callBackPattern = String.format(callBackPattern, provider().lowerCaseName());
}

flow.newTokenRequest(oauthCode)
                .setRedirectUri(callBackPattern)
                .execute();

结果我收到TokenResponse

{
  "access_token": "ya29.Glv_A8Fidn8cRmQveIy0pbDIjcxssKN61X20u4zjlDYV1NbiC-QO593_isRa8Q5ngSFr-y-zICjXw1WZy4OguOh90SCyPnz0NGYpw7I4fahzH7NORQm-bbnA9Chr",

  "token_type": "Bearer"
}

没有错误，因为access_token正确。问题是TokenResponse不包含refresh_token数据

我怎样才能得到^{

Python中文网

有 Java 编程相关的问题?
