こんにちは皆さん、これはカレンダーを変更するためにGoogleアカウントに接続するための私のコードですが、システムが「無許可」と応答するたびに。accessTokenが検証されていないように、どこに問題があるのか​​わかりません

よろしくお願いします

最新バージョンのJavaAPIライブラリでは、OAuthを処理するためのメカニズムが大幅に変更されています。

ここのサンプルコードで参照されているビルダーパターンに従う必要があります： http ：//code.google.com/p/google-api-java-client/source/browse/calendar-cmdline-sample/src/main/ java / com / google / api / services / samples / calendar / cmdline / CalendarSample.java？repo = samples＃57

Credential credential = OAuth2Native.authorize(
    HTTP_TRANSPORT, JSON_FACTORY, new LocalServerReceiver(),
    Arrays.asList(CalendarScopes.CALENDAR));

// set up global Calendar instance
client = com.google.api.services.calendar.Calendar.builder(HTTP_TRANSPORT, JSON_FACTORY)
    .setApplicationName("Google-CalendarSample/1.0").setHttpRequestInitializer(credential)
    .build();

これにより、プロンプトが自動的に処理されます（さらに、デスクトップでブラウザを開くためのすばらしい魔法も実行されます）。または、これを裏で行う方法を探している場合は、詳細についてはこちらをご覧ください： http ://code.google.com/p/google-api-java-client/source/browse/shared/shared-sample -cmdline / src / main / java / com / google / api / services / samples / shared / cmdline / oauth2 / OAuth2Native.java？repo = samples＃102

オブジェクトを設定した後GoogleAccessProtectedResource、それをCalendarサービスクラスに正しく渡していない。

これを変える：

com.google.api.services.calendar.Calendar service = 
    new com.google.api.services.calendar.Calendar(httpTransport,
                                                  jsonFactory);

これに：

com.google.api.services.calendar.Calendar service = 
    new com.google.api.services.calendar.Calendar(httpTransport, 
                                                  accessProtectedResource, 
                                                  jsonFactory);

それはそれをする必要があります。
