新しいCalendarAPIv3を使用してカレンダーイベントを一覧表示したい。その記事（Calendar API v3、2本足のOAuthとJava）を読み、同じ方法で認証を行いました。私の工場を見てください：
import java.io.IOException;
import com.gene.herder.google.GoogleApiSettings;
import com.google.api.client.auth.oauth.OAuthHmacSigner;
import com.google.api.client.auth.oauth.OAuthParameters;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.calendar.Calendar;
import com.google.api.services.calendar.Calendar.Builder;
import com.google.api.services.calendar.CalendarRequest;
import com.google.api.services.calendar.CalendarRequestInitializer;
public final class CalendarApiFactory {
private GoogleApiSettings settings;
public CalendarApi createCalendarApi() {
Calendar calendar = createBuilder(settings).build();
CalendarApi calendarApi = new CalendarApi();
calendarApi.setCalendar(calendar);
return calendarApi;
}
private Builder createBuilder(GoogleApiSettings settings) {
HttpTransport transport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
OAuthParameters oauthParameters = createOAuthParameters(settings);
Builder builder = new Builder(transport, jsonFactory, oauthParameters);
builder.setApplicationName("MY-COMPANY-MY-APP/1.0");
builder.setCalendarRequestInitializer(new SettingsCalendarRequestInitializer(settings));
return builder;
}
private OAuthParameters createOAuthParameters(GoogleApiSettings settings) {
OAuthParameters oauthParameters = new OAuthParameters();
oauthParameters.version = "1";
oauthParameters.consumerKey = settings.getClientKey();
oauthParameters.signer = createSigner(settings);
return oauthParameters;
}
private OAuthHmacSigner createSigner(GoogleApiSettings settings) {
OAuthHmacSigner signer = new OAuthHmacSigner();
signer.clientSharedSecret = settings.getClientSecret();
return signer;
}
public void setSettings(GoogleApiSettings settings) {
this.settings = settings;
}
}
class SettingsCalendarRequestInitializer extends CalendarRequestInitializer {
private GoogleApiSettings settings;
public SettingsCalendarRequestInitializer(GoogleApiSettings settings) {
this.settings = settings;
}
@Override
protected void initializeCalendarRequest(CalendarRequest<?> request) throws IOException {
request.setKey(settings.getApiKey());
}
}
その後、私はこのように実装CalendarApiしました：
import java.io.IOException;
import com.google.api.client.util.ArrayMap;
import com.google.api.services.calendar.Calendar;
import com.google.api.services.calendar.Calendar.Events.Insert;
import com.google.api.services.calendar.Calendar.Events.List;
import com.google.api.services.calendar.model.Event;
import com.google.api.services.calendar.model.Events;
public class CalendarApi {
private Calendar calendar;
public Events listEvents(String calendarId) throws IOException {
// Add the xoauth_requestor_id query parameter to let the API know
// on behalf of which user the request is being made.
ArrayMap<String, Object> customKeys = new ArrayMap<String, Object>();
customKeys.add("xoauth_requestor_id", calendarId);
List events = calendar.events().list("primary");
events.setUnknownKeys(customKeys);
return events.execute();
}
public void setCalendar(Calendar calendar) {
this.calendar = calendar;
}
}
私のドメイン構成は次のようになります：
高度なツール=>サードパーティのOAuthクライアントアクセスを管理する
私のコンソールAPIは次のようになります。
listEventsここで、「user1@my-company-domain.com」パラメーターを使用してメソッドを呼び出すと、すべて正常に機能します。指定したカレンダーのすべてのイベントを見ることができます。
しかし、他のドメインユーザーを渡すと、常に「無効な資格情報」の例外が発生します。スタックトレース：

私のMavenの依存関係は次のようになります。

なぜそれが機能しないのですか？そのAPIは、好きなユーザーに使用できると思いました。どこを間違えたの？
