Google日历API在spring boot和Android中的集成

Question

我在Spring启动项目中运行Google Calendar API时遇到了一个问题。它是一个运行在live server上的企业项目

GoogleCalendarService.java

@Service
@Slf4j
public class GoogleCalenderService {

private static final List<String> SCOPES = Collections.singletonList(CalendarScopes.CALENDAR);
private static final String CREDENTIALS_FILE_PATH = "/RP_OAuth.json";
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
private static final String TOKENS_DIRECTORY_PATH = "tokens";
private static final String APPLICATION_NAME = "Google Calendar API Java Quickstart";
private GoogleAuthorizationCodeFlow flow;
private NetHttpTransport HTTP_TRANSPORT;


public String getCredentials(String candidateEmail,String recruiterEmail,long startTimeStamp, long endTimeStamp) {
    // Load client secrets.

    try {
        AuthorizationCodeRequestUrl authorizationUrl;
        authorizationUrl = getFlow().newAuthorizationUrl()
                .setRedirectUri("http://localhost:8948/Callback/"
                        +startTimeStamp+
                        "/"+endTimeStamp+
                        "/"+recruiterEmail+
                        "/"+candidateEmail
                );


        return authorizationUrl.build();

    } catch (Exception e) {
        log.error(e.getMessage());
    }

    return null;
}

public GoogleAuthorizationCodeFlow getFlow() {
    if (flow == null) {
        try {
            HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();

            InputStream in = GoogleCalenderService.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
            if (in == null) {
                throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
            }
            GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

            flow = new GoogleAuthorizationCodeFlow.Builder(
                    HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                    .setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
                    .setAccessType("offline")
                    .build();
        } catch (Exception e) {
            log.error(e.getMessage());
        }
    }

    return flow;
}

public String createCredentials(String code,long startTimeStamp, long endTimeStamp, String recruiterEmail,
                              String candidateEmail) {

    try {
        TokenResponse response = getFlow().newTokenRequest(code).setRedirectUri("http://localhost:8948/Callback/"
                +startTimeStamp+
                "/"+endTimeStamp+
                "/"+recruiterEmail+
                "/"+candidateEmail
        )
                .execute();
        Credential credential = flow.createAndStoreCredential(response, "userID");

        Calendar service = new Calendar.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
                .setApplicationName(APPLICATION_NAME)
                .build();

        Event event = new Event()
                .setSummary("You have a Scheduled Interview")
                .setDescription("Please be present on the scheduled interview date");

        DateTime startDateTime = new DateTime(startTimeStamp);
        EventDateTime start = new EventDateTime()
                .setDateTime(startDateTime);
        event.setStart(start);

        DateTime endDateTime = new DateTime(endTimeStamp);
        EventDateTime end = new EventDateTime()
                .setDateTime(endDateTime);
        event.setEnd(end);

        String[] recurrence = new String[]{"RRULE:FREQ=DAILY;COUNT=2"};
        event.setRecurrence(Arrays.asList(recurrence));

        EventAttendee[] attendees = new EventAttendee[]{
                new EventAttendee().setEmail(recruiterEmail),
                new EventAttendee().setEmail(candidateEmail),
        };
        event.setAttendees(Arrays.asList(attendees));

        EventReminder[] reminderOverrides = new EventReminder[]{
                new EventReminder().setMethod("email").setMinutes(24 * 60),
                new EventReminder().setMethod("popup").setMinutes(10),
        };
        Event.Reminders reminders = new Event.Reminders()
                .setUseDefault(false)
                .setOverrides(Arrays.asList(reminderOverrides));
        event.setReminders(reminders);

        String calendarId = "primary";
        event = service.events().insert(calendarId, event).execute();
        System.out.printf("Event created: %s\n", event.getHtmlLink());

        return event.getHtmlLink();

    } catch (IOException e) {
        log.error(e.getMessage());
        return  null;
    }

}



 }

这是我收到的错误消息

您的浏览器正在查找地址localhost:8948。如果您的浏览器没有在live server上运行，它必然会失败。您应该从请求中获取主机，并使用该主机而不是localhost，在我看来，这应该使其工作。
