如何在不使用OAuth 2.0的情况下使用Google Calendar API

Question

I wanted to know if there is any way to use google calendar api without using OAuth. For example only to write in my public calendar from a web application in Net Beans. I just need to write to my calendars, not in other people's calendars. Try using Aouth 2.0 but did not work.

Answer 1

Except for displaying a public calendar, you'll always need authorization to perform operations on the Calendar API. If you check the events.insert page, you'll see immediately that this requires Authorization. Even using service accounts which bypasses the manual authorization, uses OAuth.

Answer 2

I am using java in netbeans. my application is a type of web service, I return some json using jsp. jsp call the function that returns my upcoming events on my calendar. but when I try to authorize nothing happens. this is my code. (I have all the necessary libraries).

  public static Credential authorize() throws IOException {
    Credential credential;

    try {

        GoogleClientSecrets clientSecrets = new GoogleClientSecrets();
        GoogleClientSecrets.Details det = new GoogleClientSecrets.Details();
        det.setClientId("my id");
        det.setClientSecret("my secret");
        det.setRedirectUris(Arrays.asList("urn:ietf:wg:oauth:2.0:oob"));
        clientSecrets.setInstalled(det);

        GoogleAuthorizationCodeFlow flow =  new      GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(DATA_STORE_FACTORY)
                .setAccessType("offline")
                .build();
        credential = new AuthorizationCodeInstalledApp(flow, new                                                  LocalServerReceiver()).authorize("user");

    } catch (Exception ex) {
        credential = null;
    }

    return credential;
}
