코드 만들기

var startDate = "2018-01-01";                       
var endDate = "2018-04-01";

var jwtClient = new google.auth.JWT(credential.client_email, null, credential.private_key, ["https://www.googleapis.com/auth/analytics.readonly"], null);

    if (error) {
        console.log(error);
        return;
    }
    analytics.reports.batchGet({
        resource: {
