How to copy entire sheets from google spreadsheet

问题:

Hi I am using googleapis npm package for work with spreadsheet. I have a function which use to copy spreadsheet but problem is that it only copy one sheet however my source spreadsheet has mupltiple sheets.

Here is my code:-

const { google } = require('googleapis');
var sheet_id = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx';
..
..
..

function copySpreadSheet(authClient, sheet_id) {
console.log('sheet_id', sheet_id)
const sheets = google.sheets({ version: 'v4', authClient });


sheets.spreadsheets.create({
    auth: authClient,
    resource: {
        properties: {
            title: "New Sheet " + new Date()
        }
    }
}, (err, response) => {
    if (err) {
        console.log('The API returned an error: ' + err);
        return;
    } else {
        console.log(response.data)
        var request = {
            spreadsheetId: sheet_id, 

            sheetId: 0,  // HERE I SOMETHING MISSING

            resource: {
                destinationSpreadsheetId: response.data.spreadsheetId
            },
            auth: authClient,
        };


        sheets.spreadsheets.sheets.copyTo(request, function (err, response2) {
            if (err) {
                console.error(err);
                return;
            }
            console.log(response2.data);
        });

        console.log("Added");
    }
});

}
