MyCode

var async = require('async');
var request = require('request');

var array1 = ['http://www.google.com', 'http://www.amazon.com', 
'http://www.apple.com'];
var array2 = [1, 2, 3, 4, 5, 6, 7, 8, 9];

array1.each(function (item, callback) {

    console.log(item);
    aa(item, callback)

})

function aa(url) {

    request(url, function (err, res, html) {
        array2.forEach(function (item, callback) {
            //This part Current Page crawling
            console.log(item);
            sleep(1000);
        });
    })
}

how can I do that?

You have added async module but not yet used. You need to use it, you may like to use async.eachSeries() function to achieve your need. Here is code that may help you

var async = require('async');
var request = require('request');

var array1 = ['http://www.google.com', 'http://www.amazon.com', 
'http://www.apple.com'];
var array2 = [1, 2, 3, 4, 5, 6, 7, 8, 9];

function aa(url, callback) {

    request(url, function (err, res, html) {
        async.eachSeries(array2, function iteratee(item, callback2) {
            console.log(item);
            setTimeout(function() {
                callback2(null);
            }, 1000);
        }, function done() {
            callback(null)
        });
    })
}

async.eachSeries(array1, function iteratee(item, callback) {
    console.log(item);
    aa(item, callback)
}, function done() {
    console.log('completed');
});
