loop through array of urls in phantomjs using javascript

问题

I'm trying to get my code to loop through an array of urls but getting stuck.

This bit of code simply runs in phantomjs and outputs the requested url and the redirects for any main resource objects.

I'd like to use an array as an input to this process like:

var pageUrl = [
'http://www.google.com',
'http://www.facebook.com'
];

here's the original

var sys = require('system');
var pageUrl = 'http://www.google.com';


console.log("Requested URL: " + pageUrl);



var renderPage = function (url) {
    var page = require('webpage').create();

    page.onNavigationRequested = function(url, type, willNavigate, main) {

        if (main && url!=pageUrl) {
            console.log("Redirected URL: " + url)
        }
    };



    page.open(url, function(status) {
            if ( status !== 'success' ) {
                phantom.exit(1);
            } else {
                setTimeout(function() {
                    phantom.exit(0);
                }, 0);
            }
        });
};


renderPage(pageUrl);

回答1:

var urls = [
'http://www.google.com',
'http://www.facebook.com'
];


function process() {
    if (urls.length == 0) {
        phantom.exit();
    } else {
        //remove the first item of an array
        url = urls.shift();
        //open a page
        page = require('webpage').create();

        //store the requested url in a separate variable
        var currentUrl = url


        page.open(url, onFinishedLoading)

        page.onNavigationRequested = function(url, type, willNavigate, main) {
            console.log('\n' + currentUrl + '\nredirecting to \n' + url);
        }

    }
}

function onFinishedLoading(status) {

    console.log(status);
    page.release();
    process();
}

process();
