How to make a bot to visit the site 1 time per minute?

Question

PHP

We need a bot that would just have rights on the site, and visit only one page. For example, every minute.
How is it and what is done? I'm guessing it's in Node.js, but I'm not sure.

Answer 1

You can visit a page once a minute on anything that timers and http can do. On the node including.
At the expense of rights - describe in more detail.

var links = [];
var casper = require('casper').create();

function getLinks() {
    var links = document.querySelectorAll('h3.r a');
    return Array.prototype.map.call(links, function(e) {
        return e.getAttribute('href');
    });
}

casper.start('http://google.fr/', function() {
   // Wait for the page to be loaded
   this.waitForSelector('form[action="/search"]');
});

casper.then(function() {
   // search for 'casperjs' from google form
   this.fill('form[action="/search"]', { q: 'casperjs' }, true);
});

casper.then(function() {
    // aggregate results for the 'casperjs' search
    links = this.evaluate(getLinks);
    // now search for 'phantomjs' by filling the form again
    this.fill('form[action="/search"]', { q: 'phantomjs' }, true);
});

casper.then(function() {
    // aggregate results for the 'phantomjs' search
    links = links.concat(this.evaluate(getLinks));
});

casper.run(function() {
    // echo results in some pretty fashion
    this.echo(links.length + ' links found:');
    this.echo(' - ' + links.join('\n - ')).exit();
});
