casperjs doesn't work as expected on windows machine

Question

I have a casperjs script which gives the desired result when I run on a linux server, but when I run the same from my laptop, it doesn't work.

How should I debug? Logs of the working one:

Script:

var casper = require('casper').create ({
  waitTimeout: 60000,
  stepTimeout: 60000,
  verbose: true,
  logLevel: "debug",
  viewportSize: {
    width: 1366,
    height: 768
  },
  pageSettings: {
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0",
    "loadImages": true,
    "loadPlugins": true,
    "webSecurityEnabled": false,
    "ignoreSslErrors": true
  },
  onWaitTimeout: function() {
    casper.echo('Wait TimeOut Occured');
  },
  onStepTimeout: function() {
    casper.echo('Step TimeOut Occured');
  }
});

casper.start('http://caspertest.grsrv.com/', function() {
    this.fillSelectors('form', {
        'input[id="userName"]': 'test',
        'input[id="userPassword"]': 'test',
    }, false);
    this.capture('ss.png');
    this.click('input[id="loginButton"]')
});


casper.waitForSelector('#aggr_actionAccept', function() {
    this.click('input[id="aggr_actionAccept"]')
});

This is how I am executing:

casperjs --ignore-ssl-errors=true test.js

The resource is with a client and I am using a VPN on my windows machine to access the resource on my browser. The linux machine on which it is working is with the client itself

How about add this.echo(this.getHTML()); this.capture('before_fill.png'); immediately before this.fillSelectors - maybe the page looks different or doesn't load as quickly from the windows box? – Pimp

<html><head></head><body></body></html> is the response of this.getHtML(). How can I check with what options casperjs is running? I want to know if it really ignores ssl errors or not. This is important to know because when I access with my browser it gives ssl certificate issue. Sorry for late reply. – Mazzard

Yes, I am using that option. I have mentioned it in my question. – Mazzard

Answer 1

Add a resource.error event handler:

casper.on("resource.error", function(resourceError){
    console.log('Unable to load resource (#' + resourceError.id + 'URL:' + resourceError.url + ')');
    console.log('Error code: ' + resourceError.errorCode + '. Description: ' + resourceError.errorString);
});

It seems, this is a known PhantomJS bug (Fixed in 2.5 beta).
You can download PhantomJS 2.5 beta from this page.

You need to add the following callbacks, to catch all the errors:

casper
.on("error", function(msg){ this.echo("error: " + msg, "ERROR") })
.on("page.error", function(msg, trace){ this.echo("Page Error: " + msg, "ERROR") })
.on("remote.message", function(msg){ this.echo("Info: " + msg, "INFO") });

As i can see from the log, something is going wrong at the time of submitting a form, it seems, CasperJS can't redirect you to the target page. – Unhappy

Hi, I ran with --cookies-file command-line option, no cookie file was generated. And why you asked to try twice? fillSelectors() is working fine on linux machine. Yes, it isn't getting redirected to the target page, and if it gets redirected the page doesn't load rendering just <html><head></head><body></body></html>. – Mazzard

Here i had a similar problem with auth, i just used --cookies-file option in that case, see this issue -There was redirecting into an empty page, like in your case. – Unhappy

Have you tried to get screenshot ss.png without submitting a form? – Unhappy

Have you tried to log in, by using usual browser, e.g. Google Chrome? – Unhappy

Yes, I have tried get screenshot without submitting a form, I get a blank page. So I printed the html, i got <html><head></head><body></body></html>. On usual browser, I get a security error, which I ignore, and then I am able to login properly. – Mazzard

Earlier I was having waitTimeout and stepTimeout of 60 seconds, I later tried with 120 seconds as well. No gain. I added the callbacks that you mentioned, I did not get anything except : error: CasperError: Errors encountered while filling form: form not found – Mazzard

i've updated the answer, can't wait for your results! I hope, we can solve the problem! – Unhappy

Sorry, I couldn't check because it was a weekend. I'll update my findings in a few minutes. btw, I have already tried --ssl-protocol=any --ignore-ssl-errors=true – Mazzard

it still didn't work, but your event handler gave the reason Error code: 6. Description: SSL handshake failed; ideally, --ssl-protocol=any should solve it but doesn't for me. phantomjs --version :2.1.1, casperjs --version : 1.1.0-beta5 – Mazzard

It didn't work :(, still got Error code: 6. Description: SSL handshake failed. This is expected since --ssl-protocol=any didn't work. I really feel casper or phantom is ignoring this option. Thank you igor for being with me on this. :) – Mazzard

It works. Thank you so much. :) I had searched a lot, but this never come up in my search results. – Mazzard
