How retrieve the content of the last page opened with CasperJS?

The call to this.getPageContent() doesn't retrieve the content of the last page opened.

How retrieve the content of the last page opened ? 

var casper = require("casper").create({
    verbose: true,
    logLevel: "debug",
    waitTimeout: 10000,
    retryTimeout: 1000
});


casper.start(function() {
    this.open('http://example.com/contentTypes', {
        method: 'get',
        headers: {'Accept': 'application/json'}
    });
    console.log(this.getCurrentUrl());
});

casper.then(function() {
    // get content of http://example.com/contentTypes << OK
    var ressources_type = JSON.parse(this.getPageContent());
    require('utils').dump(ressources_type);

    for (var i in ressources_type.data) {
        this.thenOpen('http://example.com/ressource?type=' + ressources_type['data'][i]['key'] , {
            method: 'get',
            headers: { 'Accept': 'application/json'}
        });

        // get content of http://example.com/contentTypes instead of http://example.com/ressource?type=' + ressources_type['data'][i]['key']
        var ressources = JSON.parse(this.getPageContent());
        require('utils').dump(ressources);

        for (var j in ressources['data']) {
            ...
        }

    }
});


casper.run(function() {
    this.echo('Done.').exit();
});

CasperJS is asynchronous in nature. Every then* and wait* call (step functions) schedules the passed function, but doesn't execute it immediately. You are mixing asynchronous calls (thenOpen) with synchronous calls (getPageContent).

You need to move every synchronous call into a step function.

this.thenOpen('http://example.com/ressource?type=' + ressources_type['data'][i]['key'] , {
    method: 'get',
    headers: { 'Accept': 'application/json'}
});
this.then(function(){
    var ressources = JSON.parse(this.getPageContent());
    require('utils').dump(ressources);

    for (var j in ressources['data']) {
        ...
    }
});
