I have just started using Phantom/Casper.
So far I can list all the resources that a page has using this code:
casper.on('resource.received', function (resource) {
casper.echo(resource.url);
});
So far so good.
Now im trying to merge this with a chunk of code I gleaned and mashed from the documentation. I wanted to load each resource, and then print out the URL if it was missing:
casper.on('resource.received', function (resource) {
// casper.echo(resource.url);
casper.Open(resource.url, function (resource) {
this.on('http.status.404', function (resource) {
this.echo('missing:' + resource.url);
});
});
});
It's messy, but it's what I've got. It fails to open the resources (ln 3), and the console shows no activity.
How can I rewrite this to iterate over the resources and check them for 404s?
(I am aware in my example that I'm not iterating over the resources, I was tempted to use eachthen(), but It's not clear if I can use general casperJS methods inside the 'test' prototype. Sorry, I hope this wasn't too long)
CasperJS' resource.received
is based on PhantomJS' onResourceReceived
. As you can see from the documentation, you can simply access resource.status
. There is no need to explicitly load the resource.
casper.on('resource.received', function (resource) {
if (resource.stage === "end" && resource.status === 404) {
this.echo('missing:' + resource.url);
};
});
Btw, you probably mean casper.open
and not casper.Open
.
