B4J Question httpUtils handle the onload event (sso server) [SOLVED]

mc73 · Jul 20, 2016

I have a problem with a website, for which I intend to download some pdf files without the need to use a browser.

I download the main web page, then I request another one (cause their system is not allowing direct access without first opening the main page), and then comes a page which includes a <BODY onLoad=document.SingleSignOn.submit();>
Now, since the onLoad is not working, I'm posting to the action-url all the hidden variables.
Unfortunately, I get an error page saying that this is a single sign on server, instead of getting me to the login page.
I'm wondering where the problem might be, any help would be appreciated.

HttpUtils2 sends http requests and returns the server response. It doesn't do anything with the response and specifically it doesn't run any JavaScript.

You need to use a tool such as FireBug to understand the flow expected by the server.

The problem is that I followed the flow until the point at which, as described, a submit onLoad is fired. Though I'm posting the variables as found in the source, I get a clown of the page. Anyway, most probably, there is indeed another step inside the flow which I didn't notice in fireBug, I'll try to see what that is, thank you.

After some time dealing with this, it came out that the problem was that at some point I had to set the referer to the headers of the request and that solved the issue
