Alfresco Update File - ERROR POST

Question

I\'m trying to update a file in Alfresco... And I make this code:

var csrf_header = Alfresco.util.CSRFPolicy.getHeader();
var csrf_token = Alfresco.util.CSRFPoli         


        

Answer 1

Instead of setting the header, pass the token on the url:

if (Alfresco.util.CSRFPolicy && Alfresco.util.CSRFPolicy.isFilterEnabled())
{
   url += "?" + Alfresco.util.CSRFPolicy.getParameter() + "=" + encodeURIComponent(Alfresco.util.CSRFPolicy.getToken());
}

As described in CSRF Policy

When uploading a file by submitting a form with enctype multipart/form-data it is not possible to set a header on the request, the reason is not because of the enctype specifically but due to the fact that its not possible to set a header on any form submission in the browser.

The other solution is to use Alfresco.forms.Form that takes care of everything.

Answer 2

Try moving these lines inside your function:

var csrf_header = Alfresco.util.CSRFPolicy.getHeader();
var csrf_token = Alfresco.util.CSRFPolicy.getToken();

And if that does not solve your problem and the issue turn out to be not a matter of variable scope for csrf_* vars, then you should try hint (2) from here

UPDATE : As I explained in our chat you should replace :

fd.append("filedata", pdfbase64);

with :

fd.append("filedata", new Blob([pdfbase64], {type: 'application/pdf'}););
