Problem downloading file from FMS Container field – Session key Cookie

masterkey Jul 19, 2017 6:25 AM

It was a positive surprise to be able to get the url of the content of a container field by api call wich can be used in the script step «insert from url».

The usage of that url with a web browser works fine – the file is being downloaded and it can be opened and used without problem.

If using the url to insert from url, the content of the target container cannot be opened or used.

It seems, the file gets corrupted.

Has anyone made similar experiences or knows anything about this problem?

Are there additional curl settings needed?

Did really nobody use this feature yet!?
Inserting a file from FileMaker Server to a Container field while getting the url from the server by api call.
Actually I am not sure it really is a feature because it seems to be difficult to make it work.

Can you provide some more detail? What API? What file type? I've used dropbox and box.com APIs to insert files without any issues.

Its on a FMDB-File in a Container field on a FM Server 16.
From FMP 16 client I ask by api call (FileMaker) for the downloadlink of a container field.
This url I use as URL for insert from url.

I found out, that the missed info is the X-FMS-Session-Key cookie.
Any idea how to get it?

Thank you.

A little more information required:

Through the XML API? PHP API?

Sorry, what a question, the new REST API of course!

The problem should not be related to that question – FMS sends back an url (in a JSON string).
This string can be used with Safari on Mac or with Mac Paw to get the File.
Just FileMaker cannot because of authentication problems.

Just trying to help... the question is relevant because of the different ways that FM can maintain a session. Especially since you think a session cookie is in play.

Thank you for that!

I used Mac Paw with the url I got from FMS.
The cookie option "Automatically send cookies" is checked.
In the request headers I found an entry "Cookie: X-FMS-Session-Key=37372378608972...".

When I just copy this string and put it into curl-options as "-H \"Cookie: X-FMS-Session-Key=37372378608972...\"", everything works great.
So the question is, can curl also do anything like "automatically send cookies" or how to get and then send back the session-key-cookie to FMS?

What I really do not understand, this is all FileMaker – why this is not described somewhere in a manual!?
Even the technical possibilities of FileMaker are getting better, the support is just terrible.

It is possible and works great – just set the correct curl options.
