Publish app with QRS API gives XSRF error

[#1]

Hello,

I tried to write a simple .NET method to publish an existing app to a stream. The path that I used with QRS API is as below:

qrs/app/ee227e84-a2b0-4ba7-b9ec-9fe3d1718308/publish?stream=6f287d6f-3e6f-4a5e-9857-3d800e99da28?xrfkey=0123456789abcdef

However, it keeps giving me XSRF error ("XSRF prevention check failed. Possible XSRF discovered.") no matter I tested with Postman or from my own code, both of which I included the Header "X-Qlik-Xrfkey" with the same value 0123456789abcdef

I have a lot of other Qs API calls that used the same testing mechanism, but they all passed.

Is there anything wrong with my query above?

Thanks a lot!

Indeed, there is one typo that causes this failure.

You use two times the ? question mark. The second should become an &, right?:

qrs/app/ee227e84-a2b0-4ba7-b9ec-9fe3d1718308/publish?stream=6f287d6f-3e6f-4a5e-9857-3d800e99da28&xrfkey=0123456789abcdef

Cheers,

Hi Friebel,

Thanks a lot for your help! It is working perfectly.

I used 2 question marks because the reference here used a question mark before "stream".

Please bear with me if this is a silly question, but it has been on my mind for a while.

When shall I use question mark and when shall I use & sign in a query?

Thanks again!

The query is separated by the ? from the path. Inside a query can be numerous key=value-pairs which are separated by &. That's basically it.

I strongly suggest you take some time to get deeper into the HTTP-thing as you will have to deal with it more often when using the REST apis. Maybe start here: http://code.tutsplus.com/tutorials/http-the-protocol-every-web-developer-must-know-part-1--net-31177
