Ultimaker 3 - DIGEST AUTHENTICATION - Printing via API

[Prasanna 0]

Our aim is to achieve the printing job through a standalone java application, with the help of the API's provided by Ultimaker 3. 

 

Before performing the printing job, we need to authorize ourself by the following api's - http://ip/api/v1/auth/request and http://ip/api/v1/auth/verify.

After authorization, is printing the job using the api - http://ip/api/v1/print_job. 

 

The problem here is, it requires DIGEST AUTHENTICATION, in which a set of digest parameters to be set such as (nonce, cnonce, qop, ncount).  nonce is the instant hash provided from the server, cnonce is the instant hash set by the client. Here, able to trace all the parameters except cnonce.

While testing the same in browser, the cnonce value is set in request headers (unable to track how it has been set) and the same need to be achieved in java application.

 

Need clarification on how to create the cnonce value with the help of other available values. Thanks in advance.

You may want to use a tool like 'curl' that handles more of this for you?
