Using Digest Authentication with the Ultimaker Api in c#

[VarrickFrost 0]

Hi!

 

I am currently trying to control my Ultimaker S5 via the Api. "Get" Requests are no problem in my c# skript, however any requests that require a authentication are impossible. In Python it is quite simple, you can just use a library that does the digest authentication for you, however I spent almost a week now looking through the internet trying to get this to work in c#. Has enyone an Idea on how to approch this or has expiriance with that? Any hints would be much appreciated!

 

All best,

 

Varrick

Hi,
I am working on making a website where users upload theri gcode and then print from an avalible ultimker 3, with this code i managed to get the printer to work:
 

                        var url = "http://YOUR IP/api/v1/print_job";
                        var apiKey = "YOUR API KEY";
                        var apiSecret = "YOUR API SECRET";
                        var jobName = fileResponse.FileName;
                        var filePath = fileResponse.FullFilePath; //full file path to the file

                        using var handler = new HttpClientHandler
                        {
                            Credentials = new NetworkCredential(apiKey, apiSecret)
                        };

                        using var client = new HttpClient(handler);

                        using var fileStream = new FileStream(filePath, FileMode.Open);
                        using var content = new MultipartFormDataContent();
                        using var fileContent = new StreamContent(fileStream);

                        fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");
                        content.Add(fileContent, "file", jobName);

                        var response = await client.PostAsync(url, content);

                        if (response.IsSuccessStatusCode)
                        {
                            var responseContent = await response.Content.ReadAsStringAsync();
                            Console.WriteLine(responseContent);
                        }

I know that the post is old but I hope if anyone ever tries this again then it can come in handy.

Thanks for helping others.  Why don't you want to use digital factory?

Today I was thinking of doing something similar - I have some nest thermostats and I learned there is an API so I could make a web page that lets you see all the thermostats in all your homes all on the same screen and adjust them all from one screen and then I could have an ipad on the wall permanently...

 

Just a thought.

That is a good idea 😄

If the API is similar to what Ultimaker has to offer then it should be relatively easy 😄

What languages do you code in?
