UM 5 API help

[mmittlem 1]

Hello!

 

I am new to API software and am working on a research project where I need to send gcode to my printer using python. I only have experience with an Ender and using a serial port to do this, so the API world and wireless communication is all new to me. 

 

I've gotten an ethernet connection setup on the printer an am attempting to follow the Swagger documentation to start authentication, hoping this will eventually allow me to use the requests python library to send the gcode I want. But I'm stuck on one of the first few steps. 

 

To request authentication, the docs say to input this into a web browser: http://<my_printer_ip>/api/v1/auth/request or use the same curl command with the application and user params. In the web browser, i get this error: 

{"message":"405 Method Not Allowed: The method is not allowed for the requested URL."}

And using the following curl command: curl -X POST --header 'Content-Type: multipart/form-data' --header 'Accept: application/json' -F application=test' -F user=mmittlem  'http://<my_printer_ip>/api/v1/auth/request'

 

i get these errors

curl: (28) Failed to connect to multipart port 80 after 22087 ms: Couldn't connect to server
curl: (28) Failed to connect to application port 80 after 22076 ms: Couldn't connect to server
curl: (3) URL rejected: Port number was not a decimal number between 0 and 65535

 

I'm using a placeholder for the application, since I am unsure quite what that parameter is. That could very well be the source of the issue—i just don't have enough experience to know otherwise. 

 

I've tried a few other things but nothing appears to be working. The documentation on the auth/check requires an id for it to work, and giving that the id from the 'response body' section of the request (despite being unable to actually fetch an id on my own computer), i do get the "authorized" message. But none of the other commands are working. 

 

If anyone can offer any general or specific advice, that would be greatly appreciated! Even just a document out there on how to setup the API would be fantastic, or some resource I can refer to. Thank you!

Hiya! Firstly just so you know, I'm moving this to the "Third party products and modifications" board since this really doesn't have anything to do with Cura.

 

The only thing I can think of off the top of my head is have you tried using https instead of http?

 

A community about... Swagger, was it you said? would probably be a much better place to ask about something like this.

Obvious question, did you replace <my_printer_ip> with the IP address of the printer? If not, that’s the problem. 

[mmittlem 1]

Yes, I tried both http and https. And yeah, the <my_printer_id> is the ip of my printer, i just didn't want to include it in a public post. 

 

I can look around for a help forum for the API hosting site!
