Hola!

I am sure it is something really simple I am missing. I want to use the api but cannot get it to work as designed with local web server files (port 80). Here are some images that depict what I am experiencing. I'm on an M1 Mac Mini (Monterey) if that makes any difference.

First, I try the sample post provided on the github repo home page in postman (which works!):

Then I create a local web server (on port 80), files are accessible by a browser without specifying port:

image

Then I try the same post, except this time I point to the files on the local web server:
image

Then I tried the same post in a Notebook in Visual Studio with Python requests object:
image

Lastly, (what did work!!!) I gave the eye CLI the same arguments (local web server addresses) to the files and it worked!!

Any guidance on how to get this working as intended would be greatly appreciated!

Thanks!

Maybe the server does not work with more recent EYE versions, that would be an easy explanation.

Here on my laptop plus WSL 2 (Windows Subsystem for Linux) EyeServer still runs fine with the latest EYE v22.0409.1317

$ eyeserver 8000

@MartyStache are you using Docker or some kind of virtualization to run EyeServer?
This would explain why localhost for node (i.e. EyeServer) doesn't map to the same localhost as your cli.

Tried the same here and there is indeed an issue:
Via command line it works all fine

but via eyeserver nothing comes back

$ curl "http://localhost:8000/?data=http://localhost/eye/reasoning/socrates/socrates.n3&query=http://localhost/eye/reasoning/socrates/socrates-query.n3"

@RubenVerborgh any idea?

Oh yes, we are very likely deliberately blocking localhost access for security reasons 🙂

Yeah we are: https://github.com/RubenVerborgh/EyeServer/blob/36b3e87fd263af122c8af6ab54ea681eeaab6734/lib/eye.js#L93

Can make this into a flag.

That would be a nice option indeed!
