test script fails on test server

[cmeesters]

Hi,

trying the script

import rdflib
from rdflib import Graph
from nanopub import Nanopub, NanopubConf, load_profile

# 1. Create the config
np_conf = NanopubConf(
    use_test_server=True,
    profile=load_profile(), # Loads the user profile that was created with `np setup`
    add_prov_generated_time=True,
    attribute_publication_to_profile=True,
)

# 2. Construct a desired assertion (a graph of RDF triples) using rdflib
my_assertion = Graph()
my_assertion.add((
    rdflib.URIRef('www.example.org/timbernerslee'),
    rdflib.RDF.type,
    rdflib.FOAF.Person
))

# 2. Make a Nanopub object with this assertion
np = Nanopub(
    conf=np_conf,
    assertion=my_assertion
)

# 3. Publish the Nanopub object
np.publish()
print(np)

fails with

Traceback (most recent call last):
  File "/home/meesters/Documents/Teaching/nanopubs_python/testnp.py", line 28, in <module>
    np.publish()

    publish_graph(self.rdf, use_server=self._conf.use_server)

requests.exceptions.HTTPError: 400 Client Error:  for url: https://np.test.knowledgepixels.com/

Note, that the example requires another import rdflib, which is missing in the README file, too.

Perhaps an issue with the testserver? @tkuhn (However, I am able to ping it and the URL displays just fine ...)

Not exactly sure what's happening here. But you should be using the branch of the Python nanopub library, which we have been working on quite a bit the last days and which now uses the new services: https://github.com/Nanopublication/nanopub-py (the changes are in an open pull request for this repo too)

Your code gives an error on this repo too, and I am not exactly sure why. I will look into it more, but these steps work fine: https://github.com/Nanopublication/nanopub-py/blob/main/examples/create_and_publish.ipynb

ok, I'll give it a try. Thank you! I think to have created a simple script easing the publication of CiTOs, but I might only find the time by next week (travelling with my family) to give this a try.

Yes, it's working, already.. Was simple enough. Needs a bit of polishing before being published, and I do not know where, yet. This repo?

PS the pyproject.toml is a bit weird and certainly needs updating too. Otherwise, poetry won't work. At least the Python version merits updating.
