Explore Neuroglancer URIs

[frcroth]

URL of deployed dev instance (used for testing):

• https://___.webknossos.xyz

Steps to test:

• Open a dataset in Neuroglancer and copy the URL to "Add remote dataset", e.g. this

TODOs:

• Respect credentials --> Fail on credentials
• Test it for different datasets with Neuroglancer (esp. N5 and Zarr)
  • N5 fibsem-uint16
  • Zarr 610024
• Needs to be refactored after Allow uploading zarr datasets #7397 is merged

Note: Some of the examples at neuroglancer can't be imported because they use URIs that are not standard-compliant, which causes an exception in the java.net.URI implementation. Specifically, that is because there are multiple number signs (#), where only one is allowed. For example, this fails.

Issues:

• fixes Explore/Import from Neuroglancer URI #7385

Looking good :)

I tried with some examples from here https://github.com/google/neuroglancer#examples but always got Received invalid URI in the explore report. Maybe it has something to do with url encoding? I have a l ot of %7B%22 in the uris. Can you reproduce that? (I clicked open viewer, waited till the neuroglancer page is loaded, then copied the uri from the firefox address bar)

Alright, looks like that was in fact an illegal URI (double hash sign). I’d say it’s fair that we can’t take those for the moment.
