Potential bug/Unspecified behaviour

Let's look at a template like this:

http://example.com/dictionary/{term:1}

We have two different behaviours depending upon the value used to expand term.

>>> import uritemplate
>>> u = uritemplate.URITemplate('http://example.com/dictionary/{term:1}')
>>> u.expand(term='foo')
'http://example.com/dictionary/f'
>>> u.expand(term=['foo', 'bar', 'bogus'])
'http://example.com/dictionary/foo,bar,bogus'

A simplified version of this is simply

{term:1}

In other words:

>>> import uritemplate
>>> u = uritemplate.URITemplate('{term:1}')
>>> u.expand(term='foo')
'f'
>>> u.expand(term=['foo', 'bar', 'bogus'])
'foo,bar,bogus'

All versions of uritemplate (and uritemplate.py) exhibit this behaviour and the RFC does not provide clear guidance.

I have not investigated how other implementations in other languages handle this, though. There do not appear to be any examples in the RFC that combine lists with length limitations.

Inizia con gli esempi di URITemplate.expand nell’issue e con le regole del modificatore di prefisso di RFC 6570, quindi confronta l’espansione dei valori scalari e delle liste. L’issue non indica file del repository né un test esistente; il completamento dovrebbe significare un’interpretazione concordata dei valori di lista e una copertura di regressione per entrambe le forme.
