问题
I tried using Piston for a simple API, hoping to use its OAuth support. But the first time I hit the endpoint after enabling OAuth, I got an error:
TemplateDoesNotExist: oauth/challenge.html
and sure enough, there is no such file.
Does OAuth work in Piston? Am I making a stupid mistake?
回答1:
Nope - that looks like a bug in Piston. oauth/challenge.html is referenced here, but does not exist anywhere in that project (see Piston's templates folder).
Could you try creating an empty oauth/challenge.html file somewhere in one of your directories specified in TEMPLATE_DIRS setting?
回答2:
The challenge method in the authentication object is called when checking is_authenticated fails. I haven't tested this, but I am led to believe that challenge.html is most likely rendered when authorization has failed and an error needs to be displayed.
This is only a guess, but I think that it makes sense.
