Exceptions¶
In general, an exception breaks the normal flow of execution and executes a pre-registered exception handler.
The details of how this is done depends on how the exception is implemented. 1
There is some exceptions based on RFC7231 and supported in nanohttp:
Code |
Exception Name |
|---|---|
201 |
HTTPCreated |
202 |
HTTPAccepted |
203 |
HTTPNonAuthoritativeInformation |
204 |
HTTPNoContent |
205 |
HTTPResetContent |
206 |
HTTPPartialContent |
301 |

302 |

304 |
HTTPNotModified |
400 |

405 |
HTTPMethodNotAllowed |
409 |
HTTPConflict |
410 |
HTTPGone |
412 |
HTTPPreconditionFailed |
500 |
HTTPInternalServerError |
for using exceptions just raise it! like this:
from nanohttp import Controller, html, HttpNotFound
class Root(Controller):
@html
def index(self, user_id: str):
all_users = [12, 13, 14]
if not user_id in all_users:
raise HttpNotFound('User not found')
return '<p>Yes is here</p>'
Also you can define your own HTTP exception by using
nanohttp.exceptions.HttpStatus.
