http handlers

Available decorators are: action, html, text, json, xml, binary.

Those decorators are useful to encapsulate response preparation such as setting Content-Type HTTP header.

Take a look at the code of the action decorator, all other decorators are derived from this:

def action(*args, verbs: Union[str, list, tuple]='any', encoding: str='utf-8',
           content_type: Union[str, None]=None,
           inner_decorator: Union[callable, None]=None,
           prevent_empty_form=None, prevent_form=None, **kwargs):
    ...

Other decorators are defined using functools.partial:

html = functools.partial(action, content_type='text/html')
text = functools.partial(action, content_type='text/plain')
json = functools.partial(action, content_type='application/json', inner_decorator=jsonify)
xml = functools.partial(action, content_type='application/xml')
binary = functools.partial(action, content_type='application/octet-stream', encoding=None)

Of-course, you can set the response content type using:

context.response_content_type = 'application/pdf'

Of-course, you can define your very own decorator to make your code DRY:

import functools
from nanohttp import action, RestController

pdf = functools.partial(action, content_type='application/pdf')

class MyController(RestController)

    @pdf
    def get(index):
        .......
