How to serve static files in a directory

[bernhardreiter]

It would be nice if there was an example how to serve static files from a directory from within hug, so that other hug mechanisms, like authentication work. This can be needed to load a single page web application. (For example I am using hug as a prototyp serving backend in https://github.com/Intevation/intelmq-fody where it would be useful to serve the static files.)

In #43 (comment) the need for this can be seen. (There not solved by hug, but by pecan using static..)

There is an example of serving an image file using hug (path to served image is wrong and fixed in #426). For a static HTML page one would only need to set proper output format: output=hug.output_format.html.

Does this solve the issue? If not, then what would you change/improve?

[bernhardreiter]

@spock thanks for your consideration!

The example is about one single file, I would like to serve all files from a directory without
the need of specifying each file separately.

It already works as the example in my pull-request #429 shows.
I'd say it misses a bit of documentation.

a) the function decorated with hug.static() seems to be called before hug.startup() functions.
Is it only called once?

b) how are the filetypes determined?

[spock]

regarding b), I'd guess its output_format.file

Not having any luck with this using a PNG file. Is there another recommended way to do this?

@hug.get('/static/{static_file}', output=hug.output_format.file)
def static(static_file):
    if '..' in static_file:
        raise
    return open('static/{}'.format(static_file))

Thank you!

@teran-mckinney if you are trying to serve all files from a directory, then consider trying my example code at #429 . Should be something like (untested):

@hug.static('/static')
def my_static_dirs():
    return('/home/www/path-to-static-dir',)

@bernhardreiter thank you, that worked!

Another solution here.
How about using werkzeug.wsgi.DispatcherMiddleware ?
