阅读更多关于 How to serve static files in FastAPI

问题 I am trying to serve static files that I have in a package_docs directory. When I open in the browzer: http://127.0.0.1:8001/packages/docs/index.html , the page is running. But I want to open the page: http://127.0.0.1:8001/packages/docs/ without the source file. And the output is 404 Not Found app.mount("/packages/docs", StaticFiles(directory=pkg_resources.resource_filename(__name__, 'package_docs') ), name="package_docs") @app.get("/packages/docs/.*", include_in_schema=False) def root():

Python pkg_resources and file access in packages

阅读更多关于 Python pkg_resources and file access in packages

问题 I'm building my first python package (which I then install with pip) and I need to use some non-python files. In these answers, it is explained that I should use the pkg_resources function. But I can't figure out a working example. Let say I have this project structure: package_name/ ----data/ --------image.png ----package_name/ --------__init__.py --------file.py ----setup.py ----MANIFEST.in ----conf.yml Now I want to access conf.yml and image.png from file.py . How should I proceed in: file

Accessing files in python egg from inside the egg

阅读更多关于 Accessing files in python egg from inside the egg

问题 The question is an attempt to get the exact instruction on how to do that. There were few attempts before, which don't seem to be full solutions: solution to move the file inside the package solution to read as zip accessing meta info via get_distribution The task at hand is to read the information about the egg the program is running from. There are few ways as i understand: hard code the location of the egg and treat it as zip archive - will work, but not flexible enough, because it will

Accessing python egg's own metadata

阅读更多关于 Accessing python egg's own metadata

问题 I've produced a python egg using setuptools and would like to access it's metadata at runtime. I currently got working this: import pkg_resources dist = pkg_resources.get_distribution("my_project") print(dist.version) but this would probably work incorrectly if I had multiple versions of the same egg installed. And if I have both installed egg and development version, then running this code from development version would pick up version of the installed egg. So, how do I get metadata for my
