Importing images about flask-weasyprint HOT 2 CLOSED

Hi, thank you for taking the time to report this issue!

weasyprint.urls.URLFetchingError: ValueError: Flask-WeasyPrint got HTTP status 404 NOT FOUND for https://performance.pythonanywhere.comb'/static/graphs/pi_graph.png'

I've seen the b'…' problem before, but as long as I can remember it's "just" an error when building the error message (ie the real URL doesn't have the b'…' part).

Is there a way of creating a custom url_fetcher in order to rectify this issue?

Of course you can: you have to create a function and give it to HTML as done in WeasyPrint's documentation.

The problem is that Flask-WeasyPrint tries to avoid HTTP requests for you, and that you'll have to handle this too (if you have authentication for example). It would be a better idea to understand why the request fails, and even to fix the problem in Flask-WeasyPrint or in your application if possible.

Is there a reason why your application prevents the client from getting static files (like specific configuration)?

return render_pdf("https://performance.pythonanywhere.com/static/graphs/pi_graph.png")

Just to be sure (but you probably know that): your example will never work because you're trying to render a PNG file and not an HTML file.

Hey, Thank you for getting back to me.

I did think that the error may just be on the error generation not on the link it was attempting to access.

Is there a reason why your application prevents the client from getting static files (like specific configuration)?

Well i had tried serving a static file of the image and then referencing it with but it wouldn't work for the life of me. Turns out it just took adding in the "file://" with a direct path to the image and it popped up and works great (this took three and a half days of misery to reach).

Thanks for your help and assistance
