A WSGI web service for rendering HTML to PDF using wkhtmltopdf.
This work was inspired by https://github.com/openlabs/docker-wkhtmltopdf
- Add the javascript client
- Add a routing system
- Use URL params to generate wkhtmltopdf cmd-line options
- Add a cache system
- Add a
Procfile
and.buildpack
for a better Heroku compatibility - Add an auth system
-
Install python3 (virtualenv recommendend)
-
Install
wkhtmltopdf
here -
Install dependencies:
pip3 install -r requirements.txt
-
Run server:
python3 app.py
The development server listens on port 5000.
The web service accepts an HTML document as the "html" and "filename" parameter in the body of a URL-encoded web form POST request and responds with the rendered PDF. For example:
curl -d html='<p>Hello world!</p>' -d filename='test.pdf' http://localhost:5000 > output.pdf
An HTML file can also be included as multipart form data, for example:
cat sample.html | curl -F html=@- http://localhost:5000 > output.pdf
To run the service as a Docker container:
-
Build the Docker image:
docker build -t printer-webservice .
-
Run a Docker container (binding to port 5000):
docker run -p 5000:8080 printer-webservice
