Thank you for your help.
I'd like to include the file on S3 with the include feature of python3 HTML template jinja2, but I don't know what to do.
<divid="sample">
<!--Read sample HTML-->
{% include "https://.../sample.html"%}
</div>
As mentioned above, specifying the full path of the HTML file on S3 also failed.
Ideally, I would like to download HTML on S3 into memory and embed the data in the div tag with jinja2. What should I do?
python html python3
You cannot include a file on your network using the include feature of jinja2, but you can do it by writing a function to retrieve it and passing it to jinja2 at render.
Below is a sample code.
from jinja2 import Environment, select_autoescape, FileSystemLoader
import urllib.request
def include_from_url(url):
with urllib.request.urlopen(url)asf:
return f.read()
env=Environment(
loader=FileSystemLoader('.',
autoescape=select_autoescape(['html','xml'],
)
template=env.get_template('template.html')
print(template.render(include_from_url=include_from_url))
template.html
<divid="sample">
<!--Read sample HTML-->
{{include_from_url('https://.../sample.html')}}
</div>
If you are using flask, you can use Context Processors.

return f.read()
