How to display a pdf file on a new page?

Question

Flask

Good afternoon.

The essence of the question is this: when a user clicks on a button, you need to open a new browser tab and display a pdf file on it, without changing the page on which this button was clicked.

PS I tried to redirect the user to a new url through redirect, and there already open a new tab. Through this method, a POST request is sent, but for some reason the new url accepts GET and therefore I cannot output the pdf file only if the html template.

Answer 1

Or I didn't understand something. But this seems to be done at the html level with target="_blank"

<a href="http://example.com" target="_blank">go</a>

In Flask, you can also do this:

from flask import  send_file
return send_file(report_file_pdf, as_attachment=True)

Answer 2

An appropriate Content-Disposition HTTP header must be specified
