Flask Redirect New Tab

Question

Does anyone know if flask redirect is able to open a link / URL in a new tab?

@app.route('/test')
def my_page():

  return redirect('http://mylink.com', 301)

I would like if the mylink website opened in a new tab, any insights?

I would think it would be easiest to have the link in the HTML open a new tab that points to `/test` and then let it redirect, like `New Tab Link`. If someone navigates directly to `/test` is there a reason you would want them to open a new tab? — Seberius, Oct 01 '13 at 23:33
When the user visits /test and performs a POST request the python function actually creates the link and I would like the user to be sent to the link that is created and have it open in a new tab. I hope that makes sense. — jmbmxer, Oct 02 '13 at 20:54

As far as I know that would not be a flask issue. You have to open a new tab within your html code or with Javascript.

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

The server has no power over what the browser does in this case.

You could also use Python's webbrowser module to open a page, if you'd like to avoid getting into the HTML

import webbrowser

@app.route('/test')
def my_page():
    return webbrowser.open_new_tab('http://mylink.com')

Does anyone care to comment on why opening a new tab from within Flask is a bad idea? – garettmd Apr 22 '16 at 16:53

This way doesent work if you upload your project in a Apache WSGI server. – Leo Jun 22 '16 at 09:28
Didn't quite work, getting "The view function did not return a valid response." error. – John Jiang Jul 21 '19 at 07:13

@JohnJiang Newer versions of Flask require you to `return` something in the response. I've updated the answer to reflect that. – garettmd Jul 24 '19 at 19:22

The problem with this approach is that the new tab opens on the server machine, not on the client (the computer where I am actually accessing the site). Is there any fix for that? – Krishnan Shankar Jul 22 '20 at 16:52
@KrishnanShankar the fix would be to use Marco's answer :) – garettmd Aug 05 '20 at 21:25
webbrowser will open a new tab on server side, he want it on client side – Jawad Jan 30 '22 at 18:29

If you're dealing with a form you can set target="_blank"

A slight adjustment to @garettmd that fixes @John Jiang's issue:

import webbrowser
from flask import Flask, redirect, url_for

@app.route("/test/")
def test():
    webbrowser.open("https://google.com")
    return redirect(url_for("index"))

This way we get to return a redirect (which we should probably do anyway) and we also get our new tab without "The view function did not return a valid response" error.

This did not work for me. I got a new tab with google but my redirect still loaded in the previous page. – magM Oct 25 '21 at 09:21
