How to pass username from auth_basic nginx to backend?

Question

Nginx

Nginx uses the auth_basic module to authorize users.

location  ~^/area {
            auth_basic            "closed site";
            auth_basic_user_file  htpasswd;
            try_files $uri @backend;
    }

How to get the username that was used during authorization on the backend?
I need to do this for the flask framework, but I think the principle should be the same everywhere.

Answer 1

There is a $remote_user variable . Pass just like any other variable.

Answer 2

If the backend is in PHP, then most likely so, let me know if it doesn’t work and indicate what your backend is on

<?php

echo '<pre>';
print_r($_SERVER);
echo '</pre>';
?>

Answer 3

If you need to check basic on the backend, then make this authorization the backend.
