It's impossible to get 'location' header on 302 redirect of wp_remote_post

[saturnix2025]

​https://wordpress.stackexchange.com/questions/398738/get-returned-url-from-wp-remote-post-if-response-code-is-302

<?php
$payload = array('body' => $payload);
$payload['redirection'] = 0;
$response = wp_remote_post( $my_url, $payload );
$redirect_to = wp_remote_retrieve_header( $reponse, 'location' );

In the above code, $redirect_to always returns an empty string when $my_url is an URL that returns 302 redirect.

This is unexpected behavior, as $redirect_to should contain the URL $my_url is redirecting us to.

I've tried replacing "location" with "Location" and "0" with "false" to no avail.

Hi @saturnix2025, thanks for opening this ticket and welcome to Trac!

Trac is for reporting issues with WordPress Core - so let's see if that's where this issue lies.

• What version of WordPress are you using?
• What is the output of var_dump( $response );?

Unfortunately I don't know, as this is shared hosting with no access to a dev console.

Version is 5.8.2

Hi all,

I've tried to replicate the issue, but it works as expected for me on WP 6.8.3.

Here is my environment info:

=== Environment
- WordPress: 6.8.3
- PHP: 8.4.10
- Server: nginx/1.26.1
- Database: mysqli (Server: 8.0.35 / Client: mysqlnd 8.4.10)
- Browser: Chrome 140.0.0.0
- OS: macOS
- Theme: Twenty Twelve 4.6
- MU Plugins:
  * z.php 
- Plugins:
  * Test Reports 1.2.0

=== Actual Results
1.  ❌ Error condition does not occur.

=== Additional Notes

Nginx config:
location = /trac54556 {
    return 302 /new-trac54556;
}

location = /new-trac54556 {
    return 200 "Hi";
}


Code used to confirm redirect URL is returned:

$response = wp_remote_get( "http://vanilla.local/trac54556", [ 'redirection' => 0 ] );
$redirect_to = wp_remote_retrieve_header( $response, 'location' );
echo '<pre>$redirect_to<br>' . print_r( $redirect_to, true ) . '</pre>';

Returns: http://vanilla.local:10008/new-trac54556

Since this ticket has been opened for ~4 years with no other reports, I'm going to close this to help clean up Trac. If this is still an issue for you, please feel free to reopen and provide any environmental information necessary to reproduce.
