Hey 👋,

Thanks for your pull request to Inertia!

Could you please provide additional information that includes an explanation of the exact problem, how to reproduce said problem, and how this change fixes that problem? It is difficult for us to consider pull requests without this, as it otherwise may introduce breaking changes to the library.

Thanks!

Problem Introduce

Inertia generates the wrong url when the Laravel project deploys under the subfolder of the domain.

How To Reproduce

This problem only occurs when you deploy your Laravel project in a subfolder of the domain like this.

https://my.domain/to/project

NGINX setting (reverse proxy) maybe like this

server {
  listen 80;
  listen [::]:80;

  server_name _;
  location /to/project/ {
    proxy_set_header X-Forwarded-Prefix /to/project;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
    proxy_set_header X-Forwarded-Host my.domain;
    proxy_set_header X-Forwarded-Port 443;
    # laravel backend at localhost:8080
    proxy_pass http://localhost:8080/;
}

In the said condition below, inertia will set url = `` when user requests https://my.domain/to/project, cause user's browser URL to be rewritten as `https://my.domain/`.

Fix

toResponse($request) (in src/Response.php) doesn't consider base URL in $page.url. This PR just add base URL in front of request URI to fix it.

<?php
...
class Response implements Responsable
{
    use Macroable;
    ...

    public function toResponse($request)
    {
        ...
        $page = [
            'component' => $this->component,
            'props' => $props,
            'url' => $request->getBaseUrl().$request->getRequestUri(),
            'version' => $this->version,
        ];
        ...
        return ResponseFactory::view($this->rootView, $this->viewData + ['page' => $page]);
    }
}
