IpController

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Http;

class IpController extends Controller
{
    public function server()
    {
        $info = ['ip'=>'Unknown', 'country'=>'Unknown', 'region'=>'Unknown', 'city'=>'Unknown'];
        try {
            // Server-side call to /info: checks the server outbound IP.
            $response = Http::timeout(3)->get('https://my.ipin.io/info');
            if ($response->successful()) { $info = array_merge($info, $response->json()); }
        } catch (\Throwable $e) {}
        return view('server-ip', ['info' => $info]);
    }

    public function download()
    {
        return view('download');
    }
}

server-ip.blade.php

<div class="server-ip-box">
  <h2>Server outbound IP information</h2>
  <p>IP：{{ $info['ip'] }}</p>
  <p>Country：{{ $info['country'] }}</p>
  <p>Region：{{ $info['region'] }}</p>
  <p>City：{{ $info['city'] }}</p>
</div>

download.blade.php

<div class="download-box">
  <a id="ipinDownloadBtn" href="/download/default/app.zip">Download</a>
  <p id="ipinDownloadNode">Default</p>
</div>
<script>
(async function () {
  const el = document.getElementById("ipinDownloadNode");
  const btn = document.getElementById("ipinDownloadBtn");
  const defaultText = "Welcome. This is the default content.";
const contentMap = { TW: "Content for Taiwan visitors", US: "Content for United States visitors", JP: "Content for Japan visitors" };
try {
  // Browser-side call to /info: detects the visitor IP.
  const info = await fetch("https://my.ipin.io/info").then(res => res.json());
  el.textContent = contentMap[info.country] || defaultText;
} catch (e) {
  // Keep the default value when the API request fails.
  el.textContent = defaultText;
}
  const nodeMap = { TW: "/download/tw/app.zip", US: "/download/us/app.zip", JP: "/download/jp/app.zip" };
  try {
    const info = await fetch("https://my.ipin.io/info").then(res => res.json());

    el.textContent = info.country || "Default";
  } catch (e) { btn.href = "/download/default/app.zip"; }
})();

routes/web.php

use App\Http\Controllers\IpController;

Route::get('/server-ip', [IpController::class, 'server']);
Route::get('/download', [IpController::class, 'download']);
