Umami

PHP Proxy

To serve the umami tracking script and api over the same host I use the following simple php script.

umami-proxy.php

<?php

// Define the target URL
$targetUrl = "<umami-host>";

// Get the client request URL
$clientUrl = $_SERVER['REQUEST_URI'];

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $targetUrl . $clientUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$request_headers = [
  'Content-Type:application/json',
  'Accept:application/json'
];

if ($_SERVER['REQUEST_METHOD'] === "POST") {
    $body = file_get_contents('php://input');
    $data = json_decode($body, True);

    if ($_SERVER['REQUEST_URI'] === "/api/send") {
        $data["payload"]["ip"] = $_SERVER['REMOTE_ADDR'];
    }

    array_push($request_headers, "User-Agent:{$_SERVER['HTTP_USER_AGENT']}");
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
}

// Execute the cURL request
$response = curl_exec($ch);

// Get the response headers
$responseHeaders = curl_getinfo($ch);

// Close the cURL session
curl_close($ch);

// Forward the response headers to the client
foreach ($responseHeaders as $headerName => $headerValue) {
    header("$headerName: $headerValue");
}

// Forward the response body to the client
echo $response;
?>

To serve only the required endpoint over the proxy add the following config to your .htaccess.

.htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^script.js$ umami-proxy.php
RewriteRule ^api/send$ umami-proxy.php
</IfModule>
