使用Firebase Dynamic Links 實現PHP 安全驗證機制

<?php
$link = "https://YOUR_SHORT_LINK_URL";
$apiKey = "YOUR_FIREBASE_API_KEY";
$data = [
    "longDynamicLink" => $link,
    "suffix" => [
        "option" => "SHORT"
    ]
];
$options = [
    "http" => [
        "header" => "Content-type: application/json",
        "method" => "POST",
        "content" => json_encode($data)
    ]
];
$context = stream_context_create($options);
$result = file_get_contents("https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=" . $apiKey, false, $context);
$response = json_decode($result, true);

if ($response && isset($response["shortLink"])) {
    echo "Short Link: " . $response["shortLink"];
} else {
    echo "Failed to generate short link";
}
?>
    

FirebaseDynamicLinks.instance()?.handleUniversalLink(userActivity.webpageURL!) { (dynamicLink, error) in
    if let dynamicLink = dynamicLink {
        // 從鏈接參數中獲取驗證信息let customParameters = dynamicLink.customParameters
        let verificationToken = customParameters?["verification_token"]
        
        // 將驗證信息發送到PHP 後端進行驗證let url = URL(string: "https://YOUR_PHP_SERVER/verify.php")!
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        request.httpBody = "verification_token=\(verificationToken)".data(using: .utf8)

        let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
            if let data = data {
                // 處理從PHP 後端返回的驗證結果let responseString = String(data: data, encoding: .utf8)
                print(responseString)
            }
        }
        task.resume()
    }
}
    

<?php
$verificationToken = $_POST['verification_token'];
// 在此處進行驗證邏輯，比如驗證該 token 是否有效

// 返回驗證結果給移動應用
echo "Verification Success";
