从网页跳转至React Native应用：PHP端跳转配置求助

Got it, let's walk through how to set up the PHP side of your deep link—your AndroidManifest.xml configuration looks solid already!

First, a quick recap of your Android setup: you’ve defined a deep link with scheme="exampleapp", host="greetings", and pathPrefix="/". That means any URL starting with exampleapp://greetings will trigger your React Native app to open.

Option 1: Simple PHP Header Redirect #

If you just need a straightforward redirect to the app, use PHP’s header() function. Just make sure this code runs before any HTML output (no echo statements or whitespace before the <?php tag):

<?php
// Redirect directly to your app's deep link
header("Location: exampleapp://greetings");
exit; // Always exit after a header redirect to stop further code execution
?>

⚠️ Heads up: If the user doesn’t have your app installed, their browser will show an error like "Cannot open link". For a smoother user experience, go with the smarter approach below.

Option 2: Smart Redirect (Fallback to App Store) #

This method tries to open the app first, and if that fails after a short delay, it redirects the user to your app’s Google Play Store page. Combine PHP and JavaScript for this:

<?php
// Optional: Dynamically add a path to pass data to your app (e.g., a user ID or screen route)
$optionalPath = isset($_GET['route']) ? '/' . $_GET['route'] : '';
$deepLink = "exampleapp://greetings{$optionalPath}";
// Replace with your app's actual Play Store URL
$playStoreLink = "https://play.google.com/store/apps/details?id=com.your.app.package";
?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Opening Your App...</title>
</head>
<body>
    <p>Please wait while we open the app...</p>
    <p>If nothing happens, <a href="<?= htmlspecialchars($playStoreLink) ?>">click here to download our app</a>.</p>

    <script>
        // Attempt to open the app immediately
        window.location.href = "<?= htmlspecialchars($deepLink) ?>";

        // If the app doesn't open after 5 seconds, redirect to the Play Store
        setTimeout(() => {
            window.location.href = "<?= htmlspecialchars($playStoreLink) ?>";
        }, 5000);
    </script>
</body>
</html>

Key Tips: #

• Pass Data via Deep Link: Since your pathPrefix="/" matches any subpath, you can extend the link (e.g., exampleapp://greetings/user/123) to send data to your React Native app. Your app can then parse this path to navigate to specific screens or load user-specific content.
• Security First: Use htmlspecialchars() when outputting dynamic URLs in HTML/JS to prevent cross-site scripting (XSS) attacks.
• iOS Support: If you need to support iOS later, you’ll need to add similar deep link configuration in your Info.plist file—but the PHP redirect logic will work the same way.
