Cloudflare Laravel Request

Cloudflare Laravel Request inherits the request object from Laravel and parses specific headers from Cloudflare to provide additional information about the request, including:

• CfRequest::ip() - Original Client IP (Before it passes through any proxies)
• CfRequest::country() - Origin Country
• CfRequest::timezone() - Origin Timezone
• CfRequest::city() - Origin City
• CfRequest::region() - Origin Region
• CfRequest::postalCode() - Origin Postal Code
• CfRequest::lat() - Origin Latitude
• CfRequest::lon() - Origin Longitude
• CfRequest::isBot() - If it's a bot
• CfRequest::threatScore() - Threat Score from Cloudflare

The User-Agent is also parsed to provide additional information about the device, including:

• CfRequest::deviceType() - Device Type (mobile, tablet, desktop, tv, etc)
• CfRequest::deviceBrand() - Device Brand
• CfRequest::deviceModel() - Device Model
• CfRequest::os() - Device OS
• CfRequest::osVersion() - Device OS Version
• CfRequest::browser() - Device Browser
• CfRequest::browserVersion() - Device Browser Version

With this package, you can:

• Replace Request $request with CfRequest $request in your controller methods to access the additional methods.
• Call the CfRequest facade anywhere in your application to access this information.

Highlights

Lean into Cloudflare's Security

public function register(CfRequest $request)
{
    if ($request->isBot()) {
        abort(403, 'Naughty bots');
    }
    if ($request->threatScore() > 50) {
        abort(403, 'Thanks but no thanks');
    }
    $attributes = $request->validate([
        'first_name' => 'required|string',
        'last_name' => 'required|string',
        //... etc
    ]);
   //... etc
}

Set the timezone based on the origin

date_default_timezone_set(CfRequest::timezone());
// Now carbon dates will be parsed for the user's timezone

Apply logic based on the user's country

public function welcome()
{
   if (CfRequest::country() === 'US') {
         return view('welcome_us');
   }
   return view('welcome');
}

Apply logic based on device type

public function welcome()
{
    $loadVideo = true;
    if (CfRequest::deviceType() === 'mobile') {
        $loadVideo = false;
    }
    // etc
}
