var app = new Vue({
    el: '#app',
    data: {
        recaptchaKey: 'your-recaptcha-key',
        recaptchaResponse: ''
    },
    methods: {
        onRecaptchaVerified: function(response) {
            this.recaptchaResponse = response;
        },
        verifyRecaptcha: function() {
            axios.post('/verifyRecaptcha', {
                recaptchaResponse: this.recaptchaResponse
            })
            .then(function(response) {
                // Handle response
            })
            .catch(function(error) {
                // Handle error
            });
        }
    },
    mounted: function() {
        var self = this;
        grecaptcha.render('recaptcha', {
            sitekey: this.recaptchaKey,
            callback: function(response) {
                self.onRecaptchaVerified(response);
            }
        });
    }
});


  1. Create a route in your Laravel application to handle the reCaptcha verification:
1
Route::post('/verifyRecaptcha', 'RecaptchaController@verifyRecaptcha');


  1. Create a controller method to verify the reCaptcha token:

use IlluminateHttpRequest;

class RecaptchaController extends Controller
{
    public function verifyRecaptcha(Request $request)
    {
        $response = $request->input('recaptchaResponse');
        $secret = 'your-recaptcha-secret-key';

        $verify = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret={$secret}&response={$response}");

        $captcha_success = json_decode($verify);

        if ($captcha_success->success == false) {
            return response()->json(['error' => 'reCaptcha verification failed'], 400);
        }

        return response()->json(['success' => 'reCaptcha verification passed'], 200);
    }
}


  1. Make sure to include your reCaptcha keys (site key and secret key) in your environment configuration file (.env) for security reasons.


By following these steps, you can validate reCaptcha with Laravel and Vue.js in your application.
