Catching the g-recaptcha-response in ASP.NET MVC is a simple way to add an extra layer of security to your application. This is especially important when handling sensitive data or user information.
There are a few steps that need to be taken to successfully catch and use this piece of information.
Add the ReCaptcha Control to the page -
The first step is to add the captcha control to the page. You can do this either by manually typing the code into the page or by using a third-party library such as ReCaptcha.Net.
Handle the request -
The second step is to have your controller handle the request. You will need to set up a method to receive and capture the g-recaptcha-response from the page. You can use the Request object to get the response from the form or from the QueryString. Use the following code snippet to get the response:
string gRecaptchaResponse = Request[“g-recaptcha-response”];
- Verify the Captcha Response -
Finally, you will need to use the Captcha Verification API to check if the response is valid. The API is fairly straightforward and will return either true or false depending on the validity of the response.
Hopefully, this guide has provided you with everything you need to get started with catch and using the g-recaptcha-response in your ASP.NET MVC application. For more detailed information, you can check out Google's official tutorial here: https://developers.google.com/recaptcha/docs/v3
