It seems like you're facing an issue with testing reCAPTCHA v3 on localhost. While reCAPTCHA v3 does have some constraints regarding its usage on localhost, there are typically workarounds or solutions you can apply to test it during development. Here are some steps you can take:
1. **Use a Local Domain Name:**
- Modify your hosts file to use a local domain name instead of `localhost`.
- For example, add `127.0.0.1 mylocaldomain.com` to your hosts file.
- Update your local server configuration to respond to `mylocaldomain.com`.
- Register `mylocaldomain.com` in the reCAPTCHA admin console as an allowed domain.
2. **Ngrok or Localtunnel:**
- Use a tunneling service like [Ngrok](
https://ngrok.com/) or [Localtunnel](
https://localtunnel.github.io/www/) to expose your local development server to the internet.
- Register the provided public URL in the reCAPTCHA admin console.
- This allows you to test reCAPTCHA as if it were on a live site.
3. **Temporary Deployment:**
- Deploy your application to a staging environment or a temporary live server.
- Ensure the staging domain is registered in the reCAPTCHA admin console.
- Perform your tests on this environment.
4. **HTTPS on Localhost:**
- Set up a self-signed certificate to serve your local development server over HTTPS.
- Modify your reCAPTCHA settings to allow HTTPS connections.
- Note that this may not fully resolve the domain issue, but it's good practice for other HTTPS-only services.
5. **Environment Configuration:**
- Make sure your environment configurations (API keys, secret keys, etc.) are correctly set for your local development.
- Double-check if reCAPTCHA is properly initialized in your development environment.
Here's a brief example of modifying the hosts file on a Unix-like system (Linux or macOS):
Add the following line:
Then, update your web server configuration to respond to `mylocaldomain.com` instead of `localhost`.
By using one of the methods above, you should be able to test reCAPTCHA v3 during your local development.
