Using reCAPTCHA on localhost

Question

I'm developing a website using PHP and I want to make a human verification in one of the sessions. For the development, I'm initially running the system locally and when it is ready, I'm gonna make put it on in a certain domain.

In the reCAPTCHA website it is said that the plugin will only work at the given domain (and subdomains).

My question is: Is there any way to use the reCAPTCHA plugin on a localhost?

Answer 1

I was recently working on creating a website involving recaptcha v2 and I have a need to do test automation on my localhost. I did not add any ip or localhost into recaptcha admin portal.

Follow the below steps

1. Log in to recaptcha admin site screenshot

2. Locate Key Settings

3. Click on advanced settings

4. Under Domain Name Validation, un-check Verify the origin of reCAPTCHA solutions checkbox. This option is used to verifying requests come from one of the above listed domains.

   Please note that, If disabled, you are required to check the host-name on your server when verifying a solution.

I created a new key and disable this and use this key for testing in localhost.

This is a sample page which implements reCAPTCHA for comments.

Answer 2

It's so easy:

1. Go to your google reCaptcha admin panel
2. Add localhost & 127.0.0.1 to domains of a new site like the following image.

Update:

If your question is how to set reCaptcha in Google site for using it in localhost, then i has been wrote it above but if you are curious that how you can using reCAPTCHA on both localhost and website host by minimal codes in your controller and prevent some codes like ConfigurationManager.AppSettings["ReCaptcha:SiteKey"] in it then I help you with this extra description and codes in my answer.

Do you like the following GET and POST actions?

Google has recently changed stopped allowing localhost being allowed by default. (as touched upon by @Artur Cesar De Melo)This is under their FAQ's:

I'm getting an error "Localhost is not in the list of supported domains". This was working before, what should I do?

localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key.

1: Create a separate key for your development environment

2: Add 127.0.0.1 to the list of allowed domains

3: Save changes and allow up to 30 mins for changes to take affect

Answer 4

As per Google recaptcha documentation

localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key

Answer 5

Please note that as of 2016, ReCaptcha doesn't naively support localhost anymore. From the FAQ:

localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key.

So just add localhost to your list of domains for your site and you'll be good.
