I am at my wits' end attempting to integrate Google's recaptcha v2 with a simple HTML form. I hope someone can help.
In the <head> of the form page I have
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
as directed by Google.
Within the form I have
<div class="g-recaptcha" data-sitekey="xxxxxxxxxxx"></div>
where xxxxxxxxxxx is the sitekey provided by Google. When the form is displayed, this is properly creating the recaptcha widget.
On the target page that processes the form submission, I have this:
<cfset form.RecaptchaResponse = "">
<cfif StructKeyExists(form, "g-recaptcha-response")>
<cfset form.RecaptchaResponse = form["g-recaptcha-response"]>
</cfif>
<cfhttp url="https://www.google.com/recaptcha/api/siteverify" method="post" result="captchaResult">
<cfhttpparam type="formfield" name="secret" value="zzzzzzzz">
<cfhttpparam type="formfield" name="response" value="#form.RecaptchaResponse#">
<cfhttpparam type="formfield" name="remoteip" value="#cgi.remote_addr#">
</cfhttp>
<cfset result = "#deserializeJSON(StructFind(variables.captchaResult, 'FileContent'))#">
<cfif result.success is "false">
<cflocation addtoken="no" URL="/">
</cfif>
...start processing the submission.
where zzzzzzzz is the secret key provided by Google.
First I intentionally submit the form without responding to the captcha. I dump the variable captchaResult (a structure). Its 'FileContent' key is a JSON string, and in that string, 'Success' is 'false'. This submission redirects to the site's home page -- exactly as desired.
Next I submit the form correctly, including responding to the captcha. Dumping captchaResult and then aborting, I see that 'Success' is 'true'. In other words, Google is definitely passing this submission.
So now I reload everything and resubmit correctly, including responding to the captcha. ColdFusion replies with this on my target page:
We're sorry...
Element G is undefined in FORM.
The error occurred on line 1.
What the #$% is going on?? Any suggestions will be gratefully and humbly accepted.
