Hello everyone.

I followed the instructions in this link: reCAPTCHA V.2
I was able to get the keys and display the recaptcha object



But when the HTTJOB is executed the response is an error:
error-codes: [invalid-input-response]
success: false

I suspect that my error is in this line:
sb.Append("&response=").Append(ws.UpgradeRequest.GetParameter("g-recaptcha-response"))

B4X: 
Dim sb As StringBuilder
sb.Initialize
sb.Append("secret=").Append(Main.settings.Get("RecaptchaPrivateKey"))
sb.Append("&response=").Append(ws.UpgradeRequest.GetParameter("g-recaptcha-response")) '<------
j.PostString("https://www.google.com/recaptcha/api/siteverify", sb.ToString)

How should I get the parameter: g-recaptcha-response using websocket?

Thanks for your possible answers.

The s in https stands for secure, the WebSocket (WS) protocol missed the S from WSS(WebSocket Secure). The result of the un-encrypted WebSocket protocol is that the protocol information can be read by everyone or simple said: every one can steal the information. That's the reason why WebSocket is not used without additional measures.

Hi MicroDrie.
What you mean is that websocket does not require the use of recaptcha, and that a form with websocket cannot be attacked by a robot with false data and even bring down the server.
I don't need recaptcha with websocket?

What I mean is that you want find an implementation of re-captcha on the web socket protocol, re-captcha needs a successful secure connection.

Hi
I programmed the use of recaptcha/WebSocket on the production server that uses SSL and it still gives me:
error-codes: [invalid-input-response]
success: false

Could you provide me with an example of Recaptcha with WebSocket
