Recaptcha-rs is a very simple library to verify recaptcha responses.
To use recaptcha-rs in your project you can add the following to your Cargo.toml:
[dependencies]
recaptcha = "0.5.0"Verifying recaptcha responses is very easy:
extern crate recaptcha;
fn main() {
let remote_ip = "123.123.123.123".parse().ok();
let res = recaptcha::verify("your_private_key", "user_response", remote_ip).await;
if res.is_ok() {
println!("Success");
} else {
println!("Failure");
}
}
