The rust library captval is used with your backend service to verify the captval response provided from the client.
To use captval, add the following to your Cargo.toml:
[dependencies]
captval = "0.1.2"
Derive a validation method on the data structure representing your data, marking the captcha components in the data structure.
# use captcha::Captcha;
#[derive(Debug, Deserialize, Captcha)]
pub struct ContactForm {
name: String,
phone: String,
email: String,
message: String,
#[captcha]
token: String,
}Validate the captcha data.
# #[tokio::main]
# async main() -> Result<(), Box<dyn std::error::Error>> {
let contact_form: ContactForm = serde_json::from_str(e.body_string())?;
contact_form.valid_response(&secret, None).await?;
# }
# fn get_your_secret() -> String {
# "0x123456789abcde0f123456789abcdef012345678".to_string()
# }See the examples folder for an AWS Lambda contact form example.
Hcaptcha has been tested in a web assembly project using wasm-bindgen and node.
See the captval-wasm example for a sample project which can be run using wasm-pack test --node.
