Struct RequestVerifierAsync

pub struct RequestVerifierAsync { /* private fields */ }

Exposes verify method and caches new certificates asynchronously on the first request

Implementations

impl RequestVerifierAsync

pub fn new() -> Self

Create default instance with an empty cache

pub async fn verify( &self, signature_cert_chain_url: &str, signature: &str, body: &[u8], timestamp: &str, timestamp_tolerance_millis: Option<u64>, ) -> Result<(), Error>

Asynchronously verify that the request came from Alexa. Returns a std::future::Future that can .await’d.

• SignatureCertChainUrl and Signature are headers of the request

• Pass the entire body of the request for signature verification

• Timestamp comes from the body, { "request" : { "timestamp": "" } }. If deserialized using alexa_sdk then timestamp can be taken from alexa_sdk::Request.body.timestamp

• A tolerance value in milliseconds can be passed to verify the request was received within that tolerance (default is 150_000)
