Struct alexa_verifier::RequestVerifier

pub struct RequestVerifier { /* fields omitted */ }

Exposes verify method and caches new certificates on the first request

Methods

impl RequestVerifier

pub fn new() -> Self

Create default instance with an empty cache

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

Verify that the request came from Alexa.

• 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)
