Handler for validating URLs.

This is used for implementing domain blocklists and similar functionality. It is called with the ID of newly received activities, when fetching remote data from a given URL and before sending an activity to a given inbox URL. If processing for this domain/URL should be aborted, return an error. In case of Ok(()), processing continues.

#[derive(Clone)]
struct Verifier {
    db_connection: DatabaseConnection,
}

#[async_trait]
impl UrlVerifier for Verifier {
    async fn verify(&self, url: &Url) -> Result<(), Error> {
        let blocklist = get_blocklist(&self.db_connection).await;
        let domain = url.domain().unwrap().to_string();
        if blocklist.contains(&domain) {
            Err(Error::Other("Domain is blocked".into()))
        } else {
            Ok(())
        }
    }
}

Required Methods

fn verify<'life0, 'life1, 'async_trait>( &'life0 self, url: &'life1 Url ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Should return Ok iff the given url is valid for processing.
