[−][src]Struct gotham::router::route::matcher::accept::AcceptHeaderRouteMatcher
A RouteMatcher
that succeeds when the Request
has been made with an Accept
header that
includes one or more supported media types. A missing Accept
header, or the value of */*
will also positvely match. It supports the quality weighted syntax, but does not take the quality
into consideration when matching.
Examples
let supported_media_types = vec![mime::APPLICATION_JSON, mime::IMAGE_STAR]; let matcher = AcceptHeaderRouteMatcher::new(supported_media_types); // No accept header state.put(HeaderMap::new()); assert!(matcher.is_match(&state).is_ok()); // Accept header of `*/*` let mut headers = HeaderMap::new(); headers.insert(ACCEPT, "*/*".parse().unwrap()); state.put(headers); assert!(matcher.is_match(&state).is_ok()); // Accept header of `application/json` let mut headers = HeaderMap::new(); headers.insert(ACCEPT, "application/json".parse().unwrap()); state.put(headers); assert!(matcher.is_match(&state).is_ok()); // Not a valid Accept header let mut headers = HeaderMap::new(); headers.insert(ACCEPT, "text/plain".parse().unwrap()); state.put(headers); assert!(matcher.is_match(&state).is_err()); // At least one supported accept header let mut headers = HeaderMap::new(); headers.insert(ACCEPT, "text/plain".parse().unwrap()); headers.insert(ACCEPT, "application/json".parse().unwrap()); state.put(headers); assert!(matcher.is_match(&state).is_ok()); // Accept header of `image/*` let mut headers = HeaderMap::new(); headers.insert(ACCEPT, "image/*".parse().unwrap()); state.put(headers); assert!(matcher.is_match(&state).is_ok());

impl RouteMatcher for AcceptHeaderRouteMatcher
[src]
fn is_match(&self, state: &State) -> Result<(), RouteNonMatch>
[src]
Determines if the Request
was made using an Accept
header that includes one or more
supported media types. A missing Accept
header, or the value of */*
will also positvely
match.
Quality values within Accept
header values are not considered by the matcher, as the
matcher is only able to indicate whether a successful match has been found.
