Method Detail

checkSameOrigin

public Route checkSameOrigin(HttpOriginRange allowed,
                             java.util.function.Supplier<Route> inner)

Checks that request comes from the same origin. Extracts the Origin header value and verifies that allowed range contains the obtained value. In the case of absent of the Origin header rejects with MissingHeaderRejection. If the origin value is not in the allowed range rejects with an InvalidOriginRejection and StatusCodes.FORBIDDEN status.

Parameters:

allowed - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

headerValue

public <T> RouteAdapter headerValue(java.util.function.Function<HttpHeader,java.util.Optional<T>> f,
                                    java.util.function.Function<T,Route> inner)

Extracts an HTTP header value using the given function. If the function result is undefined for all headers the request is rejected with an empty rejection set. If the given function throws an exception the request is rejected with a MalformedHeaderRejection.

Parameters:

f - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

headerValueByName

public RouteAdapter headerValueByName(java.lang.String headerName,
                                      java.util.function.Function<java.lang.String,Route> inner)

Extracts the value of the first HTTP request header with the given name. If no header with a matching name is found the request is rejected with a MissingHeaderRejection.

Parameters:

headerName - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

headerValueByType

public <T extends HttpHeader> RouteAdapter headerValueByType(java.lang.Class<T> t,
                                                             java.util.function.Function<T,Route> inner)

Extracts the first HTTP request header of the given type. If no header with a matching type is found the request is rejected with a MissingHeaderRejection.

Parameters:

t - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

headerValuePF

public <T> RouteAdapter headerValuePF(scala.PartialFunction<HttpHeader,T> pf,
                                      java.util.function.Function<T,Route> inner)

Extracts an HTTP header value using the given partial function. If the function is undefined for all headers the request is rejected with an empty rejection set.

Parameters:

pf - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

optionalHeaderValue

public <T> RouteAdapter optionalHeaderValue(java.util.function.Function<HttpHeader,java.util.Optional<T>> f,
                                            java.util.function.Function<java.util.Optional<T>,Route> inner)

Extracts an optional HTTP header value using the given function. If the given function throws an exception the request is rejected with a MalformedHeaderRejection.

Parameters:

f - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

optionalHeaderValueByName

public RouteAdapter optionalHeaderValueByName(java.lang.String headerName,
                                              java.util.function.Function<java.util.Optional<java.lang.String>,Route> inner)

Extracts the value of the optional HTTP request header with the given name.

Parameters:

headerName - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

optionalHeaderValueByType

public <T extends HttpHeader> RouteAdapter optionalHeaderValueByType(java.lang.Class<T> t,
                                                                     java.util.function.Function<java.util.Optional<T>,Route> inner)

Extract the header value of the optional HTTP request header with the given type.

Parameters:

t - (undocumented)

inner - (undocumented)

Returns:

(undocumented)

optionalHeaderValuePF

public <T> RouteAdapter optionalHeaderValuePF(scala.PartialFunction<HttpHeader,T> pf,
                                              java.util.function.Function<java.util.Optional<T>,Route> inner)

Extracts an optional HTTP header value using the given partial function. If the given function throws an exception the request is rejected with a MalformedHeaderRejection.
