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.

"Unwraps" a CompletionStage<T> and runs the inner route when the stage has failed with the stage's failure exception as an extraction of type Throwable. If the completion stage succeeds the request is completed using the values marshaller (This directive therefore requires a marshaller for the completion stage value type to be provided.)

Uses the marshaller for the given type to produce a completion function that is passed to its inner function. You can use it do decouple marshaller resolution from request completion.

Wraps its inner route with support for Conditional Requests as defined by http://tools.ietf.org/html/rfc7232

Changes the HTTP method of the request to the value of the specified query string parameter. If the query string parameter is not specified this directive has no effect. If the query string is specified as something that is not a HTTP method, then this directive completes the request with a 501 Not Implemented response.

This directive is useful for:

• Use in combination with JSONP (JSONP only supports GET)
• Supporting older browsers that lack support for certain HTTP methods. E.g. IE8 does not support PATCH

Always passes the request on to its inner route (i.e. does nothing with the request or the response).

Consumes a leading slash and extracts the next path segment, unmarshalling it and passing the result to the inner function, expecting the full path to have been consumed then.

Applies the given PathMatcher0 to the remaining unmatched path after consuming a leading slash. The matcher has to match the remaining path completely. If matched the value extracted by the PathMatcher0 is extracted on the directive level.

Matches a prefix to the remaining unmatched path after consuming a leading slash. The matcher has to match the remaining path completely. If matched the value matching the prefix is extracted on the directive level.

Rejects the request if the unmatchedPath of the akka.http.javadsl.server.RequestContext is non-empty, or said differently: only passes on the request to its inner route if the request path has been matched completely.

Only passes on the request to its inner route if the request path has been matched completely or only consists of exactly one remaining slash.

Note that trailing slash and non-trailing slash URLs are not the same, although they often serve the same content. It is recommended to serve only one URL version and make the other redirect to it using #redirectToTrailingSlashIfMissing or #redirectToNoTrailingSlashIfPresent directive.

For example:

def route = {
  // redirect '/users/' to '/users', '/users/:userId/' to '/users/:userId'
  redirectToNoTrailingSlashIfPresent(Found) {
    pathPrefix("users") {
      concat(
        pathEnd {
          // user list ...
        },
        path(UUID) { userId =>
          // user profile ...
        }
      )
    }
  }
}

Consumes a leading slash and extracts the next path segment, unmarshalling it and passing the result to the inner function.

Applies the given PathMatcher0 to the remaining unmatched path after consuming a leading slash. The matcher has to match a prefix of the remaining path. If matched the value extracted by the PathMatcher is extracted on the directive level.

Matches a prefix to the remaining unmatched path after consuming a leading slash. The matcher has to match a prefix of the remaining path. If matched the value matching the prefix is extracted on the directive level.

Checks whether the unmatchedPath of the akka.http.javadsl.server.RequestContext has a prefix matched by the given PathMatcher. In analogy to the pathPrefix directive a leading slash is implied.

Only passes on the request to its inner route if the request path consists of exactly one remaining slash.

Applies the given akka.http.scaladsl.server.PathMatcher to a suffix of the remaining unmatchedPath of the akka.http.javadsl.server.RequestContext. If matched the value extracted by the akka.http.javadsl.server.PathMatcher0 is extracted and the matched parts of the path are consumed. Note that, for efficiency reasons, the given akka.http.javadsl.server.PathMatcher0 must match the desired suffix in reversed-segment order, i.e. pathSuffix("baz" / "bar") would match /foo/bar/baz!

Checks whether the unmatchedPath of the akka.http.javadsl.server.RequestContext has a suffix matched by the given PathMatcher. However, as opposed to the pathSuffix directive the matched path is not actually "consumed". Note that, for efficiency reasons, the given PathMatcher must match the desired suffix in reversed-segment order, i.e. pathSuffixTest("baz" / "bar") would match /foo/bar/baz!

Injects the given value into a directive.

Applies the given matcher directly to a prefix of the unmatched path of the akka.http.javadsl.server.RequestContext (i.e. without implicitly consuming a leading slash). The matcher has to match a prefix of the remaining path. If matched the value extracted by the PathMatcher is extracted on the directive level.

Checks whether the unmatchedPath of the akka.http.javadsl.server.RequestContext has a prefix matched by the given PathMatcher. However, as opposed to the pathPrefix directive the matched path is not actually "consumed".

If the request path ends with a slash, redirect to the same uri without trailing slash in the path.

Caveat: #pathSingleSlash directive will not match inside of this directive.

If the request path doesn't end with a slash, redirect to the same uri with trailing slash in the path.

Caveat: #path without trailing slash and #pathEnd directives will not match inside of this directive.

Converts responses with an empty entity into (empty) rejections. This way you can, for example, have the marshalling of a None option be treated as if the request could not be matched.

Unmarshalls the request using the given unmarshaller, and passes the result to [inner]. If there is a problem with unmarshalling the request is rejected with the akka.http.javadsl.server.Rejection produced by the unmarshaller.

Rejects the request with an UnsupportedRequestEncodingRejection if its encoding doesn't match the given one.

Rejects if the request entity is non-empty.

Rejects with a RequestEntityExpectedRejection if the request entity is empty. Non-empty requests are passed on unchanged to the inner route.

Rejects the request with an UnacceptedResponseEncodingRejection if the given response encoding is not accepted by the client.

Inspects the request's Accept-Language header and determines, which of the given language alternatives is preferred by the client. (See http://tools.ietf.org/html/rfc7231#section-5.3.5 for more details on the negotiation logic.) If there are several best language alternatives that the client has equal preference for (even if this preference is zero!) the order of the arguments is used as a tie breaker (First one wins).

If [languages] is empty, the route is rejected.

Adds a Set-Cookie response header with the given cookies.

Adds a Set-Cookie response header with the given cookie.

Streams the bytes of the file submitted using multipart with the given file name into a designated file on disk. If there is an error writing to disk the request will be failed with the thrown exception, if there is no such field the request will be rejected, if there are multiple file parts with the same name, the first one will be used and the subsequent ones ignored.

Streams the bytes of the file submitted using multipart with the given field name into designated files on disk. If there is an error writing to disk the request will be failed with the thrown exception, if there is no such field the request will be rejected.

Inspects the response entity and adds a Content-Encoding: gzip response header if the entity's media-type is precompressed with gzip and no Content-Encoding header is present yet.

Answers GET requests with an Accept-Ranges: bytes header and converts HttpResponses coming back from its inner route into partial responses if the initial request contained a valid Range request header. The requested byte-ranges may be coalesced. This directive is transparent to non-GET requests Rejects requests with unsatisfiable ranges UnsatisfiableRangeRejection. Rejects requests with too many expected ranges.

Note: if you want to combine this directive with conditional(...) you need to put it on the *inside* of the conditional(...) directive, i.e. conditional(...) must be on a higher level in your route structure in order to function correctly.

For more information, see: https://tools.ietf.org/html/rfc7233

Runs its inner route with the given alternative RoutingSettings.

Fails the stream with akka.http.scaladsl.model.EntityStreamSizeException if its request entity size exceeds given limit. Limit given as parameter overrides limit configured with akka.http.parsing.max-content-length.

Beware that request entity size check is executed when entity is consumed.

Disables the size limit (configured by akka.http.parsing.max-content-length by default) checking on the incoming akka.http.javadsl.model.HttpRequest entity. Can be useful when handling arbitrarily large data uploads in specific parts of your routes.
