Making a route both intermediate and final? - swift

Question

In building an app with PerfectHTTP I've come up against a problem with routing: Routes that are used as intermediate routes cannot also be used as final routes.
When set up as below, some URLs track correctly (/index.html in the example), while some URLs do not (/ in the example).
Is there some special sauce I'm missing here, or is what I'm trying to do simply impossible using Perfect?
import PerfectHTTP
import PerfectHTTPServer
// This does various housekeeping to set things common to all requests.
var routes = Routes() {
request, response in
Log.info(message: "\(request.method) \(request.uri)")
response
.setHeader(.contentType, value: "text/plain")
.next()
}
// For this handler, http://localhost:8181/index.html works,
// but http://localhost:8181/ does not
routes.add(method: .get, uris: ["/", "index.html"]) {
request, response in
response
.appendBody(string: "Hello, world!")
.completed()
}
HTTPServer.launch(.server(name: "localhost", port: 8181, routes: [routes]))

Answer 1

if you want set things common to all requests. use filter.
my routes is working
see more https://perfect.org/docs/filters.html
var routes = Routes()
routes.add(method: .get, uris: ["/", "index.html"]) {
request, response in
response
.appendBody(string: "Hello, world!")
.completed()
}
struct MyFilter: HTTPRequestFilter {
func filter(request: HTTPRequest, response: HTTPResponse, callback: (HTTPRequestFilterResult) -> ()) {
print("request method: \(request.method)")
callback(.continue(request, response))
}
}
do {
let server = HTTPServer()
server.serverName = "testServer"
server.serverPort = 8181
server.addRoutes(routes)
server.setRequestFilters([(MyFilter(), HTTPFilterPriority.high)])
try server.start()
} catch {
fatalError("\(error)") // fatal error launching one of the servers
}
