}
val onFailure: AuthedRoutes[String, IO] = Kleisli(req => OptionT.liftF(Forbidden(req.authInfo)))
val middleware = AuthMiddleware(authUser, onFailure)
object Auth extends AuthedContext[IO, User]
object BobRoutes extends RhoRoutes[IO] {
GET +? param("foo", "bar") >>> Auth.auth |>> { (foo: String, user: User) =>
Ok(s"Bob with id ${user.id}, foo $foo")
}
}
val service = middleware.apply(Auth.toService(BobRoutes.toRoutes()))This code is copied from AuthedContext.scala. But the Forbidden part is still "not found" after import bulk of things to make other part of code works... By the way, how to make service available for BlazeServerBuilder, or convert to HttpApp...?
Many thx!

F[_] instead of IO. Is RhoRoutes suitable for that? I guess it is, although all the example code / documentation uses IO. The reason I'm asking for is I have a route that returns different status codes based on some intermediate results and it works fine with IO but I can't get it to be of the required F[Result[...]] type with F[_]:ConcurrentEffect, instead it just defaults to Any As far as Intellij's shw implicits feature goes I can't see any difference. My ConcurrentEffect is being picked up instead of ioEffect which seems to be fine.
Hello there. Is it possible to get this feature backported to the 0.19.x releases series? We are stuck using the 0.20.x Http4s series right now, and we're trying to build some functionality that depends on the content-type headers:
Happy to open a PR against a branch if one is opened for me.
@zarthross is this something you can help me out with? We're using Rho internally but this is kind of a roadblock for us. We want to have a route support multiple content-types (e.g. json and proto), and we want to use the content-type header to control that. The Swagger document will unfortunately not work properly for this use case without that backport.
We are using 0.19.x because our team is still supporting Scala 2.11 at this time (and that cannot be changed until other vendor changes are completed).
Hello, I updated ther dependencies in my project,
cats-core = 2.1.1
cats-effect = 2.1.2
rho-swagger = 0.20.0
http4s-blaze-server = 0.21.0
now, I have a problem in start the project, the error is

pathVars not supported like query params in terms of Enums? See above. Both use a StringParser based on an Enumeratum enum, but the path param comes through odd
implicit def producerTypeStringParser[F[_]]: StringParser[F, ProducerType] =
new StringParser[F, ProducerType] {
override def parse(
s: String
)(implicit F: Monad[F]
): ResultResponse[F, ProducerType] =
try SuccessResponse(ProducerType.withName(s))
catch {
case _: NoSuchElementException =>
FailureResponse.pure[F] {
BadRequest.pure(s"Invalid ProducerType format: '$s'")
}
}
override val typeTag: Option[TypeTag[ProducerType]] = Some(
implicitly[TypeTag[ProducerType]]

val myIdsList = paramD[List[Long]]("myIds", "Some ids") which works as expected: it parses ?myIds=1&myIds=2 to a List[Long]. However, how can I use my own StringParser[IO, List[Long]] instead of QueryParsers.multipleParse? I'd like to manually parse ?myIds=1,2 to List[Long].
The above came up during an upgrade from v0.19.0 to v0.20.0 where I noticed that suddenly, our custom StringParser[IO, List[Long]] wasn't picked up and instead, QueryParsers.multipleParse was being used.
What I see is that v0.19.0's multiParse() is defined for Seq[_] while v0.20.0's multiParse() is defined for generic B[_].
I also see that QueryParsers.standardCollector and QueryParsers.multiParse are defined in the same scope. Would it help here if standardCollector had higher priority than multiParse()?
multiParse by defining the following: implicit def http4sMultipleParseOverride[A](
implicit F: Monad[IO],
p: StringParser[IO, List[A]],
cbf: Factory[A, List[A]]
): QueryParser[IO, List[A]] =
standardCollector[List[A]](F, p)
As an alternative to
'foo we've introduced pv"foo". pv stands for pathVar.You can see an example here https://github.com/http4s/rho/blob/master/examples/src/main/scala/com/http4s/rho/swagger/demo/MyRoutes.scala#L45
