如何对 akka-http 进行通用响应

Question

I need to create a function that evaluates to a Route given a Future[Either[Error, T]] I do it like this

def handleFuture[T] handleFuture(f: Future[Either[Error, T]]): Route = {
  onComplete(f) {
    case Failure(er) => complete(InternalServerError, err)
    case Success(Left(er)) => complete(BadRequest, er)
    case Success(Right(value)) => complete(OK, value)
  }
}

I have implicit marshallers/unmarshaller in scope for generic type A and I get a too many arguments for method complete error.

What am I doing wrong?

You have a typo. Change err to er :

case Failure(er) => complete(InternalServerError, er)
                                               // ^
