I am trying a simple example where I am using a modification of the Dispatch example from the Scalatra site to make an async http request. The code is below. I get a compilation error that says value OK is not a member of String. I put together a standalone scala test with no Scalatra dependencies and it works as expected. I suspect OK is being pulled in from some Scalatra dependency. I am new to Scala and I am putting together a test web app using Scalatra. Any help will be appreciated. 

import dispatch._

trait AppAPIStack extends AppStack {
before() {
  contentType = "application/json"
}

object MyAsyncClient {

   def sendReq(phrase: param): Future[String] = {
     val searchURL = url("https://www.google.com/#q="+phrase)
     val result = dispatch.Http(searchURL OK as.String)
     for(r <- result) yield r
   }

   }
}

I fixed the issue by changing the line 

url("https://www.google.com/#q="+phrase)

to 

dispatch.url("https://www.google.com/#q="+phrase)

Dispatch and Scalatra base servlet I think have an implementation of url which was clashing. The url version from Scalatra does not return OK.

First of all inspect type of result. If you use IDE just hover your mouse on it and see what it is actually is. It must be different than Future[String], it is Future[T], find out what is T and how to convert it to String.
