simple proxying

gistfile1.txt

PROBLEM:

The Product Importer has lots of crazy report formats that vary wildly from report to report.  To reduce 
the strain on requiring TWIKI to model these in JSON marshallers/unmarshallers, I have created a happy 
path proxy scenario that just passes along the response of a request.

This is using the NEWMAN framework https://github.com/stackmob/newman.. The TwikiService 
has an existing example of the use of Newman. 

In a route, add something like:

    import spray.http.ContentTypes._
    
    ...

    } ~ path("someproxypath"){
      get{
        complete{
          // url you need to proxy to
          val url = new URL("https://api.github.com/users/mralexgray/repos")
          val resp = Await.result(GET(url).apply, 20.second)
          HttpEntity(`application/json`, resp.bodyString)
        }
      }
    }


You might want to wrap in a future to make this non-blocking. Feel free to modify the route to add auth,
handle non-happy scenarios, etc. But this is the bulk of the work!

    } ~ path("extra"){
      get{
        complete{
          val url = new URL("https://api.github.com/users/mralexgray/repos")
          val resp = Await.result(GET(url).apply, 20.second)
          resp.code match {
            case HttpResponseCode.Ok => HttpEntity(`application/json`, resp.bodyString)
            case _ => throw new Exception("this is a travesty!")
          }

        }
      }
    }

enjoy,
