In spray how to unmarshall plain/text?

Question

Can anybody show me an example in spray how to unmarshall POST with content type plain/text ?

How to write the route?

Thanks!

Answer 1

This is how the route would look like:

  post {
    entity(as[String]) { str =>
      complete(str)
    }
  }

A sample request would be:

curl -X POST -d 'It works' localhost:8080

which echoes back the POST data.

To get the whole sample app use this official template and add/edit the route.

If you want to understand how it works in detail see this doc and this one.

Thanks for your answer, I tried this piece of code together with github.com/mhamrah/spray-sample, and I got the message "Expected 'application/json'", it seems that some setting need be done. Can you kindly explain to me? Thanks so much! – Thornberry

please try this in a service without JSON support, i.e. not in that project. It seems that JSON unmarshaller takes over all conversions and sets the expected media type to json. I'll try to give a better explanation soon when I find some time ;). Here is a good template to start with: github.com/spray/spray-template – Lodestone

Yes, you need to be careful with importing SprayJsonSupport._ etc. Optimally, you just import it exactly in the scopes where you need it and not globally for the file which contains all of your routes. – Adjutant

Any idea why in akka http string implicit is not always available? see groups.google.com/forum/#!topic/akka-user/p-m1eKm3-YM – Seclude
