FileUploadSupport

trait FileUploadSupport extends ScalatraKernel

FileUploadSupport can be mixed into a org.scalatra.ScalatraFilter or org.scalatra.ScalatraServlet to provide easy access to data submitted as part of a multipart HTTP request. Commonly this is used for retrieving uploaded files.

Once the trait has been mixed into your handler you can access any files uploaded using

fileParams("myFile")

where myFile is the name of the parameter used to upload the file being retrieved.

fileParams("myFile") }}} of the parameter used to upload the file being retrieved.

Note

Once any handler with FileUploadSupport has accessed the request, the fileParams returned by FileUploadSupport will remain fixed for the lifetime of the request.

  33. def get(routeMatchers: RouteMatcher*)(action: ⇒ Any): Route

    The Scalatra DSL core methods take a list of org.scalatra.RouteMatcher and a block as the action body.

    The Scalatra DSL core methods take a list of org.scalatra.RouteMatcher and a block as the action body. The return value of the block is rendered through the pipeline and sent to the client as the response body.

    See org.scalatra.ScalatraKernel.renderResponseBody for the detailed behaviour and how to handle your response body more explicitly, and see how different return types are handled.

    The block is executed in the context of a CoreDsl instance, so all the methods defined in this trait are also available inside the block.

    get("/") {
      <form action="/echo">
        <label>Enter your name</label>
        <input type="text" name="name"/>
      </form>
    }
    
    post("/echo") {
      "hello {params('name)}!"
    }

    ScalatraKernel provides implicit transformation from boolean blocks, strings and regular expressions to org.scalatra.RouteMatcher, so you can write code naturally.

    get("/", request.getRemoteHost == "127.0.0.1") { "Hello localhost!" }
