设置内容/媒体类型 - Restlet

Question

How do you set the content type in Restlet (version 2.0 for google app engine)? In this case, I'd like to set the content type to ""text/xml".

I have:

public class SubResource  extends ServerResource {

 @Get
 public Representation get(Representation representation){

    setStatus(Status.SUCCESS_OK);
    StringRepresentation sr = new StringRepresentation(getSomeXml());

    return sr;
 }
}

I'm unsure even if it is a value that is set in the Representation, or if it is set from the ServerResource class the same way that the return code is.

ANSWER:

    StringRepresentation sr = new StringRepresentation(getSomeXml());
    sr.setMediaType(MediaType.TEXT_XML);

Answer 1

Unless there is something in the GAE style that I don't know about, I don't think it needs to be that complicated. This works for me:

 @Get( value = "xml" )
 public String myMethodNameHere(){
    return getSomeXml();
 }

Answer 2

If you're using annotations you could do

@Get("txt")
public Representation get() {

    setStatus(Status.SUCCESS_OK);

    return new StringRepresentation("Hi");
 }

See Get and MetadataService .

Copying this from some code I wrote a while ago, not sure if things have changed since:

Representation representation = new StringRepresentation(body, MediaType.TEXT_PLAIN);
representation.setCharacterSet(CharacterSet.UTF_8);
return representation;

For your needs, there's also MediaType.TEXT_XML

Answer 4

The "aha!" here, is that the function must return a Representation().

Thie will work most of the time, but in certain browsers it will return 404 with content.

getResponse().setEntity(rep);
getResponse().getEntity().setModificationDate(date);
getResponse().setStatus(Status.SUCCESS_OK);

This will show content AND a 200 status code:

getResponse().setEntity(rep);
getResponse().getEntity().setModificationDate(date);
getResponse().setStatus(Status.SUCCESS_OK);
return rep;

Answer 5

Annotation didn't work for me. I set the content type explicitly.

@Get
public Representation represent() {
    StringRepresentation sr = new StringRepresentation("xml string..");
    sr.setMediaType(MediaType.APPLICATION_XML);
    return sr;
}
