Re: [Resteasy-developers] java.lang.String JSON formated

[Morch, H. <hol...@na...>]

Hi again,



I think returning a valid json string in the method is not a good resolution. Separating the creation of the content from the marshaling is a quit good idea. Returning JSON in the method would break this. What if I want to support different content types depending on the accept header?



e.g.

@GET

@Produces({"application/json","text/plain"})

String get() {



     return "Hello World";

}



If someone want just the string, he can send "Accept text/plain" and gets "Hello World" (without the quotes). But if I want to eval the result with a JavaScript processor e.g. in a browser, I want something which the browser can handle.

Jslint may be a reference, but I ran three short tests with Firefox:

- eval("Hello World "); --> SyntaxError

- eval("\"Hello World\""); --> Works: "Hello World"

- eval("\"Hello World\""); --> Works too: "Hello World"

Note: All three versions fail on Jslint.

So if someone sends "Accept application/json" a JSON marshaller like Jackson can produce either ""Hello World"" or "{"Hello World"}" and this can be run with eval.



Just my two cents.



Kind regards,

Holger
