Background : I'm calling backend WebServices from Play controller
and sending the Response
(in JSON format) to AngularJS module wrapped in play.mvc.Result
. This integration works seamlessly.
Problem Statement : Now I want to parse the Response
and use it for some business logic; but play.mvc.Result
class has only one method which is toScala()
. How do I get the body of play.mvc.Result
. Can I use play.libs.F.Promise
to get my job done?
Below is the Generalized code which takes JSON request body and Service URL as parameter and returns the play.mvc.Result
.
WSRequestHolder requestHolder = WS.url("https://application.url/ws/endpoint")
.setHeader("Content-Type", "application/json");
final Promise<String> promise = requestHolder.post(jsonRequest)
.map(new Function<WS.Response, String>() {
@Override
public String apply(final Response a) throws Throwable {
//Do i need to Parse from here???
return a.getBody();
}
});
return Results.async(promise.map(new Function<String, Result>() {
@Override
public Result apply(final String a) throws Throwable {
if(STR_UNAUTHORIZED.equals(a)){
return Results.redirect(controllers.routes.Authentication.login("",""));
}
return Results.ok(a);
}
}));
So is there a way to extract the Response
body from play.mvc.Result
or is there any alternate way to do this?
Below code would Parse the response from WebService call in synchronized way:
WSRequestHolder requestHolder = WS.url("https://application.url/ws/endpoint")
.setHeader("Content-Type", "application/json");
final Promise<WS.Response> promise = requestHolder.get();
Response myResponse=promise.get(50000);
// This code returns the Parsed response in form of String
return myResponse.getBody();
