Hi, i have problem by using gwt requestbuilder to make http request
with json object in body messages. In the server side code, i use php,
but when i try to access request's data, the $_POST variable is empty.
I post the code below:
String path = GWT.getHostPageBaseURL() + "JsonObjectReceiver.php";
RequestBuilder trasmettiJSON = new
RequestBuilder(RequestBuilder.POST, URL.encode(path));
trasmettiJSON.setHeader("Content-Type",
"application/json");
//L'evento contiene due oggetti da tenere in
considerazione
PrenotazioneJSON pj =
event.getData(Costanti.OGGETTI_DA_INVIARE);
final WCard corrente =
event.getData(Costanti.CARD_CORRENTE_PASSO3);
try{
@SuppressWarnings("unused")
Request req =
trasmettiJSON.sendRequest(pj.getInfo_generali(), new
RequestCallback() {
@Override
public void onResponseReceived(Request
request, Response
response) {
if (200 ==
response.getStatusCode()) {
AppEvent xmlCorrect =
new AppEvent(StartEvents.xmlWritten);
xmlCorrect.setData(Costanti.CARD_CORRENTE_PASSO3, corrente);
xmlCorrect.setData("status", response.getText());
forwardToView(passo3View, xmlCorrect);
} else {
// displayError("Couldn't retrieve
JSON (" +
response.getStatusText()+ ")", corrente);
}
}
@Override
public void onError(Request request,
Throwable exception) {
//displayError("Couldn't
retrieve JSON");
}
});
}catch(RequestException e) {
//displayError("Couldn't retrieve JSON");
}
CAN SOMEONE HELP ME PLEASE? I'M NEW TO GWT, SO I HAVE NOT A LOT OF
EXPERIENCE.
THANKS IN ADVANCE FOR ANSWERS
ALESSIO
