Hi there
I am trying to make a REST call through HTTPS and read the response
headers. Even though the response text (response.getText()) has
absolutely no problem, getHeaders() throws a NullPointerException:
java.lang.NullPointerException: null
at com.google.gwt.http.client.Request.getHeaders(Request.java:88)
at com.google.gwt.http.client.Request.access$0(Request.java:86)
at com.google.gwt.http.client.Request$1.getHeaders(Request.java:
53)
at com.bc.adminconsole.client.shared.core.services.ServiceBase
$1.onResponseReceived(ServiceBase.java:76)
at
com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java:
287)
at com.google.gwt.http.client.RequestBuilder
$1.onReadyStateChange(RequestBuilder.java:395)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:
39)
My code is mostly like this (RestService creates a RequestBuilder when
calling ()).
RestService restService = new RestService(requestUri, requestMethod,
requestBody, authToken);
RequestCallback r = new RequestCallback() {
@Override
public void onResponseReceived(Request request, Response response) {
int responseStatusCode = response.getStatusCode();
if (responseStatusCode != Response.SC_OK && responseStatusCode
!=
Response.SC_CREATED) {
// ... stuff ...
} else {
headers = response.getHeaders();
T result = reader.read(response.getText());
resultCallback.onSuccess(result);
}
}
// ... stuff ...
};
restService.setCallback(r);
restService.send();
Any ideas why getHeaders() would return null even though my request
has statusCode 201 and everything else is OK?
Thank you!
