I follow the example code provided by Google GWT to send a HTTP GET
request and receive the response. The GET request was sent out
successfully, but can't receive response message. Actually the
response message has been sent back, according to Wireshark trace.
Does anybody know why?
String urlCityList = "http://www.abcdeft.com/abc/def";; // Here is
just a fake url, but I used real url when trouble shooting.
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode(urlCityList));
try {
Request request = builder.sendRequest(null, new
RequestCallback() {
public void onError(Request request, Throwable exception) {
}
public void onResponseReceived(Request request, Response
response) {
//
Window.alert(Integer.toString(response.getStatusCode())); // I tried
to print out the status code.It's 0, means nothing is received. But
actually I can see the response message in wireshark tracing.
Window.alert("Could not get HTTP response."); // The
code
goes to this branch.
//Window.alert(response.getText());
if (200 == response.getStatusCode()) {
text = response.getText();
parseMessage(response.getText());
//text = response.getStatusText();
} else {
//Window.alert(response.getStatusText());
//Window.alert(Integer.toString(response.getStatusCode()));
}
}
});
} catch (RequestException e) {
}
}
