Hello again,
I have change my code to the following, but for some reason it returns
java.net.NoRouteToHostException: No route to host
for any URL I try as FCM_URL value below:
private static final HttpClient sHttpClient = new HttpClient();
private static final BufferingResponseListener sFcmListener = new BufferingResponseListener() {
@Override
public void onComplete(Result result) {
if (!result.isSucceeded()) {
System.err.println(result.getFailure()); // No route to host
return;
}
String body = getContentAsString(StandardCharsets.UTF_8);
System.out.printf("onContent: %s\n", body);
Map<String, Object> resp = (Map<String, Object>) JSON.parse(body);
try {
Object[] results = (Object[]) resp.get(FCM_RESULTS);
Map map = (Map) results[0];
String error = (String) map.get(FCM_ERROR);
if (FCM_NOT_REGISTERED.equals(error)) {
// TODO delete invalid FCM token from the database
}
} catch (Exception ex) {
System.err.println(ex);
}
}
};
public static void main(String[] args) throws Exception {
sHttpClient.start();
sHttpClient.POST(FCM_URL)
.header(HttpHeader.AUTHORIZATION, FCM_KEY)
.header(HttpHeader.CONTENT_TYPE, "application/json")
.content(new StringContentProvider(JSON.toString(REQUEST)))
.send(sFcmListener);
}
Any suggestions please?
