webpush-java: Error 400 UnauthorizedRegistration
I use this code:
import java.nio.charset.StandardCharsets;
import java.security.Security;
import org.apache.commons.io.IOUtils;
import org.apache.http.HttpResponse;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import com.google.gson.JsonObject;
import nl.martijndwars.webpush.Notification;
import nl.martijndwars.webpush.PushService;
public class Teste {
public static void main(String[] args) {
try {
Security.addProvider(new BouncyCastleProvider());
// Send notification!
sendPushMessage(getPayload());
} catch (Exception e) {
e.printStackTrace();
}
}
private static final int TTL = 255;
public static void sendPushMessage(byte[] payload) {
// Figure out if we should use GCM for this notification somehow
try{
Notification notification;
PushService pushService;
// Create a notification with the endpoint, userPublicKey from the subscription and a custom payload
notification = new Notification(
"https://fcm.googleapis.com/fcm/send/d8KX2q4goDM:APA91bH5Boq0076mY4-YdxIOrsD_pzfx6DorrD6FRaksk5sf64A3Z9cySX2JhxwOlql1wq-Bdo0SZvSmBbARZaxTgn4_O9MHbbG_JFY-ZJp0i6WauLwllglA54lBp6NkWB0q6axNHIa3",

"nJiZotPSQE4P4z75Igq57Q==",
"Hello, world!"
);
// Instantiate the push service, no need to use an API key for Push API
pushService = new PushService();
// Send the notification
HttpResponse httpResponse = pushService.send(notification);
System.out.println(httpResponse.getStatusLine().getStatusCode());
System.out.println(IOUtils.toString(httpResponse.getEntity().getContent(), StandardCharsets.UTF_8));
} catch (Exception e) {
e.printStackTrace();
}
}
private static byte[] getPayload() {
JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("title", "Hello");
jsonObject.addProperty("message", "World");
return jsonObject.toString().getBytes();
}
}
And receive this answer:
400

I’m glad you got this to work @dsteen338! I’d be happy to discuss ideas that could improve the wiki. PRs that improve the documentation are very welcome.
It seems that most comments on this issue are about problems with using the library and not with the library itself, so I will close the issue now. If someone bumps into a similar issue or wants to discuss improvements to the documentation, please create a new issue.
Scratch that! I got it to work, I just needed to un-register and re-register the service worker after adding the
applicationServerKeyto the subscription.My comment now becomes, that I needed to do a lot of googling and investigating to get to this point and get it working. I needed to find this thread specifically and use the example from https://github.com/MartijnDwars/spring-boot-web-push instead of the one from the Usage example in the wiki: https://github.com/web-push-libs/webpush-java/wiki/Usage-Example , I’m wondering if it might be of use to people who end up in a similar situation as me to update the wiki accordingly.
I figured it out: the payload cannot be a string like the one in the above code. It must be a json in a certain format. At least:
{ “notification”: {“title”: “message title”, “body”: “message body”} }
Now it is ok!
Thanks a lot @MartijnDwars. thanks to your example I understood what was wrong with my code. After tests of changing keys, I did not updated the public key in the javascript file, and it was different from the server one. Now it works 😃
