I'm making a service to send notify to my web application through Firebase, here is my code:
@Override
public String sendPushNotification() throws IOException {
String result = "";
URL url = new URL(Constants.FIREBASE_API_URL);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization", "key=" + Constants.FIREBASE_SERVER_KEY);
conn.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3)" +
" AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36");
JSONObject json = new JSONObject();
Notification notification = notificationRepository.getFirstByOrderByIdDesc();
AssignTask assignTask = assignTaskService.getAssignTask(notification.getTaskId());
try {
json.put("to", accountService.findByEmployeeId(assignTask.getAssignerId()).getTokenFirebase().trim());
JSONObject data = new JSONObject();
data.put("sender", employeeService.getDetailEmployee(assignTask.getAssigneeId()).getFullName());
data.put("task_id", notification.getTaskId());
json.put("data", data);
JSONObject info = new JSONObject();
info.put("title", notification.getLabel());
info.put("body", notification.getContent());
System.out.println(notification.getContent());
info.put("message", "");
json.put("notification", info);
} catch (JSONException e1) {
e1.printStackTrace();
}
try {
System.out.println(json.toString());
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(json.toString());
wr.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
result = "succcess";
} catch (Exception e) {
e.printStackTrace();
result = "failure";
}
System.out.println("FCM Notification is sent successfully");
return result;
}
When I debug, here is the json value
{"notification":{"title":"Báo cáo công việc","body":"đã gửi báo cáo về công việc có ID = ","message":""},"data":{"sender":"Đen Vâu","task_id":35},"to":"cAwBXnEql-A:APA91bF2R1iIugxiIT9iR8NtNGoeOGXLHAdCbf07ukJ0Rjp6MjJb3nTrP9X1W6ZBj-MWWa6WnpVRVC3EXqPdiGi--kN5tmFySgo8IlN9Vq2_-DxNx7T4jiYgeXf9hDdBpkrboNjWtGe4"}
But the message send to Firebase is in wrong format, I put an System.out.println() and it showed this:
{"notification":{"title":"Báo cáo công vi?c","body":"?ã g?i báo cáo v? công vi?c có ID = ","message":""},"data":{"sender":"?en Vâu","task_id":35},"to":"cAwBXnEql-A:APA91bF2R1iIugxiIT9iR8NtNGoeOGXLHAdCbf07ukJ0Rjp6MjJb3nTrP9X1W6ZBj-MWWa6WnpVRVC3EXqPdiGi--kN5tmFySgo8IlN9Vq2_-DxNx7T4jiYgeXf9hDdBpkrboNjWtGe4"}
I tried to many ways but it still no help. Anyone know why? I think this is an issue with UTF-8 of Spring Boot. I'm using Spring Boot and Gradle
