[Refact] FCM 토큰 전송 유형 변경

[psy-choi]

목표

FCM 토큰이 잘 보내지지 않음

sendFCM = messaging.Message(
        data = {
            "data" : {
            "userId" : str(userId),
            "peopleNumber" : str(peopleNumber)},
            "type" : "data"
        },
        token = userToken
    )
    response = messaging.send(sendFCM)

해당 코드에서 오류 발견 후 리팩토링 진행하고 함

이러한 오류가 떴는데, 즉 FCM data는 하나의 json으로 전송될 수는 있지만, key의 값은 무조건 string이어야 한다는 내용이다.

• firebaseService.py

  
  sendFCM = messaging.Message(
      data = {
          "userId" : str(userId),
          "peopleNumber" : str(peopleNumber),
          "type" : "data"
      },
      token = userToken
  )
  response = messaging.send(sendFCM)

이때 userId와 PeopleNumber을 data 속에 넣어주어야 하고, 심지어 peopleNumber 또한 str 값으로 변경해주어야 했다.

이렇게 하니까 잘 나오는 것을 볼 수 있었다.
