사용자 노드 아래의 각 사용자에 대한 사용자의 UID에 액세스 할 수있는 방법이 있나요?

목표는 내 클라우드 기능에 다음 코드를 실행하는 것입니다 :

ref = admin.database().ref(`/users/${user.uid}/week1`); 

을하지만 약자로, 다음 클라우드 기능은 사용자가 정의되지 않는다는 오류 반환 :

exports.update = functions.database.ref('/users/{uid}') 
    .onWrite(event=>{ 
ref = admin.database().ref(`/users/${user.uid}/week1`); 
return ref.set(50); 

} 

Answer 1

을

functions.database.ref('/users/{uid}') 

을 그 : 당신은 데이터베이스 트리거에 와일드 카드를 정의 할 때전달 된 이벤트에서 와일드 카드에 액세스 할 수있는 위치는 event.params.uid입니다. 자세한 내용은 documentation을 참조하십시오.
