Question

我已经编写了下面的代码，以检测何时将注释添加到数据库，然后通过更新时间轴节点进行响应，问题是它实际上并未更新。 为什么不起作用？

    export const onCommentAdded = functions.database
.ref('/Comments/{receiverUID}/{postID}/{mediaNum}/{commentID}')
.onCreate((snapshot, context) => {
  const uid = context.params.uid
  const newCommentUID = snapshot.child("UID").val()
  console.log(newCommentUID, " the comment")
  return addNewCommentNotif(uid, newCommentUID) 
})

function addNewCommentNotif(uuid: string, newCommentUID: string) {

  //NotifTimeline/uid/NewNotif (someuniqueVal)/commentID
  const randID = Math.floor(100000000 + Math.random() * 900000000);
  const notifTimelineRef = admin.database().ref("NotifTimeline").child(uuid).child(newCommentUID + ":" + randID).child("NewComment")

  notifTimelineRef.set(newCommentUID)//update
  .then(() => {
    console.log("Success updating this uid comment timeline")
  })
  .catch((error: string) => {
    console.log("Error in catch: "+error)
    response.status(500).send(error)
  })
  return Promise.resolve();
}

返回set（）返回的承诺：

function addNewCommentNotif(uuid: string, newCommentUID: string) {

  //NotifTimeline/uid/NewNotif (someuniqueVal)/commentID
  const randID = Math.floor(100000000 + Math.random() * 900000000);
  const notifTimelineRef = admin.database().ref("NotifTimeline").child(uuid).child(newCommentUID + ":" + randID).child("NewComment")

  return notifTimelineRef.set(newCommentUID)//update
  .then(() => {
    console.log("Success updating this uid comment timeline")
  })
  .catch((error: string) => {
    console.log("Error in catch: "+error)
    response.status(500).send(error)
  })
}

ToraCode在他说的话中正确地说：

我认为是因为您的const uid = context.params.uid。我在您的引用中看不到任何参数名称uid
