admin.firestore(...).document在导出时不起作用 [英] admin.firestore(...).document is not a function at exports

问题描述

我正在运行由Firebase实时数据库更改触发的云功能并更新FireStore.但是，尽管该函数触发了，但该函数无法访问Firestore.

I am running a cloud function that is triggered by a firebase realtime database change and updates FireStore. However, although the function triggers, the function cannot access the Firestore.

exports.reveal = functions.database.ref('/reveals/{postIDthatWasRevealed}/revealed').onUpdate((change, context) => {
const revealedValue = change.after.val()

if (revealedValue === true) {
   var updates = {}
   const postID = context.params.postIDthatWasRevealed
   return admin.firestore().document('/posters/' + postID).get().then(querySnapshot => {

这时，控制台日志指出 TypeError:admin.firestore(...).document不是函数.我已经尝试过此答案:尝试答案，但问题仍然存在.这是否与我正在访问Firebase云功能内部的firestore有关?我的云功能是否没有正确更新?

At this point, the console log states TypeError:admin.firestore(...).document is not a function at.. I have already tried this answer :Tried Answer But the problem continues. Does this have to do with the fact that I am accessing firestore inside of firebase cloud function? Are my cloud functions not properly updated?

编辑(包括初始化代码)

Edit (Includes Initialization code)

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

此外，我尝试通过将功能更改为来调试该功能:

In addition, I have tried to debug the function by changing it to :

if (revealedValue === true) {
   var updates = {}
   const postID = context.params.postIDthatWasRevealed

   return admin.firestore()

现在，当我触发函数时，我得到函数执行耗时811 ms，状态为:"ok" 因此，似乎firestore函数是有效的，只是我的语法可能离开，或者我可能会忘记一些东西

Now, when I trigger the function, I get Function execution took 811 ms, finished with status: 'ok' Thus, it seems as if the firestore function is valid, just that my syntax may be off or I may be forgetting something

推荐答案

使用 doc()函数代替 document()
