typescript - Firestore 查询中的 Client SDK 和 Admin SDK 差异

问题描述

在 Firebase Functions 中运行查询时，我无法正常工作。它在客户端完美运行，但在函数中却不行。想知道是否有办法让它与 Admin SDK 一起工作。我的查询做错了什么？

参数：

searchQuery = {
  start:
    "[native Date Fri Feb 08 2019 00:00:00 GMT+0200 (Itä-Euroopan normaaliaika)]",
  end:
    "[native Date Fri Feb 08 2019 23:59:59 GMT+0200 (Itä-Euroopan normaaliaika)]",
  cafeIds: ["LI088001"],
  textSearch: "",
  time: { time: "00-24", label: "Kokopäivä" }
}

sort = {
  "column": "created",
  "value": "asc"
}

询问：

let ref = firestoreDB.collection('events')
ref = ref.where('created', '>=', searchQuery.start).where('created', '<=', searchQuery.end)

for (const cafe of searchQuery.cafeIds) {
  ref = ref.where('cafeId', '==', cafe)
}

ref = ref.where(`time.${searchQuery.time.time}`, '==', true)

if (searchQuery.textSearch !== '') {
  ref = ref.where(
    'products.',
    'array-contains',
    lowerCase(searchQuery.textSearch)
  )
}

if (sort.field === 'created') {
  ref = ref.orderBy('created', sort.value)
} else if (sort.field === 'productCount') {
  ref = ref
    .orderBy('created', 'asc')
    .orderBy('productCount', sort.value)
} else if (sort.field === 'total') {
  ref = ref
    .orderBy('created', 'asc')
    .orderBy('total', sort.value)
} else {
  ref = ref.orderBy('created', 'asc').orderBy('eventId', 'asc')
}
const query = await ref.limit(10).get()

将相同的代码放入用 typescript 编写的函数时，出现以下错误：

src/storage/exportCsv.f.ts:25:5 - error TS2322: Type 'Query' is not assignable to type 'CollectionReference'.
  Property 'id' is missing in type 'Query'.

解决方案

看起来您在 Admin SDK 中遇到了一些 TypeScript 错误。因此，要么您没有在客户端 JavaScript 中使用 TypeScript，要么服务器上的编译器更加严格。无论哪种方式，您都需要解决每个问题，或者也切换到在 Cloud Functions 中使用纯 JavaScript。

有很多错误，但最常见的错误似乎是：

类型“查询”不可分配给类型“CollectionReference”。

28       ref = ref.where('cafeId', '==', cafe)

你先在这里定义ref：

let ref = firestoreDB.collection('events')

由于collection('events) 返回一个CollectionReference,ref成为该类型。然后当您稍后尝试分配ref.where('cafeId', '==', cafe)给它时，它是类型Query（的祖先CollectionReference）。所以这是一个类型错误。

解决方案是立即制作ref类型Query：

let ref: Query = firestoreDB.collection('events')
