Question

我正在尝试部署我的 firebase 云功能。当我在将函数添加到 index.js 文件后运行 firebase deploy --only functions 时，它给了我上面提到的错误。

这是我的 firebase.json 文件：

  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ],
    "source": "functions"
  },
  "database": {
    "rules": "database.rules.json"
  },
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  }
}

这是我的 index.js 文件：

const functions = require('firebase-functions');
const algoliasearch = require('algoliasearch');
//  get api keys for the algolia from the env variable of cloud functions
const APP_ID = functions.config().algolia.app;
const ADMIN_KEY = functions.config().algolia.key;

//  algolia client
const client = algoliasearch(APP_ID, ADMIN_KEY);
const index = client.initIndex('pals');

//  ADD algolia index from firestore database when a document is created in firestore:
exports.addToIndex = functions.firestore.document('users/{userId}').onCreate(snapshot=>{
  const data = snapshot.data();
  const objectID = snapshot.id;
  //  add objectID to algolia index
  return index.addObject({...data, objectID});
});

//  UPDATE algolia index from firestore database when a document is updated in firestore
exports.updateIndex = functions.firestore.document().onUpdate(change =>{
  //  change.after gives the document after the change
  const newData = change.after.data();
  const objectID = change.id;
  //  update objectID to algolia index
  return index.saveObject({...newData, objectID});
});

//  DELETE algolia index from firestore database when a document is deleted in firestore
exports.updateIndex = functions.firestore.document().onDelete(snapshot =>{
  //  delete objectID to algolia index
  return index.deleteObject(snapshot.id);
});

我尝试使用他们提供的 hello world 代码段运行 firebase deploy --only functions。它工作得很好。

正如错误消息所说，您需要始终将路径传递给 functions.firestore.document(...) 函数，以确定函数在哪些文档路径上触发。

您在此处正确执行此操作：

exports.addToIndex = functions.firestore.document('users/{userId}').onCreate(snapshot=>{
  ...

但是在这两种情况下您没有传递路径：

exports.updateIndex = functions.firestore.document().onUpdate(change =>{
  ...

exports.updateIndex = functions.firestore.document().onDelete(snapshot =>{
  ...

如果您还希望它们在用户文档上触发，就像 onCreate 一样，它们将是：

exports.updateIndex = functions.firestore.document('users/{userId}').onUpdate(change =>{
  ...

exports.updateIndex = functions.firestore.document('users/{userId}').onDelete(snapshot =>{
  ...

错误：“路径”参数必须是字符串类型。收到未定义。 firebase deploy --only 功能
