無法將數據發送到Cloud Firestore

Question

我正在嘗試將一些隨機數據推送到Cloud Firestore。 因此，我已使用帶有-firebase init函數的雲函數初始化了該項目。 在函數dir中，我有一個seed.js文件，其中包含發送數據的代碼。 使用fakerr生成數據。

const faker = require("faker");

const db = admin.firestore();

const fakeIt = () => {
  return db.collection("customers").add({
    username: faker.internet.userName(),
    avatar: faker.internet.avatar(),
    bio: faker.hacker.phrase()
  });
};

Array(20)
  .fill(0)
  .forEach(fakeIt);

當我運行節點seed.js時，出現以下錯誤

PS C:\Users\Ghost\Random Projects\Algolia\functions> node .\seed.js

Answer 1

我假設您正在遵循fireship.io中的示例

如果您查看示例，則還必須首先初始化Firebase配置

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

如果已將其部署到雲功能，則將自動提供配置 。 如果不是，則需要提供您的firesbase憑據

Answer 2

您需要在文件頂部初始化firebase應用

類似於這段代碼

admin.initializeApp(Object.assign({}, functions.config().firebase, {
    credential: admin.credential.cert(serviceAccount),
}));
