无法向 Cloud Firestore 发送数据

Question

我正在尝试将一些随机数据推送到 Cloud Firestore。所以，我已经使用带有-firebase init 函数的云函数初始化了项目。 在函数目录中，我有一个文件 seed.js，其中包含发送数据的代码。使用 faker 生成数据。

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);

当我运行 node seed.js 时，我收到了下面描述的错误

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

Answer 1

我假设您正在遵循 fireship.io 中的示例

如果您查看示例，您还必须先初始化 Firebase 配置

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

如果这已经部署到云功能，配置将是automatically provided。如果没有，您将需要提供您的 firesbase 凭据

Answer 2

您需要在文件顶部初始化 firebase 应用

类似这段代码

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