我正在嘗試運行腳本,但是我執行的步驟不起作用。 我哪里出問題了?

[英]I am trying to run a script but the steps I have taken are not working. Where have I gone wrong?

我正在嘗試運行Maciej Caputa編寫的腳本,此處顯示為答案: 如何將CSV或JSON導入 Firebase Cloud Firestore

我的目標是使用JSON文件將數據上傳到Cloud Firestore,我是運行腳本的新手,所以如果有人可以向我指出如何運行此腳本的方向,我在下面概述了我嘗試過的步驟。 我哪里做錯了?

到目前為止我嘗試過的是:

  1. 我已將腳本代碼保存在一個文本文件中。

  2. 我用數據庫的URL填寫了DatabaseURL代碼行。

  3. 我已經使用終端安裝了node和nom。

  4. 在終端中,我做了:sudo(腳本文件的路徑)

  5. 然后做了:節點(子文件的路徑>)

但這沒有用。

const admin = require('../functions/node_modules/firebase-admin');
const serviceAccount = require("./service-key.json");

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://<your-database-name>.firebaseio.com"
});

const data = require("./fakedb.json");

/**
 * Data is a collection if
 *  - it has a odd depth
 *  - contains only objects or contains no objects.
 */
function isCollection(data, path, depth) {
  if (
    typeof data != 'object' ||
    data == null ||
    data.length === 0 ||
    isEmpty(data)
  ) {
    return false;
  }

  for (const key in data) {
    if (typeof data[key] != 'object' || data[key] == null) {
      // If there is at least one non-object item in the data then it cannot be collection.
  return false;
}
  }

  return true;
}

// Checks if object is empty.
function isEmpty(obj) {
  for(const key in obj) {
    if(obj.hasOwnProperty(key)) {
      return false;
    }
  }
  return true;
}

async function upload(data, path) {
  return await admin.firestore()
    .doc(path.join('/'))
    .set(data)
    .then(() => console.log(`Document ${path.join('/')} uploaded.`))
    .catch(() => console.error(`Could not write document ${path.join('/')}.`));
}

/**
 *
 */
async function resolve(data, path = []) {
  if (path.length > 0 && path.length % 2 == 0) {
    // Document's length of path is always even, however, one of keys can actually be a collection.

// Copy an object.
const documentData = Object.assign({}, data);

for (const key in data) {
  // Resolve each collection and remove it from document data.
  if (isCollection(data[key], [...path, key])) {
    // Remove a collection from the document data.
    delete documentData[key];
    // Resolve a colleciton.
    resolve(data[key], [...path, key]);
  }
}

// If document is empty then it means it only consisted of collections.
if (!isEmpty(documentData)) {
  // Upload a document free of collections.
  await upload(documentData, path);
}
  } else {
    // Collection's length of is always odd.
    for (const key in data) {
      // Resolve each collection.
      await resolve(data[key], [...path, key]);
    }
  }
}

resolve(data);

對於第5步,您需要提供要使用node執行的文件的路徑。 它應該類似於node yourFileName.js
