如何将此 JSON 文件导入 Firestore 数据库？答案

【问题标题】：How to import this JSON file into Firestore database?如何将此 JSON 文件导入 Firestore 数据库？
【发布时间】：2019-02-02 20:58:40
【问题描述】：

我已经使用 Google Firebase 设置了身份验证过程。我现在希望开始使用 Firestore 数据库 - 因为我需要使用多个集合 - 并且 JSON 文件中有大量数据需要导入。

JSON 文件如下所示。我将只发布前两个条目，但总共有 60 个，而且我自己也无法输入。

如果有人可以指导我完成有关如何利用脚本解决此问题的步骤，将不胜感激。谢谢！

我曾尝试利用 Stack 上的其他一些帖子，但正是脚本的使用让我大吃一惊。

【问题讨论】：

使用 firebase，您可以将您的 json 对象传递给 update 方法，然后它就会写入它。问题出在哪里？
@Mocas 你能解释一下吗？我当前的程序中有一个 JSON 文件，我正在使用 Firebase 的 Firestore。

标签： reactjs firebase google-cloud-firestore

【解决方案1】：

我在编写代码时遇到了同样的问题。对于将 JSON 导入您的 firebase 数据库，没有特定的方法，但您可以通过脚本插入它。为此，我制作了这个脚本。这也可能对您有所帮助。

const fcm = require('nodefire-realtime');

//For Initialize Firebase DB
let serviceAccountKey = require("./serviceAccountKey.json");
let dbUrl = "https://<Your-project-id>.firebaseio.com/";
fcm.init(dbUrl, serviceAccountKey);

const data = require('./<your-JSON-file-name>.json');

//For insert
let dbReference = 'data/user/';
let data =data;
fcm.insert(data, dbReference);

只需制作一个简单的 JS 文件 e.g. app.js 并将上面的代码粘贴到它上面。您可以从项目设置（firebase）中获取 serviceAccountKey.json。如果你被这个包卡住了，请按照nodefire-realtime 中的步骤操作。我希望这会有所帮助。
