如何从 Google Sheets 访问 Cloud Firestore?

问题描述

我正在尝试借助 FirestoreGoogleAppsScript 示例从 Google 工作表访问 Cloud Firestore 数据库，但是如第 5 点所述，我已经下载了文件，但没有找到更新项目中 client_email、private_key 和 project_id 的位置.所以请指导我继续前进.

I am trying to access Cloud Firestore database from Google sheet with the help of FirestoreGoogleAppsScript example, but as explained in the 5th point I have downloaded the file but not getting where to update the client_email, private_key and project_id in the project.So kindly guide me to move forward.

当您按下创建"时，您的浏览器将下载一个 .json 文件，其中包含您的私钥 (private_key)、服务帐户电子邮件 (client_email) 和项目 ID (private_key)>project_id).将这些值复制到您的 Google Apps 脚本中 - 您需要它们来通过 Firestore 进行身份验证.

When you press "Create," your browser will download a .json file with your private key (private_key), service account email (client_email), and project ID (project_id). Copy these values into your Google Apps Script — you'll need them to authenticate with Firestore.

带有演示代码.gs

function myFunction() {
  projectid: "xxx";
  key: "-----BEGIN PRIVATE KEY-----
PrivateKeyHere
-----END PRIVATE KEY-----
";
  email: "[email protected]";

  var firestore = FirestoreApp.getFirestore(email, key, projectId);
}

错误

ReferenceError: "email" is not defined. (line 7, file "Code")

推荐答案

你必须做如下，例如在一个简单的函数中获取一个集合:

You have to do as follows, for example in a simple function that fetches a collection:

function fecthFirstCollectionDocs() {

  var email = "[email protected]";
  var key = "-----BEGIN PRIVATE KEY-----your key here
-----END PRIVATE KEY-----
";
  var projectId = "zzzzzzzzz";

  var firestore = FirestoreApp.getFirestore(email, key, projectId);

  const allDocuments = firestore.query("FirstCollection").execute();
  Logger.log(JSON.parse(allDocuments));

}

key 的值是通过创建服务帐户获得的，如库文档中所述:https://github.com/grahamearley/FirestoreGoogleAppsScript#creating-a-service-account.很简单，按照说明操作即可.

The value of key is obtained by creating a service account, as explained in the Library documentation: https://github.com/grahamearley/FirestoreGoogleAppsScript#creating-a-service-account. It's quite easy, just follow the instructions.

你只需要复制-----BEGIN PRIVATE KEY-----和-----END PRIVATE KEY-----之间的部分----- 来自 .json 文件.

You have to copy only the part between -----BEGIN PRIVATE KEY----- and -----END PRIVATE KEY----- from the .json file.

根据您 4 月 9 日的评论进行

Edited following you comment of 9 April:

解决

ReferenceError: "email" is not defined. (line 7, file "Code")

错误，您应该正确声明传递给 getFirestore() 方法的变量，如我回答的代码所示，如​​下所示:

error you should correctly declare the variables you pass to the getFirestore() method, as shown in the code of my answer, and as follows:

而不是做

  projectid: "fir-79c39";

你应该这样做

  var projectid = "fir-79c39";

您声明一个名为 projectid 的变量，您在 getFirestore() 方法中使用该变量.key 和 email 相同.

You declare a variable named projectid that you use in the getFirestore() method. The same for key and email.
