推荐答案

此问题已通过以下方式解决:

The problem was solved this way:

将下载的.json文件保存在路径"./your project path/functions"中.

Save the downloaded .json file in the path "./your project path/functions".

将此代码添加到index.js的顶部:

Add this code to the top of your index.js:

var serviceAccount = require("./[downloaded file name].json");

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),
    databaseURL: "https://[your project id].firebaseio.com"
});
