Javascript 使用node.js web服务器写入Firebase数据库-“；FIREBASE警告：设置为。。。失败：权限“被拒绝”；

我有一个node.js web服务器，我正试图通过它写入Firebase。但是，无论何时运行，我都会收到以下错误消息：

FIREBASE WARNING: set at /mydb failed: permission_denied 

以下是我如何设置我的应用程序（相关详细信息）：

调用函数：

//what details looks like:
//{ title: 'Details',
  //description: 'Really fast, and awesome.',
  //tags: 'tag-1' 
//}

exports.postDetails = (req, res, next) => {
  writeData(req.body);

  const errors = req.validationErrors();

  if (errors) {
    req.flash('errors', errors);
    return res.redirect('/example');
  } 

  req.flash('success', { msg: 'Success!' });    
  res.redirect('/example');    
};

//what details looks like:
//{ title: 'Details',
  //description: 'Really fast, and awesome.',
  //tags: 'tag-1' 
//}

exports.postDetails = (req, res, next) => {
  writeData(req.body);

  const errors = req.validationErrors();

  if (errors) {
    req.flash('errors', errors);
    return res.redirect('/example');
  } 

  req.flash('success', { msg: 'Success!' });    
  res.redirect('/example');    
};

为了让Firebase接受我的帖子，我需要做什么？我已经阅读了一些关于这方面的文件：

您完成firebase sdk设置了吗？ 您需要下载一个JSON文件，并将其放入节点服务器。 然后使用此代码初始化firebase

var admin = require("firebase-admin");

var serviceAccount = require("path/to/serviceAccountKey.json");

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  apiKey: "8oc57xxx",
  authDomain: "example-04.firebaseapp.com",
  databaseURL: "https://example-ex04.firebaseio.com",
  projectId: "example-ex04",
  storageBucket: "example-ex04.appspot.com",
  messagingSenderId: "5022"
});

function writeData(details) {
  admin.database().ref('mydb/').push({
    title: details.title,
    description: details.description,
    tags: details.tags
  }).then(function() {
    console.log('Upload succeeded');
  }).catch(function(error) {
    console.log('Upload failed');
  });;
}

调用函数：

//what details looks like:
//{ title: 'Details',
  //description: 'Really fast, and awesome.',
  //tags: 'tag-1' 
//}

exports.postDetails = (req, res, next) => {
  writeData(req.body);

  const errors = req.validationErrors();

  if (errors) {
    req.flash('errors', errors);
    return res.redirect('/example');
  } 

  req.flash('success', { msg: 'Success!' });    
  res.redirect('/example');    
};

//what details looks like:
//{ title: 'Details',
  //description: 'Really fast, and awesome.',
  //tags: 'tag-1' 
//}

exports.postDetails = (req, res, next) => {
  writeData(req.body);

  const errors = req.validationErrors();

  if (errors) {
    req.flash('errors', errors);
    return res.redirect('/example');
  } 

  req.flash('success', { msg: 'Success!' });    
  res.redirect('/example');    
};
