UnhandledPromiseRejectionWarning:错误:错误:0906D06C:PEM例程:PEM_read_bio:无起始行

标签: node.js reactjs firebase express

我有一个带有节点/表达服务器,React客户端和Firebase Firestore作为数据库的应用程序。当我在firebase数据库上执行操作时,我的代码似乎可以正常工作,但是数据没有显示在firestore控制台中,并且出现以下错误。

我实现了以下解决方案,但是它不起作用: https://stackoverflow.com/a/40321130/1438277

我正在运行npm 6.9.0和节点v11.8.0

谢谢

这是我从快递服务器发出的数据库调用:

const admin = require('firebase-admin')
const config = require('./config.js')

exports.createAsin = p => {
  try {
    let addDoc = config.db.collection('asins').add({
      uid: p.uid,
      asin: p.asin,
      mapPrice: p.mapPrice,
      data: []
    })
    console.log('db: ASIN created')
    return p
  } catch (e) {
    console.log('db: error creating ASIN /', e)
    return null
  }
}

Firebase(或任何数据库)调用是异步事件,因此您需要使用Promise或回调函数来避免Promise拒绝错误。这是Javascript Promise的文档: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

这是有关如何将它们与Firebase一起使用的非常有用的文章: https://howtofirebase.com/promises-for-firebase-bbb9d0d595ed

例如,您可以做类似

的操作
exports.createAsin = async p => {
  try {
    let addDoc = await config.db.collection('asins').add({
      ...
    })
    console.log('db: ASIN created')
    return p
  } catch (e) {
    ...
  }
}

我终于弄明白了:我将Firebase的json认证文件放在.env文件中,这就是造成此错误的原因。我将其移到一个单独的json文件中(并将其添加到.gitignore中),它可以正常工作。 phe!
