Firebase云功能触发FCM,但请求缺少必需的身份验证凭据

我正在尝试在firebase云功能中使用firebase-admin通过Firebase云消息传递(FCM)发送消息。

在阅读documentation时会说

  

要使用Admin FCM API,必须首先按照将Firebase Admin SDK添加到服务器中的步骤进行操作。

但是我认为这不是必需的,因为我仅使用云功能吗?

无论如何,这一切都会一直进行到admin.messaging().send,直到出现此错误为止:

Error sending message: { Error: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.

     message: 'Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.' },
  codePrefix: 'messaging' }

这是我的云函数源代码

import * as functions from 'firebase-functions'
import * as admin from 'firebase-admin'

admin.initializeApp(functions.config().firebase)
const firestore = admin.firestore()
firestore.settings({timestampsInSnapshots: true})

exports.notification = functions.firestore
  .document(path)
  .onUpdate(async (change, context) => {
    const deviceTokens = ['deviceToken-123123123']
    deviceTokens.forEach(token => {
      const fcmMessage = {
        notification: {title: 'test title', body: 'test body'},
        token
      }
      admin.messaging().send(fcmMessage)
        .then((response) => {
          // Response is a message ID string.
          console.log('Successfully sent message:', response)
        })
        .catch((error) => {
          console.log('Error sending message:', error)
        })
    })
  })

设备令牌存储在Firestore中,并且也可以从该Cloud函数内部的Firestore中检索。设备令牌的格式正确。在此示例中,我已将其替换为占位符。

我也到处寻找类似的问题,但我唯一能找到的是this one

答案 0 :(得分:0)

经过大量搜索后,我发现了一个error list by firebase,并在此列表中跟踪了错误代码'messaging/invalid-apns-credentials',其中说:

  

无法发送针对iOS设备的消息,因为所需的APNs SSL证书未上传或已过期。检查您的开发和生产证书的有效性。

所以我想,我还没有设置我的“生产”证书,也许我的cordova开发版本已被视为生产版本!因此,我只是继续添加了生产证书,还确定要删除并重新添加dev证书,并且它可以正常工作。
