一切似乎都好,它允许我做的一切教程,但当我运行的功能,我得到这个错误。

gcloud firestore导出gs://bbbdata备份

我正在使用firebase站点上的GCP控制台并使用此代码。

const firestore = require('@google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();

const bucket = 'gs://bbbdata-backup'

exports.scheduledFirestoreExport = (event, context) => {
const databaseName = client.databasePath(
process.env.GCLOUD_PROJECT,
'(default)'
);

return client
 .exportDocuments({
  name: databaseName,
  outputUriPrefix: bucket,
  // Leave collectionIds empty to export all collections
  // or define a list of collection IDs:
  // collectionIds: ['users', 'posts']
  collectionIds: [],
})
.then(responses => {
  const response = responses[0];
  console.log(`Operation Name: ${response['name']}`);
  return response;
})
.catch(err => {
  console.error(err);
});
};

我去年也遇到过类似的问题,可能你错过了一些许可,我会这样做,希望这对你有用:

import * as functions from 'firebase-functions'
import { auth } from 'google-auth-library'

export const generateBackup = async () => {
  const client = await auth.getClient({
    scopes: [
      'https://www.googleapis.com/auth/datastore',
      'https://www.googleapis.com/auth/cloud-platform'
    ]
  })

  const path = `YOUR_FOLDER_NAME_FOR_THE_BACKUP`
  const BUCKET_NAME = `YOUR_BUCKET_NAME_HERE`

  const projectId = await auth.getProjectId()
  const url = `https://firestore.googleapis.com/v1beta1/projects/${projectId}/databases/(default):exportDocuments`
  const backup_route = `gs://${BUCKET_NAME}/${path}`

  return client.request({
    url,
    method: 'POST',
    data: {
        outputUriPrefix: backup_route,
        // collectionsIds: [] // if you want to specify which collections to export, none means all
    }
  })
  .catch(async (e) => {
    return Promise.reject({ message: e.message })
  })

}

然后,您可以决定这是这个函数的触发器,并相应地执行它。

注意:转到项目的IAM部分并找到appengine服务帐户,您将需要添加角色 Cloud Datastore Import Export Admin ,否则将失败。

你可以多看看 here 非常详细。
