我正在尝试为Firestore创建备份系统。
我遵循此guide的每一步,当我尝试部署代码时,它返回Request failed with status code 400
PROJECT-ID@appspot.gserviceaccount.com权限:Cloud Datastore导入导出管理员, 编辑, 存储管理员
这是app.js的代码
'use strict';
const axios = require('axios');
const dateformat = require('dateformat');
const { google } = require('googleapis');
const express = require('express');
const util = require('util')
const request = require('request');
const admin = require('firebase-admin');
const {Storage} = require('@google-cloud/storage');
// Creates a client
const storage = new Storage();
admin.initializeApp({
credential: admin.credential.applicationDefault()
});
const db = admin.firestore();
const googleMapsClient = require('@google/maps').createClient({
key: 'AIza*****',
Promise: Promise
});
const app = express();
// Trigger a backup
app.get('/cloud-firestore-export', async (req, res) => {
const auth = await google.auth.getClient({
scopes: ['https://www.googleapis.com/auth/datastore'],
});
const accessTokenResponse = await auth.getAccessToken();
const accessToken = accessTokenResponse.token;
const headers = {
'Content-Type': 'application/json',
Authorization: 'Bearer ' + accessToken,
};
const { outputUriPrefix } = req.query;
if (!outputUriPrefix) {
res.status(500).send('outputUriPrefix required');
} else if (outputUriPrefix && outputUriPrefix.indexOf('gs://') !== 0) {
res.status(500).send('Malformed outputUriPrefix: ${outputUriPrefix}');
}
// Construct a backup path folder based on the timestamp
const timestamp = dateformat(Date.now(), 'yyyy-mm-dd-HH-MM-ss');
let path = outputUriPrefix;
if (path.endsWith('/')) {
path += timestamp;
} else {
path += '/' + timestamp;
}
const body = {
outputUriPrefix: path,
};
// If specified, mark specific collections for backup
const { collections } = req.query;
if (collections) {
body.collectionIds = collections.split(',');
}
const projectId = process.env.GOOGLE_CLOUD_PROJECT;
const url = 'https://firestore.googleapis.com/v1beta1/projects/' + projectId + '/databases/(default):exportDocuments';
try {
const response = await axios.post(url, body, { headers });
res
.status(200)
.send(response.data)
.end();
} catch (e) {
if (e.response) {
console.warn(e.response.data);
}
res
.status(500)
.send('Could not start backup:' + e.message)
.end();
}
});

// Start the server
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
console.log('App listening on port ${PORT}');
console.log('Press Ctrl+C to quit.');
});
我还有另一个正在监听“ /”的功能。可能会导致此问题吗?

我还查看了Cron日志,与该错误没有任何关系。它仅返回500 error

因此,我一直在复制您的问题,并找到了解决方案。
我一直遇到与您相同的错误,最终我设法弄清楚了。如果查看GAE日志,则会看到错误消息,指出“项目\”“您的项目” \'不是已启用Cloud Firestore的项目。”。
这对我有用:
如果您在实际项目中启用了DataStore,则在第3步将无法执行Firestore实例。
这将为您创建您拥有权限的.appspot.com格式的所需存储桶。
转到GAE并创建您的cron.yaml,app.js以及您需要的其他所有内容。我使用this repo进行测试。
在存储库的readme.md中,您具有为授予服务帐户权限所必须执行的确切命令。
请记住按照cron.yaml中的说明更改存储桶。
按照回购协议中提到的步骤进行,因为它们已经做得很好。
让我知道它是否对您有用!

主要问题是铲斗位置
创建备份存储桶时,您必须使用Multi-Region
,否则您将收到来自服务器的拒绝。
我认为这是Google Cloud的错误
解决方案
删除存储桶并创建一个具有多区域位置的新存储桶
单一位置的错误:
'Bucket backup-bucket is in location EUR4. This project can only operate on buckets
spanning location europe-north1 or europe-west1 or eu or europe-west2 or
europe-west3 or europe-west4 or europe-west5 or europe-west6.',
