具有真实数据库的Firestore本地http:Cloud Firestore模拟器未运行，因此数据库操作将失败，并显示“默认凭据"错误 [英] Firestore local http with real db: The Cloud Firestore emulator is not running so database operations will fail with a 'default credentials' error
问题描述
我想在本地运行一个firebase http云功能，以访问一个真正的远程firestore数据库.
I want to run a firebase http cloud function locally accessing a real remote firestore database.
为此，我正在使用以下命令在本地运行函数:
To do it, I'm running my functions locally using:
FIREBASE_CONFIG="/path-to-credential.json" GOOGLE_APPLICATION_CREDENTIALS="/path-to-credential.json" firebase emulators:start --only functions
如此处 https://firebase.google.com/docs/admin/setup ，这应允许在不使用任何参数的情况下初始化admin sdk.我的功能index.js如下
As written here https://firebase.google.com/docs/admin/setup, this should permit the initialization of the admin sdk without any parameter. My functions index.js is as following
import * as admin from 'firebase-admin';
import * as fromHttpFunc from './http/func';
admin.initializeApp();
export const httpFunc = fromHttpFunc.httpFunc;
然后我在浏览器中调用该函数时，这就是我在日志中得到的信息
When I then call the function in the browser, this is what I get in logs

我没有发现什么问题，我还通过执行cat /path-to-credential.json检查了证书的路径是否正确，并且我有一个带有client_email字段的json.
I don't get what's wrong, I also checked if the path to the credential is ok by doing cat /path-to-credential.json and I have a json with the client_email field.
推荐答案
通过确保以下各项，使本地云功能可与真正的远程数据库一起使用:
Managed to have the local cloud functions working with the real remote DB by making sure of the following:
-
运行
firebase login并登录到要使用的项目
run
firebase loginand login into the project you want to use
关注此评论 https://github.com/firebase/firebase-functions/issues/121#issuecomment-337065268 以确保文件不存在(我出现了invalid_grant错误)
follow this comment https://github.com/firebase/firebase-functions/issues/121#issuecomment-337065268 to make sure the file is not there (I had a invalid_grant error)
运行export GOOGLE_APPLICATION_CREDENTIALS="SERVICE_ACCOUNT_PATH.json"(替换SERVICE_ACCOUNT_PATH)
run export GOOGLE_APPLICATION_CREDENTIALS="SERVICE_ACCOUNT_PATH.json" in the terminal session you want to use (replace SERVICE_ACCOUNT_PATH)
不是通过使用firebase emulators:start --only functions而是通过使用firebase serve --only functions来服务您的http函数.当前，这是未记录的行为: https://github.com/firebase/firebase-tools/issues/1412#issuecomment-504561828 .
serve your http functions NOT by using firebase emulators:start --only functions but using firebase serve --only functions. Currently, this is an undocumented behaviour: https://github.com/firebase/firebase-tools/issues/1412#issuecomment-504561828.
按如下所示初始化应用程序(更新YOUR_APP_ID):
initialize the app as following (update YOUR_APP_ID):
admin.initializeApp({
credential: admin.credential.applicationDefault()
});
admin.initializeApp({
credential: admin.credential.applicationDefault()
});
