gcloud.exceptions.Forbidden:403权限丢失或不足

Question

我是谷歌云平台的新手。我已经设置了一个Google VM实例。运行命令时，我在本地计算机上遇到身份验证问题：

python manage.py makemigrations

你能提出一些解决问题的建议吗？

gcloud.exceptions.Forbidden: 403 Missing or insufficient permissions.

其他信息：

gcloud auth list
Credentialed Accounts:
 - user_account@gmail.com ACTIVE
To set the active account, run:
    $ gcloud config set account `ACCOUNT`

gcloud config list
Your active configuration is: [default]

[core]
account = user_account@gmail.com
disable_usage_reporting = True
project = user_project

输入：（独立的Python函数）

from gcloud import datastore
client = datastore.Client('user_project')

print(vars(client.connection.credentials))

输出：

{'scopes': set([]), 'revoke_uri': 'https://accounts.google.com/o/oauth2/revoke', 'access_token': None, 'token_uri': 'https://www.googleapis.com/oauth2/v4/token', 'token_info_uri': None, 'token_response': None, 'invalid': False, 'refresh_token': u'1/t-V_pZicXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 'client_id': u'3XXXXXXXX9.apps.googleusercontent.com', 'id_token': None, 'client_secret': u'ZXXXXXXXXXXXXXXXXXXX2', 'token_expiry': None, 'store': None, 'user_agent': 'Python client library'}

Answer 1

只需运行以下两个命令：

 1. gcloud beta auth application-default login
 2. export GOOGLE_APPLICATION_CREDENTIALS='/<path_to_json>/client_secrets.json'

从本地机器开始工作。

Answer 2

应用程序默认凭据的行为自128版起在gcloud中有changed。

一个人应该使用

gcloud auth application-default login

相反。

请注意，通过gcloud auth login或gcloud init或gcloud config set account MY_ACCOUNT更改凭据不会影响应用程序默认凭据，它们与gcloud凭据分开管理。

Answer 3

使用本地开发中的数据存储模拟器，我必须基于Datastore and DatastoreClient docs设置apiEndpoint。对此可能有更优雅的处理，但这解决了本地开发中的代码7“权限丢失或不足”错误。（我在数据存储模式下使用Firestore。）

// nodejs myapp.js excerpt for config change running locally
    if(process.env.DATASTORE_EMULATOR_HOST){
        serviceaccount.apiEndpoint = process.env.DATASTORE_EMULATOR_HOST;
    }
    const datastore = new Datastore(serviceaccount);

$ gcloud beta emulators datastore start --data-dir=./emulator-data/
    ....
    [datastore] API endpoint: http://localhost:8081
    [datastore] If you are using a library that supports the DATASTORE_EMULATOR_HOST environment variable, run:
    [datastore]
    [datastore]   export DATASTORE_EMULATOR_HOST=localhost:8081
    [datastore]
    [datastore] Dev App Server is now running.

$ export DATASTORE_EMULATOR_HOST=localhost:8081 && MYHOST='http://localhost:8111' ndb node myapp.js
