Question

我正在运行数据存储模拟器。当我运行“ dev_appserver.py app.yaml”命令时，出现此错误

403权限不足或不足。

这是我得到的警告。我知道身份验证有问题。我经历了this。但是最终找不到解决方法。

一些细节：

我正在为某些应用程序使用MySQL数据库。
对于其他人，我想使用数据存储。
我在一个选项卡上运行数据存储模拟器，在另一个选项卡上运行Google云代理，在第三个选项卡上运行dev_appserver。
我已经使用命令gcloud beta emulators数据存储区env-init设置了环境变量。

我的settings.py

if os.getenv('GAE_APPLICATION', None):
# Running on production App Engine, so connect to Google Cloud SQL using
# the unix socket at /cloudsql/<your-cloudsql-connection string>
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'HOST': '/cloudsql/connectionname',
        'NAME': 'db_name',
        'USER': 'username',
        'PASSWORD': 'password',
    }
}
else:
# Running locally so connect to either a local MySQL instance or connect to
# Cloud SQL via the proxy. To start the proxy via command line:
#
#     $ cloud_sql_proxy -instances=[INSTANCE_CONNECTION_NAME]=tcp:3306
#
# See https://cloud.google.com/sql/docs/mysql-connect-proxy
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'HOST': '127.0.0.1',
        'PORT': '3307',
        'NAME': 'dbname',
        'USER': 'username',
        'PASSWORD': 'password',
    }
}    
# [END db_setup]

您的默认服务帐户似乎没有足够的权限。可能需要一些其他权限，例如“ Datastore Index Admin”才能推断出Datastore [1]。我不确定这在Datastore仿真器中如何工作，但是由于它旨在提供本地仿真，因此也许它将获得执行测试的角色和权限。您能否检查您的服务帐户中的权限[2]，是否需要进行更改，如果问题仍然存在，请通知我。我将等待您的答复。
