这是我第一个使用django在Google Cloud Console上发布的项目，但它给出了错误：无法连接到服务器：连接被拒绝 服务器是否在主机“ 127.0.0.1”上运行并接受 端口5432上的TCP / IP连接？ 加载其他页面，但是当我想连接到psql db时，这是在将debug设置为True后得到的错误消息。以下是我的数据库设置和pg_hba.conf文件。我必须在这里错过一些重要的东西。
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'HOST': '/cloudsql/appname:europe-west1:instance name',
'USER': '',
'PASSWORD': '',

}
}
else:

'HOST': '127.0.0.1',
'PORT': '5432',
'NAME': '',
'USER': '',

}
}

这是在db设置中删除if else之后的新异常

答案 0 :(得分：0)
在查看您发布的跟踪信息后，我注意到了这一点：
Exception Type: OperationalError at /admin/login/
Exception Value: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/cloudsql/bs:europe-west1:bs-dev/.s.PGSQL.5432"?
您用于连接到Cloud SQL的格式是这种格式。
ProjectID：zone：instance
您确定要传递的项目ID是正确的吗？您的项目ID是“ bs”吗？
