授权 Cloud SQL Admin API 从 Cloud Function 调用

Question

我正在尝试构建小函数（后来部署到云函数）以将 BAK 文件恢复到云 sql。此功能将由 cron 触发。在阅读有关授权此 API 的文档时，我有点迷路：https://cloud.google.com/sql/docs/sqlserver/import-export/importing#importing_data_from_a_bak_file_in

已创建包含此角色的服务帐户：Cloud SQL Admin、Storage Admin、Storage Object Admin、Storage Object Viewer，并在创建 Cloud Function 时从下拉列表中选择该服务帐户，但不起作用。

阅读此文后还尝试生成 API 密钥：https://cloud.google.com/sql/docs/sqlserver/admin-api/how-tos/authorizing

所以我的POSTurl变成了这个：

https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id/import?key=generatedAPIKey

但仍然出现错误：

  "error": {
    "code": 401,
    "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "errors": [
      {
        "message": "Login Required.",
        "domain": "global",
        "reason": "required",
        "location": "Authorization",
        "locationType": "header"
      }
    ],
    "status": "UNAUTHENTICATED"
  }
}

我需要为此使用 Oauth 2 吗？这是我在 Cloud Function 中的代码：

import http.client
import mimetypes

def restore_bak(request):
    conn = http.client.HTTPSConnection("www.googleapis.com")
    payload = "{\r\n \"importContext\":\r\n   {\r\n      \"fileType\": \"BAK\",\r\n      \"uri\": \"gs://{bucket_name}/{backup_name}.bak\",\r\n      \"database\": \"{database_name}\"\r\n    }\r\n}\r\n"
    headers = {
      'Content-Type': 'application/json'
    }
    conn.request("POST", "/sql/v1beta4/projects/{project_id}/instances/{instance_name}/import", payload, headers)
    res = conn.getresponse()
    data = res.read()
    print(data.decode("utf-8"))
    return(data.decode("utf-8"))

这看起来像 python，所以我建议使用 Discovery Client Library for Python。这个库围绕 SQL Admin API:

提供了一个方便的包装器

# Construct the service object for the interacting with the Cloud SQL Admin API.
service = discovery.build('sqladmin', 'v1beta4', http=http)

req = service.instances().list(project="PROJECT_ID")
resp = req.execute()
print json.dumps(resp, indent=2)

默认情况下，此库使用“Application Default Credentials (ADC)”策略从环境中获取您的凭据。

您还可以通过创建 oauth2 令牌并将其设置为请求中的 header 来手动验证您的请求（例如，如果您想使用 asyncio）。最简单的方法是使用 google-auth 包获取 ADC 并将其设置为 header:

import google.auth
import google.auth.transport.requests

credentials, project_id = google.auth.default()
credentials.refresh(google.auth.transport.requests.Request())
headers = {
    "Authorization": "Bearer {}".format(credentials.token),
    "Content-Type": "application/json"
}
