HttpError：<HttpError 400 请求 https://www.googleapis.com/bigquery/v2/projects/ 时

Question

这是我在尝试对 bigquery 进行身份验证调用时遇到的错误数据

HttpError: <HttpError 400 when requesting https://www.googleapis.com/bigquery/v2/projects/ClientId/datasets/samples/tables/natality?alt=json returned "Invalid project ID 'ClientId'. Project IDs must contain 6-63 lowercase letters, digits, or dashes. IDs must start with a letter and may not end with a dash.">

这是我的 main.py

import httplib2
import os
from google.appengine.api import memcache
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from oauth2client.appengine import oauth2decorator_from_clientsecrets
from bqclient import BigQueryClient


PROJECT_ID = "########"  this is the Client Id 
DATASET = "samples"
TABLE = "natality"


CLIENT_SECRETS = os.path.join(os.path.dirname(__file__),
    'client_secrets.json')

http = httplib2.Http(memcache)
decorator = oauth2decorator_from_clientsecrets(CLIENT_SECRETS,
    'https://www.googleapis.com/auth/bigquery')

bq = BigQueryClient(http, decorator)

class MainHandler(webapp.RequestHandler):
    @decorator.oauth_required
    def get(self):
        self.response.out.write("Hello Dashboard!\n")
        modTime = bq.getLastModTime(PROJECT_ID, DATASET, TABLE)
        if modTime is not None:
            msg = 'Last mod time = ' + modTime
        else:
            msg = "Could not find last modification time.\n"
        self.response.out.write(msg)

application = webapp.WSGIApplication([
   ('/', MainHandler),
   (decorator.callback_path, decorator.callback_handler())
], debug=True)

def main():
   run_wsgi_app(application)

if __name__ == '__main__':
    main()

这里是 app.yaml

application: hellomydashboard
version: 1
runtime: python
api_version: 1

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.py

这里是 bqclient.py

import httplib2
from apiclient.discovery import build
from oauth2client.appengine import oauth2decorator_from_clientsecrets

class BigQueryClient(object):
    def __init__(self, http, decorator):
        """Creates the BigQuery client connection"""
        self.service = build('bigquery', 'v2', http=http)
        self.decorator = decorator

    def getTableData(self, project, dataset, table):
        decorated = self.decorator.http()
        return self.service.tables().get(projectId=project, datasetId=dataset,
            tableId=table).execute(decorated)

    def getLastModTime(self, project, dataset, table):
        data = self.getTableData(project, dataset, table)
        if data is not None and 'lastModifiedTime' in data:
            return data['lastModifiedTime']
        else:
            return None

    def Query(self, query, project, timeout_ms=10000):
        query_config = {
            'query': query,
            'timeoutMs': timeout_ms
        }
        decorated = self.decorator.http()
        result_json = (self.service.jobs()
                       .query(projectId=project, body=query_config)
                       .execute(decorated))

        return result_json

我也尝试用错误中所述的项目 ID 替换 ClientId，但它给出了另一个错误

HttpError: <HttpError 404 when requesting https://www.googleapis.com/bigquery/v2/projects/hellodashboard87/datasets/samples/tables/natality?alt=json returned "Not Found: Dataset hellodashboard87:samples">

Answer 1

要使用 Google 的 BigQuery 提供的公共数据集，请使用以下参数：

项目 ID：publicdata

数据集 ID：samples

表 ID：natality（或任何你想使用的）

要使用您拥有的任何数据集，请将您的项目 ID 切换到 API 控制台仪表板中的 ID。

Answer 2

为了使用 BigQuery，您必须在 APIs Console 中创建一个启用 BigQuery 的项目（我假设您已经这样做了）。创建项目后，您将能够从 URL 中获取 项目编号，例如

https://code.google.com/apis/console/#project:12345XXXXXXX

在示例中，项目编号为 12345XXXXXXX，这是您将用于 PROJECT_ID 的值。
