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
如错误中所述，我还尝试将 ClientId 替换为项目 ID，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">
