Question

我正在学习本教程

https://developers.google.com/bigquery/docs/authorization#service-accounts-appengine

这是我的main.py代码

import httplib2

from apiclient.discovery import build
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
from oauth2client.appengine import AppAssertionCredentials

# BigQuery API Settings
SCOPE = 'https://www.googleapis.com/auth/bigquery'
PROJECT_NUMBER = 'XXXXXXXXXX' # REPLACE WITH YOUR Project ID

# Create a new API service for interacting with BigQuery
credentials = AppAssertionCredentials(scope=SCOPE)
http = credentials.authorize(httplib2.Http())
bigquery_service = build('bigquery', 'v2', http=http)


class ListDatasets(webapp.RequestHandler):
  def get(self):
    datasets = bigquery_service.datasets()
    listReply = datasets.list(projectId=PROJECT_NUMBER).execute()
    self.response.out.write('Dataset list:')
    self.response.out.write(listReply)


application = webapp.WSGIApplication(
                                     [('/listdatasets(.*)', ListDatasets)],
                                     debug=True)

def main():
  run_wsgi_app(application)

if __name__ == "__main__":
  main()

这是我的app.yaml文件代码

application: bigquerymashup
version: 1
runtime: python
api_version: 1

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

- url: .*
  script: main.py

是的，我已经在谷歌api控制台的“团队”选项卡中添加了应用引擎服务帐户名称，可以编辑权限。上传应用程序并尝试访问链接时显示

Oops! This link appears to be broken.

Ealier我在本地运行并试图使用链接localhost:8080访问它。然后我认为可能在本地运行可能会出错，所以我上传了我的代码

http://bigquerymashup.appspot.com/

但仍然给出错误。

修改更新了App.yaml

application: bigquerymashup
version: 1
runtime: python
api_version: 1

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

- url: .*
  script: main.py

- url: /listdatasets
  script: main.py

但是又出现了另一个错误

Traceback (most recent call last): File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/_webapp2‌5.py", line 710, in call handler.get(*groups) TypeError: get() takes exactly 1 argument (2 given)

Answer 1

您需要定义与您尝试查找的网址匹配的脚本处理程序。

尝试：http://[your_app_id_here].appspot.com/listdatasets
