出现错误：redirect_uri_mismatch请求中的重定向URI：http：// localhost：8080 / oauth2callback与注册的重定向URI不匹配

问题描述

实际上，您将需要在重定向URI中添加以下内容：

http://localhost:8080/oauth2callback

另外，/如果以上条件不匹配，则可能需要附加尾随：

http://localhost:8080/oauth2callback/

解决方法

尝试运行我的应用程序时出现此错误…

The redirect URI in the request: http://localhost:8080/oauth2callback did not match a registered redirect URI

在Google API控制台中，我已经注册了重定向网址

Redirect URIs:  http://localhost:8080/

而且在client_secrets.json中，我也使用与重定向URL相同的名称，我在遵循本教程
 https://developers.google.com/bigquery/articles/dashboard#addoauth2

编辑：

我刚刚对现有代码进行了一些更改

现在

redirect URIs in API console is     http://localhost:8080/oauth2callback

这是我的app.yaml

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

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

- url: /oauth2callback
  script: oauth2client/appengine.py

- url: .*
  script: main.py

现在，尽管它没有显示任何错误，但是显示了一个空白页。

这是我的main.py

from bqclient import BigQueryClient
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

# Project ID for project to receive bill.
# During limited availability preview,there is no bill.
# The value should be your quoted Client ID number 
# which you previously recorded from code.google.com/apis/console

# REPLACE THIS NUMBER WITH YOUR CLIENT ID
PROJECT_ID = "My Project ID"  #i just replaced dat
DATASET = "samples"
TABLE = "natality"

# CLIENT_SECRETS,name of a file containing the OAuth 2.0
# information for this application.
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")


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

def main():
   run_wsgi_app(application)

if __name__ == '__main__':
    main()

因此，根据main.py，如果一切正常，则必须打印Hello Dashboard，但事实并非如此
