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

Question

I'm getting this error while trying to run my application...

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

In google API console i have registered my redirect urls

Redirect URIs:  http://localhost:8080/

And in the client_secrets.json also i'm using the same as redirect url I'm following this tutorial https://developers.google.com/bigquery/articles/dashboard#addoauth2

Edit:

I just made some changes to the existing code

Now the

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

And here is my 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

Now though its not showing any error but it displays a blank page.

Here is my 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()

So according to main.py if everything is fine it must print Hello Dashboard but it isn't

Answer 1

You will actually need to add the following to your redirect URIs:

http://localhost:8080/oauth2callback

Also, you may need to append a trailing / if the above doesn't match:

http://localhost:8080/oauth2callback/

Answer 2

using google openId I configured this

Redirect URIs: http://domain.com/authenticate/google

on https://code.google.com/apis/console, if you must create a app if you don't have one, note that must match entirely the url

Answer 3

In main.py functions main class add (decorator.callback_path, decorator.callback_handler()), and remove

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

from app.yaml.

PS: You might get DownloadError if you have some proxy-configuration/webcontent-filter. If you disable these configurations or deploy it on Google Server, it will work just fine.
