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

Solution 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/

Solution 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

Solution 3

seems like google tries to match url with being case-sensitve cause when i tried it with /Authorize and /authorize, it gave me redirect_uri_mismatch error for first one but worked for latter one

someone try and let me know if i m wrong

Solution 4

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.

@jade And just to be sure, you set this up as a Web Application in the console, correct?

[RocketDonkey]

@jade For right now you are following the tutorial step-by-step?

[RocketDonkey]

@jade Looking at the question you just asked (about app.yaml), did you have it properly configured?

[iJade]

i have updated my question as u said.Now the error is not showing up but i'm not getting the expected output.And when i tried with the trailing / thing as localhost:8080/oauth2callback it shows the same error

[RocketDonkey]

@jade This shouldn't make a difference, but I've usually specified the 'final' handler as - url: /.* (instead of - url: .*). When you see the blank page, what is the URL?

[Leo]

The path part of web URLs is case sensitive so that seems correct.

It's also worth noting that when you update the dev console, it can take about 20 minutes to catch up. I had everything right, and couldn't figure out why I was still getting this error.

Wow. The trailing slash was indeed a problem. Thanks Google! It's bad enough that you can't provide a proper JavaScript library (with an NPM package), but you'll also be very pedantic about a trailing slash.
