Google OAuth 2 authorization - swapping code for token
Solution 1
Did you urlencode
your client secret and redirect url? That works for me.
Should be http%3A%2F%2Flocalhost
instead of https://localhost
.
Solution 2
I had the same error until I realized that I was trying to connect with a client ID which I created for iOS. So for me the solution was to create a new API key-secret pair on the API Console with the platform set to "other".
Now I'm getting other errors but that's another story. ;)
Solution 3
Happens when you use wrong Client secret. Make sure you are using correct Client secret from Google API console. I was using Email address since API console displays the information in the following order:
- Client ID
- Email address
- Client secret

I'm trying to implement Google OAuth 2 to get access to Google APIs. I follow this guide, using server-side scenario.
I have no problem with getting the code, server redirects to localhost (which is the only server allowed in redirect URIs for now). To achieve this, I go to
https://accounts.google.com/o/oauth2/auth?client_id=whatever.apps.googleusercontent.com&redirect_uri=http://localhost/&scope=https://www.google.com/m8/feeds/&response_type=code
page.Then, I tried using
curl
(as in guide) to test, if Google's server responds with access token. However, it seems to fail very hard. Only response I can get is{"error":"invalid_client"}
. I'm sure I provide everything Google wants me to provide - code, client ID, client secret, redirect URI (localhost) andgrant_type=authorization_code
.Whole
curl
command line is:curl https://accounts.google.com/o/oauth2/token -d "code=<code>&client_id=whatever.apps.googleusercontent.com&client_secret=<won't tell!>&redirect_uri=http://localhost&grant_type=authorization_code"
Am I missing something? How can I exchange code for access token?
