I was doing my development with Google Drive API using [localhost:8080]. Suddenly I felt to test it in my local deployment sandbox and it has IP address as [192.168.1.1:8080]. And as per that I changed the credential in developer console client callback URL. I am using OAuth2WebServerFlow to get the refresh token using user consent. Then in future I am using the refresh token and OAuth2WebServerFlow to authenticate the user. But I was surprised - I got the error:
I don't know what is happening or how can I fix it. What is going on, I don't understand
An alternative to editing a hosts
file is to use the "Magic DNS" service http://xip.io/ or http://nip.io/ (see edit)
xip.io is a magic domain name that provides wildcard DNS for any IP address.Say your LAN IP address is 10.0.0.1. Using xip.io,
10.0.0.1.xip.io resolves to 10.0.0.1 www.10.0.0.1.xip.io resolves to 10.0.0.1 mysite.10.0.0.1.xip.io resolves to 10.0.0.1 foo.bar.10.0.0.1.xip.io resolves to 10.0.0.1
With this service, you can specify a public-looking domain that resolves to a private address.
In the Console, if your Redirect URI was (what you wish you had anyways):
http://192.168.1.1:8080/auth/google_oath2/callback
Replace it with:
http://192.168.1.1.xip.io:8080/auth/google_oath2/callback
"Redirect URIs" does not seem to accept wildcards, so the entire private ip-xip.io needs to be specified in the console.
I have no affiliation with xip.io; I'm just a satisfied user.
2016 Edit: I've heard reports of instability with the xip.io DNS servers. There is a copy-cat service nip.io that behaves exactly the same as xip.io, but during July 2016, nip.io had a 100% response rate while xip.io did not.
Google will not accept a local (private) IP address when doing Oauth calls. My workaround was to add an entry in my Windows hosts file for the local IP:
\Windows\System32\drivers\etc
192.168.1.2 fakedomain.com
then register fakedomain.com
with Google in their dev console. That appears as a "real" domain to them, but will still resolve in your browser to the local IP. I'm sure a similar approach on Mac or Linux would also work.
Edit: Only relevant when developing locally.
Ok, I'm having the same problem on my Mac. Following steps resolved the issue
Go to your google development console https://console.developers.google.com/project, choose credentials and change the callback IP to a domain like http://myflask.com:5000/oauth2callback. In my case I am using a Flask application, so the 5000 port is necessary.
Next add to your private/etc/hosts
file a new entry matching the above hostname to your IP, like so:
# (example IP)
172.1.1.1 myflask.com
Give Google a minute to update your credentials, and visit your site at http://myflask.com:5000
I got the same error until I changed it from an IP address to a domain name, (192.168.1.113 to localhost in my case) so it looks like Google won't accept bare IP addresses.
Use a domain name for your sandbox, or setup a local domain server if you don't have one.
