OAuth2 invalid_request error.

[Ankit Kavi]

So I am trying to run the python script (oauth2.py) that google mail api offers as a tool. 

    See link: http://code.google.com/p/google-mail-oauth2-tools/wiki/OAuth2DotPyRunThrough

When I run this script and get the redirect url address I get the following error:

Error: invalid_request

Invalid parameter value for redirect_uri: Missing authority: urn:ietf: wg:oauth:2.0:oob

Request Details

• response_type=code
• scope=https://mail.google.com/
• redirect_uri=urn:ietf: wg:oauth:2.0:oob
• client_id=807325438189.apps.googleusercontent.com

Does anyone know why this would occur or have a fix for this error?

Thank you!

Are you definitely using the same uri redirect value that you set up when creating the app?

[Ankit Kavi]

Yes I am. The uri redirect is linked the the default uri generated when creating an installed app client id:

    urn:ietf:wg:oauth:2.0:oob

[David Coombes]

Generally when I set up an app the redirect is in the format http:example.com?foo=bar

Not sure where your getting that value from

That is the redirect uri i got from my API Access linked to my API Project on code.google.com after creating an installed application client id and secret.

They give two redirect uris:

urn:ietf:wg:oauth:2.0:oob http://localhost

The link in my original post has a download link for the script I am trying to use. In this script the redirect uri is set to the first of the two available uris.

Hi Ankit,

The redirect uri (urn:ietf:wg:oauth:2.0:oob) looks fine - just make sure there isn't an extra space in there. Can you please share some more information? At what step here does it fail?

I can get the script to work fine. When I go to the url that it spits out I get the error that is in my first post. I did not make any changes to the python script EXCEPT adding an import for encodings.

Essentially I cannot get past "Creating and Authorizing an OAuth Token"

[Vladimir Kolovski]

Can you please post the url that's produced by the script? FYI, I just tried running it on my machine, with your client ID, I was able to see the consent page.

wg%3Aoauth%3A2.0%3Aoob&response_type=code&scope=https%3A%2F%2Fmail.google.com%2F

[Vladimir Kolovski]

I still can't reproduce this, the URI checks out. As I implied before, you seemed to have an extra space in the redirect URI in your first post.

An extra space in the python script? I double checked that and it does not seem like I do...

[Ankit Kavi]

Oddly, when I clicked the link I sent you above I was able to get a token.

[Ankit Kavi]

And now it won't work again. This is very odd.

So now I am failing at testing IMAP and SMTP authentication. I get the following error and trace:

Traceback (most recent call last):

  File "oauth2.py", line 333, in <module>

    main(sys.argv)

  File "oauth2.py", line 320, in main

    base64_encode=False))

  File "oauth2.py", line 266, in TestImapAuthentication

    imap_conn.authenticate('XOAUTH2', lambda x: auth_string)

  File "C:\Python27\lib\imaplib.py", line 351, in authenticate

    raise self.error(dat[-1])

imaplib.error: [ALERT] Invalid credentials (Failure)

[David Coombes]

Could be wrong but I've no idea how the call back url you were using was ever going to work

That doesn't really help me solve this problem....
