oauth2.py stopped to work - urllib.py, httplib.py and socket.py issues

[marcelolaia]

Hi,

I use this approach to send my emails by msmtp. However, oauth2.py stopped to work 08-15-2020.

Traceback (most recent call last):
  File "/home/myuser/bin/OAuth2/oauth2.py", line 347, in <module>
    main(sys.argv)
  File "/home/myuser/bin/OAuth2/oauth2.py", line 307, in main

    return getattr(self, name)(url, data)
  File "/usr/lib/python2.7/urllib.py", line 445, in open_https

    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
IOError: [Errno socket error] [Errno -2] Name or service not known

I made a test and run:

$ ./oauth2.py --user=myuser@domain.edu.br --client_id=9876........apps.googleusercontent.com --client_secret=***************************************** --generate_oauth2_token

To authorize token, visit this url and follow the directions:
  https://accounts.google.com/o/oauth2/auth?client_id=4485...........apps.googleusercontent.com&redirect_uri=*********************************mail.google.com%2F

I followed that link and made authorization. So, I got the verification code and enter it on the prompt Enter verification code:

After that, I got the same error messages as above:

Traceback (most recent call last):
  File "./oauth2.py", line 366, in <module>
    main(sys.argv)

myuser@myuser:~/bin/OAuth2$ 

I have applied the patch for python 3.0 and 2.7 compatibility (here).

Any thoughts?

Thank you

[marcelolaia]

offlineimap work very nice without any issues.

@marcelolaia Could you please share the offlineimap change details ? I am also stuck in the above issue you have mentioned here.

Hi @shiben-lab, I'm so sorry for delay in replay.
I have been set up my .offlineimaprc like the instructions here.
The relevant part is:

[Repository ExampleCompanyRemote]
type = IMAP
remotehost = imap.gmail.com
remoteuser = myuser
ssl = yes
starttls = no
sslcacertfile = /etc/ssl/certs/ca-certificates.crt
auth_mechanisms = XOAUTH2
oauth2_client_id = YOUR_CLIENT_ID_HERE
oauth2_client_secret = YOUR_CLIENT_SECRET_HERE
oauth2_request_url = https://accounts.google.com/o/oauth2/token
oauth2_refresh_token = YOUR_REFRESH_TOKEN_HERE

Please, tell me if you have solved your issue.

My msmtp issue continue unsolved.

I tried it with python 3.8 and it not run:

During handling of the above exception, another exception occurred:

Hey @marcelolaia,

If you are still stuck, you can try this minimal script I wrote for myself: gmail-oauth2_none_none.sh

It just requires bash, curl and jq on your system.

[marcelolaia]

Hi @MunifTanjim, thank you so much! Please, could you share the needed configurations to do? You use it with msmtp?

[MunifTanjim]

You use it with msmtp?

Yes.

You can put this in your msmtp config:

auth oauthbearer
passwordeval "gmail-oauth2.sh access_token --client-id CLIENT_ID --client-secret CLIENT_SECRET --refresh_token REFRESH_TOKEN"

You can get the REFRESH_TOKEN by running this:

gmail-oauth2.sh refresh_token --client-id CLIENT_ID --client-secret CLIENT_SECRET

---

If you don't want to put these sensitive CLIENT_SECRET or REFRESH_TOKEN in your config file you can take a look at another script that I actually use: gmail-oauth2_bitwarden_secret-tool.sh

It needs Bitwarden CLI bw and secret-tool. With it, I just put these in my configs:

# msmtp
auth oauthbearer
passwordeval "gmail-oauth2.sh access_token me@example.com"

# mbsync
AuthMechs XOAUTH2
PassCmd "gmail-oauth2.sh access_token me@exmaple.com"
