Connect with Google Contacts

[xet7]

Moved to here from phildini#36

From @phildini

https://developers.google.com/google-apps/contacts/v3/?hl=en

http://django-allauth.readthedocs.org/en/latest/providers.html#google

https://developers.google.com/identity/protocols/googlescopes

https://developers.google.com/google-apps/carddav/?hl=en_US

So, digging into this, here are my findings so far:

• the gdata library that I could use to access the contacts API doesn't support python 3
• pyCardDav, the only python client library I could find for the CardDav API, also doesn't support python 3
• django allauth doesn't have the correct scoping to get a good api key for accessing the contacts api over OAuth.

In other words, I'm going to have to science the crap out of this.

science in the github-esque dat-science meaning?​

From @phildini

Lol, I'm actually referencing a line from the movie "The Martian".

What I think I'll really need to do is:

• Write my own oauth integration
• Write my own contacts api client library and/or carddav api client library

From @paulproteus

Or have a weekend sprint with me where we python-3-ify those libraries!

"how hard could it be"?

From @phildini

Here's one of them:
https://github.com/google/gdata-python-client

Here's the other one:
https://github.com/geier/pycarddav

I don't know if it's worth it to try to update them over re-writing them. pycarddav in particular is based on the vobject library, which is massive, hasn't been updated since like '09, and also doesn't support python3.

From @paulproteus

gdata-python-client has some activity where people want Python 3 at least,
so we'd be serving the community:
google/gdata-python-client#29

From @phildini

I'm also not sure that syncing over that API is the best approach. It would require doing "since time changed" queries, then comparing against what's in ContactOtter... which I guess is basically what CardDav is already doing? 😝

@paulproteus if you're interested in doing a hacking session this weekend to help me nail this out (and maybe work a bit more on phildini#8) I'd be more interested. If I'm doing this on my own, I'll probably write a client that does just what I need.

The saga continues.

Dug more into the contacts API, found that it linked to https://developers.google.com/api-client-library/python/ for doing oauth, which isn't too bad, except that that library will only do the oauth portion, because the Contacts API doesn't support the service discovery API used by the python-api-client. Sigh.

Also came across this post: https://groups.google.com/forum/#!topic/oauth2-dev/unOUxP36Ag8, which indicates that the gdata library only supports oauth 1, but the contacts api only supports oauth2. Sigh.

Ok, more results: I got oauth working, and was able to pull a data set using requests. Hooray!

Time to learn some XML parsing, I guess.
