- Three numbers with colons, USER:POST:SHARD: 12:34:63 (We’re guessing that the third part is a shard in some FB internal system. In our experience so far, it’s always either 63 or the app-scoped user id for 63.)
- Two numbers with colon, POST:SHARD: 12:34 (We’ve seen 0 as shard in this format.)
- Four numbers with colons/underscore, USER:POST:SHARD_COMMENT: 12:34:63_56

Return type:
-
resolve_object_id
(user_id, post_id, activity=None)[source]¶ Resolve a post id to its Facebook object id, if any.
Used for photo posts, since Facebook has (at least) two different objects (and ids) for them, one for the post and one for each photo.
This is the same logic that we do for canonicalizing photo objects in get_activities() above.
If activity is not provided, fetches the post from Facebook.
Parameters: - user_id – string Facebook user id who posted the post
- post_id – string Facebook post id
- activity – optional AS activity representation of Facebook post

and passes through the access token.Parameters: _as – if not None, parses the response as JSON and passes it through _as() with this type. if None, returns the response object. Returns: decoded JSON object or urlopen response object
-
urlopen_batch
(urls)[source]¶ Sends a batch of multiple API calls using Facebook’s batch API.
Raises the appropriate
urllib2.HTTPError
if any individual call returns HTTP status code 4xx or 5xx.https://developers.facebook.com/docs/graph-api/making-multiple-requests
Parameters: urls – sequence of string relative API URLs, e.g. (‘me’, ‘me/accounts’) Returns: sequence of responses, either decoded JSON objects (when possible) or raw string bodies
-
urlopen_batch_full
(requests)[source]¶ Sends a batch of multiple API calls using Facebook’s batch API.
Similar to urlopen_batch(), but the requests arg and return value are dicts with headers, HTTP status code, etc. Only raises
urllib2.HTTPError
if the outer batch request itself returns an HTTP error.https://developers.facebook.com/docs/graph-api/making-multiple-requests
Parameters: requests – sequence of dict requests in Facebook’s batch format, except that headers is a single dict, not a list of dicts, e.g.:
[{'relative_url': 'me/feed', 'headers': {'ETag': 'xyz', ...}, }, ... ]
Returns: sequence of dict responses in Facebook’s batch format, except that body is JSON-decoded if possible, and headers is a single dict, not a list of dicts, e.g.: [{'code': 200, 'headers': {'ETag': 'xyz', ...}, 'body': {...}, }, ... ]
-
flickr¶
Flickr source class.
Uses Flickr’s REST API https://www.flickr.com/services/api/
TODO: Fetching feeds with comments and/or favorites is very request intensive right now. It would be ideal to find a way to batch requests, make requests asynchronously, or make better calls to the API itself. Maybe use flickr.activity.userPhotos (https://www.flickr.com/services/api/flickr.activity.userPhotos.html) when group_id=SELF.
googleplus¶
Google+ source class.
The Google+ API currently only returns public activities and comments, so the Audience Targeting ‘to’ field is always set to @public. https://developers.google.com/+/api/latest/activities/list#collection
-
class
granary.googleplus.
GooglePlus
(auth_entity=None, access_token=None)[source]¶ Bases:
granary.source.Source
Implements the ActivityStreams API for Google+.
The Google+ API already exposes data in ActivityStreams format, so this is just a pass through.
-
__init__
(auth_entity=None, access_token=None)[source]¶ Constructor.
Currently, only auth_entity is supported. TODO: implement access_token.
Parameters: - access_token – string OAuth access token
- auth_entity – oauth-dropins.googleplus.GooglePlusAuth
-
get_actor
(user_id=None)[source]¶ Returns a user as a JSON ActivityStreams actor dict.
Parameters: user_id – string id or username. Defaults to ‘me’, ie the current user. Raises: GooglePlusAPIError
-
get_activities_response

See method docstring in source.py for details. app_id is ignored.
Replies (comments), likes (+1s), and shares (reshares) each need an extra API call per activity. The activity has total counts for them, though, so we only make those calls when we know there’s something to fetch. https://developers.google.com/+/api/latest/comments/list https://developers.google.com/+/api/latest/people/listByActivity
We also batch those calls into a single HTTP request, so there are at most two HTTP requests total, one to get activities and optionally one to get new responses. https://developers.google.com/api-client-library/python/guide/batch
Mentions are not currently fetched or included because the API doesn’t explicitly support searching for them. It could be approximated, though: https://github.com/snarfed/bridgy/issues/523#issuecomment-155523875
-
get_comment
(comment_id, activity_id=None, activity_author_id=None, activity=None)[source]¶ Returns an ActivityStreams comment object.

instagram¶
Instagram source class.
Instagram’s API doesn’t tell you if a user has marked their account private or not, so the Audience Targeting ‘to’ field is currently always set to @public. http://help.instagram.com/448523408565555 https://groups.google.com/forum/m/#!topic/instagram-api-developers/DAO7OriVFsw https://groups.google.com/forum/#!searchin/instagram-api-developers/private

-
__init__
(access_token=None, allow_comment_creation=False, scrape=False)[source]¶ Constructor.

See method docstring in source.py for details. app_id is ignored. Supports min_id, but not ETag, since Instagram doesn’t support it.
http://instagram.com/developer/endpoints/users/#get_users_feed http://instagram.com/developer/endpoints/users/#get_users_media_recent
Likes are always included, regardless of the fetch_likes kwarg. They come bundled in the ‘likes’ field of the API Media object: http://instagram.com/developer/endpoints/media/#
Mentions are never fetched or included because the API doesn’t support searching for them. https://github.com/snarfed/bridgy/issues/523#issuecomment-155523875
Shares are never fetched included since there is no share feature.
Instagram only supports search over hashtags, so if search_query is set, it must begin with #.
May populate a custom ‘ig_like_count’ property in media objects. (Currently only when scraping.)
Parameters: - scrape – if True, scrapes HTML from instagram.com instead of using the API. Populates the user’s actor object in the ‘actor’ response field. Useful for apps that haven’t yet been approved in the new permissions approval process. Currently only supports group_id=SELF.

Subclasses should override this. See
get_activities()
for an alternative that just returns the list of activities.If user_id is provided, only that user’s activity(s) are included. start_index and count determine paging, as described in the spec: http://activitystrea.ms/draft-spec.html#anchor14
app id is just object id: http://opensocial-resources.googlecode.com/svn/spec/2.0/Social-Data.xml#appId
group id is string id of group or @self, @friends, @all, @search: http://opensocial-resources.googlecode.com/svn/spec/2.0/Social-Data.xml#Group-ID
The fetch_* kwargs all default to False because they often require extra API round trips. Some sources return replies, likes, and shares in the same initial call, so they may be included even if you don’t set their kwarg to True.
Parameters: - user_id – string, defaults to the currently authenticated user
- group_id – string, one of '@self‘, '@all‘, '@friends‘, '@search‘. defaults to '@friends‘
- app_id – string
- activity_id – string
- start_index – int >= 0
- count – int >= 0
- etag – string, optional ETag to send with the API request. Results will only be returned if the ETag has changed. Should include enclosing double quotes, e.g. ‘“ABC123”’
- min_id – only return activities with ids greater than this
- cache – object with get(key), set_multi(dict), and delete_multi(list) methods. In practice, this is App Engine’s memcache interface: https://developers.google.com/appengine/docs/python/memcache/functions Used to cache data that’s expensive to regenerate, e.g. API calls.
- fetch_replies – boolean, whether to fetch each activity’s replies also
- fetch_likes – boolean, whether to fetch each activity’s likes also
- fetch_shares – boolean, whether to fetch each activity’s shares also
- fetch_events – boolean, whether to fetch the user’s events also
- fetch_mentions – boolean, whether to fetch posts that mention the user
- search_query – string, an optional search query, only for use with @search group_id
- kwargs – some sources accept extra kwargs. See their docs for details.
Returns: - response values based on OpenSocial ActivityStreams REST API.
http://opensocial-resources.googlecode.com/svn/spec/2.0.1/Social-API-Server.xml#ActivityStreams-Service http://opensocial-resources.googlecode.com/svn/spec/2.0.1/Core-Data.xml
It has these keys: * items: list of activity dicts * startIndex: int or None * itemsPerPage: int * totalResults: int or None (e.g. if it can ‘t be calculated efficiently) * filtered: False * sorted: False * updatedSince: False * etag: string etag returned by the API’s initial call to get activities
Return type: Raises: ValueError
– if any argument is invalid for this sourceNotImplementedError
– if the source doesn’t support the requested operation, e.g. Facebook doesn’t support search.

original_post_discovery
(activity, domains=None, cache=None, include_redirect_sources=True, **kwargs)[source]¶ Discovers original post links.
This is a variation on http://indiewebcamp.com/original-post-discovery . It differs in that it finds multiple candidate links instead of one, and it doesn’t bother looking for MF2 (etc) markup because the silos don’t let you input it. More background: https://github.com/snarfed/bridgy/issues/51#issuecomment-136018857
Original post candidates come from the upstreamDuplicates, attachments, and tags fields, as well as links and permashortlinks/permashortcitations in the text content.
Parameters: - activity – activity dict
- domains – optional sequence of domains. If provided, only links to these domains will be considered original and stored in upstreamDuplicates. (Permashortcitations are exempt.)
- cache – optional, a cache object for storing resolved URL redirects. Passed to follow_redirects().

is_public
(obj)[source]¶ Returns True if the object is public, False if private, None if unknown.
...according to the Audience Targeting extension https://developers.google.com/+/api/latest/activities/list#collection
Expects values generated by this library: objectType group, alias @public or @private.
Also, important point: this defaults to true, ie public. Bridgy depends on that and prunes the to field from stored activities in Response objects (in bridgy/util.prune_activity()). If the default here ever changes, be sure to update Bridgy’s code.
-
static
add_rsvps_to_event
(event, rsvps)[source]¶ Adds RSVP objects to an event’s attending fields, in place.

static
activity_changed
(before, after, log=False)[source]¶ Returns whether two activities or objects differ meaningfully.
Only compares a few fields: object type, verb, content, location, and image. Notably does not compare author and published/updated timestamps.
This has been tested on Facebook posts, comments, and event RSVPs (only content and rsvp_status change) and Google+ posts and comments (content, updated, and etag change). Twitter tweets and Instagram photo captions and comments can’t be edited.
Parameters: after (before,) – dicts, ActivityStreams activities or objects Returns: boolean
-
base_object
(obj)[source]¶ Returns the ‘base’ silo object that an object operates on.
For example, if the object is a comment, this returns the post that it’s a comment on. If it’s an RSVP, this returns the event. The id in the returned object is silo-specific, ie not a tag URI.
Subclasses may override this.
Parameters: obj – ActivityStreams object Returns: dict, minimal ActivityStreams object. Usually has at least id; may also have url, author, etc.

class
granary.twitter.
Twitter
(access_token_key, access_token_secret, username=None)[source]¶ Bases:
granary.source.Source
Implements the ActivityStreams API for Twitter.
-
__init__
(access_token_key, access_token_secret, username=None)[source]¶ Constructor.
Twitter now requires authentication in v1.1 of their API. You can get an OAuth access token by creating an app here: https://dev.twitter.com/apps/new
Parameters: - access_token_key – string, OAuth access token key
- access_token_secret – string, OAuth access token secret
- username – string, optional, the current user. Used in e.g. preview/create.
-
get_actor
(screen_name=None)[source]¶ Returns a user as a JSON ActivityStreams actor dict.
Parameters: screen_name – string username. Defaults to the current user.
-
get_activities_response
(user_id=None, group_id=None, app_id=None, activity_id=None, start_index=0, count=0, etag=None, min_id=None, cache=None, fetch_replies=False, fetch_likes=False, fetch_shares=False, fetch_events=False, fetch_mentions=False, search_query=None, **kwargs)[source]¶ Fetches posts and converts them to ActivityStreams activities.
XXX HACK: this is currently hacked for bridgy to NOT pass min_id to the request for fetching activity tweets themselves, but to pass it to all of the requests for filling in replies, retweets, etc. That’s because we want to find new replies and retweets of older initial tweets. TODO: find a better way.
See
source.Source.get_activities_response()
for details. app_id is ignored. min_id is translated to Twitter’s since_id.The code for handling ETags (and 304 Not Changed responses and setting If-None-Match) is here, but unused right now since Twitter evidently doesn’t support ETags. From https://dev.twitter.com/discussions/5800 : “I’ve confirmed with our team that we’re not explicitly supporting this family of features.”
Likes (ie favorites) are scraped from twitter.com HTML, since Twitter’s REST API doesn’t offer a way to fetch them. You can also get them from the Streaming API, though, and convert them with streaming_event_to_object(). https://dev.twitter.com/docs/streaming-apis/messages#Events_event
Shares (ie retweets) are fetched with a separate API call per tweet: https://dev.twitter.com/docs/api/1.1/get/statuses/retweets/%3Aid
However, retweets are only fetched for the first 15 tweets that have them, since that’s Twitter’s rate limit per 15 minute window. :( https://dev.twitter.com/docs/rate-limiting/1.1/limits
Quote tweets are fetched by searching for the possibly quoted tweet’s ID, using the OR operator to search up to 5 IDs at a time, and then checking the quoted_status_id_str field https://dev.twitter.com/overview/api/tweets#quoted_status_id_str
Use the group_id @self to retrieve a user_id’s timeline. If user_id is None or @me, it will return tweets for the current API user.
group_id can be used to specify the slug of a list for which to return tweets. By default the current API user’s lists will be used, but lists owned by other users can be fetched by explicitly passing a username to user_id, e.g. to fetch tweets from the list @exampleuser/example-list you would call get_activities(user_id=’exampleuser’, group_id=’example-list’).
Twitter replies default to including a mention of the user they’re replying to, which overloads mentions a bit. When fetch_shares is True, we determine that a tweet mentions the current user if it @-mentions their username and:
- it’s not a reply, OR
- it’s a reply, but not to the current user, AND * the tweet it’s replying to doesn’t @-mention the current user
-
fetch_replies
(activities, min_id=None)[source]¶ Fetches and injects Twitter replies into a list of activities, in place.

-
fetch_mentions
(username, tweets, min_id=None)[source]¶ Fetches a user’s @-mentions and returns them as ActivityStreams.
