Hari Prashant Bhimaraju fd0b013bcd slack_incoming: Handle optional attachment fields aptly.
This commit checks for null values for keys within "attachment" in
the Slack integration's incoming payloads. These keys were expected
to exist optionally previously, and the existence of null values for
these wasn't anticipated. Due to an issue report for such null
values in the payload, their handling is updated appropriately.

The checks for these values are truthiness checks since the strategy
for these values being null or falsy ("", 0) is the same; we don't
process that key-value pair. This is consistent with how Slack handles
this scenario.

For the case where all the attachment fields have null values, Slack
displays this as an empty block with no content, and therefore our
strategy for this is a no-op.

Tests updated.

Alex Vandiver bc25f016fc slack_incoming: Support more syntax.
This significantly extends the accepted support for Slack "blocks"[1], as
well as their legacy "attachments"[2] syntax.

Fixes: #21944.

See also #22228, which this does not solve, but assuming we can decide
which compromises to make, becomes a reasonably uncomplicated follow-up.

Christopher Chong b6f6f6db8d slack_incoming: Process request payload directly in view.py.
slack_incoming webhook previously used has_request_variables to
extract payload from HttpRequest object first, before trying to
access HttpRequest.body again in view.py. This caused an error
when one sends a request without payload - it is forbidden to
read from request data stream twice.

Instead of relying on has_request_variables, this PR extracts
payload depending on content type in view.py directly to avoid
reading request data stream twice.

Fixes #19056.

Alex Vandiver 43f3f9221d slack_incoming: Handle explicit None text payload in webhook. 2021-07-15 09:37:39 -07:00
PIG208 5ecbfecd77 webhook: Rename FIXTURE_DIR_NAME to WEBHOOK_DIR_NAME.
Since FIXTURE_DIR_NAME is the name of the folder that contains the view
and tests modules of the webhook and another folder called "fixtures" that
store the fixtures, it is more appropriate to call it WEBHOOK_DIR_NAME,
especially when we want to refer to the view module using this variable.

akshatdalton 8d158852fd webhooks/slack_incoming: Update regex to correctly convert emphasis.
This was a bug where we were converting _text_ to **text**.
For emphasis we use the *text* format.

Steve Howell 388053db6b webhook tests: Rename main helper to check_webhook.
Almost all webhook tests use this helper, except a few
webhooks that write to private streams.

Being concise is important here, and the name
`self.send_and_test_stream_message` always confused
me, since it sounds you're sending a stream message,
and it leaves out the webhook piece.

We should consider renaming `send_and_test_private_message`
to something like `check_webhook_private`, but I couldn't
decide on a great name, and it's very rarely used.  So
for now I just made sure the docstrings of the two
sibling functions reference each other.

Chris Heald c80e913c7a webhooks: Add a webhook capable of parsing Slack payloads.
This adds a webhook that can be used to interpret standard Slack
payloads. Since there are a ton of existing Slack integrations out
there, having a webhook which can accept standard Slack payloads can
significantly ease transition pains. Obviously this can't do everything
that Slack payloads can (particularly WRT their widgets/interactions),
but we can ingest text and parse out multi-block payloads into a message
relatively reasonably.
