I'm trying to use slacker on python 2.6.9 and getting the issue below, on 2.7.10 everything works. Upgrading to newer version of python is not possible in my case. Is there any workaround?

I'm getting the following error :

I can't tell if this is just an issue for me, and if so then you can close the issue, but I'm running into the above error when trying to run the example in the readme.

Has anyone run into it before and how are you getting around it if you have? I tried updating pyopenssl but that didn't seem to have any effect.

Hello. I'm trying to post a message with an attachment, but it doesn't seem to work. OR, I'm not using it correctly, in which case, could you please add an example to the README.

This is what I'm trying:

print slack.chat.post_message('#sandbox', 'text', attachments={'fallback':'fallback', 'fields':[{'title':'title','value':'value'}]}).body

All I end up seeing is the message "text" without anything else.

Thanks!

Slack just added 2FA.
In the returned object it looks to be the attribute called 'has_2fa'

Docs:
https://api.slack.com/types/user

Thought I would bring it to your attention if you had not already seen it, and wanted to do some kind of additional functionality off of it.

I'm getting user_not_found and channel_not_found errors when I try to make calls with valid user and channel ids. If I replicate the calls via postman, or by using the python requests library, they go through perfectly. Have there been any changes to the API recently that could have caused this?

Is it possible to invite/deactivate users via slacker / slack api?
Also unfortunately i haven't seen anything regarding that.

Under: https://api.slack.com/methods there is also no mention of the user on/offboarding procedure.

thx.

Hey I didn't see anyway to post a snippet to a group, can this feature be added in?
Thanks!

Any plans for adding more support for the RTM API?

Let me know if I can help at all.

Right now, files.upload requires a file on disk, but it would be great if slacker.files.upload would take (and use) a string instead of a filename.

I'm trying to upload files that I grabbed off the web, and being able to have the following work would be great:

import requests
slack.files.upload(content=requests.get(url).content)
# or
slack.files.upload(url=url)

Upload a file

slack.files.upload('rtmbot.conf')

This does not work for me.

I get slacker.Error: user_is_bot

slackcat

I'm considering using slacker to implement a back-end for Slack on Err but it should, ideally, support Python 2.7 and 3.3+ for that. However, no compatibility is specified anywhere.

Please consider mentioning this in the README and setting appropriate trove classifiers in setup.py.

Very minor, would be convenient to have slacker.__version__ as in https://www.python.org/dev/peps/pep-0396/

Messages posted using chat.post_message() are run through cgi.escape(). This suppresses any internal angle brackets, which means you can't use the slack api formatting conventions for things like inline links or user references.

It should be pretty easy to add a flag to post_message that disables escaping, or something more clever that runs escape (to get rid of quotes and so on) then re-instates angle-brackets that look like slack commands

A slack client that sends too many responses at once can elicit a 429 status code, followed by a json error object saying how many seconds we need to pause.

https://api.slack.com/docs/rate-limits

There are two ways to skin this -- mange the 429 response ourself in BaseAPI._request
which gives us the advantage of being able to pause for exactly the right delay time, -or-
or ask the requests module to simply implement an incremental backoff algorithm to respect 429.

Either solution seems relatively reasonable.

For plan A, by default, requests will -not- retry a 429, so we'll get back the slack error response and can (if enabled by the user) sleep and then retry the request in BaseAPI._request with something vaguely like this (totally untested, and it's late at night when I wrote this):

success = False
while not success:
    response = method ...
    if response.status_code == 429 and self.backoff:
        # get the value of the Retry-after header in the response packet
        sleep(response.<headers>.Retry_after)
        continue
    response.raise_for_status()
    success = True    

For plan B, one would do something like this:

in init, create a session with a retry object on the HTTP adapter:

retries = Retry(status_forcelist={429})
adapter = requests.adapters.HTTPAdapter(retries)
self.session = requests.Session()
self.session.mount('https://', adapter)

and use self.session.get and self.session.post et all instead of requests.get / requests.post as the methods.

reference:

http://docs.python-requests.org/en/master/api/?highlight=retries

On lines 61-62 in slacker/init.py, you raise an exception where response.successful != True. In the WebAPI implementation, the response would simply be yielded with 'ok': 'False' and 'error': '[some error message]'. Wouldn't it make more sense to mimic the WebAPI implementation in this respect and just yield the response as-is? Thanks!

It's a bummer that I have to tell people to install your thing from github before installing ours from pypi :<

User Identity Method

It is bad practice to open\close TCP connection for each api request.

Client must create on __init__ requests.Session and explicitly close it.

Calling slack.files.upload('File 1.txt') will work, but slack.files.upload('File ∑.txt') gives the following error:

slacker.Error: no_file_data

I'm using Python 3

I've pulled latest and followed the install steps (pip install slacker). I can see everything is installed correctly. But my test script fails with an output message saying it fails to load the utils module.

Here are the details.

Installed via PIP

C:\>c:\Python27\Scripts\pip list
pip (8.1.2)
requests (2.10.0)
setuptools (18.2)
slacker (0.9.16)

Contents of my basic script:

Y:\scripts\>type NewScript.py
from slacker import Slacker
slack = Slacker('xxx-myTokenHere-xxx')
# Send a message to #general channel
slack.chat.post_message('#general', 'Hello fellow slackers!')

When I execute I get the following output:

C:\>c:\Python27\python.exe y:\scripts\iFactrPythonScript\NewScript.py
Traceback (most recent call last):
  File "y:\scripts\NewScript.py", line 1, in <module>
    from slacker import Slacker
  File "/Users/[...maskedusername...]/scripts/slacker.py", line 19, in <module>
ImportError: No module named utils

I get the feeling this is because my script is running on a network drive.

For using slash commands and other interactive buttons, you're given the option to respond using the response_url field value instead of just a normal return within the 3 second limit.

file is currently required, but the API doesn't require it if content is specified.

Hi there,

Sorry if this is the wrong avenue to post this on, but here I go.

I want to use slacker in a django app, which will have at least 2 threads, and many components, and I'm wondering what the best way to use the Slacker class is in this case.

Should I use it as a singleton for the project? for the individual app? for each module? for each thread?

Interested in your thoughts.

EDIT: This is a 'question', but it won't let me set the labels.

Posting messages via incoming webhooks allows for attachment only posts that are easier to format.

I am trying to post the following via slacker:

    attachment = {
        "attachments": [
            {
                "fallback": "Fallback text",
                "title": "Title",
                "fields": [
                    {
                        "value": "*some field data*",
                        "short": True
                    },
                    {
                        "value": "*some more data*",
                        "short": True
                    }
                ],
                "mrkdwn_in": ["fields"],
                "color": "good"
            }
        ]
    }
    slacker.chat.post_message(
        SLACK_CHANNEL,
        "Testing Attachments",
        SLACK_USER,
        attachments=attachment,
        icon_url=SLACK_ICON_URL
    )

Where I have set the constants to my settings, but you should be able to test this yourself.

Note, if I use json.dumps(attachment), the result is:

Which contains empty attachments.

When I post a message to a channel, it posts it under the name "Slack API Tester". How can I setup it up or rename?

I don't have a clue about what's going on here, and honestly I can't tell if it's Slack, Slacker, or my issue:

    attachmentdata = json.dumps(
        {
            "attachments": [
                {
                    "fallback": fallback_message,
                    "color": "#ccac55",

                    "title": "New {}: {}".format("selfpost" if submission.is_self == True else "link post", submission.title),
                    "title_link": RedditService.create_shortlink(submission.id),

                    "text": submission.title,

                    "fields": [
                        {
                            "title": "Domain",
                            "value": submission.domain,
                            "short": True
                        },
                        {
                            "title": "Author",
                            "value": "/u/{}".format(submission.author),
                            "short": True
                        }
                    ],

                    "thumb_url": submission.thumbnail,

                    "footer": "r/SpaceX",
                    "footer_icon": "https://spacexstats.com/favicon-194x194.png",
                    "ts": int(submission.created_utc)
                }
            ]
        }
    )

    print(attachmentdata)

    self.slack.chat.post_message('#newposts', "test", as_user=True, attachments=attachmentdata, unfurl_links=True, unfurl_media=True)

This JSON compiles to:

 {"attachments": [{"ts": 1465565991.0, "title_link": "https://redd.it/4ngbu1", "thumb_url": "http://b.thumbs.redditmedia.com/whD2TBHwdLh4WUOQwNl4AFCidqv1Z5QM41rZdC4DNcU.jpg", "text": "dddd", "fallback": "[r/SpaceX] New link post: dddd by /u/EchoLogic https://redd.it/4ngbu1", "footer": "r/SpaceX", "fields": [{"short": true, "value": "reddit.com", "title": "Domain"}, {"short": true, "value": "/u/EchoLogic", "title": "Author"}], "title": "New link post: dddd", "color": "#ccac55", "footer_icon": "https://spacexstats.com/favicon-194x194.png"}]}

Yet, when submitted through using the API, the attachment simply does not appear. If I remove the "text" parameter of post_message, I get a Slack no_text error, which violates their API design:

A message must have either text or attachments or both. The text parameter is required unless you provide attachments. You can use both parameters in conjunction with each other to create awesome messages.

What's the deal here?

Hi all,

can I use slacker for msg sending to Slack private channel?
https://get.slack.help/hc/en-us/articles/201925108-Understanding-channels-and-DMs
I am use Bots.
My bot is currently in python private group.
Code:

from slacker import Slacker

slack_token = "xxxx-xxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxx"
slack_channel = "#python"
slack_msg = "Hello, world!"

slack = Slacker(slack_token)
slack.chat.post_message(slack_channel, slack_msg)

Traceback:

Traceback (most recent call last):
  File "./slack.py", line 11, in <module>
    slack.chat.post_message(slack_channel, slack_msg)
  File "/usr/local/lib/python2.7/dist-packages/slacker/__init__.py", line 287, in post_message
    'icon_emoji': icon_emoji
  File "/usr/local/lib/python2.7/dist-packages/slacker/__init__.py", line 71, in post

  File "/usr/local/lib/python2.7/dist-packages/slacker/__init__.py", line 63, in _request
    raise Error(response.error)
slacker.Error: channel_not_found

Also I tried slack_channel = "python".
The code works for public channels (for example: #general channel).

Hi i noticed that you added parse option to chat.update but you might have forgotten to actually pass the variable to the post method is that intentional or was that mistake?

def update(self, channel, ts, text, attachments=None, parse=None,
               link_names=False, as_user=None):
        # Ensure attachments are json encoded
        if attachments and isinstance(attachments, list):
            attachments = json.dumps(attachments)
        return self.post('chat.update',
                         data={
                             'channel': channel,
                             'ts': ts,
                             'text': text,
                             'attachments': attachments,
                             'parse': None, #<--------------- change here
                             'link_names': int(link_names),
                             'as_user': as_user,
})

shouldnt this be

  def update(self, channel, ts, text, attachments=None, parse=None,
               link_names=False, as_user=None):
        # Ensure attachments are json encoded
        if attachments and isinstance(attachments, list):
            attachments = json.dumps(attachments)
        return self.post('chat.update',
                         data={
                             'channel': channel,
                             'ts': ts,
                             'text': text,
                             'attachments': attachments,
                             'parse': parse, #<--------------- change here
                             'link_names': int(link_names),
                             'as_user': as_user,
})

otherwise the param in the function is pointless.

When trying to upload an empty file (ex: error logs... in lucky cases), i'm getting error:

 File "/var/www/venv/local/lib/python2.7/site-packages/slacker/__init__.py", line 427, in upload
   files={'file': f})
 File "/var/www/venv/local/lib/python2.7/site-packages/slacker/__init__.py", line 70, in post
   return self._request(requests.post, api, **kwargs)
 File "/var/www/venv/local/lib/python2.7/site-packages/slacker/__init__.py", line 62, in _request
   raise Error(response.error)
Error: no_file

Just tried to put a symbol in file and error disappeared.

Thank you.

I was faced with next problem:
When I try to send message with attachments and without text I'm catching exception
But Slack provides sending message with empty text and attachments, as you can see picture below

Hope you fix that:)

It is new method provided for creating new RTM connection

I've been unable to fully establish a persistent connections to Slack so that the bot appears as "Active" in the DM list. This functionality is available in the official Slack Python library but I can't seem to get it to work here.

I'm trying to upload a local txt file to a channel
slack.files.upload('blah.txt', channels='channelname'')

am I doing something wrong here.

Hi!

Your setup.py contains trove classifiers, but they aren't showing up on slacker's PyPI page for some reason:

https://pypi.python.org/pypi/slacker/0.9.29

I don't know why not, maybe it's as simple as that fact that your classifiers are in a tuple and not a list?

The classifiers not showing means that tools like caniusepython3 list slacker as "not supporting Python 3" when the code, and travis configuration, suggests that it does.

When I try to post a message I get this warning

In [1]: from slacker import Slacker
In [2]: slack = Slacker('abc-123')
