Feature Request: be able to post a file to slack

[mccare]

Description

We are using https://github.com/adrey/slack-file-upload-action to upload a file. Would be great if slackapi would also support this method.

What type of issue is this? (place an x in one of the [ ])

This would be great!

[shalva97]

This is the only feature that is missing for my workflow to be perfect

[govindgupta1103]

Is any verified GitHub actions tool available to send the file to Slack? We are not allowed to use unverified tools.

[shalva97]

You can use Slack API directly for example:

      - name: Upload file to Slack
        run: >
          curl -F file=@app/build/outputs/apk/production/release/app-production-release.apk
          -F "initial_comment=Android production variant APK"
          -F channels=mobile-builds-android
          -H "Authorization: Bearer ${{ secrets.SLACK_BOT_TOKEN }}"
          https://slack.com/api/files.upload

Of course it is not perfect, but it works

Hi Shalva, where is the file location? Actually I want to attach an artifact which is generated using GitHub actions.

[shalva97]

It is specified after @ symbol

curl -F file=@your-file-here.txt

directory will be your repository root. Check https://api.slack.com/methods/files.upload for more info

[govindgupta1103]

Hi Shalva, so does this method support only the json files or any other file type?
Because I want to upload an excel file to Slack

[govindgupta1103]

curl -F file=@app/build/outputs/apk/production/release/app-production-release.apk

Shouldn't file be in double quotes?

[govindgupta1103]

Did it work for you Shelva ?

[shalva97]

yes, thats what I use in my project. It does not need double queotes. I think its better to ask it somewhere else, because this issue is for a feature request...

[govindgupta1103]

Shalva , I know, but the requested feature is posting a file to Slack. I spent 5 hours today trying to send an excel file using above command but in vain

[govindgupta1103]

@srajiang Can you please confirm if we can send excel file to Slack using the commands provided by @shalva97 .

[gauravcanon]

@govindgupta1103 Yes for me it is working fine sending an Excel sheet.

[govindgupta1103]

For me too it worked. Thanks

@seratch , I would like to contribute to this feature. can I take this up?

[derekmurawsky]

I'd love to see this feature added as well. From an implementation perspective, I see it needing to be a two step process to support the nice formatting/block style messages which don't seem to be supported by the upload API (I haven't thoroughly checked this yet, though).

1. Upload the file generically using the upload API and note the TS
2. Update the message TS with the standard message API, thus supporting blocks.

It's 2024 and this feature would be a great addition!!

[amrgetment]

any updates

[MatthewCane]

It looks like this feature is part of the proposed additions to a v2 of the Action, see #312

[zimeg]

👋 Hello! We're so excited to share that as part of the @v2.0.0 release that @MatthewCane hinted at, this is now possible!

More detailed notes on updating to the latest version are noted in that release and are also in the README, but a snippet to upload files might resemble this:

- name: Share a file to that channel
  uses: slackapi/slack-github-action@v2.0.0
  with:
    method: files.uploadV2
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    payload: |
      channel: ${{ secrets.SLACK_CHANNEL_ID }}
      initial_comment: "the results are in!"
      file: "./path/to/results.out"
      filename: "results-${{ github.sha }}.out"

With the files:write scope attached to the token, files should be uploading to the channel your bot has been added to!

For now, we can close this issue, but if anyone is finding issues with file uploads, please feel free to open a new issue 🙏 ✨

@zimeg I use payload with markdown like the following payload, I wonder how to migrate my json payload to the new version

  - name: 'Post release notes to Slack'
    uses: 'slackapi/slack-github-action@v1.26.0'
    with:
      channel-id: ${{ secrets.SLACK_FILES_CHANNEL_ID }}
      payload: |
        {
        "blocks": [
           {
            "type": "section",
            "text": {
              "type": "mrkdwn",
              "text": "*Release notes*"
            }
          },
           {
            "type": "section",
            "text": {
              "type": "mrkdwn",
              "text": "${{ steps.extract_release_note.outputs.release_note }}"
            }
          }
        ]
        }

[zimeg]

@amrgetment At a glance that snippet seems to be sending the release notes as a message with perhaps a bot token?

Please let me know if I've misunderstood this setup, but I'd recommend checking out this example in the README for a change something like:

- name: "Post release notes to Slack"
  uses: slackapi/slack-github-action@v2.0.0
  with:
    method: chat.postMessage
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    payload: |
      channel: ${{ secrets.SLACK_FILES_CHANNEL_ID }}
      text: "Release notes have been shared"
      blocks:
        - type: section
          text:
            type: mrkdwn
            text: "*Release notes*"
        - type: section
          text:
            type: mrkdwn
            text: "${{ steps.extract_release_note.outputs.release_note }}"

Also note that this includes the bot token and the payload also should include a top-level text value! I'm hoping this helps, but if let me know if I'm misunderstanding or if something else seems off in a new issue 🙏
