小ネタです。備忘録

Slack Bolt for pythonを使って外部から取得した画像をSlackにアップロードするには。以下のようなやり方

fileupload.py

import requests

def get_and_upload():
    filename = "test.gif"
    url = "https://lne.st/test.gif" #取得したいファイルの存在するURLを入れる
    urlData = requests.get(url).content
    download_file(url, filename)
    try:
        result = client.files_upload(
            channels=body['channel'],#channel_id を適宜入れること
            file=filename,
        )
        logger.info(result)
        uploadedurl = result['file']['permalink_public']
    except SlackApiError as e:
        print("Error uploading file: {}".format(e))
    finally:
        pass


import urllib.error
import urllib.request
def download_file(url, dst_path):
    try:
        with urllib.request.urlopen(url) as web_file, open(dst_path, 'wb') as local_file:
            local_file.write(web_file.read())
    except urllib.error.URLError as e:
        print(e)
