您目前无法使用传入 Webhooks API 附加文件。您需要使用Mattermost 客户端 API来发布附有文件的帖子。
这是一个如何实现这一目标的示例(使用 Mattermost API v3 for Mattermost >= 3.5)
SERVER_URL = "http://chat.example.com/"
TEAM_ID = "team_id_goes_here"
CHANNEL_ID = "channel_id_goes_here"
USER_EMAIL = "you@example.com"
USER_PASS = "password123"
FILE_PATH = '/home/user/thing_to_upload.png'
import requests, json, os
# Login
s = requests.Session() # So that the auth cookie gets saved.
s.headers.update({"X-Requested-With": "XMLHttpRequest"}) # To stop Mattermost rejecting our requests as CSRF.
l = s.post(SERVER_URL + 'api/v3/users/login', data = json.dumps({'login_id': USER_EMAIL, 'password': USER_PASS}))
USER_ID = l.json()["id"]
# Upload the File.
form_data = {
"channel_id": ('', CHANNEL_ID),
"client_ids": ('', "id_for_the_file"),
"files": (os.path.basename(FILE_PATH), open(FILE_PATH, 'rb')),
}
r = s.post(SERVER_URL + 'api/v3/teams/' + TEAM_ID + '/files/upload', files=form_data)
FILE_ID = r.json()["file_infos"][0]["id"]
# Create a post and attach the uploaded file to it.
p = s.post(SERVER_URL + 'api/v3/teams/' + TEAM_ID + '/channels/' + CHANNEL_ID + '/posts/create', data = json.dumps({
'user_id': USER_ID,
'channel_id': CHANNEL_ID,
'message': 'Post message goes here',
'file_ids': [FILE_ID,],
'create_at': 0,
'pending_post_id': 'randomstuffogeshere',
}))
