Introduction #

SmartChart’s Single Sign-On (SSO) allows users from third-party systems to log in directly to the SmartChart platform using an encrypted token — no username/password required. The token uses SHA1 algorithm based on a secret key, timestamp, and username, effectively preventing forgery. Unlike single-page embedding, SSO login grants access to the entire platform, not just specific reports.

SSO Integration #

'/echart/smart_login?id=xxx&stamp=xxx&token=xxx&url=/'

Parameters:
id: Username (managed in SmartChart platform)
stamp: Timestamp (milliseconds since Jan 1, 1970)
token: SHA1 encrypted, token = SHA1(link_key + stamp + id)
       Set environment variable SMART_KEY = link_key on the SmartChart server
url: Redirect URL after successful login

Python Example #

import time
import hashlib
import os

SMART_CHART_URL = 'http://127.0.0.1:8000'
LOGIN_URL = SMART_CHART_URL + '/echart/smart_login?id={id}&stamp={stamp}&token={token}&url={url}'
SMART_KEY = 'link_key'

def get_smarturl(username, url='/'):
    stamp = int(time.time() * 1000)
    id = username
    res = SMART_KEY + str(stamp) + id
    token = hashlib.sha1(res.encode('utf-8')).hexdigest()
    LOGIN_DICT = {
        "id": id,
        "stamp": stamp,
        "token": token,
        "url": url
    }
    visit_url = LOGIN_URL.format(**LOGIN_DICT)
    return visit_url
