4. Sample Code

The following shows the sample code of calling with python:

# -*- coding: utf-8 -*-
# ! python3.6

import requests
import uuid
import base64

host = "https://ai.jocloud.com"

appid = 123456789  # Your Service id
restful_id = '********************'  # Your certificate ID
restful_secret = '********************'  # Your certificate key
traceid = str(uuid.uuid4())
dataid = str(uuid.uuid4())

# url
url = host + '/app/%s/v1/text/sync?traceId=%s' % (appid, traceid)

# headers
headers = {
    "content-type": "application/json"
}

auth = base64.b64encode(("%s:%s" % (restful_id, restful_secret)).encode('utf-8'))
headers['token'] = 'Base ' + auth.decode()

text = "Welcome to the text audit interface!!"

# content
values = {
    'actions': ['antispam'],
    'data': [
        {
            'dataId': dataid,
            'dataType': 'BASE64',
            'content': base64.b64encode(text.encode('utf-8')).decode(),
            'extra': {'lang': 'chinese'},
            'context': {'uid': 12345, 'sid': 3467}
        }
    ]
}

# request
res = requests.post(url, json=values, headers=headers)
print('code=%s, data=%s\n' % (res.status_code, res.text))
