Sample (Python)

It will show how to generate signature by using Python, and show a sample to request API.

1. Sample for Signature

#coding=utf-8

import hashlib
import hmac
import time
from random import randint

###Configure APP SERVER###
api_server = "https://cdn-api-dev.swiftfederation.com"

def signature():
    ###Paste your access key id!!!###
    access_key_id="V265i4K31j991E19"
    ###Paste your access key secret!!!###
    access_key_secret="06427n2vLExuYH3cn7v5GG1MeYQ7n6S3"

    request_method = "POST"
    uri = "/v1.0/report/bandwidth"
    request_timestamp = time.strftime("%Y%m%dT%H%M%SZ", time.localtime(time.time() + time.timezone))
    nonce = str(randint(10000, 99999))
    request_body = '{"domains":["cycdnml.yuanzhanapp.com"],"startTime":"2018-12-16T00:00:00Z","endTime":"2018-12-16T00:20:00Z"}'

    '''Caculate signature'''
    signing_string = "%s\n%s\n%s\n%s\n%s\n%s" % (request_method.upper(), uri, request_timestamp, nonce, access_key_id, request_body)
    signature = hex_hmac_sha256(access_key_secret, signing_string)
    '''Assemble Authroization value'''
    authorization_val = "HMAC-SHA256 " + access_key_id + ":" + signature

    print "================ Signature ==================="
    print("signature: %s" % signature)
    print("")

'''hex hamc sha256 algorithm'''
def hex_hmac_sha256(sign_key, signing_string):
    signed_bytes = hmac.new(sign_key, signing_string, digestmod=hashlib.sha256).digest()
    return signed_bytes.encode('hex')

signature()

2. Sample for API Request

refer to Get Bandwidth

2.1. Get Bandwidth

  • API URL:
https://cdn-api.swiftfederation.com/v1.1/report/bandwidth
  • Request Method:
POST
  • Request Header:
Authorization: HMAC-SHA256 V265i4K31j991E19:016fc06ec61ce4ba2faf34f3c35c85b6fffe5c6811f9829d2d32a241c5e7f391
Content-Type: application/json; charset=utf-8
x-sfd-date: 20181218T021551Z
x-sfd-nonce: 64593
  • Request Body Example
{
    "domains": [
        "www.example1.com",
        "www.example2.com"
    ],
    "startTime": "2018-03-29T17:35:00Z",
    "endTime": "2018-03-29T17:45:00Z",
    "fillFixedTime": "false",
    "interval": "minute"
}

2.2. Request Get Bandwidth API

Please replace 3 parts commented by '###' as below:

  • api_server
  • access_key_id
  • access_key_secret
#coding=utf-8

import json
import traceback
import urllib2
import hashlib
