QCloud Signature Version 3 Signing Process with python requests

QCloud TC3-HMAC-SHA256 signature is basically a fork of AWSv4. This library can help you to call API directly using Requests, so you can avoid the freaking other library, if you want.

Use at client with requests

import qcloud_auth
import requests

auth_plugin = qcloud_auth.QCloudRequestsAuth("AKID****************", 
                                             "****************",
                                             "cvm.tencentcloudapi.com",
                                             "ap-guangzhou",
                                             "cvm",
                                             "DescribeInstances",
                                             "2017-03-12"
                                             )
ret = requests.get("https://cvm.tencentcloudapi.com/", auth=auth_plugin)
