Python实现接口署名调用

1、第三方接口署名调用

1. import json
2. import requests
3. import hashlib
4. import time
5. import hmac
6. access_key = 'xxxxxxxxxxxxxxx'
7. secret_key = 'xxxxxxxxxxxxxxx'
8. # 应用信息
9. def _wps4_sig(method, url, date, body):   
10.     print(body)
11.     if body is None:
12.         bodySha = ""
13.     else:
14.         bodySha = hashlib.sha256(body.encode('utf-8')).hexdigest()
16.     content = "xxx-4" + method + url
