MD5，SHA256，时间戳获取

import hashlib

# MD5加密

def jiamimd5(src):

　　m = hashlib.md5()

　　m.update(src.encode('UTF-8'))

　　return m.hexdigest()

=====================================

import time

print(time.time) # 获取时间戳,浮点型

stam = int(time.time) # 转整形

priint(stam) #得到时间戳

================================

import hmac i

mport hashlib

appkey = "需要申请"

strToSign = "根据文档规则生成"

# hmac_sha256加密

signature = hmac.new(bytes(appkey, encoding='utf-8'), bytes(strToSign, encoding='utf-8'), digestmod=hashlib.sha256).digest()

# print(signature)

# 二进制转为

HEX HEX = signature.hex()

# print(HEX)

# 将字符串换为小写

lowsigne = HEX.lower()
