MD5加密：
1。对请求的参数进行ascill码排序 ---> dict(sorted(dict1.items(),key=lambda item:item[0]))
2。对url 进行encode编码  --->datas = parse.urlencode(req)
3。做MD5加密   生成sign(密钥) --->     MDfive = hashlib.md5()
                        MDfive.update(datas.encode('utf-8')
                        return MDfive.hexdigest()
