日志记录：

　　调用同一个对象，分别记录错误日志和运行日志

自定义日志类：

class Logger(object):
    __instance = None           

    def __init__(self):
        self.run_log_file = settings.RUN_LOG_FILE
        self.error_log_file = settings.ERROR_LOG_FILE
        self.run_logger = None
        self.error_logger = None

        self.initialize_run_log()
        self.initialize_error_log()

    def __new__(cls, *args, **kwargs):              # 单例模式
        if not cls.__instance:
            cls.__instance = object.__new__(cls, *args, **kwargs)
        return cls.__instance

    @staticmethod
    def check_path_exist(log_abs_file):
        log_path = os.path.split(log_abs_file)[0]
        if not os.path.exists(log_path):
            os.mkdir(log_path)

    def initialize_run_log(self):
        self.check_path_exist(self.run_log_file)
        file_1_1 = logging.FileHandler(self.run_log_file, 'a', encoding='utf-8')
        fmt = logging.Formatter(fmt="%(asctime)s - %(levelname)s :  %(message)s")
        file_1_1.setFormatter(fmt)
        logger1 = logging.getLogger('run_log')          # 'run_log' 随意写
        logger1.setLevel(logging.INFO)                  # 效果与error里logging.Logger一样
        logger1.addHandler(file_1_1)
        self.run_logger = logger1

    def initialize_error_log(self):
        self.check_path_exist(self.error_log_file)
        file_1_1 = logging.FileHandler(self.error_log_file, 'a', encoding='utf-8')
        fmt = logging.Formatter(fmt="%(asctime)s  - %(levelname)s :  %(message)s")
        file_1_1.setFormatter(fmt)
        logger1 = logging.Logger('run_log', level=logging.ERROR)
        logger1.addHandler(file_1_1)
        self.error_logger = logger1

    def log(self, message, mode=True):
        """
        写入日志
        :param message: 日志信息
        :param mode: True表示运行信息，False表示错误信息
        :return:
        """
        if mode:
            self.run_logger.info(message)
        else:
            self.error_logger.error(message)

调用方式： 

if ret['code'] == 1000:
    print(IP,'更新成功')
    Logger().log(ret['message'], True)
else:
    Logger().log(ret['message'], False)

　　

API认证：　

　　密钥串+时间戳发送进行认证，超过超时时间认证失败，认证过的密钥过时清空

客户端：

import hashlib
import time
import requests

class Client(object):

    def __init__(self):
        self.key = '299095cc-1330-11e5-b06a-a45e60bec08b'
        self.key_name = 'auth-key'
        self.asset_api = 'http://127.0.0.1:8000/api/'

    def auth_key(self):
        """
        接口认证
        """
        ha = hashlib.md5(self.key.encode('utf-8'))      # 用self.key 做加密盐
        time_span = time.time()
        ha.update(bytes("%s|%f" % (self.key, time_span), encoding='utf-8'))
        encryption = ha.hexdigest()
        result = "%s|%f" % (encryption, time_span)
        return {self.key_name: result}

    def get_asset(self):
        """
        post方式向街口提交资产信息
        """
        headers = {}
        headers.update(self.auth_key())
        response = requests.get(
            url=self.asset_api,
            headers=headers,
        )

        print(response.text)

Client().get_asset()
