为项目添加log记录

1. 工作目录中新建log文件夹，用来存放log日志
   settings.py文件添加日志路径配置

# 日志配置
BASE_LOG_DIR = os.path.join(BASE_DIR, "log")

2. public文件夹下新增log.py文件

# _*_ coding:utf-8 _*_
import time
import logging
from QAPlatform.settings import BASE_LOG_DIR

# 定义日志名称，每天生成一个日志文件
timer = time.strftime("%y-%m-%d", time.localtime(time.time()))
global logname
logname = BASE_LOG_DIR + r"\log" + timer + ".txt"

class Log:
    def __init__(self,level="INFO"):
        print ("start")
        self.filename=logname
        self.level=level
        self.logger=logging.getLogger() #得到logger实体
        self.logger.setLevel(logging.DEBUG)#设置日志最低输出级别默认为WARN
        self.formatter=logging.Formatter("[%(asctime)s - %(filename)s] - %(levelname)s : %(message)s")#设置日志格式

    def __createHandler(self):
        #创建FileHandler,日志输入到文件
        fh=logging.FileHandler(self.filename,'a',encoding='utf-8')
        fh.setLevel(logging.DEBUG)
        fh.setFormatter(self.formatter)
        self.logger.addHandler(fh)

        # 创建FileHandler,日志输入到控制台
        ch = logging.StreamHandler()
        ch.setLevel(logging.DEBUG)
        ch.setFormatter(self.formatter)
        self.logger.addHandler(ch)
        return fh,ch

    def __console(self,message):
        if self.level == "INFO":
            self.logger.info(message)
        if self.level == "DEBUG":
            self.logger.debug(message)
        if self.level == "WARN":
            self.logger.warn(message)
        if self.level == "ERROR":
            self.logger.error(message)

    def __call__(self,fuc):
        def wrapper(*args,**kwargs):
            fh, ch=self.__createHandler()
            for i in range(len(args)):
                self.__console(args[i])
            self.logger.removeHandler(fh)
            self.logger.removeHandler(ch)
            fuc(*args, **kwargs)
        return wrapper


@Log(level="INFO")
def writeLog_info(message):
    print(message)

@Log(level="DEBUG")
def writeLog_debug(message):
    print(message)

@Log(level="WARN")
def writeLog_warn(message):
    print(message)

@Log(level="ERROR")
def writeLog_error(message):
    print(message)

3. view.py文件中的使用，已登录为例：

from public.utils import login_Check
from public.log import *
from rbac.service.init_permission import init_permission

def login(request):
    if request.method == "GET":
        return render(request, "login.html")
    if request.method == "POST":
        username = request.POST.get('form-username')
        password = request.POST.get('form-password')

        user_obj = UserInfo.objects.filter(username=username, password=password).first()
        try:
            if user_obj:
                try:
                    init_permission(request, user_obj)  # 调用init_permission，初始化权限
                    writeLog_info(u"用户%s:权限初始化成功！" % username)
                except Exception as e:
                    writeLog_error(u"用户%s:权限初始化失败：%s" % (username,str(e)))
                try:
                    request.session["user_id"] = user_obj.pk
                    request.session["Username"] = username
                    print("==========session保存：", request.session['Username'])
                    writeLog_info(u"用户%s保存session:%s" % (username,request.session))
                except Exception as e:
                    writeLog_error(u"用户%s保持session失败：%s" % (username, str(e)))
                try:
                    t = 300
                    request.session.set_expiry(t)  # 设置session有效期为60s*5=5分钟
                    writeLog_info(u"设置session有效期：%s分钟" % (int(t/60)))
                except Exception as e:
                    writeLog_error(u"设置session有效期失败：%s" % (str(e)))

                writeLog_info(u"用户%s:登录成功" % username)
                return HttpResponseRedirect("/index/")
        except Exception as e:
            writeLog_error(u"登录失败:%s"%(str(e)))
            return render(request, "login.html", {"error": "Username and Password is error"})
