CMDB 知識點

一、ITIL即IT基礎架構庫(Information Technology Infrastructure Library, ITIL，信息技術基礎架構庫)由英國政府部門CCTA(Central Computing and Telecommunications Agency)在20世紀80年代末制訂，現由英國商務部OGC(Office of Government Commerce)負責管理，主要適用於IT服務管理（ITSM）。ITIL爲企業的IT服務管理實踐提供了一個客觀、嚴謹、可量化的標準和規範。

二、Django用戶自定義認證

1、創建models.py

from django.db import models

import hashlib

#自己的後臺數據庫表.account

class Account(models.Model):

    username = models.CharField(u"用戶名",blank=True,max_length=32)

    password = models.CharField(u"密碼",blank=True,max_length=50)

    domain = models.CharField(u"可操作域名",blank=True,max_length=256,help_text='填寫多個域名，以,號分隔')

    is_active = models.IntegerField(u"is_active",blank=True)

    phone = models.CharField(u"電話",max_length=50)

    mail = models.CharField(u"郵箱",max_length=50)

 

    def __unicode__(self):

        return self.username

 

    def is_authenticated(self):

        return True

 

    def hashed_password(self, password=None):

        if not password:

            return self.password

        else:

            return hashlib.md5(password).hexdigest()

    def check_password(self, password):

        if self.hashed_password(password) == self.password:

        #if password == self.password:

            return True

        return False

    class Meta:

        db_table = "account"

2、auth.py

rom django.contrib.auth.models import User

from myauth.models import Account

class MyCustomBackend:

 

    def authenticate(self, username=None, password=None):

        try:

            user = Account.objects.get(username=username)

        except Account.DoesNotExist:

            return None

        else:

            if user.check_password(password):

                try:

                    django_user = User.objects.get(username=user.username)

                except User.DoesNotExist:

                    #當在django中找不到此用戶，便創建這個用戶

                    django_user = User(username=user.username,password=user.password)

                    django_user.is_staff = True

                    django_user.save()

                return django_user

            else:

                return None

    def get_user(self, user_id):

        try:

            return User.objects.get(pk=user_id)

        except User.DoesNotExist:

            return None

3、把自己創建的表也加入到進去，admin.py

from myauth.models import Account

from django.contrib import admin

 

admin.site.register(Account)

4、在settings.py中添加認證：

AUTHENTICATION_BACKENDS = (

    'myauth.auth.MyCustomBackend' ,

)
