python项目结束后权限管理配置

本文主要是介绍python项目结束后权限管理配置，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、创建rbac的app

python manage.py startapp rbac
注入;settings.py的INSTALLED_APPS中

二、创建rbac表，在rbac的models.py中添加

from django.db import models
# 权限表
class Permission(models.Model):

    title = models.CharField(verbose_name='标题', max_length=32)
    url = models.CharField(verbose_name='含正则的URL', max_length=128)

    is_menu = models.BooleanField(verbose_name='是否可做菜单',default=False)
    icon = models.CharField(max_length=32,null=True,blank=True)
    def __str__(self):
        return self.title

# 角色
class Role(models.Model):

    title = models.CharField(verbose_name='角色名称', max_length=32)
    permissions = models.ManyToManyField(verbose_name='拥有的所有权限', to='Permission', blank=True)


    def __str__(self):
        return self.title

# 用户表
class UserInfo(models.Model):

    name = models.CharField(verbose_name='用户名', max_length=32)
    password = models.CharField(verbose_name='密码', max_length=200)
    email = models.CharField(verbose_name='邮箱', max_length=32)
    roles = models.ManyToManyField(verbose_name='拥有的所有角色', to='Role', blank=True)

    def __str__(self):
        return self.name

创建数据库结构   python.exe manage.py  makemigrations   && python.exe manage.py  migrate

三、创建权限检查表，在rbac下创建middleware文件，在该目录下创建rbac.py文件

from django.utils.deprecation import MiddlewareMixin
from xyglweb import settings
from django.shortcuts import redirect, render
import re

class RbacMiddleware(MiddlewareMixin):

    def process_request(self,request):
        # 1、获取当前请求的url
        current_url = request.path_info
        #1.5 添加白名单

        for reg in settings.VAILD_URL:
            if re.match(reg,current_url):
                return None
        #2、获取当前用户的session中的所有权限
        permission_list = request.session.get(settings.PERMISSION_SESSION_KEY)
        role_list  = request.session.get(settings.ROLE_SESSION_KEY)
        if not permission_list:
            return redirect('/portal/')

        #3、进行权限校验
        print(current_url)
        print(role_list,'RRRRRRRRRRRRRRR')
        # print(permission_list)
        flag = False
        for item in permission_list:
            reg = "^%s$" % item.get('permissions__url')
            if re.match(reg,current_url):
                flag = True
                break
        if not flag:
            return render(request,'error/403.html')

注入;settings.py的MIDDLEWARE中 “'rbac.middleware.rbac.RbacMiddleware',”

 四、在settings中配置变量

PERMISSION_SESSION_KEY = "permission_list"
MENU_SESSION_KEY = "menu_list"
ROLE_SESSION_KEY = "role_list"
#1.5 添加白名单
VAILD_URL = [
            '^/admin/*',
            '^/portal/$',
            '^/$',
            '/clean_cookie/',
            # '/ywworkportal/','/addywwork/','/upload/','/yunweiticx/','/addxgg1port/','/delgg1/','/article_detail/','/editblog/','/delblog/','/addxgg2port/','/delgg2/',
            # '/addxgg3port/','/delgg3/','/addxgg4port/','/delgg4/',
        ]

五、在rbac的admin.py中注册

from django.contrib import admin

# Register your models here.
from rbac import models

class PermissionAdmin(admin.ModelAdmin):
    list_display = ['title','url','is_menu','icon']
    # list_editable = ['url']
class RoleAdmin(admin.ModelAdmin):
    list_display = ['title']

class UserInfoAdmin(admin.ModelAdmin):
    list_display = ['name','email']

admin.site.register(models.Permission,PermissionAdmin)
admin.site.register(models.Role,RoleAdmin)
admin.site.register(models.UserInfo,UserInfoAdmin)
