01项目环境搭建_哔哩哔哩_bilibili  本博客借鉴至大佬的视频学习笔记

# 创建项目
django-admin startproject MyShop

# 创建app
E:\desktop\my_drf\MyShop>django-admin startapp goods

E:\desktop\my_drf\MyShop>django-admin startapp order

E:\desktop\my_drf\MyShop>django-admin startapp cart

E:\desktop\my_drf\MyShop>django-admin startapp users

创建apps文件夹放入的上面应用

# 注册应用
'rest_framework',
'corsheaders',
'apps.users',
'apps.goods',
'apps.cart',
'apps.order'

# 配置mysql
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'shop',
        'USER': 'root',
        'PASSWORD': 'pass',
        'HOST': 'localhost',
        'PORT': 3306
    }
}

# 允许所有的用户跨域请求
CORS_ORIGIN_ALLOW_ALL = True

# 中文及时区调整
LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'

 创建shop数据库

mysql> create database shop charset=utf8;
Query OK, 1 row affected, 1 warning (0.01 sec)

 公共表设计:

# 定义继承时，需要setting自定义用户类模型
AUTH_USER_MODEL = 'users.User'

# 创建 common目录下db.py文件
from django.db import models

class BaseModel(models.Model):
    """ 抽象的模型基类，定义公共模型字段 """

    create_time = models.DateTimeField(auto_now_add=True,verbose_name='创建时间')
    update_time = models.DateTimeField(auto_now=True,verbose_name='更新时间')
    is_delete = models.BooleanField(default=False,verbose_name='删除标记')

    class Meta:
        # 声明这个是抽象模型，生成迁移文件时，不会在数据库生成表
        abstract = True
        verbose_name_plural = '公共字段表'
        db_table = 'BaseTabel'

用户表结构设计

from django.db import models
from django.contrib.auth.models import AbstractUser  # django自带的用户认证模型
from common.db import BaseModel
# Create your models here.

class User(AbstractUser,BaseModel):
    """用户表"""
    mobile = models.CharField(verbose_name='手机号',help_text='手机号',max_length=11,default='',blank=True)
    avatar = models.ImageField(verbose_name='用户头像',help_text='用户头像',max_length=30,null=True,blank=True)

    class Meta:
        db_table = 'users'
        verbose_name = '用户表'

class Addr(models.Model):
    """收货地址模型"""
    user = models.ForeignKey('User',verbose_name='所属用户',on_delete=models.CASCADE)
    phone = models.CharField(verbose_name='手机号',help_text='手机号',max_length=11,null=True,blank=True)
    name = models.CharField(verbose_name='联系人',help_text='联系人',max_length=20,null=True,blank=True)
    province = models.CharField(verbose_name='省份',help_text='省份',max_length=20,null=True,blank=True)
    city = models.CharField(verbose_name='城市',help_text='城市',max_length=20,null=True,blank=True)
    country = models.CharField(verbose_name='区县',help_text='区县',max_length=20,null=True,blank=True)
    is_default = models.BooleanField(verbose_name='是否为默认地址',help_text='省份',max_length=30,default=False)

    class Meta:
        db_table = 'addr'
        verbose_name = '收货地址表'

class Area(models.Model):
    """省市区县地址模型"""
    pid = models.ImageField(verbose_name='上级ID',help_text='上级ID',max_length=20,null=True,blank=True)
    name = models.CharField(verbose_name='地区名',help_text='地区名',max_length=20,null=True,blank=True)
    level = models.CharField(verbose_name='区域等级',help_text='区域等级',max_length=20,null=True,blank=True)

    class Meta:
        db_table = 'area'
        verbose_name = '地区表'

class VerifyCode(models.Model):
    """验证码模型"""
    mobile = models.CharField(verbose_name='手机号码',help_text='手机号码',max_length=11,null=True,blank=True)
    code = models.CharField(verbose_name='验证码',help_text='验证码',max_length=6,null=True,blank=True)
    create_time = models.DateTimeField(auto_now_add=True,verbose_name='生成时间',help_text='生成时间')

    class Meta:
        db_table = 'verifycode'
        verbose_name = '手机验证码表'

 执行迁移文件，生成表结构

E:\desktop\my_drf\MyShop>python manage.py makemigrations
Migrations for 'users':
  apps\users\migrations\0001_initial.py
    - Create model User
    - Create model Area
    - Create model VerifyCode
    - Create model Addr

E:\desktop\my_drf\MyShop>python manage.py migrate

 结果展示：

 用户鉴权：使用JWT认证

创建超级管理员用户

E:\desktop\my_drf\MyShop>python manage.py createsuperuser
用户名: pass
电子邮件地址: pass@qq.com
Password:
Password (again):

JWT权限认证配置

# 注册jwt
'rest_framework_simplejwt',

# 配置setting
REST_FRAMEWORK = {
    # DRF配置鉴权方式
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        'rest_framework.authentication.BasicAuthentication',  # Basic 认证
        'rest_framework.authentication.SessionAuthentication',  # Session 认证
    ),
}

# 配置总路由urls

path('api/users/',include('apps.users.urls'))

# user url 配置
from rest_framework_simplejwt.views import TokenVerifyView, TokenRefreshView, TokenObtainPairView

urlpatterns = [
    path('login/', TokenObtainPairView.as_view(), name='login'),  # 登录
    path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),  # token 刷新
    path('token/verify/', TokenVerifyView.as_view(), name='token_verify'),  # token 效验
]

 配置Postman环境变量

Postman运行示图：

 自定义用户登录功能的实现

from rest_framework_simplejwt.views import TokenObtainPairView

# Create your views here.
class LoginView(TokenObtainPairView):
    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)

        try:
            serializer.is_valid(raise_exception=True)
        except TokenError as e:
            raise InvalidToken(e.args[0])
        # 自定义登录成功后返回的数据信息
        result = serializer.validated_data
        result['id'] = serializer.user.id
        result['email'] = serializer.user.email
        result['mobile'] = serializer.user.mobile
        result['username'] = serializer.user.username
        result['token'] = result.pop('access')

        return Response(serializer.validated_data, status=status.HTTP_200_OK)

运行结果：

用户注册功能的实现

import re
from rest_framework import status
from rest_framework.response import Response
from rest_framework_simplejwt.exceptions import TokenError, InvalidToken
from rest_framework_simplejwt.views import TokenObtainPairView
from rest_framework.views import APIView
from .models import User
# Create your views here.
class RegisterView(APIView):
    def post(self,request):
        """注册：接收参数并校验、创建用户 """
        username = request.data.get('username')
        password = request.data.get('password')
        email = request.data.get('email')
        password_confirmation = request.data.get('password_confirmation')
        # 检验
        print(all([username,password,email,password_confirmation]))
        print([username,password,email,password_confirmation])
        if not all([username,password,email,password_confirmation]):
            return Response({'error':'所有参数不能为空'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        # 检验用户是否已存在
        if User.objects.filter(username=username).exists():
            return Response({'error':'用户名已存在'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        # check password
        if password !=password_confirmation:
            return Response({'error':'两次输入的密码不一致'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        if not (6<len(password)<18):
            return Response({'error':'密码长度需要在6-18位之间'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        # check email
        if User.objects.filter(email=email).exists():
            return Response({'error':'该邮箱已被他人注册'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        if not re.match(r'^[a-z0-9][\w.\-]*@[a-z0-9\-]+(\.[a-z]{2,5}){1,2}$',email):
            return Response({'error':'邮箱格式有误'},status=status.HTTP_422_UNPROCESSABLE_ENTITY)
        # 创建用户
        obj = User.objects.create_user(username=username,email=email,password=password)
        res = {
            'username':username,
            'id':obj.id,
            'email':obj.email
        }
        return Response(res,status=status.HTTP_201_CREATED)


# url 配置
path('register/', RegisterView.as_view(), name='register'),  # 注册

多字段用户登录功能支持
