昨日回顾
# 前端登陆注册页面
# 腾讯云短信发送---》第三方的服务,如何去集成
-API接口:操作起来麻烦一些
-SDK:分语言
-使用了腾讯云的sdk-->v3版本
-v2版本不支持python3.8及以上---》源码中的json模块改动了
-案例--->脚本运行---》运行成功,集成到项目---》把它做成一个包,以后换 任何项目,直接导入包使用即可
-settings.py sms.py __init__.py
-配置文件 get_code,send_sms(code,phone) 包导入会执行它,以后使用包名.get_code
-code要保存,方便取---》需要传入
# 发送短信接口
-get请求---> ?phone=123444222--->从request.query_params中取出手机号,调用发送短信的函数,直接发送短信
-验证码保存?---》bbs项目,图像验证码---》存到session中
-现在不用session,cookie咱们也操作不了,如果真的想操作cookie,只能通过接口 返回,前端 自己操作--->安全非常低
-缓存:是一个存数据的地方,可以存,可以取(缓存可以缓存到的位置有很多,内存,文件,redis,mysql)
-默认缓存到内存中,后期要放到redis中
-django是一个大而全的框架,内置了缓存功能,我们只需要直接导入用即可
from django.core.cache import cache
cache.set('sms_cache_%s'%phone,code) # 设置值,key value形式,key应该唯一,使用手机号
# cache.get() # 取值,根据key取
今日内容
1 短信登陆接口
# 原型图写接口---》页面--》该接口需要两个参数
{mobile:123442,code:8888}
# 你现在是软件开发者,你是上帝,在造人,登陆功能,不要站在使用者的角度
-用户名输入1,密码输入1,就登陆到超级用户上,能实现吗?
#
1.1 视图类
class LoginView(GenericViewSet):
serializer_class = MulLoginSerializer
queryset = User
# 两个登陆方式都写在这里面(多方式,一个是验证码登陆)
# login不是保存,但是用post,咱们的想法是把验证逻辑写到序列化类中
@action(methods=["post"], detail=False)
def mul_login(self, request):
return self._common_login(request)
# 127.0.0.1:8000/api/v1/user/login/sms_login
@action(methods=["post"], detail=False)
def sms_login(self, request):
# 默认情况下使用的序列化类使用的是MulLoginSerializer---》多方式登陆的逻辑-->不符合短信登陆逻辑
# 再新写一个序列化类,给短信登陆用
return self._common_login(request)
def get_serializer_class(self):
# 方式一:
# if 'mul_login' in self.request.path:
# return self.serializer_class
# else:
# return SmsLoginSerializer
# 方式二
if self.action=='mul_login':
return self.serializer_class
else:
return SmsLoginSerializer
def _common_login(self,request):
try:
# 序列化类在变
ser = self.get_serializer(data=request.data, context={'request': request})
ser.is_valid(raise_exception=True) # 如果校验失败,直接抛异常,不需要加if判断了
token = ser.context.get('token')
username = ser.context.get('username')
icon = ser.context.get('icon')
return APIResponse(token=token, username=username, icon=icon) # {code:100,msg:成功,token:dsadsf,username:lqz}
except Exception as e:
raise APIException(str(e))
1.2 序列化类
# 只用来做反序列化,短信登陆
class SmsLoginSerializer(serializers.ModelSerializer):
code = serializers.CharField(max_length=4, min_length=4) # 字段自己的规则
mobile = serializers.CharField(max_length=11, min_length=11) # 一定要重写,不重写,字段自己的校验过不去,就到不了全局钩子
class Meta:
model = User
fields = ['mobile', 'code'] # code不在表中,它是验证码,要重新
def validate(self, attrs):
# 1 验证手机号是否和合法 验证code是否合法---》去缓存中取出来判断
self._check_code(attrs)
# 2 根据手机号获取用户---》需要密码吗?不需要
user = self._get_user(attrs)
# 3 签发token
token = self._get_token(user)
# 4 把token,username,icon放到context中
request = self.context['request']
self.context['token'] = token
self.context['username'] = user.username
self.context['icon'] = 'http://%s/media/%s' % (request.META['HTTP_HOST'], str(user.icon))
return attrs
def _check_code(self, attrs):
mobile = attrs.get('mobile')
new_code = attrs.get('code')
if mobile:
# 验证验证码是否正确
old_code = cache.get('sms_cache_%s' % mobile)
if new_code != old_code:
raise ValidationError('验证码错误')
else:
raise ValidationError('手机号没有带')
def _get_user(self, attrs):
mobile = attrs.get('mobile')
# return User.objects.get(mobile=mobile)
user = User.objects.filter(mobile=mobile).first()
if user:
return user
else:
raise ValidationError("该用户不存在")
def _get_token(self, user):
# jwt模块中提供的
from rest_framework_jwt.serializers import jwt_payload_handler, jwt_encode_handler
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
return token
2 短信注册接口
# 前端带入的参数---》post--》{mobile:1234444,code:8888,password:lqz1234}-->创建一个新用户
2.1 路由
# 127.0.0.1:8000/api/v1/user/register --- >post请求
router.register('register',RegisterView , 'register')
2.2 视图类
from rest_framework.mixins import CreateModelMixin
class RegisterView(GenericViewSet,CreateModelMixin):
serializer_class = RegisterSerializer
queryset = User.objects.all()
def create(self, request, *args, **kwargs):
# 方式一:
super().create(request, *args, **kwargs) # 小问题,code不是表的字段,需要用write_only
# 方式二:
# serializer = self.get_serializer(data=request.data)
# serializer.is_valid(raise_exception=True)
# # self.perform_create(serializer)
# serializer.save()
return APIResponse(msg='注册成功')
2.3 序列化类
# 主要用来做反序列化,数据校验----》其实序列化是用不到的,但是create源码中只要写了serializer.data,就会用序列化
class RegisterSerializer(serializers.ModelSerializer):
code = serializers.CharField(max_length=4, min_length=4,write_only=True)
class Meta:
model = User
fields = ['mobile', 'code', 'password']
extra_kwargs = {
'password': {'write_only': True},
}
def validate(self, attrs):
# 1 校验手机号和验证码
self._check_code(attrs)
# 2 就可以新增了---》User中字段很多,现在只带了俩字段,
# username必填随机生成,code不存表,剔除,
# 存user表,不能使用默认的create,一定要重写create方法
self._per_save(attrs)
return attrs
# 校验手机号
def validate_mobile(self, value): # 局部钩子
if not re.match(r'^1[3-9][0-9]{9}$', value):
raise ValidationError('手机号不合法')
return value
# 入库前准备
def _per_save(self, attrs):
# 剔除code,
attrs.pop('code')
# 新增username-->用手机号作为用户名
attrs['username'] = attrs.get('mobile')
# 写成公共函数,传入手机号,就校验验证码
# 经常公司中为了省短信,回留万能验证码,8888
def _check_code(self, attrs):
# 校验code
new_code = attrs.get('code')
mobile = attrs.get('mobile')
old_code = cache.get('sms_cache_%s' % mobile)
if new_code != old_code:
raise ValidationError("验证码错误")
def create(self, validated_data):
# 如果补充些,密码不是密文
user = User.objects.create_user(**validated_data)
return user
3 登陆注册前端
# 127.0.0.1:8080 和localhost:8080 和 192.168.31.226:8080
# 前端可以存数据的地方
-存到cookie中,js操作,在vue中可以借助vue-cookies第三方插件
-cnpm install vue-cookies -S
-main.js中
import cookies from 'vue-cookies'
Vue.prototype.$cookies = cookies;
-以后用
this.$cookies.set()
this.$cookies.get()
-localStorage,永久存储
localStorage.setItem('key', 'value');
localStorage.key = "value"
localStorage["key"] = "value"
-sessionStorage,临时存储,关闭浏览器就没了
sessionStorage.setItem("age",'19')

3.3 后端配置cookie和token过期时间

# 过期时间1天
'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),
}
4 redis介绍和安装
#1 redis 是一个非关系型数据库(区别于mysql关系型数据库,关联关系,外键,表),nosql数据库(not only sql:不仅仅是SQL),数据完全内存存储(速度非常快)
#2 redis就是一个存数据的地方
#3 redis是 key --value 存储形式---》value类型有5大数据类型---》字符串,列表,hash(字典),集合,有序集合
# java:hashMap 存key-value形式
# go:maps 存key-value形式
#4 redis的好处
(1) 速度快,因为数据存在内存中,类似于字典,字典的优势就是查找和操作的时间复杂度都是O(1)
(2) 支持丰富数据类型,支持string,list,set,sorted set,hash
(3) 支持事务,操作都是原子性,所谓的原子性就是对数据的更改要么全部执行,要么全部不执行
(4) 丰富的特性:可用于缓存,消息,按key设置过期时间,过期后将会自动删除
#5 redis 最适合的场景---》主要做缓存---》它又叫缓存数据库
(1)会话缓存(Session Cache)---》存session---》速度快
(2)接口,页面缓存---》把接口数据,存在redis中
(3)队列--->celery使用
(4)排行榜/计数器--->个人页面访问量
(5)发布/订阅
# 6 安装---》c语言写的开源软件---》官方提供源码---》如果是在mac或linux上需要 编译,安装
-redis最新稳定版版本6.x
-win:作者不支持windwos,本质原因:redis很快,使用了io多路复用中的epoll的网络模型,这个模型不支持win,所以不支持(看到高性能的服务器基本上都是基于io多路复用中的epoll的网络模型,nginx),微软基于redis源码,自己做了个redis安装包,但是这个安装包最新只到3.x,又有第三方组织做到最新5.x的安装包
安装包---》编译完成的可执行文件---》下一步安装
linux--》make成可执行文件---》make install 安装
-linux,mac平台安装
# 7 win下载地址
// 最新5.x版本 https://github.com/tporadowski/redis/releases/
// 最新3.x版本 https://github.com/microsoftarchive/redis/releases
一路下一步安装
# mysql 有个图形化客户端-Navicat很好用
# redis 也有很多,推荐你用rdb,https://github.com/uglide/RedisDesktopManager/releases 收费,99元永久,白嫖
# redis纯内存操作,有可能把内存占满了,这个配置是最多使用多少内存
# redis服务的启动与关闭
方式一:win上,就在服务中了,把服务开启即可,在服务中启动关闭
方式二:命令启动,等同于mysqld
redis-server redis.windows-service.conf
redis-server 配置文件
# 客户端连接
-命令行:redis-cli -p 端口 -h 地址
-客户端 :rdb连接
