一、短信注册接口

需要手机号+验证码+密码——>{mobile:手机号,code:验证码,password:密码}——>post请求，后端路由127.0.0.1:8080/api/v1/userinfo/user/register

写个视图def register(self,request):
写个序列化类UserRegisterSerializer只用来做反序列化和数据校验，不做序列化
接收三个字段：mobile、code、password，表里没有code，重写code字段可设置最长、最短，都是4就行
全局校验：1、验证code是否正确、不正确直接返回 2、入库前的准备，把code用pop剔除，username设置为手机号，返回attrs 3、保存正常不用写，新增userinfo，密码是加密的重写create方法
register视图获取、保存、返回注册成功

代码展示

serializer.py

class UserRegisterSerializer(serializers.ModelSerializer):
    code = serializers.CharField(max_length=4, min_length=4)

    class Meta:
        model = UserInfo
        fields = ['mobile', 'code', 'password']

    def validate(self, attrs):
        # 1、验证code是否正确
        mobile = attrs.get('mobile')
        code = attrs.get('code')
        old_code = cache.get('sms_code_%s' % mobile)
        if not (old_code == code or code == '1111'):
            raise APIException('铁铁，验证码错误')
        # 2、入库前的准备，code剔除，username设置为手机号
        attrs['username'] = mobile
        attrs.pop('code')
        return attrs
        # 3、保存正常不用写，新增userinfo，密码是加密的——>重写create方法

    def create(self, validated_data):  # 现在里面三个字段：mobile、username、password
        user = UserInfo.objects.create_user(**validated_data)
        return user

user/views

@action(methods=['POST'], detail=False)
def register(self,request):
    ser = UserRegisterSerializer(data=request.data)
    ser.is_valid(raise_exception=True)
    ser.save()
    return APIResponse(msg='铁铁，注册成功')

二、登录前台

多方式登录方法

用户名+密码登录

传用户名和密码，element整个弹窗“用户名或密码不能为空”
登录地址发送$axios.post请求
登录成功将用户名、token、头像存到本地存储中，放cooks里，一般7天过期
销毁模态框 $emit('close')触发Header.vue里的@close
写右上角的登录|注销，取出token和username，退出功能只需要本地删除token即可，$cookies.remove移除

手机号+验证码登录

@blur ="check_mobile" 如果手机号没有就啥也不动没问题，输入正则判断输入手机号不合法清空，is_send=True 正确的话允许发送短信，不是True不可以，点一次就变成False
this.sms_interval = "发送中...启用下方定时任务
发送短信：axios get请求网址：前面一串+send_sms+？mobile='this.mobile'
验证手机号是否注册了，if判断，写了手机号不存在直接清空
验证手机号+验证码都有的情况下登录，登录成功cookies存下来

四、redis介绍

1、介绍CS架构的软件

redis：非关系型数据库【存数据的地方】，内部存储，速度非常快，如果断电了，内存数据就没了

redis是nosql数据库：指非关系型数据库：1、不限于SQL 2、没有SQL（我不写sql）

可以持久化【数据从内存同步到硬盘】，

数据类型丰富【5大数据类型】

字符串
列表
哈希（字典）
集合
有序集合

key_value形式存储【根本没有表的结构，相当于咱们的字典】

2、redis 为什么这么快？

高性能的网络模型：IO多路复用的epoll模型，承载住非常高的并发量
纯内存操作，避免了很多IO
单线程架构，避免了线程之间切换的消耗
- 6.x以前：单线程，单进程
- 6.x以后：多线程架构，数据库操作还是使用单线程，别的线程做数据持久化，其他操作

3、redis应用场景（了解项）

当缓存数据库使用，接口缓存，提高接口响应速度
- 请求进到视图——>去数据查询【多表查询，去硬盘取数据：速度慢】——>转成json格式字符串——>返回给前端
- 请求到视图——>去redis【内存】——>取json格式字符串——>返回给前端
当计数器：单线程，不存在并发安全问题
- 统计网站访问量
- 个人站点浏览量
- 文章阅读量
去重操作：集合
排行榜：有序集合
- 阅读排行榜
- 游戏金币排行榜
布隆过滤器
抽奖
消息队列

五、redis安装

开源软件：使用c语言写的---【编译型语言，在操作系统运行，要编译成可执行文件，由于采用了IO多路复用的epoll模型，所以它不支持windows，只有linux操作系统支持epoll】

微软官方：改了，编译成可执行的安装包，下载一路下一步安装
-版本没有最新

官网：https://redis.io/
-下载完是源代码：c语言源码：https://redis.io/download/#redis-stack-downloads
-最稳定：6.x
-最新7.x

中文网：http://redis.cn/download.html
-上面最新只到5.x

win版本下载地址

最新5.x版本 https://github.com/tporadowski/redis/releases/
最新3.x版本 https://github.com/microsoftarchive/redis/releases
下载完一路下一步即可，具体可参照：https://www.cnblogs.com/liuqingzheng/p/9831331.html

win装完会有redis服务

启动服务，手动停止
客户端链接：redis-cli -h 127.0.0.1 -p 6379
简单命令：
- set name lqz
- get name
- ping 客户端和服务端连接

停掉服务：

去win服务点关闭
客户端关闭：shutdown

mysql服务端、mysql客户端	redis服务端、redis客户端
Navicate	redis-cli
命令窗口cmd	图形化工具：redis-destop-management
python操作	python操作
