短信注册接口

注册需要的数据：手机号、验证码、密码(用户名自动生成)
前端传来的数据格式：{"mobile":"xxx", "code": "xxx", "password": "xxx"}
后端路由： http://127.0.0.1:8000/api/v1/user/userinfo/register/

views.py

class UserView(ViewSet):   
   @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='注册成功')

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):
        # 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 == '8888'):
            raise APIException(detail='验证码错误')
        # 入库前的准备：剔除code，将username设置为手机号
        attrs['username'] = mobile
        attrs.pop('code')
        return attrs

    # 保存正常来说不用写，但我们要使用create_user加密密码，需要重写create方法
    def create(self, validated_data):
        user = UserInfo.objects.create_user(**validated_data)
        return user

redis介绍

# redis是一个 C/S 架构的软件
    redis：非关系型数据库，(nosql)，内存存储，速度非常快，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】，数据以key-value的形式存储【没有表结构，相当于python中的字典】
    nosql：泛指非关系型数据库，可以理解为：1、不止sql  2、没有sql(不写sql语句)

# redis 为什么这么快
    1. 高性能的网络模型：IO多路复用的epoll模型，能承载住非常高的并发量
    2. 纯内存操作，避免了很多IO
    3. 单线程架构，避免了线程间切换的消耗
            6.x之前：单线程、单进程
            6.x以后：多线程架构，数据操作还是使用单线程，其他操作如数据持久化等交给别的线程 
# redis的应用场景
    1. 当缓存数据库使用，请求打到从库(redis)上，减少主库(mysql)的压力。提高接口的响应速度
            请求进到视图-->去数据库查询[多表查询，去硬盘读取数据]，速度慢--->转成json格式
            请求进到视图-->去redis查询[内存查询]速度快--->直接取出json格式字符串 
    2. 做计数器：单线程，不存在并发安全问题
            统计网站访问量、文章阅读量。。。
    3. 去重操作：集合
    4. 排行榜：有序集合
            游戏段位排行榜、阅读排行榜
    5. 布隆过滤器
    6. 抽奖
    7. 消息队列

redis安装

redis是使用c语言写的开源软件
# c语言--->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，他不支持windows，只有linux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
        
    -停掉服务：
    	-去win服务点关闭
        -客户端关闭：shutdown
    
# redis 服务器端
# redis 客户端
    -redis-cli
    -图形化工具：redis-destop-management
    -python操作

python操作redis

pip install install

from redis import Redis

conn = Redis(host='127.0.0.1', port=6379)
conn.set('name', 'jixing')
print(conn.get('name'))
conn.close()

redis连接池

from redis import Redis
from threading import Thread

# 直接链接
# def get_name_from_redis():
#     conn = Redis(host="localhost", port=6379)
#     print(conn.get('name'))
#     conn.close()

### 使用连接池链接
import redis
from POOL import pool
def get_name_from_redis():
    # 创建一个连接池，保证它是单例，全局只有一个pool对象：使用模块导入方式实现单例

    conn = redis.Redis(connection_pool=pool) #m每执行一次会从池中取一个链接，如果没有，等待
    res=conn.get('name')
    print(res)
    conn.close()


for i in range(100):
    t=Thread(target=get_name_from_redis)
    t.start()


import time
time.sleep(10)
