短信注册接口
手机号，验证码，密码--->{mobile:191****1000,code:8888,password:12345}--->post请求
后端路由：127.0.0.1:8080/api/v1/userinfo/user/register
视图类
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 ResponseApi(msg='注册成功')
序列化类
class UserRegisterSerializer(serializers.ModelSerializer):
code = serializers.CharField(max_length=4, min_length=4)
class Meta:
model = UserInfo
fields = ['mobile', 'code', 'password'] # mobile就是唯一的，校验数据库是否唯一，映射过来就有了
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 == '8888'):
raise APIException('验证码错误')
# 2 入库前的准备: 需要把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): # validated_data = mobile,username,password
user = UserInfo.objects.create_user(**validated_data) # 打散存到数据库
return user

redis介绍
c s架构软件
redis：非关系型数据库【存数据的地方】nosql数据库，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】
key-value形式存储【根本没有表的结构，相当于python中的字典】
nosql：指非关系型数据库：1.不限于SQL 2.没有SQL
redis面试题
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，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，别的线程做数据持久化，其他操作
redis 应用场景(了解)
1.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
请求进到视图--->去redis[内存]---->取json格式字符串--->返回给前端
2.做计数器: 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
3.去重操作: 集合
4.排行榜:有序集合
阅读排行榜
游戏金币排行榜
5.布隆过滤器
6.抽奖
7.消息队列
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: 基于开源改了
编译成可执行的安装包，但版本没有最新 下载一路下一步安装
下载完是源代码：C语言源码
地址：https://redis.io/download/#redis-stack-downloads
最稳定：6.x
最新版：7.x
上面最新的只到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
具体可参照博客：https://www.cnblogs.com/liuqingzheng/p/9831331.html
- win装完会有redis服务
启动服务: 下载完会自动启动由于占内存--->调至成手动
客户端链接命令
redis-cli -h 127.0.0.1 -p 6379
简单命令
set name lqz # 设置name值
get name # 获取name对应的值
ping # 查看是否与服务端链接
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
图形化工具: navicate
命令窗口cmd
python操作
redis 服务端
redis 客户端
图形化工具: redis-destop-management
命令窗口cmd
python操作
"""
python操作redis
redis是第三方需要先安装
一、安装redis
pip3 install redis
二、使用
from redis import Redis
conn=Redis( host="localhost",port=6379)
# conn.set('name','xxx')
print(conn.get('name'))
conn.close()
redis连接池
直接使用
def get_name_from_redis():
conn = Redis(host="localhost", port=6379)
print(conn.get('name'))
conn.close()
for i in range(100):
t=Thread(target=get_name_from_redis)
t.start()
import time
time.sleep(1)
使用连接池链接
POOL.py
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
import redis
pool = redis.ConnectionPool(max_connections=3, host='127.0.0.1', port=6379)
redis_pool_demo.py
import redis
from threading import Thread
from POOL import pool
def redis_get_name():
conn = redis.Redis(connection_pool=pool) # 每执行一次会从池中取一个链接，如果没有则等待
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(1)
