一、短信注册接口

user/views.py

class UserView(ViewSet):
    @action(methods=['POST'], detail=False)
    def register(self, request):
        info = UserRegisterSerializer(data=request.data)
        info.is_valid(raise_exception=True)
        info.save()
        return APIResponse(msg='您已注册成功')

user/serializer.py

class UserRegisterSerializer(serializers.ModelSerializer):  # 用于做数据校验和反序列化
    code = serializers.CharField(max_length=4, min_length=4)

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

    def validate(self, attrs):
        mobile = attrs.get('mobile')
        code = attrs.get('code')
        old_code = cache.get('sms_code_%s' % mobile)
        if not (old_code == code or code == '6666'):
            raise APIException('验证码错误')
        attrs['username'] = mobile
        attrs.pop('code')
        return attrs

    def create(self, validated_data):
        user = UserInfo.objects.create_user(**validated_data)
        return user

接口测试

二、登录功能前端

login.vue(多方式登录+短信验证登录)

<template>

          <span :class="{active: login_method === 'is_sms'}"
                @click="change_login_method('is_sms')">短信登录</span>

四、Redis介绍使用

4.1 什么是Redis

Redis是用C语言开发的一个开源的高性能键值对(key-value)数据库。它通过提供多种键值数据类型来适应不同场景下的存储需求，目前为止Redis支持的键值数据类型有：字符串类型 散列类型 列表类型 集合类型，端口默认为6379。

4.2 Redis的特性

1. 高性能：支持超过 100K+ 每秒的读写频率。
2. 支持多种数据类型：除了key-value类型的数据，同时还提供String，List，Set，hash，以及Ordered Set等数据结构的存储。
3. 原子性：Redis的所有操作都是原子性的，同时Redis还支持对几个操作全并后的原子性执行。
4. 数据持久化：可以将内存中的数据保存在磁盘中，在服务器宕机或者重启时，可以重新读取使用。
5. 单线程：避免了不必要的上下文切换以及加锁导致的一系列性能问题。
6. 功能丰富：Redis还支持 publish/subscribe, 通知, key 过期等等特性。

4.3 Redis的应用场景

1. 热点数据缓存
	redis访问速度快，所以对于那些经常查询且不常修改的数据首选使用redis缓存，像新闻内容、商品内容等。
2. 计数器
	对于视频播放，文章阅读，排行榜等数据计数的情况，并发量较大且对实时性要求比较高，Redis可以极大减轻服务器的压力。
3. 消息队列
	像秒杀，抢购这种活动，可以用于流量削峰，异步处理实时性低的业务（但效果比RabbitMQ，kafka这种专门的消息队列中间件要差点）。
4. 分布式session
	分布式集群架构中的session分离。

4.4 Redis单线程

1. 命令基于内存操作，一条命令在内存的操作也就是几十纳秒
2. 命令是单线程操作没有上下文切换开销
3. 基于I/O多路复用机制提升redis的I/O利用率
4. 高效的数据存储结构：全局hash表以及跳表、压缩表、链表等数据结构。

五、python操作Redis

# 前提，已经安装好了Redis

# 官方网：https://redis.io/
    下载完是源代码：c语言源码 ：https://redis.io/download/
    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

# pycharm安装redis
	pip install redis
    
# 创建一个测试脚本，代码如下：
    from redis import Redis

    connent = Redis(host="localhost", port=6379)
    # connent.set('name', 'tony')
    print(connent.get('name'))
    connent.close()

六、Redis连接池

pool.py

import redis

pool = redis.ConnectionPool(max_connections=200, host='127.0.0.1', port=6379)

redis_pool_test.py

from redis import Redis
from threading import Thread

# 直接连接
# 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(10)


# 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) # 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(10)
