luffy——前端注册页面分析_——登录前端——注册前端。。多方式登录前端。。redis介绍和安装

前倾回顾

# 1 用户板块相关接口
    - 验证手机号是否存在
    - 多方式登录接口
    - 发送短信接口(发送登录和发送注册短信使用同一个接口)
    - 短信登录接口
    - 短信注册接口
    
    
# 2 验证手机号是否存在
    -请求地址，编码格式，携带的数据---》后端写接口人定的
    -地址：/api/v1/user/mobile/check_mobile/
    -post请求
    -请求体:{mobile:手机号}
    -自动生成路由---》视图类--》 def mobile(self, request)
    -@action(methods=['post'], detail=False, url_path='check_mobile')
# 3 多方式登录
    -请求地址，编码格式，携带的数据---》后端写接口人定的
    -地址：/api/v1/user/login/mul_login/
    -请求方式：post
    -编码格式：json
    -请求体：{username:用户名/手机号/邮箱,password:}
    
    -自动生成路由：
    router.register('login', UserLoginView, 'login')
    -写了个视图类：
    class UserLoginView(GenericViewSet):
        @action(methods=['POST'], detail=False)
        def mul_login(self,request):
            # ser=MulLoginSerializer(data=request.data)
            ser = self.get_serializer(data=request.data, context={'request': request})
            ser.is_valid(raise_exception=True) # 字段自己[继承ModelSerializer，没有重写username]，局部钩子[没有],全局钩子[重点写的]
            token
            username    ser.context.get('username')
            icon
            return 给前端
   - 序列化类:只做 校验
    class MulLoginSerializer(serializer.Serializer):
        username = serializers.CharField()
        password = serializers.CharField()
        def validate(self, attrs):
            user = self._get_user(attrs)
            token = self._get_token(user)
            self._set_context(token, user)
            return attrs
# 4 发送短信接口  
    -第三方发送短信：腾讯云短信
        -发短信：直接复制---》测试
    -封装：以后任意项目直接把包复制过去，导入就能使用
        -settings.py  # 配置信息---》在项目的配置文件中配置
        -__init__.py  # 注册了一下 想给外部用的函数
        -sms.py # 获取随机验证码   发送短信
        
        
   -发送短信接口：
    get：/api/v1/user/mobile/send_sms/?mobile=ssss
    
    
# 5 短信登录接口
    -{mobile ,code }
    -视图类，跟之前一模一样
    -序列化类中：只有校验用户不一样   签发token，放context都是一样
    
    
    
# 6 注册接口
    -{mobile，code，password}
    
    -注册接口不带密码---》也能注册成功---》发个短信--》让它及时修改密码
    -生成默认密码---》第一次不允许登录
    
    
    -手机号+验证码   如果注册过就登录，如果没注册过，就注册并且登录成功--》作业

 

前端注册页面分析

# 登录，注册，都写成组件----》在任意页面中，都能点击显示登录模态框
# 写好的组件，应该放在那个组件中----》不是【页面组件】(小组件)
    如果我们想写简单---》登录注册做成页面组件--》点击路由跳转即可
    放在Header.vue中，以后任意页面组件都会引入Header---》都会有登录注册的按钮
# 点击登录按钮，把Login.vue 通过定位，占满全屏，透明度设为 0.5 ,纯黑色背景，覆盖在组件上
# 在Login.vue点关闭，要把Login.vue隐藏起来，父子通信之子传父，自定义事件

Header.vue

## 页面中
<span @click="go_login">登录</span>


<Login v-if="login_show" @close_login="close_login"></Login>
## data
login_show: false
### methods
   go_login() {
      this.login_show = true
    },
    close_login() {
      this.login_show = false
    }

Login.vue

redis介绍和安装

# redis 是什么？
    -非关系型数据库:redis,mongodb,es,clickhouse,influxDB
        no sql: not only sql 
    
    -关系型数据库：mysql，oracle,postgrasql,sqlserver,sqlite
        -去IOE  ，国产化
            IBM：服务器     
            Oracle：数据库   达梦
            EMC：存储 
            
    -redis 到底是什么？
        redis是一个key-value存储系统【软件】，用c语言写的，c/s架构的软件，纯内存存储，可以持久化【断电数据可以恢复】
        value:有5钟数据类型
            string：字符串
            hash：字典
            list：列表
            set：集合
            zset：有序集合
# redis为什么这么快？
    - qps ：10w   6w左右
    -1 纯内存操作，避免了io
    -2 使用了io多路复用的网络模型--（epoll）
    -3 数据操作是单线程单进程---【没有锁操作，没有线程间切换】
    
# 安装redis
    -redis开源项目，社区不支持win
        -使用的epoll模式，不能再win上运行的
    -微软团队---》基于人家源码，修改+编译---》安装包--》可以装在win上
    -最新：最新7.x
    # win平台最新只有
    -最新5.x版本 https://github.com/tporadowski/redis/releases/
