1 异步发送短信

# 原来的发送短信,是同步
	-前端输入手机号---》点击发送短信---》前端发送ajax请求----》到咱们后端接口---》取出手机号----》调用 腾讯发送短信---》腾讯去发短信---》发完后----》回复给我们后端发送成功---》我们后端收到发送成功---》给我们前端返回发送成功
    
# 把腾讯发送短信的过程,变成异步
-前端输入手机号---》点击发送短信---》前端发送ajax请求----》到咱们后端接口---》取出手机号----》开启线程,去调用腾讯短信发送(异步)---》我们后端继续往后走----》直接返回给前端,告诉前端短信已发送
-另一条发短信线程线程会去发送短信,至于是否成功,我们不管了


1.1 视图类

    @action(methods=['GET'], detail=False)
    def send_sms(self, request, *args, **kwargs):
        mobile = request.query_params.get('mobile', None)
        code = get_code()  # 把code存起来,放到缓存中,目前在内存,后期换别的
        cache.set('send_sms_code_%s' % mobile, code)
        if mobile:
            # 开启一个线程,执行发送短信
            t = Thread(target=send_sms_by_mobile, args=[mobile, code])
            t.start()
            return APIResponse(msg='短信已发送')
        raise APIException('手机号没有携带')

1.2 序列化类加入万能验证码

    def _get_user(self, attrs):
        # attrs 中又手机号和验证码
        mobile = attrs.get('mobile')
        code = attrs.get('code')
        # 验证验证码是否正确
        old_code = cache.get('send_sms_code_%s' % mobile)
        # 如果是 debug模式,有个万能验证码,这样就不用真正发送短信了
        if code == old_code or (settings.DEBUG and code == '8888'):
            # 验证码正确,查user
            user = User.objects.filter(mobile=mobile).first()
            if user:
                return user
            else:
                raise APIException('手机号没注册')
        else:
            raise APIException('验证码错误')

2 注册功能

# 前端传入的数据
	{手机号,验证码,密码}
# 后端要验证数据---》序列化类

#遇到的错误
	1 注册使用哪个序列化了:get_serializer_class
    2 配置文件中debug必须是True,因为咱们有万能验证码---》正常流程这个不需要
    3 把code,弹出来,加入用户名,你可以随机生成用户名
    4 重写create(可以不重写,把密码设为加密的密码),create_user
    5 如果你继承了CreateModelMixin,一定要注意,它会走序列化,所以code字段是只写的

3.1 视图类

class UserView(GenericViewSet, CreateModelMixin):
    serializer_class = LoginUserSerializer
    def get_serializer_class(self):
        if self.action == 'sms_login':
            return LoginUserSMSSerializer
        elif self.action == 'register' or self.action == 'create':
            return UserRegisterSerializer
        else:
            # return super().get_serializer_class()
            return self.serializer_class

    # 自己写的  访问:127.0.0.1:8000/api/v1/user/userinfo/register/   --->post请求即可
    @action(methods=['POST'], detail=False)
    def register(self, request, *args, **kwargs):
        ser = self.get_serializer(data=request.data)
        ser.is_valid(raise_exception=True)
        ser.save()
        # super().create(request, *args, **kwargs)  # 只要这样写,又会走序列化
        return APIResponse(msg='注册成功')

    # 不自己写了,只要继承CreateModelMixin,访问:127.0.0.1:8000/api/v1/user/userinfo   --->post请求即可

    # 这个我们不用写,它有  只要post请求过来,就会执行create
    # def create(self, request, *args, **kwargs):
    #     serializer = self.get_serializer(data=request.data) # 第一个错误  UserRegisterSerializer
    #     serializer.is_valid(raise_exception=True) #执行三个校验:字段自己,局部钩子,全局
    #     self.perform_create(serializer)
    #     # 序列化要调用它,只要调用serializer.data ,就会走序列化,只要走序列化,会把create返回的user对象 来使用UserRegisterSerializer类做序列化
    #     return APIResponse(msg='注册成功') #不走序列化了,序列类中得write_only 也就不用了

3.2 序列化类

# 注册:1 校验数据  2 保存  3 序列化用不要?存疑
class UserRegisterSerializer(serializers.ModelSerializer):
    code = serializers.CharField(max_length=4, min_length=4,write_only=True)

    class Meta:
        model = User
        fields = ['mobile', 'password', 'code']  # code 不是数据库的字段,需要重写

    # 如果要限制密码强度,需要写个局部钩子
    def _check_code(self, attrs):
        mobile = attrs.get('mobile')
        code = attrs.get('code')
        old_code = cache.get('send_sms_code_%s' % mobile)
        if not (code == old_code or (settings.DEBUG and code == '8888')):  # 第二个错误:debug忘了设为True
            raise APIException("验证码错误")

    def _pre_save(self, attrs):  # {mobile:122222,code:8888,password:123}
        attrs.pop('code')
        attrs['username'] = attrs.get('mobile')  # 默认用户名就是手机号  可以随机生成用户名  随机生成有意义的名字( Faker)

    def validate(self, attrs):
        # 写逻辑
        # 1 校验验证码是否正确
        self._check_code(attrs)
        # 2 入口前准备 ---》code不是数据库字段,不能入库,username是数据库字段必填,这里没有,写成默认
        self._pre_save(attrs)
        return attrs

    def create(self, validated_data):  # {mobile:122222,password:123,username:名字}
        # 为什么要重写create? 因为密码人家是加密的,如果不写用的是
        # User.objects.create(**validated_data)  # 密码是铭文,必须重写
        user = User.objects.create_user(**validated_data)  # 保存成功,密码就是加密的
        return user

补充

#1  为什么要写这个media才能访问
	-django 默认是不允许前端直接访问项目某个文件夹的
    -有个static文件夹例外,需要额外配置
    -如果想让用户访问,必须配置路由,使用serve函数放开
    	path('media/<path:path>', serve, {'document_root': settings.MEDIA_ROOT})
    	-浏览器中访问 meida/icon/1.png--->能把settings.MEDIA_ROOT对应的文件夹下的icon/1.png返回给前端
        path('lqz/<path:path>', serve, {'document_root':os.path.join(BASE_DIR, 'lqz')})
        浏览器中访问 lqz/a.txt----->能把项目根路径下lqz对应的文件夹下的a.txt返回给前端
        
        
 # 2 配置文件中 debug作用
	-开发阶段,都是debug为True,信息显示更丰富
    	-你访问的路由如果不存在,会把所有能访问到的路由都显示出来
        -程序出了异常,错误信息直接显示在浏览器上
        -自动重启,只要改了代码,会自动重启
    -上线阶段,肯定要改成False
    
    
#3  ALLOWED_HOSTS 的作用
	-只有debug 为Flase时,这个必须填
    -限制后端项目(django项目 )能够部署在哪个ip的机器上,写个 *  表示所有地址都可以
    
    
#4 咱们的项目中,为了知道是在调试模式还是在上线模式,所以才用的debug这个字段
	-判断,如果是开发阶段,可以有个万能验证码
    
    
    
    
# 5 短信登录或注册接口
	-app 只需要输入手机号和验证码,如果账号不存在,直接注册成功,并且登录成功,如果账号存在,就是登录
	-前端传入:{mobiel,code}--->验证验证码是否正确---》拿着mobile去数据库查询,如果能查到,说明它注册过了,直接签发token返回----》如果查不到,没有注册过---》走注册逻辑完成注册---》再签发token,返回给前端
    
    -这个接口,随机生成一个6位密码,以短信形式通知用户
    -这个接口,密码为空,下次他用账号密码登录,不允许登录

3 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)
# 点击登录按钮,把Login.vue 通过定位,占满全屏,透明度设为 0.5 ,纯黑色悲剧,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

3.1 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
    }

3.2 Login.vue

<template>
  <div class="login">
    <span @click="close">X</span>

  </div>
</template>

<script>
export default {
  name: "Login",
  methods: {
    close() {
      this.$emit('close_login')
    }
  }

}
</script>

<style scoped>
.login {
  width: 100vw;
  height: 100vh;
  position: fixed;
  top: 0;
  left: 0;
  z-index: 10;
  background-color: rgba(0, 0, 0, 0.5);
}
