深圳外贸网站建设公司seo根据什么具体优化

1 注册功能
补充(开放文件夹内)
2 前端登录注册页面复制
4 前端注册功能

1 注册功能

# 分析前端：携带数据格式 {mobile:,code:,password}后端：-1 视图类---》注册方法-2 序列化类---》校验，保存（表中字段多，传的少---》随机，按某种格式生成---》后期修改）

视图类

class UserRegisterView(GenericViewSet, CreateModelMixin):serializer_class = UserRegisterSerializer# @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()#     return APIResponse(msg='恭喜您注册成功')# 或者改为@action(methods=['POST'], detail=False)def register(self, request, *args, **kwargs):# 如果是这样做的话，内部执行serializer.data---->会走序列化----》# 基于create返回的user做序列化-----》按照fields = ['mobile', 'code', 'password']做序列化# 但是code不是表中的字段，就会报错，这个时候需要在序列化类中将其反序列化# 即：code = serializers.CharField(max_length=4, min_length=4, write_only=True)res = super().create(request, *args, **kwargs)return APIResponse(msg='恭喜注册成功')

序列化类

class UserRegisterSerializer(serializers.ModelSerializer):# code 不是表中字段code = serializers.CharField(max_length=4, min_length=4, write_only=True)class Meta:model = Userfields = ['mobile', 'code', 'password']def validate(self, attrs):# 1 校验验证码是否正确mobile = attrs.get('mobile')code = attrs.get('code')old_code = cache.get('cache_mobile_%s' % mobile)if code == old_code or code == '8888':  # 测试阶段，万能验证码# 2 组装数据 ：username必填，但是没有,code不是表的字段attrs['username'] = mobileattrs.pop('code')# 3 返回return attrsdef create(self, validated_data):  # 密码是加密的，如果重写，密码是明文的  validated_data=mobile，password，usernameuser = User.objects.create_user(**validated_data)return user

补充(开放文件夹内)

#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-后续改密码：user.set_password(new_password)

2 前端登录注册页面测试

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
