注册功能分析
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
视图类
class UserLoginView(GenericViewSet): serializer_class = UserLoginSerializer # queryset没有可以不写 #多方式登录 @action(methods=['POST'], detail=False) def mul_login(self, request, *args, **kwargs): return self._login(request, *args, **kwargs) # 短信登录 @action(methods=['POST'], detail=False) def sms_login(self, request, *args, **kwargs): return self._login(request, *args, **kwargs) #如果没有就注册,如果有就登录 @action(methods=['POST'], detail=False) def mobile_register(self,request,*args,**kwargs): return self._login(request,*args,**kwargs) #不同路由不同序列化 def get_serializer_class(self): if self.action == 'sms_login': return SMSLoginSerializer elif self.action == 'mul_login': return UserLoginSerializer elif self.action == 'mobile_register': return MobileRegisterSerializer else: return super().get_serializer_class() #登录接口 def _login(self, request, *args, **kwargs): ser = self.get_serializer(data=request.data) ser.is_valid(raise_exception=True) username = ser.context.get('username') token = ser.context.get('token') icon = ser.context.get('icon') # icon 必须是字符串形式,不能是对象相似 # {code:100,msg:成功,token:asdfasf,icon:asdfasdf,username:asdfasd} return APIResponse(username=username, token=token, iocn=icon) # {code:100,msg:成功,token:asdfasf,user:{id:1,username:xxx,icon:ssss}} # return APIResponse(token=token, user=ser.data) # 如果执行ser.data,就会走序列化 # def password_change(self,request,*args, **kwargs): # #从密码修改表中找数据,如果旧密码和新密码一致,就不能修改 # #找到旧密码 # mobile = request.data.get('mobile') # password = request.data.get('password') # 继承CreateModelMixin的create class RegisterView(GenericViewSet, CreateModelMixin): serializer_class = UserRegisterSerializer @action(methods=['POST'], detail=False) def user_register(self, request, *args, **kwargs): # 内部执行了它:serializer.data---》走序列化---》基于create返回的user做序列化---》按照'mobile', 'code', 'password' 做序列化---》code不是表中字段,就报错了 res = super().create(request, *args, **kwargs) return APIResponse(msg='注册成功') # ser = self.get_serializer(data=request.data) # print(111) # ser.is_valid(raise_exception=True) # ser.save() # return APIResponse(msg='恭喜您注册成功')
序列化类
# 用户名密码注册序列化 class UserRegisterSerializer(serializers.ModelSerializer): code = serializers.CharField(max_length=6, write_only=True) class Meta: model = User fields = ['mobile', 'password', 'code'] def validate(self, attrs): mobile = attrs.get('mobile') code = attrs.get('code') old_code = cache.get('cache_mobile_%s' % mobile) if old_code == code or (settings.DEBUG and code == '8888'): attrs['username'] = mobile attrs.pop('code') else: raise ValidationError('验证码错误') return attrs # 重写create def create(self, validated_data): user = User.objects.create_user(**validated_data) return user # 短信注册序列化 class MobileRegisterSerializer(serializers.ModelSerializer, LoginSerializer): code = serializers.CharField(max_length=6, write_only=True) # 数据库中没有数据,所以反序列化 class Meta: model = User fields = ['mobile', 'code'] def _get_user(self, attrs): print(attrs) mobile = attrs.get('mobile') print(mobile) code = attrs.get('code') print(code) # 验证code是否正确 old_code = cache.get('cache_mobile_%s' % mobile) if old_code == code or (settings.DEBUG and code == '8888'): # 根据手机号,取用户 user = User.objects.filter(mobile=mobile).first() print(user) if user: return user else: attrs['username'] = mobile attrs['mobile'] = mobile attrs.pop('code') attrs['password'] = '123456' print(attrs) user = User.objects.create_user(**attrs) return user else: raise ValidationError('验证码不正确')
为什么写media才能访问?
django 默认是不允许前端直接访问某个文件夹的
但是有个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media/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
配置文件中debug作用
开发阶段,debug为True,信息会显示的更丰富
访问的路由如果不存在,就会把能访问的路由都显示出来
程序出现异常,错误信息就会直接在浏览器上
自动重启,只要改了代码,就会自动重启
上线阶段,要改成False
ALLOWED_HOSTS的作用
只有debug为False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
万能验证码
在项目中,为了知道是在调试模式还是上线模式,所以才用debug这个字段
判断,如果是开发阶段,可以有个万能验证码
短信登录或者注册接口
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,就说明注册过了,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6位密码,以短信形式通知用户
这个接口,密码为空,下次用账号密码登录,不允许登录
后续改密码:user.set_password(new_password)
查密码check_password()
前端登录注册及页面
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
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 }

redis介绍和安装
1 、redis是什么
数据库就是个存数据的地方:只是不同数据库数据组织,存放形式不一样
mysql 关系型数据库(oracle,sqlserver,postgrasql)
非关系型数据(no sql):redis,mongodb,clickhouse,infludb,elasticsearch,hadoop。。。
没有sql:没有sql语句
not olny sql 不仅仅是sql
redis:一款纯内存存储的非关系型数据库(数据都在内存),速度非常快
2、redis特点:
https://www.cnblogs.com/liuqingzheng/articles/9833534.html
redis是一个key-value存储系统
数据类型丰富,支持5大数据类型:字符串,列表,hash(字典),集合,有序集合
纯内存操作
可以持久化:能都把内存数据,保存到硬盘上永久存储
3、redis为什么这快
1、 纯内存,减少io
2 、使用了 io多路复用的 epoll 网络模型
3、数据操作是单线程,避免了线程间切换
多个客户端同时操作,不会存在并发安全问题
4、安装
redis:最新是7, 公司里5,6比较多
redis:开源软件,免费的,他们不支持win
epoll模型不支持win
微软官方:基于源码修改---》编译成可执行文件
第三方:https://github.com/tporadowski/redis/releases/
win:下载安装包,一路下一步
安装目录在环境变量中:任意路径敲 redis-server reidis-cli 都能找到
把redis做成了服务,以后通过服务启动即可
mac:官网下载,解压即可
win,mac:两个可执行文件:
redis-server :等同于 mysqld
reidis-cli :等同于mysql
5 、启动,连接
5.1 启动方式
使用服务启动
redis-server redis.windows-service.conf
使用命令启动
redis-server
5.2 连接
redis-cli
redis-cli -h 地址 -p 端口(默认端口6379)
5.3 图形化客户端(Navicate)
resp:后来收费了
连接上发现有16个库
6 放值
使用resp放入值
7、取值
cmd中 连接:get key
