Luffy /4/ 多方式登录接口&登录注册前端页面

现在比较常见的登录方式：手机号+验证码，邮箱+密码，用户名+密码，下面实现一下多方式登录接口

需求接口

# 登陆和注册功能--->5个接口
-多方式登陆接口(手机号，邮箱，用户名 +密码)
-验证手机号是否存在接口
  
-发送短信验证码接口 # 借助于第三方发送短信：阿里，腾讯，容联云通讯，刚注册会送100条短信
-手机号+验证码登陆接口
-手机号+验证码+密码注册接口

腾讯云短信

这里的短信功能使用的是第三方腾讯云，注册公众号申请腾讯云短信功能，会送100条短信供你玩；

申请好公众号，通过该地址//console.cloud.tencent.com/smsv2/guide，设置

"""
创建短信签名
	-签名管理---》创建签名--》使用公众号提交申请---》审核
创建短信正文模板
	-正文模板管理---》创建正文模板--》等审核
发送短信
	-API，SDK
"""

👉官网文档

API和SDK区别

-API接口，通过HTTP调用腾讯云发送短信接口，腾讯负责把短信发送到手机上，HTTP接口基于它来写，比较麻烦，需要我们处理请求参数，或者携带很多参数···

-SDK：第三方使用不同语言封装好了，只需下载导入，调用函数处理即可

使用SDK

# 发短信sdk的使用
# 3.x的发送短信sdk，tencentcloud 包含的功能更多
pip install tencentcloud-sdk-python
# 2.x发送短信sdk：//cloud.tencent.com/document/product/382/11672
# 只是发短信的sdk，功能少，py3.8以后不支持
pip install qcloudsms_py

登录注册前端页面

在实现页面前我们思考如下问题：

如何实现点击登录或图片进行跳转

# 思路：使用vue-router实现页面跳转，跳转就涉及到路由，我们可以先把路由配置好

1.router/index.js中配置要跳转的路由，这里登录举例，写一个Login组件(登录页面)，然后在index.js导入使用：import Login from "@/views/Login";
"""
{
        path: '/login',
        name: 'login',
        component: Login
    }
"""
2. 访问/login路径就能够跳转到登录页面组件
    
    
# 实现点击跳转的两种常用方法
## 方法一：绑定点击事件，实现点击跳转
   this.$router.push('/login')
## 方法二：使用 <router-link to=""></router-link>标签实现跳转
  注册：<router-link to="/login"><span>注册</span></router-link>
  图片：<router-link to="/">
         <img src="../assets/img/head-logo.svg" alt="">
        </router-link>  

<router-link to=""></router-link>标签实现跳转第三方

数据库添加第三方link

demo

<!--  跳第三方  -->
<!--如果图片的跳转路径不包含http，那么就跳转本地 -->
<div v-if="!(item.link.indexOf('http')>-1)">
	<router-link :to="item.link">
        <img :src="item.image" alt="课程图">
     </router-link>
</div>
<!-- 如果图片包含了http那么就跳转第三方 -->
<div v-else>
	<a :href="item.link"> 
    <img :src="item.image" alt="课程图">
    </a>
</div>

如果不进行处理，router-link标签只能跳转本地，如果想要跳转第三方(百度，博客···)需要进一步处理！

登录注册前端页面实现

实现的样式是基于弹出框实现，弹出的是模态框

接口实现1

验证手机号是否存在接口

思路：数据库查询，存在返回{“code”:“100”,“msg”:“成功”}

users/views.py

from .models import User
from utils.reponse import APIResponse
from rest_framework.exceptions import APIException
from rest_framework.viewsets import ViewSet
from rest_framework.decorators import action

class MobilePhone(ViewSet):
    @action(methods=['GET'],detail=False)
    def check_mobile(self,request):
        try:
            # 从请求参数获取手机号
            mobile = request.query_params.get('mobile')
            User.objects.get(mobile=mobile)
            # 存在返回`{“code”:“100”,“msg”:“成功”}`
            return APIResponse()
        except Exception as e:
            raise APIException(str(e))

users/urls.py

from django.urls import path, include
from rest_framework.routers import SimpleRouter
from .views import UserView

router = SimpleRouter()
# 127.0.0.1:8000/api/v1/user/mobile/check_mobile
router.register('mobile',UserView , 'mobile')
urlpatterns = [
    path('', include(router.urls)),
]

多方式登录接口

视图

from .models import User
from utils.reponse import APIResponse
from rest_framework.exceptions import APIException
from rest_framework.viewsets import ViewSet,GenericViewSet
from rest_framework.decorators import action


# 验证手机号是否存在
class MobileView(ViewSet):
    @action(methods=['GET'],detail=False)
    def check_mobile(self,request):
        try:

            mobile = request.query_params.get('mobile')
            User.objects.get(mobile=mobile)
            # 存在返回`{“code”:“100”,“msg”:“成功”}`
            return APIResponse()
        except Exception as e:
            raise APIException(str(e))


# 多方式登录
from .serializer import MulLoginSerializer


class LoginView(GenericViewSet):
    serializer_class = MulLoginSerializer
    queryset = User

    # 两个登陆方式都写在这里面（多方式，一个是验证码登陆）
    # login不是保存，但是用post，咱们的想法是把验证逻辑写到序列化类中
    @action(methods=["post"], detail=False)
    def mul_login(self, request):

            username = ser.context.get('username')
            icon = ser.context.get('icon')
            return APIResponse(token=token, username=username, icon=icon)  # {code:100,msg:成功，token:dsadsf,username:Hammer}
        except Exception as e:
            raise APIException(str(e))

序列化类

# 这个序列化类，只用来做反序列化，数据校验，最后不保存，不用来做序列化
class MulLoginSerializer(serializers.ModelSerializer):
    # 一定要重写username这个字段，因为username这个字段校验规则是从User表映射过来的，
    # username是唯一，假设数据库中存在HammerZe用户，传入HammerZe用户，字段自己的校验规则就会校验失败，失败原因是数据库存在一个HammerZe用户了
    # 所以需要重写这个字段，取消 掉它的unique
    username = serializers.CharField(max_length=18, min_length=3)  # 一定要重写，不重写，字段自己的校验过不去，就到不了全局钩子

    class Meta:
        model = User
        fields = ['username', 'password']

    def validate(self, attrs):
        # 在这里面完成校验，如果校验失败，直接抛异常
        # 1 多方式得到user
        user = self._get_user(attrs)
        # 2  user签发token
        token = self._get_token(user)
        # 3  把token,username,icon放到context中
        self.context['token'] = token
        self.context['username'] = user.username
        # 写死的路径

        icon = '//%s/media/%s' % (request.META['HTTP_HOST'], str(user.icon))
        self.context['icon'] =icon
        return attrs

    # 正则校验登录方式
    # 意思是该方法只在类内部用，但是外部也可以用，如果写成__就只能再内部用了
    def _get_user(self, attrs):
