## 2 登陆注册接口分析
```python
# 1 多方式登录接口
# 2 手机号登录接口
# 3 发送验证码接口
# 4 注册接口
# 5 校验手机号是否存在接口
```
## 3 多种登陆方式
```python
# 路由
from django.urls import path,include
from . import views
from rest_framework.routers import SimpleRouter
router=SimpleRouter()
router.register('',views.LoginView,'login')
urlpatterns = [
path('',include(router.urls) ),
]
# 视图类
from rest_framework.viewsets import ViewSet
from . import serializer
from luffyapi.utils.response import APIResponse
from rest_framework.decorators import action
class LoginView(ViewSet):
@action(methods=['POST'],detail=False)
def login(self,request,*args,**kwargs):
ser=serializer.UserSerilaizer(data=request.data)
if ser.is_valid():
token=ser.context['token']
username=ser.context['user'].username
return APIResponse(token=token,username=username)
else:
return APIResponse(code=0,msg=ser.errors)
# 序列化类
from rest_framework import serializers
from . import models
from rest_framework.exceptions import ValidationError
class UserSerilaizer(serializers.ModelSerializer):
username=serializers.CharField()
class Meta:
model=models.User
fields=['username','password','id']
extra_kwargs={
'id':{'read_only':True},
'password':{'write_only':True}
}
def validate(self, attrs):
# 多种登录方式
user=self._get_user(attrs)
# 签发token
token=self._get_token(user)
# 放到context中，我在视图类中可以取出来
self.context['token']=token
self.context['user']=user
return attrs
def _get_user(self,attrs):
username = attrs.get('username')
password = attrs.get('password')
import re
if re.match('^1[3-9][0-9]{9}$',username):
user=models.User.objects.filter(telephone=username).first()
elif re.match('^.+@.+$',username): #邮箱
user=models.User.objects.filter(email=username).first()
else:
user=models.User.objects.filter(username=username).first()
if user:
ret=user.check_password(password)
if ret:
return user
else:

from rest_framework_jwt.serializers import jwt_payload_handler,jwt_encode_handler
payload=jwt_payload_handler(user) # 通过user对象获得payload
token=jwt_encode_handler(payload) # 通过payload获得token
return token
```
## 4 cookies修改页面登陆状态
```python
1 重点，cookie操作
this.$cookies.set('key',value,过期时间秒)
this.$cookies.get('key')
this.$cookies.remove('key')
2
# template
<el-button type="primary" @click="login_password">登录</el-button>
#js
login_password() {
if (this.username && this.password) {
//发送请求
this.$axios.post(this.$settings.base_url + '/user/login/', {
username: this.username,
password: this.password
}).then(response => {
console.log(response.data)
//把用户信息保存到cookie中
// this.$cookies.set('key','value','过期时间,按s计')
this.$cookies.set('token',response.data.token,'7d')
this.$cookies.set('username',response.data.username,'7d')
//关闭登录窗口(子传父)
this.$emit('close')
//给父组件，Head传递一个事件，让它从cookie中取出token和username
this.$emit('loginsuccess')
}).catch(errors => {
})
} else {
this.$message({
message: '用户名或密码必须填哦',
type: 'warning',
});
}
},
```
## 5 前台注销
```python
# Head.vue
### template
<span @click="logout">注销</span>
### js
logout(){
//清除cookie
this.$cookies.remove('token')
this.$cookies.remove('username')
//把两个变量值为空
this.username=''
this.token=''
},
```
## 6 手机号是否存在接口
```python
# urls.py 如果不重写视图类不需要动
# views.py
class LoginView(ViewSet):
@action(methods=['GET'], detail=False)
def check_telephone(self,request,*args,**kwargs):
import re
telephone=request.query_params.get('telephone')
if not re.match('^1[3-9][0-9]{9}',telephone):
return APIResponse(code=0,msg='手机号不合法')
try:
models.User.objects.get(telephone=telephone)
return APIResponse(code=1)
except:
return APIResponse(code=0,msg='手机号不存在')
```
## 7 腾讯云短信服务
```python
#0 注册一个公众号（）
-https://mp.weixin.qq.com/
-注册订阅号，一路下一步，申请个人
-截一个图（首页）
#1 腾讯云，---注册---实名：-https://console.cloud.tencent.com/smsv2
#2 https://console.cloud.tencent.com/smsv2/csms-sign/create
-把图传上去，认证
#3 创建模板（审核）
#4 应用管理（创建一个应用，记住appid和App Key）
#5 扣代码（https://cloud.tencent.com/document/product/382/11672）
# 7 帮助文档
-API：一堆web接口，基于API接口来写
-SDK：软件开发工具包软件,别人基于api接口，用不同语言封装的工具包，我们可以直接调用方法完成某些事
```
