1、簡訊登陸介面
在視圖類 user/views.py中修改並添加:
from .serializer import MulLoginSerializer, SmsLoginSerializer # RegisterSerializer
class LoginView(GenericViewSet):
serializer_class = MulLoginSerializer
queryset = User
# 兩個登陸方式都寫在這裡面（多方式，一個是驗證碼登陸）
# login不是保存，但是用post，咱們的想法是把驗證邏輯寫到序列化類中
@action(methods=["post"], detail=False)
def mul_login(self, request):
return self._common_login(request)
# 127.0.0.1:8000/api/v1/user/login/sms_login
@action(methods=["post"], detail=False)
def sms_login(self, request):
# 默認情況下使用的序列化類使用的是MulLoginSerializer---》多方式登陸的邏輯-->不符合簡訊登陸邏輯
# 再新寫一個序列化類，給簡訊登陸用
return self._common_login(request)
def get_serializer_class(self):
# 方式一：
# if 'mul_login' in self.request.path:
# return self.serializer_class
# else:
# return SmsLoginSerializer
# 方式二
if self.action == 'mul_login':
return self.serializer_class
else:
return SmsLoginSerializer
def _common_login(self, request):
try:
# 序列化類在變
ser = self.get_serializer(data=request.data, context={'request': request})
ser.is_valid(raise_exception=True) # 如果校驗失敗，直接拋異常，不需要加if判斷了
token = ser.context.get('token')
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:lqz}
except Exception as e:
raise APIException(str(e))
from libs import tencent_sms_v3
from django.core.cache import cache
class SendSmsView(ViewSet):
@action(methods=['GET'], detail=False)
def send_message(self, request):
try:
phone = request.query_params.get('phone')
# 生成驗證碼
code = tencent_sms_v3.get_code()
print(code)
# code要保存，否則後面沒法驗證
# sms_cache_%s格式化的字元串可以放到配置文件中---》用戶自定義配置
cache.set('sms_cache_%s' % phone, code, 60) # 設置值，key value形式，key應該唯一，使用手機號
# cache.get() # 取值，根據key取
# 同步操作---》後期可以使用非同步操作---》開一個執行緒調用
res = tencent_sms_v3.send_sms(phone, code)
if res:
return APIResponse(msg='簡訊發送成功')
else:
raise APIException("簡訊發送失敗")
except Exception as e:
raise APIException(str(e))
修改序列化類 user/serializer.py:
from .models import User
from rest_framework import serializers
from rest_framework.exceptions import ValidationError
from django.core.cache import cache
# 這個序列化類，只用來做反序列化，數據校驗，最後不保存，不用來做序列化
class MulLoginSerializer(serializers.ModelSerializer):
# 一定要重寫username這個欄位，因為username這個欄位校驗規則是從User表映射過來的，
# username是唯一，假設資料庫中存在lqz這個用戶，傳入lqz，欄位自己的校驗規則就會校驗失敗，失敗原因是資料庫存在一個lqz用戶了
# 所以需要重寫這個欄位，取消 掉它的unique
username = serializers.CharField(max_length=18, min_length=3) # 一定要重寫，不重寫，欄位自己的校驗過不去，就到不了全局鉤子
class Meta:
model = User
fields = ['username', 'password']
def validate(self, attrs):
# 在這裡面完成校驗，如果校驗失敗，直接拋異常
# 1 多方式得到user
user = self._get_user(attrs)
# 2 user簽發token
token = self._get_token(user)
# 3 把token,username,icon放到context中
self.context['token'] = token
self.context['username'] = user.username
# self.context['icon'] = '//127.0.0.1:8000/media/'+str(user.icon) # 對象ImageField的對象
# self.context['icon'] = '//127.0.0.1:8000/media/'+str(user.icon) # 對象ImageField的對象
request = self.context['request']
# request.META['HTTP_HOST']取出服務端的ip地址
icon = '//%s/media/%s' % (request.META['HTTP_HOST'], str(user.icon))
self.context['icon'] = icon
return attrs
# 意思是該方法只在類內部用，但是外部也可以用，如果寫成__就只能再內部用了
def _get_user(self, attrs):
import re
username = attrs.get('username')
if re.match(r'^1[3-9][0-9]{9}$', username):
user = User.objects.filter(mobile=username).first()
elif re.match(r'^.+@.+$', username):
user = User.objects.filter(email=username).first()
else:
user = User.objects.filter(username=username).first()
if not user:
# raise ValidationError('用戶不存在')
raise ValidationError('用戶名或密碼錯誤')
# 取出前端傳入的密碼
password = attrs.get('password')
if not user.check_password(password): # 學auth時講的，通過明文校驗密碼
raise ValidationError("用戶名或密碼錯誤")
return user
def _get_token(self, user):
# jwt模組中提供的
from rest_framework_jwt.serializers import jwt_payload_handler, jwt_encode_handler
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
return token
# 只用來做反序列化，簡訊登陸
class SmsLoginSerializer(serializers.ModelSerializer):
code = serializers.CharField(max_length=4, min_length=4) # 欄位自己的規則
mobile = serializers.CharField(max_length=11, min_length=11) # 一定要重寫，不重寫，欄位自己的校驗過不去，就到不了全局鉤子
class Meta:
model = User
fields = ['mobile', 'code'] # code不在表中，它是驗證碼，要重新
def validate(self, attrs):
# 1 驗證手機號是否和合法 驗證code是否合法---》去快取中取出來判斷
self._check_code(attrs)
# 2 根據手機號獲取用戶---》需要密碼嗎？不需要
user = self._get_user(attrs)
# 3 簽發token
token = self._get_token(user)
# 4 把token，username，icon放到context中
request = self.context['request']
self.context['token'] = token
self.context['username'] = user.username
self.context['icon'] = '//%s/media/%s' % (request.META['HTTP_HOST'], str(user.icon))
return attrs
def _check_code(self, attrs):
mobile = attrs.get('mobile')
new_code = attrs.get('code')
if mobile:
# 驗證驗證碼是否正確
old_code = cache.get('sms_cache_%s' % mobile)
# 置空
if new_code != old_code:
raise ValidationError('驗證碼錯誤')
else:
raise ValidationError('手機號沒有帶')
def _get_user(self, attrs):
mobile = attrs.get('mobile')
# return User.objects.get(mobile=mobile)
user = User.objects.filter(mobile=mobile).first()
if user:
return user
else:
raise ValidationError("該用戶不存在")
def _get_token(self, user):
# jwt模組中提供的
from rest_framework_jwt.serializers import jwt_payload_handler, jwt_encode_handler
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
return token
2、簡訊註冊介面
在user/urls.py中添加路由：
# 127.0.0.1:8000/api/v1/user/register --- >post請求
router.register('register', RegisterView, 'register')
在視圖類 user/views.py中添加:
from rest_framework.mixins import CreateModelMixin
class RegisterView(GenericViewSet, CreateModelMixin):
serializer_class = RegisterSerializer
queryset = User.objects.all()
def create(self, request, *args, **kwargs):
# 方式一：
super().create(request, *args, **kwargs) # 小問題,code不是表的欄位，需要用write_only
# 方式二：
# serializer = self.get_serializer(data=request.data)
# serializer.is_valid(raise_exception=True)
# # self.perform_create(serializer)
# serializer.save()
return APIResponse(msg='註冊成功')
在序列化類 user/serializer.py 中添加:
# 主要用來做反序列化，數據校驗----》其實序列化是用不到的，但是create源碼中只要寫了serializer.data，就會用序列化
class RegisterSerializer(serializers.ModelSerializer):
code = serializers.CharField(max_length=4, min_length=4, write_only=True)
class Meta:
model = User
fields = ['mobile', 'code', 'password']
extra_kwargs = {
'password': {'write_only': True},
}
def validate(self, attrs):
# 1 校驗手機號和驗證碼
self._check_code(attrs)
# 2 就可以新增了---》User中欄位很多，現在只帶了倆欄位，
# username必填隨機生成，code不存表，剔除，
# 存user表，不能使用默認的create，一定要重寫create方法
self._per_save(attrs)
return attrs
# 校驗手機號
def validate_mobile(self, value): # 局部鉤子
if not re.match(r'^1[3-9][0-9]{9}$', value):
raise ValidationError('手機號不合法')
return value
# 入庫前準備
def _per_save(self, attrs):
# 剔除code，
attrs.pop('code')
# 新增username-->用手機號作為用戶名
attrs['username'] = attrs.get('mobile')
# 寫成公共函數，傳入手機號，就校驗驗證碼
# 經常公司中為了省簡訊，回留萬能驗證碼，8888
def _check_code(self, attrs):
# 校驗code
new_code = attrs.get('code')
mobile = attrs.get('mobile')
old_code = cache.get('sms_cache_%s' % mobile)
if new_code != old_code:
raise ValidationError("驗證碼錯誤")
def create(self, validated_data):
# 如果補充些，密碼不是密文
user = User.objects.create_user(**validated_data)
return user
3、登陸註冊前端
# 打開前端luffycity項目
# 前端可以存數據的地方
存到cookie中，js操作，在vue中可以藉助vue-cookies第三方插件
npm install vue-cookies -S
在main.js中加入：
import cookies from 'vue-cookies'
Vue.prototype.$cookies = cookies;
以後用
this.$cookies.set()
this.$cookies.get()
localStorage，永久存儲
localStorage.setItem('key', 'value');
localStorage.key = "value"
localStorage["key"] = "value"
sessionStorage，臨時存儲，關閉瀏覽器就沒了
sessionStorage.setItem("age",'19')
修改src/components/Login.vue:

4、redis介紹和安裝
# 1 redis
是一個非關係型資料庫(區別於mysql關係型資料庫，關聯關係，外鍵，表)，nosql資料庫(not only sql:不僅僅是SQL)，數據完全記憶體存儲(速度非常快)
# 2 redis就是一個存數據的地方
# 3 redis是
key --value 存儲形式---》value類型有5大數據類型---》字元串，列表，hash(字典)，集合，有序集合
# java:hashMap 存key-value形式
# go：maps 存key-value形式
# 4 redis的好處
(1) 速度快，因為數據存在記憶體中，類似於字典，字典的優勢就是查找和操作的時間複雜度都是O(1)
(2) 支援豐富數據類型，支援string，list，set，sorted set，hash
(3) 支援事務，操作都是原子性，所謂的原子性就是對數據的更改要麼全部執行，要麼全部不執行
(4) 豐富的特性：可用於快取，消息，按key設置過期時間，過期後將會自動刪除
# 5 redis 最適合的場景---》主要做快取---》它又叫快取資料庫
(1) 會話快取（Session Cache）---》存session---》速度快
(2) 介面，頁面快取---》把介面數據，存在redis中
(3) 隊列--->celery使用
(4) 排行榜/計數器--->個人頁面訪問量
(5) 發布/訂閱
# 6 安裝---》c語言寫的開源軟體---》官方提供源碼
如果是在mac或linux上需要 編譯，安裝
redis最新穩定版版本6.x
win：作者不支援windwos，本質原因：redis很快，使用了io多路復用中的epoll的網路模型，這個模型不支援win，所以不支援（看到高性能的伺服器基本上都是基於io多路復用中的epoll的網路模型，nginx），微軟基於redis源碼，自己做了個redis安裝包，但是這個安裝包最新只到3.x，又有第三方組織做到最新5.x的安裝包
安裝包---》編譯完成的可執行文件---》下一步安裝
linux--》make成可執行文件---》make install 安裝
linux，mac平台安裝
# 7 win下載地址
最新5.x版本: //github.com/tporadowski/redis/releases/
最新3.x版本: //github.com/microsoftarchive/redis/releases
一路直接下一步安裝
# mysql 有個圖形化客戶端-Navicat很好用
# redis 也有很多，推薦你用rdb
//github.com/uglide/RedisDesktopManager/releases 收費，99元永久，白嫖
# redis純記憶體操作，有可能把記憶體佔滿了，這個配置是最多使用多少記憶體
# redis服務的啟動與關閉
方式一：安裝完成後 win上，就在服務中了，把服務開啟即可，在服務中啟動關閉
右鍵我的電腦--管理--服務和應用程式--服務--找到redis--右鍵屬性--啟動類型為：自動
方式二：命令啟動，等同於mysqld
redis-server redis.windows-service.conf
# redis連接
命令行：redis-cli -p 埠 -h 地址
客戶端 ：rdb直接連接
