Vue Element Admin 登陆认证
使用的是Vue Element Admin template 基础模板
1 修改 src/api/user.js
import request from '@/utils/request'
export function login(data) {
return request({
url: '/auth/',
method: 'post',
data
})
}
export function getInfo(token) {
return request({
url: '/userInfo/',
method: 'post',
data:{'token':token}
})
}
export function logout() {
return request({
url: '/logout/',
method: 'post'
})
}
2 修改src/store/modules/user.js
import { login, logout, getInfo } from '@/api/user'
import { getToken, setToken, removeToken } from '@/utils/auth'
import { resetRouter } from '@/router'
const getDefaultState = () => {
return {
token: getToken(),
name: '',
avatar: ''
}
}
const state = getDefaultState()
const mutations = {
RESET_STATE: (state) => {
Object.assign(state, getDefaultState())
},
SET_TOKEN: (state, token) => {
state.token = token
},
SET_NAME: (state, name) => {
state.name = name
},
SET_AVATAR: (state, avatar) => {
state.avatar = avatar
}
}
const actions = {
// user login
login({ commit }, userInfo) {
const { username, password } = userInfo
return new Promise((resolve, reject) => {
login({ username: username.trim(), password: password }).then(response => {
const { data } = response.data
commit('SET_TOKEN', data.token)
setToken(data.token)
resolve()
}).catch(error => {
reject(error)
})
})
},
// get user info
getInfo({ commit, state }) {
return new Promise((resolve, reject) => {
getInfo(state.token).then(response => {
const { data } = response.data
if (!data) {
return reject('Verification failed, please Login again.')
}
const { name, avatar } = data
commit('SET_NAME', name)
commit('SET_AVATAR', avatar)
resolve(data)
}).catch(error => {
reject(error)
})
})
},
// user logout
logout({ commit, state }) {
return new Promise((resolve, reject) => {
logout(state.token).then(() => {
removeToken() // must remove token first
resetRouter()
commit('RESET_STATE')
resolve()
}).catch(error => {
reject(error)
})
})
},
// remove token
resetToken({ commit }) {
return new Promise(resolve => {
removeToken() // must remove token first
commit('RESET_STATE')
resolve()
})
}
}
export default {
namespaced: true,
state,
mutations,
actions
}
3,修改src/utils/request.js
import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'
// create an axios instance
const service = axios.create({
baseURL: process.env.VUE_APP_BASE_URL, // url = base url + request url
// withCredentials: true, // send cookies when cross-domain requests
timeout: 5000 // request timeout
})
// request interceptor
service.interceptors.request.use(
config => {
// do something before request is sent
if (store.getters.token) {
// let each request carry token
// ['X-Token'] is a custom headers key
// please modify it according to the actual situation
//把Token信息加到请求头部
config.headers['X-Token'] = getToken()
}
return config
},
error => {
// do something with request error
console.log(error) // for debug
return Promise.reject(error)
}
)
export default service
4 配置后端接口
from django.http import JsonResponse
from rest_framework.views import APIView
from api import models
from api.logger import logger
def create_token(user):
import hashlib
import time
#获取当前时间戳用作随机字符串
ctime = str(time.time())
m = hashlib.md5(bytes(user,encoding='utf-8'))
m.update(bytes(ctime,encoding='utf-8'))
return m.hexdigest()
class AuthView(APIView):
"""
用户登陆认证，生成并保存token
"""
authentication_classes = []
def post(self,request,*args,**kwargs):
ret = {"code": 200, "status": "success", "data": {"token": None}}
username = request.data.get('username')
password = request.data.get('password')
try:
obj = models.Users.objects.filter(username=username,password=password).first()
if obj:
#为用户创建token,如果已存在则更新，否则创建
token = create_token(username)
models.UserToken.objects.update_or_create(user=obj,defaults={'token':token})
ret['status'] = 'success'
ret['data']['token'] = token
else:
ret['code'] = 401
ret['status'] = '用户名或密码错误'
except Exception as e:
logger.error(e)
ret['code'] = 400
ret['status'] = 'error'
return JsonResponse(ret)
class AuthInfoView(APIView):
"""
获取登陆用户信息
"""
def post(self,request,*args,**kwargs):
ret = {"code":200,"status":"success","data":{"roles":[],"introduction": '',
"avatar": 'https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif',
"name": ''}}
token = request.data.get('token')
try:
obj = models.UserToken.objects.filter(token=token).first()
if obj:
ret['status'] = 'success'
ret['data']['name'] = obj.user.username
for i in obj.user.roles.all():
ret['data']['roles'].append(i.title)
else:
ret['code'] = 401
ret['status'] = '认证失败'
except Exception as e:
logger.error(e)
ret['code'] = 400
ret['status'] = 'error'
return JsonResponse(ret)
class LogoutView(APIView):
"""
退出登陆
"""
def post(self,request,*args,**kwargs):
ret = {"code":200,"status":"success","data":'success'}
token = request.META.get('HTTP_X_TOKEN')
try:
obj = models.UserToken.objects.filter(token=token).first()
if obj:
obj.delete()
else:
ret['code'] = 401
ret['status'] = '退出失败'
except Exception as e:
logger.error(e)
ret['code'] = 400
ret['status'] = 'error'
return JsonResponse(ret)
5 后端token认证
from rest_framework import exceptions
from rest_framework.authentication import BaseAuthentication
from api import models
class Authentication(BaseAuthentication):
def authenticate(self, request):
#获取请求头部的token
token = request.META.get('HTTP_X_TOKEN')
token_obj = models.UserToken.objects.filter(token=token).first()
if not token_obj:
raise exceptions.AuthenticationFailed('用户认证失败')
return (token_obj.user,token_obj)
ps:携带token认证时出现了跨域问题(中间件配置)
from django.utils.deprecation import MiddlewareMixin
class CORSMiddleware(MiddlewareMixin):
def process_response(self, request, response):
# 添加响应头
# 允许你的域名来获取我的数据
# 允许所有的域名来获取数据
response['Access-Control-Allow-Origin'] = '*'
# 允许你携带Content-Type请求头 如果要多的用逗号,隔开
response['Access-Control-Allow-Headers'] = '*'
return response
配置setting
MIDDLEWARE = [
'api.cors.CORSMiddleware', #跨域请求CORS
]
