在GitHub上有很多写好的模板,这个项目也是基于模板做的。
现在记录一下我做的过程
1、修改config文件夹里的dev.env.js里的BASE_API,把地址改成请求后端的公共部分
BASE_API: '"http://192.168.xx.xx"',
2、接下来就是操作src文件,先在 views里写好vue组件(login.vue,regist.vue),写好到router里的index.js里配置好路径
login.vue
登录
登录
router/index.js
{ path: '/login', component: _import('Login/login'), hidden: true }
3、在api里的login.js里写好与后端对接的接口地址,在stores里的modules里的user.js里定义user,有state,mutations,action,具体的请求操作写在action里,login.vue或regist.vue调用user.js里写好的请求,getter.js里定义store的getters
api/login.js
import request from '@/utils/request'
export function login(name,password) {
return request({
url: '/XX/XX',
method: 'post',
data: {
name,
password
}
})
}
stores/modules/user.js
import { login,regist,logout } from '@/api/login'
import { getToken,setToken } from '@/utils/auth'
const user = {
state: {
name:'',
token:''
},
mutations: {
SET_NAME: (state, name) => {
state.name = name;
},
SET_TOKEN: (state, token) => {
state.token = token;
setToken(token);
}
},
actions: {
// 登录
Login({ commit }, userInfo) {
const name = userInfo.name.trim();
const password = userInfo.password.trim();
return new Promise((resolve, reject) => {
login(name, password).then(response => {
const data = response.data;
commit('SET_NAME', data.name);
commit('SET_TOKEN', data.token);
setName(data.name);
setToken(data.token);
resolve(response); }).catch(error => { reject(error) }) }) },
// 注册
Regist({ commit }, userInfo) {
const name= userInfo.name.trim();
const password = userInfo.password.trim();
return new Promise((resolve, reject) => {
regist(name, password).then(response => {
const data = response.data;
commit('SET_NAME', data.name);
commit('SET_TOKEN', data.token);
setName(data.name);setToken(data.token);
resolve(response);
}).catch(error => {
reject(error) }) }) },
// 登出
LogOut({ commit, state }) {
return new Promise((resolve, reject) => {
logout().then(response => {
commit('SET_NAME', '');
commit('SET_TOKEN', '');
setName('');
setToken(false);
//removeName();
//removeToken();
resolve(response);
}).catch(error => {
reject(error)
})
})
},
// 前端 登出
FedLogOut({ commit }) {
return new Promise(resolve => {
setToken(false);
commit('SET_TOKEN', false);
resolve()
})
}
}
}
export default user
getter.js:
const getters={
name:state=>state.user.name,
token:state=>state.user.token
}
export default getter
4、在utils里的auth.js里对cookies进行操作,写入,读取,删除用户权限,是否登录的标志等
import Cookies from 'js-cookies'
export function setName(name) {
return Cookies.set("name", name);
}
export function getName() {
return Cookies.get("name");
}
export function setToken(token) {
return Cookies.set("token", token);
}
export function getToken() {
return Cookies.get("token");
}
5、在permission.js里写白名单,对白名单以外的跳转进行拦截然后跳转登录,同时判断用户权限,是否登录,等
import router from './router'
import store from './store'
import NProgress from 'nprogress' // Progress 进度条
import 'nprogress/nprogress.css'// Progress 进度条样式
import {Message} from 'element-ui'
import {getName, getToken} from "@/utils/auth"; // 验权
const whiteList = ['/login', '/regist']; // 不重定向白名单
router.beforeEach((to, from, next) => {
NProgress.start();
if (whiteList.indexOf(to.path) !== -1) {
next();
} else {
if (getToken()==="true") {
next();
NProgress.done()
} else {
next({path: '/login'});
NProgress.done()
}
}
})
router.afterEach(() => {
NProgress.done() // 结束Progress
})
6、utils里的request.js里写拦截码,对后端返回的特定码进行拦截然后做相应的操作
import axios from 'axios'
import { Message, MessageBox } from 'element-ui'
import store from '../store'
// 创建axios实例
const service = axios.create({
baseURL: process.env.BASE_API, // api的base_url
timeout: 15000 // 请求超时时间
});
// respone拦截器
service.interceptors.response.use(
response => {
/**
* code为非200是抛错 可结合自己业务进行修改
*/
const res = response.data;
//const res = response;
if (res.code !== '200' && res.code !== 200) {
if (res.code === '4001' || res.code === 4001) {
MessageBox.confirm('用户名或密码错误,请重新登录', '重新登录', {
confirmButtonText: '重新登录',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
store.dispatch('FedLogOut').then(() => {
location.reload()// 为了重新实例化vue-router对象 避免bug
})
})
}
if (res.code === '4009' || res.code === 4009) {
MessageBox.confirm('该用户名已存在,请重新注册!', '重新注册', {
confirmButtonText: '重新注册',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
store.dispatch('FedLogOut').then(() => {
location.reload()// 为了重新实例化vue-router对象 避免bug
})
})
}
return Promise.reject('error')
} else {
return response.data
}
},
error => {
Message({
message: error.message,
type: 'error',
duration: 5 * 1000
});
return Promise.reject(error)
}
)
export default service
