vue登录注册实例详解

1.安装脚手架:npm install vue-cli -g
2.wepack生成html模版：vue init webpack ' 文件名'
3.安装axios、js-cookie、element-ui、stylus等等常用插件

步骤二

1.在main.js中引入router、element-ui等

import Vue from 'vue' import store from './store' //可以先忽略 import App from './App' import router from './router' import ElementUI from 'element-ui' import 'element-ui/lib/theme-chalk/index.css' Vue.config.productionTip = false Vue.use(ElementUI) /* eslint-disable no-new */ new Vue({ el: '#app', router, store, render: h => h(App) })

2.可以写组件了

<template> <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px"> <el-form-item label="账号" prop="name"> <el-input v-model="ruleForm.name"></el-input> </el-form-item> <el-form-item label="密码" prop="pass"> <el-input type="password" v-model="ruleForm.pass" auto-complete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm">提交</el-button> </el-form-item> </el-form> </template> <script> export default { data() { return { ruleForm: { name: '', pass: '' }, rules: { name: [ { required: true, message: '请输入登录账号', trigger: 'blur' } ], pass: [ { required: true, message: '请输入登录密码', trigger: 'blur' } ] } } }, }

步骤三

走到这一步就很懵逼了吧，，， 我也是，所以还是先看到效果先吧

1.注册组件，在router文件这里

import Vue from 'vue' import Router from 'vue-router' import Login from 'components/login/index' const _import = require('./_import_' + process.env.NODE_ENV)//没用上当没看见吧，我就是要写这 Vue.use(Router) export const constantRouterMap = [ { path: 'https://www.jb51.net/', component:Login, name:'登录' }, ] export default new Router({ routes: constantRouterMap })

emmmm....我猜组件应该渲染出来了，很好！next

步骤四

关键性的步骤到了，看起来很难的vuex

1.第一步，先写好接口方便调用，放在api文件夹里的login.js

import axios from 'axios' import { server } from './config' // 登陆 export const requestLogin = params => { return axios.post(server + '/jade/user/loginManage.action', params, { withCredentials: true, // 跨域凭证 transformRequest: [function(data) { let ret = '' for (const it in data) { ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&' } // axios官方文档关于怎么用每个参数是什么说的特别特别清楚，我百度过的 return ret }], headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }).then(res => { return Promise.resolve(res.data) }, err => { console.log(err) }) }

2.利用js-cookie插件来存储用户信息

import Cookie from 'js-cookie' export function getToken() { return Cookie.get(TokenKey) } export function setToken(token) { return Cookie.set(TokenKey, token) } export function removeToken() { return Cookie.remove(TokenKey) } export function getRole() { return sessionStorage.getItem('rules') }

3.好了可以写actions了

import { requestLogin } from 'api/login' import { getToken,setToken,removeToken } from '../../utils/auth' const user = { state: { token: getToken(), name: '', avatar: '' }, mutations: { SET_TOKEN: (state, token) => { state.token = token } }, actions: { // 登录 Login ({commit}, userInfo) { const account = userInfo.account const password = userInfo.checkPass return new Promise((resolve, reject) => { console.log(resolve) console.log(reject) let params = { account: account, password: password } requestLogin(params).then(response => { const data = response.result setToken(data.sid) sessionStorage.setItem('accountType', data.accountType) commit('SET_TOKEN', data.sid) resolve(response) }).catch(error => { reject(error) }) }) } } } export default user

3.别忘了要注册store

import Vue from 'vue' import Vuex from 'vuex' import user from './modules/user' Vue.use(Vuex) const store = new Vuex.Store({ modules: { user, } }) export default store

最后一步使用,回到组件

methods: { submitForm() { this.$refs.ruleForm.validate((valid)=>{ if(valid) { console.log(this.$store) this.$store.dispatch('Login',this.ruleForm).then((res)=>{ console.log(res) if(res.success) { this.$router.push({path:'https://www.jb51.net/'}) }else{ this.$message.error(res.result.error) } }) } }) } }

以上就是本次介绍的全部知识点，感谢大家对脚本之家的支持。
