vue登录注册实例详解

时间:2020-05-17 我想我会成功人气:0

步骤一

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" class="demo-ruleForm login-container">
 <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: '/',
   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:'/'})
      }else{
       this.$message.error(res.result.error)
      }
     })
    }
   })
  }
 }
