cd C:\node_workspace\two
# 安装项目依赖文件
cnpm install
# 项目启动
cnpm run dev

Vue 之 移除初始化模板样式和数据

1、在App.vue 文件中移除原有Vue的logo 标签和样式文件。下面是修改后的App.Vue 文件

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

<style>
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}
html,body{
  width: 100%;
  height: 100%;
}
#app {
  height: 100%;
}
</style>

Vue 之Vuex 功能封装

1、在src 文件夹下新增store 文件夹并新增index.js 。index.js 新增内容如下:

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex);
 
const store = new Vuex.Store({
 
  state: {
    // 存储token
    token: localStorage.getItem('token') ? localStorage.getItem('token') : ''
  },
 
  mutations: {
    // 修改token，并将token存入localStorage
    changeLogin (state, user) {
      state.token = user.token;
      localStorage.setItem('token', user.token);
    },
    logout (state, user) {
        state.token = ''
        localStorage.removeItem('token')
      }
  

  }
});
 
export default store;

Vue 之Element-ui、axios、store功能基础

1、在mian.js 集成element-ui、axios、store 。main.js 内容如下:

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
// 集成element-ui
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
// 集成vuex
import store from'./store'
// 集成axios
import axios from '../node_modules/axios'

// 设置跨域
axios.defaults.withCredentials = true
// 设置后端请求地址
axios.defaults.baseURL='http://192.168.1.74:8198/house'
Vue.prototype.$axios = axios

Vue.use(ElementUI);
Vue.config.productionTip = false

// 添加请求拦截器，在请求头中加token
axios.interceptors.request.use(
  config => {
    if (localStorage.getItem('token')) {
      config.headers.token = localStorage.getItem('token');
    }
    return config;
  },
  error => {
    return Promise.reject(error);
  });
 
// 添加响应拦截器，移除token
axios.interceptors.response.use(
  response =>{
    return response;
  },
  error=>{
    if(error.response){
      switch(error.response.status){
        case 401:
          localStorage.removeItem('token');
          this.$router.push('/login');
      }
    }
  })

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  store,
  components: { App },
  template: '<App/>'
})

Vue 之路由配置

1、重点修改router文件夹下的index.js 文件，index.js 配置文件内容如下:

import Vue from 'vue'
import Router from 'vue-router'
import login from '@/components/login';
import home from '@/components/home';
// 新房管理
import newHouse from '@/components/view/newHouse'
// 二手房管理
import secondHouse from '@/components/view/secondHouse'

Vue.use(Router)

const router = new Router({
  routes: [
    {
      path: '/',
      redirect: '/login'
    },
    {
      path: '/login',
      name: 'login',
      component: login
    },
    {
      path: '/home',
      name: 'home',
      component: home,
      children: [{
        path: '/newHouse',
        name: 'newHouse',
        component: newHouse
      },
      {
        path: '/secondHouse',
        name: 'secondHouse',
        component: secondHouse
      }]
    }
  ]
})

// 导航守卫
// 使用 router.beforeEach 注册一个全局前置守卫，判断用户是否登陆
router.beforeEach((to, from, next) => {
  if (to.path === '/login') {
    next();
  } else {
    let token = localStorage.getItem('token');
    if (token === null || token === '') {
      next('/login');
    } else {
      next();
    }
  }
});

export default router;

Vue 组件之 login.vue（登入首页）

<template>
   <div class="login-container">
    <el-form label-position="left"
      label-width="0px"
      status-icon>
        <h3 class="login_title">系统登录</h3>
        <el-form-item>
          <el-input
            type="text"
            v-model="loginForm.username"
            auto-coplete="off"
            placeholder="账号">
          </el-input>
        </el-form-item>
        <el-form-item>
          <el-input
            type="password"
            v-model="loginForm.password"
            auto-coplete="off"
            placeholder="密码">
          </el-input>
        </el-form-item>
        <el-form-item style="width: 100%">
          <el-button type="primary" @click.native.prevent="login" style="width: 100%">登录</el-button>
          <!--
          <el-button type="primary" @click.native.prevent="register" style="width: 100%; margin-top: 30px">注册</el-button>
          -->
        </el-form-item>
      </el-form>
  </div>

</template>
 
<script>
import { mapMutations } from 'vuex';
export default {
  data () {
    return {
      loginForm: {
        username: '',
        password: ''
      },
      userToken: ''
    };
  },
 
  methods: {
    // 调用store 存储
    ...mapMutations(['changeLogin']),
    login () {
      let _this = this;
      if (this.loginForm.username === '' || this.loginForm.password === '') {
        alert('账号或密码不能为空');
      } else {
        // 发起登入请求
        this.$axios({
          method: 'post',
          url: '/auth/login',
          headers: {
		     'Content-Type':'application/json;charset=utf-8' 
	      },
          data:{"username":_this.loginForm.username,"password":_this.loginForm.password},
        }).then(res => {
          console.log('123456');
          console.log(res);
          console.log(res.data.datas.token);
          _this.userToken = res.data.datas.token;
          // 将用户token保存到vuex中
          _this.changeLogin({ token: _this.userToken });
          // 用户登入成功,自动跳转至系统首页
          _this.$router.push('/home');
          alert('登陆成功');
        }).catch(error => {
          alert('账号或密码错误');
          console.log(error);
        });
      }
    }
  }
};
</script>
<style scoped>
.login-container{
  border-radius: 15px;
  background-clip: padding-box;
  margin: 10% auto;
  width: 350px;
  padding: 35px 35px 15px 35px;
  background: #fff;
  border: 1px solid #eaeaea;
  box-shadow: 0 0 25px #cac6c6;
}
.login_title{
  margin: 0px auto 40px auto;
  text-align: center;
  color: #505458;
}
</style>

Vue 组件之 home.vue（系统首页）

<style>
.el-main {
  background-color: #f5f7f9;
}
.el-header,
.el-footer {
  background-color: white;
  box-sizing: border-box;
  border-bottom: 1px solid #f5f1f1;
}
.el-container {
  height: 100%;

export default {
  components: {
    navtop,
    leftNav
  },
  data() {
    return {};
  },

</script>

Vue 组件之 系统首页涉及公共页面（nav-top.vue 和nav.vue）

注意:在src/components/part 新增上述两个vue 文件

nav-top.vue

<style scoped>
.el-aside {
    display: flex;
    justify-content: center;
    align-items: center;

<script>
export default {
  data() {
    return {
      activeIndex: "1",
    };
  },
  methods: {
    handleSelect(key, keyPath) {
      console.log(key, keyPath);
    }
  }
};
</script>

nav.vue

<style scoped>
.el-row{
  height: 100%;
}
.el-menu{
  border-right:none;

          @close="handleClose"
        >
          <el-menu-item index="1" @click="goPage('centre')">
            <i class="el-icon-menu"></i>
            <span slot="title">首页</span>
          </el-menu-item>

          <el-submenu index="3">
            <template slot="title">
              <i class="el-icon-location"></i>
              <span>房屋管理</span>
            </template>
            <el-menu-item-group>
              <el-menu-item index="3-1" @click="goPage('newHouse')">新房管理</el-menu-item>

<script>
var $this = {};
export default {
  data() {
    return {};
  },
  beforeCreate() {
    $this = this;
  },
  methods: {
    handleOpen(key, keyPath) {
      console.log(key, keyPath);
    },
    handleClose(key, keyPath) {
      console.log(key, keyPath);
    },
    goPage(link) {
    // 跳转至首页
      if (link === "centre") {
        $this.$router.push("/centre").catch(error => error);
      }
      // 跳转至会员管理 
      else if ((link === "newHouse")) {
        $this.$router.push("/newHouse").catch(error => error);
      } 
      // 跳转至收获地址
      else if ((link === "secondHouse")) {
        $this.$router.push("/secondHouse").catch(error => error);
      } 
     
    }
  }
};
</script>
