[记录四] Vue(全家桶)+node+koa2+mysql+nginx+redis，博客全栈项目之web前端页面完结和路由的编写

导语：

暑假在家闲着无事，就琢磨着做一个web博客练练手，现在已经做完了，把过程分享出来给大家看看，分享一下学习经验。这是第二篇，主要讲node，webpack和vue-cli环境的搭建，使用vue全家桶，完成构建静态页面，写好路由。

一，前端组件的完结

1，顶部功能栏目

<template>
  <div class="top">
    <div class="img_div">
      <img src="../../assets/logomin.jpg" class="img">
      <div class="text">轻松学算法div>

    <div class="tool">
      <div class="sign" @click="login" ref="sign" v-if="!islogin">登陆div>
      <div class="out" @click="logout" ref="out" v-if="islogin">退出div>
      <div class="more" @click="more">更多信息div>
    div>
  div>
template>

<script>

export default {
  methods: {
    more() {
      this.$emit('more')
    },
    login() {
      this.$emit('login')
    },
    logout() {
      this.$emit('logout')
    }
  },
  computed: {
    islogin(){
      return this.$store.getters.getIsLogin
    }
  },
}
script>

<style scoped>

2，顶部导航栏

    div>
  div>
template>

<script>

export default {

      this.$emit('back')
    },
    like() {
      this.$emit('like')
    }
  },
  computed: {

      return this.$store.getters.getIsLogin
    }
  },
}

3，文章详情页面detail

使用了mark去解析.md，并且使用highlight.js把代码部分进行高亮化处理，使得代码阅读变得更加舒服。

二，路由的编写

import Vue from 'vue'
import Router from 'vue-router'
import home from '@/components/home/home'
import article from '@/components/article/article'
import me from '@/components/me/me'
import article_group from '@/components/article_group/article_group'
import article_detail from '@/components/article_detail/article_detail'
import article_new from '@/components/article_new/article_new'
import like from '@/components/like/like'
import imformation from '@/components/imformation/imformation'
Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [
    {
      path: '/',
      redirect: '/home'
    },
    {
      path: '/home',
      name: 'home',
      component: home,
      children: [
        {
          path: ':id',
          component: article_new,
        }
      ]
    },
    {
      path: '/article',
      name: 'article',
      component: article,
      children: [
        {
          path: ':id',
          component: article_group,
          children: [
            {
              path: ':id',
              component: article_detail
            }
          ]
        }
      ]
    },
    {
      path: '/me',
      name: 'me',
      component: me,
      children: [
        {
          path: 'like',
          component: like,
          children: [
            {
              path: ':id',
              component: article_detail
            }
          ]
        },
        {
          path: 'imformation',
          component: imformation
        }
      ]
    }
  ]
})

前端主要是三个主界面，以及一些子组件的构成，运用children子路由，去写好整个应用的路由关系。并且使用路由传参，让子路由拿到信息去调用api接口。

你们的赞就是对我最大的鼓励。谢谢~
