标签:script   引入   a10   bsp   substring   lis   return   .com   pre   

一、抽出头部作为一个组件,在底部导航的时候可以相应的显示不同的标题

技术点:使用slot进行组件间的通信;父组件给子组件传值(子组件里面通过props接收父组件传过来的数据)

            <a class="header_title">
                <span class="header_title_text ellipsis">{{title}}</span>
            </a>
            <slot name="login"></slot>

            <router-link slot="search" to="/search" class="header_search">
                <i class="iconfont icon-sousuo"></i>
            </router-link>
            <router-link slot="login" to="/login" class="header_login">
                <span class="header_login_text">登录|注册</span>
            </router-link>
        </HeaderTop>

import HeaderTop from ‘../../components/HeaderTop/HeaderTop.vue‘

二、抽出商家列表编辑成单独组件

三、编辑登录界面

提示:返回前面的路由使用 $router.back()

        >.iconfont
          font-size 20px
          color #999
</style>
Login.vue

然后注册Login路由

router/index.js

技术分享图片
//引入组件
import Login from ‘../pages/Login/Login.vue‘

 {
      path: ‘/login‘,
      component: Login
    }
View Code

 

四、控制底部导航的显示隐藏。

注意:此时底部导航FooterGuide仅仅在Msite,Order,Search,Profile才显示,Login上不会显示。

技术点:v-show="$route.meta.show"

https://segmentfault.com/q/1010000007648124

技术分享图片
<template>
    <div id="app">
        <router-view/>
        <FooterGuide v-show="$route.meta.showFooter"></FooterGuide>
    </div>
</template>
App.vue

router/index.js

技术分享图片
export default new Router({
  routes: [
    {
      path: ‘/‘,
      redirect: ‘/msite‘
    },
    {
      path: ‘/msite‘,
      component: Msite,
      meta: {
        showFooter: true
      }
    },
    {
      path: ‘/search‘,
      component: Search,
      meta: {
        showFooter: true
      }
    },
    {
      path: ‘/order‘,
      component: Order,
      meta: {
        showFooter: true
      }
    },
    {
      path: ‘/profile‘,
      component: Profile,
      meta: {
        showFooter: true
      }
    },
    {
      path: ‘/login‘,
      component: Login
    }
  ]
})
index.js

 

从这开始做后台数据交互应用

 

五、封装ajax请求。

api/ajax.js

提示:使用axios

技术分享图片
import axios from ‘axios‘

export default function ajax(url = ‘‘, data = {}, type = ‘GET‘){
    return new Promise(function (resolve, reject) {
        let promise
        if (type === ‘GET‘) {
            // 准备 url query 参数数据
            let dataStr = ‘‘
            Object.keys(data).forEach(key => {
                dataStr += key + ‘=‘ + data[key] + ‘&‘
            })
            if (dataStr !== ‘‘) {
                dataStr = dataStr.substring(0,dataStr.lastIndexOf(‘&‘))
                url = url + ‘?‘ + dataStr
            }
            // 发送get请求
            promise = axios.get(url)
        }else {
            // 发送post请求
            promise = axios.post(url,data)
        }
        promise.then(response => {
            resolve(response.data)
        })
        .catch(error => {
            reject(error)
        })
    })
}
View Code

然后根据api接口类型设置请求函数的路由

api/index.js

技术分享图片
import ajax from ‘./ajax.js‘

// 根据经纬度获取位置详情
export const reqAddress = (geohash) => ajax(`/position/${geohash}`)

// 获取食品的分类列表
export const reqFoodCategories = () => ajax(‘/index_category‘)

// 根据经纬度获取商铺列表
export const reqShops = (longitude,latitude) => ajax(‘/shops‘,{longitude,latitude})

// 账号密码登录
export const reqPwdLogin = (name,pwd,captcha) => ajax(‘/api/login_pwd‘,{
    name,
    pwd,
    captcha
},‘POST‘)

// 获取短信验证码
export const reqSendCode = phone => ajax(‘/api/sendcode‘,{phone})

// 手机号验证码登录
export const reqSmsLogin = (phone,code) => ajax(‘/api/login_sms‘,{phone,code},‘POST‘)

// 获取用户信息
export const reqUser = () => ajax(‘/api/userinfo‘)

// 请求登出
export const reqLogout = () => ajax(‘/api/logout‘)
View Code

 

六、配置webpack实现跨域

查看链接:https://www.cnblogs.com/zishang91/p/8909900.html

https://segmentfault.com/a/1190000011007043

config/index.js

技术分享图片
proxyTable: {
      ‘/api‘:{ // 配置所有以api开头的请求路径
      target: ‘http://localhost:4000‘, // 代理目标的基础路径
      changeOrigin: true, //支持跨域
      pathRewrite: {
        ‘^/api‘: ‘‘
      }
      }
    },
View Code
