重写B站(网页、后端、小程序)

1. 网页端

       1.1 框架 

            Vue + Element+UI + axios

        1.2 框架搭建步骤

搭建Vue             

        1.3 配置文件 main.js

        

import {createApp} from 'vue'
import ElementUi from 'element-plus'
import 'element-plus/dist/index.css';
import axios from "axios";
import router from './router'
import App from './App'const app = createApp(App)
app.use(ElementUi)
app.use(router)
app.config.globalProperties.$http = axios
app.config.globalProperties.$axios = axiosapp.mount('#app');

       1.4 配置路由 

                        1.4.1 添加 依赖 

npm install vue-router@4

import { createRouter, createWebHistory } from 'vue-router';import Home from '@/views/page/page';const routes = [{ path: '/page', component: Home }];const router = createRouter({history: createWebHistory(),routes});export default router;

                1.4.2 注意Vue 的钩子函数触发事件

        

                1.4.3 核心钩子

                        created : 首次进入刷新、一般进行首次的页面数据加载

                        mounted ： 数据发生变更之后、重新加载

                        

2. 后端

        2.1 框架

                2.1.1 语言： JAVA

                2.2.2 开发框架 ：

                        SpringBoot 2.0  、Spring cloud Finchley.SR1

        2.2 微服务

                2.2.1 结构

                            2.2.2 框架搭建步骤

2.3 微服务节点配置

        2.3.1 BlMan (父节点)

                2.3.1.1 blMan parent 父节点 POM 配置

3. 小程序端 

        3.1 框架

                3.1.1 微信小程序、vantWeb

                3.1.2 创建小程序项目 （appId 在 微信小程序官网申请，不使用云服务开发）          

                3.1.3 默认页面

                3.1.4 引入 vant-webapp ui 包

                npm i @vant/weapp

---

上诉前端、手机端、后端框架搭建完成、开始页面编写。。。

4. vue 前端页面 布局、手机端页面布局

        4.1 页面设计开发

                4.1.1 首页

                        4.1.1.1 整体布局

                        4.1.1.2 采用 element-ui 重写

                                4.1.1.2.1 宏观布局

                        

4.1.1.2.2 导航栏设计

设计思路：这块内容处于整体页面正上方、width为100%、铺满上方

 UI代码要点：          

el-container 整体布局、el-header 表示当前元素处于上方
导航栏 使用 el-menu 设置
子元素 el-menu-item (单菜单、可依据router跳转) 、el-submenu (二级下拉菜单)

4.1.1.3 小程序首页大致布局设计

        最终效果：

        

        index.wxml

<scroll-view scroll-x="true" class="main_tb"><view class="head_title"><view>头像</view><view>搜索</view><view>游戏</view><view>消息</view></view><view class="head_nav" style="top: {{top}};"><view class="head_nav_title"><van-tabs  active="{{ active }}" line-width="0" ellipsis><van-tab wx:for="{{title_menu}}" wx:for-index="index" wx:for-item="title_"   title="{{title_.title_name}}"></van-tab></van-tabs></view><view class="head_nav_mark"></view><view class="head_nav_fixed">固定</view></view><view class="recommend">3</view><view class="vedio_main"><view class="vedio_main_one"></view><view class="vedio_main_one"></view><view class="vedio_main_one"></view><view class="vedio_main_one"></view></view></scroll-view>

        index.wxss

.main_tb {display: flex;justify-content: space-between;/* 竖向排列 */flex-direction: column;
}.head_title {height: 80rpx;background-color: red;display: flex;justify-content: space-between;align-items: center;
}.head_nav {height: 80rpx;background-color: rosybrown;display: flex;justify-content: start;flex-direction: row;align-items: center;position:fixed;
}.head_nav_title {width: 90%;height: 80rpx;
}.head_nav_fixed {width: 10%;height: 80rpx;position: fixed;
}
.head_nav_mark {width: 10%;height: 80rpx;
}.recommend {height: 400rpx;background-color: royalblue;margin: 30rpx;
}.vedio_main  {display: flex;justify-content:space-around;flex-direction: row;flex-wrap: wrap;
}.vedio_main .vedio_main_one {background-color: cadetblue;height: 300rpx;width: 45%;margin-top: 20rpx;
}

        index.json

{"usingComponents": {"van-tab": "@vant/weapp/tab/index","van-tabs": "@vant/weapp/tabs/index"},"enablePullDownRefresh": true,"onReachBottomDistance": 0
}

        index.js

Page({data: {title_menu : [{title_code : 1,title_name : "直播"},{title_code : 2,title_name : "推荐"},{title_code : 3,title_name : "热门"},{title_code : 4,title_name : "动画"},{title_code : 5,title_name : "动画"},{title_code : 6,title_name : "动画"},{title_code : 7,title_name : "动画"},{title_code : 9,title_name : "动画"},{title_code : 10,title_name : "动画"},{title_code : 11,title_name : "动画"}],active : 2,top: "100rpx",},onPullDownRefresh() {console.log('触发了上拉刷新事件')this.setData({top:"100rpx"})},onReachBottom() {if(this.data.top !== 0) {this.setData({top:0})console.log("触底事件触发")}},  
})

        app.json 主配置文、包含一些tabbar(最下面的标签)、新增的一些页面

        标签获取网站 https://www.iconfont.cn/

{"pages": ["pages/index/index","pages/dynamic/dynamic","pages/publish/publish","pages/vip_shop/vip_shop","pages/mine/mine","pages/logs/logs"],"window": {"navigationBarTextStyle": "black","navigationBarTitleText": "Weixin","navigationBarBackgroundColor": "#ffffff"},"componentFramework": "glass-easel","sitemapLocation": "sitemap.json","lazyCodeLoading": "requiredComponents","usingComponents": {},"tabBar": {"list": [{"pagePath": "pages/index/index","text": "首页","iconPath": "./image/HOME.png","selectedIconPath": "./image/home_seleced.png"},{"pagePath": "pages/dynamic/dynamic","text": "动态","iconPath": "./image/miss_page_icon/fengche.png","selectedIconPath": "./image/selected_page_icon/fengche.png"},{"pagePath": "pages/publish/publish","text": "发布","iconPath": "./image/miss_page_icon/publish.png","selectedIconPath": "./image/selected_page_icon/publish.png"},{"pagePath": "pages/vip_shop/vip_shop","text": "会员购","iconPath": "./image/miss_page_icon/gouwubao.png","selectedIconPath": "./image/selected_page_icon/gouwubao.png"},{"pagePath": "pages/mine/mine","text": "我的","iconPath": "./image/miss_page_icon/dianshi.png","selectedIconPath": "./image/selected_page_icon/dianshi.png"}]}
}
