1 吐槽列表与详细页
1.1 吐槽列表页
1.1.1 吐槽列表页数据渲染
吐槽列表页已经构建，我们现在来实现数据的渲染
（1）easyMock模拟数据
URL: spit/spit/search/{page}/{size}
Method: post
{"code": 20000,"flag": true,"message": "查询成功","data": {"total": "@integer(60, 100)","rows|10": [{"id": "@string","content": "@cword(100,300)","publishtime": "@datetime","userid": "@string","nickname": "小雅","visits": "@integer(60, 100)","thumbup": "@integer(60, 100)","share": "@integer(60, 100)","comment": "@integer(60, 100)","state": "@string","parentid": "@string"}]}
}
（2）api目录下创建spit.js
import request from '@/utils/request'
const group_name = 'spit'
const api_name = 'spit'
export default {search(page, size, searchMap) {return request({url: `/${group_name}/${api_name}/search/${page}/${size}`,method: 'post',data: searchMap})}
}
（3）修改pages/spit/index.vue
<template><div><div class="wrapper tag-item"> <div class="fl left-list"> <div class="tc-data-list"> <div class="tc-list"> <ul class="detail-list"> <li class="qa-item" v-for="(item,index) in items" :key="index"> <div class="fl record"> <div class="number"> <div class="border useful"> <p class="usenum"><a href="#" class="zan"><i class="fa fa-thumbs-up " aria-hidden="true"></i></a></p> <p class="zannum"> {{item.thumbup}} </p> </div> <div class="border answer"> <a href="#" class="star"><i class="fa fa-star-o" aria-hidden="true"></i></a> </div> </div> </div> <div class="info"> <p class="text"> <a href="~/assets/spit-detail.html" target="_blank"> {{item.content}} </a> </p> <div class="other"> <div class="fl date"> <span>{{item.publishtime}}</span> </div> <div class="fr remark"> <a href="#" data-toggle="modal" data-target="#shareModal" class="share"><i class="fa fa-share-alt" aria-hidden="true"></i> 分享</a> <a href="#" data-toggle="modal" data-target="#remarkModal" class="comment"><i class="fa fa-commenting" aria-hidden="true"></i> 回复</a> </div> </div> </div> <div class="clearfix"></div> </li> </ul> <div class="modal fade" id="shareModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">分享到</h4> </div> <div class="modal-body" style="overflow:hidden"> <div class="jiathis_style_32x32"> <a class="jiathis_button_qzone"></a> <a class="jiathis_button_tsina"></a> <a class="jiathis_button_weixin"></a> <a class="jiathis_button_cqq"></a> </div> </div> </div> </div> </div> <div class="modal fade" id="remarkModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">发表评论</h4> </div> <div class="modal-body"> <div class="comment"> <span class="who"><img src="~/assets/img/asset-photo.png" />匿名评论</span>: 今天入职腾讯，产品岗，普通非985211大学，上家是不到五十人创业小公司！16年毕业！找内推腾讯给的面试机会，五轮面试！可能是我把运气攒一起了！ </div> <div class="form"> <textarea class="form-control" rows="5" placeholder="匿名评论"></textarea> <div class="remark"> <button class="sui-btn btn-info">发表</button> </div> </div> </div> </div> </div> </div> </div> </div> </div> <div class="fl right-tag"> <div class="block-btn"> <p>来个匿名吐槽，发泄一下你心中的怒火吧！</p> <a class="sui-btn btn-block btn-share" href="~/assets/spit-submit.html" target="_blank">发吐槽</a> </div> </div> <div class="clearfix"></div> </div></div>
</template>
<script>
import '~/assets/css/page-sj-spit-index.css'
import spitApi from '@/api/spit'
export default {asyncData(){return spitApi.search(1,10, {state:'1'} ).then( res=> {return {items:res.data.data.rows}})}
}
</script>
1.1.2 吐槽列表瀑布流
修改页面pages/spit/index.vue
<div class="tc-list" v-infinite-scroll="loadMore" >
修改pages/spit/index.vue ,添加pageNo用于记录页码 增加方法
data(){return {pageNo: 1}},methods:{loadMore(){this.pageNo++ spitApi.search( this.pageNo,10,{state:'1'} ).then( res=>{this.items=this.items.concat( res.data.data.rows )})}}
1.2 吐槽详情页
1.2.1 构建吐槽详情页
（1）根据spit-detail.html创建pages/spit/_id.vue ，内容略
（2）修改pages/spit/index.vue 页面链接
<router-link :to="'/spit/'+item.id"> {{item.content}} </router-link>
1.2.2 吐槽详情页数据渲染
（1）easyMock模拟数据
URL: spit/spit/{id}
Methos: GET
{"code": 20000,"flag": true,"message": "@string","data": {"id": "@string","nikename": "小雅","content": "@cword(100,300)","publishtime": "@datetime","thumbup": "@integer(60, 100)","share": "@integer(60, 100)","comment": "@integer(60, 100)"}
}
URL: spit/spit/commentlist/{id}
Method: GET
{"code": 20000,"flag": true,"message": "@string","data|10": [{"id": "@string","content": "我要评论我要评论我要评论我要评论我要评论我要评论","nikename": "小雅","publishtime": "@datetime","thumbup": "@integer(60, 100)"}]
}
（2）修改api/spit.js
findById(id){return request({url: `/${api_group}/${api_name}/${id}`,method: 'get'})},commentlist(id){return request({url: `/${api_group}/${api_name}/commentlist/${id}`,method: 'get'})}（3）修改pages/spit/_id.vue
<template><div class="wrapper tc-detail"> <div class="fl left-list"> <div class="tc-detail"> <!-- 标题区 --> <div class="detail-tit"> <div class="detail-author"> <a href="javascript:;">{{pojo.nickname}}</a> 发布 </div> <div class="detail-content"> <p>{{pojo.content}}</p> </div> <div class="detail-tool"> <ul> <li><span class="star"><i class="fa fa-thumbs-o-up" aria-hidden="true"></i> {{pojo.thumbup}}</span></li> <li><a href="#" data-toggle="modal" data-target="#shareModal"><i class="fa fa-share-alt" aria-hidden="true"></i> {{pojo.share}}</a></li> <li><a data-toggle="modal" data-target="#remarkModal"><i class="fa fa-commenting" aria-hidden="true"></i> {{pojo.comment}}</a></li> </ul> </div> </div> <!-- 评论区 --> <div class="comment-area"> <div class="comment-tit"> <span>评论</span> </div> <ul class="comment-list"> <li v-for="(item,index) in commentlist" :key="index"> <div class="item-photo"> <img src="~/assets/img/widget-widget-photo.png" alt="" /> </div> <div class="item-content"> <p class="author"><a href="javascript:;">{{item.nickname}}</a> 发布</p> <p class="content">{{item.content}}</p> </div> <div class="item-thumb"> <div><i class="fa fa-thumbs-o-up" aria-hidden="true"></i> {{item.thumbup}}</div> </div> </li> </ul> </div> </div> </div> <div class="fl right-tag"> <div class="block-btn"> <p>来个匿名吐槽，发泄一下你心中的怒火吧！</p> <a class="sui-btn btn-block btn-share" href="~/assets/spit-submit.html" target="_blank">发吐槽</a> </div> </div> <div class="clearfix"></div> </div>
</template>
<script>
import '~/assets/css/page-sj-spit-detail.css'
import spitApi from '@/api/spit'
import axios from 'axios'
export default {asyncData({params}){return axios.all( [ spitApi.findById(params.id),spitApi.commentlist(params.id) ] ).then( axios.spread( function( pojo,commentlist ){return {pojo: pojo.data.data,commentlist: commentlist.data.data} }))}
}
</script>1.3 吐槽点赞
1.3.1 基本功能
（1）easyMock模拟数据
URL: spit/spit/thumbup/{id}
Method: put
{"code": 20000,"flag": true,"message": "执行成功"
}（2）api/spit.js 增加方法
thumbup(id) {return request({url: `/${api_group}/${api_name}/thumbup/${id}`,method: 'put'})}（3）修改pages/spit/index.vue
methods: {thumbup(index){spitApi.thumbup(this.items[index].id).then( res=>{if(res.data.flag){this.items[index].thumbup++}})}}（4）点赞调用
<p class="usenum" @click="thumbup(index)"><a href="#" class="zan"><i class="fa fa-thumbs-up " aria-hidden="true"></i></a></p> 1.3.2 样式处理
实现点赞后，大拇指图标变色。样式表已经写好，在li 的样式上加上color 即可
（1）修改pages/spit/index.vue 的代码部分
import '~/assets/css/page-sj-spit-index.css'
import spitApi from '@/api/spit'
export default {asyncData(){return spitApi.search(1,10, {state:'1'} ).then( res=> {let tmp= res.data.data.rows.map( item=>{return {...item,zan: ''}})return {items:tmp}})},data(){return {pageNo: 1}},methods:{loadMore(){this.pageNo++ spitApi.search( this.pageNo,10,{state:'1'} ).then( res=>{let tmp= res.data.data.rows.map( item=>{return {...item,zan: ''}})this.items=this.items.concat( tmp )})},thumbup(index){this.items[index].zan='color'spitApi.thumbup(this.items[index].id).then( res=>{if(res.data.flag){this.items[index].thumbup++}})}}
}（2）修改pages/spit/index.vue的html部分
<a href="#" class="zan"><i :class="'fa fa-thumbs-up '+item.zan" aria-hidden="true"></i>
</a>1.3.3 判断是否登陆
要求：点赞必须要在用户登陆的情况下执行，非登陆状态下不能点赞。并且不可重复点赞
导入getUser
import {getUser} from '@/utils/auth'修改thumbup（点赞）方法
thumbup(index){if(getUser().name===undefined){this.$message({message:'必须登陆才可以点赞哦~',type:"warning"})return }if( this.items[index].zan==='color'){this.$message({message:'不可以重复点赞哦~',type:"warning"})return }this.items[index].zan='color'spitApi.thumbup(this.items[index].id).then( res=>{if(res.data.flag){this.items[index].thumbup++}})}1.3.4 提交token
修改utils/request.js ,每次请求将token添加到header里
import axios from 'axios'
import {getUser} from '@/utils/auth'
// 创建axios实例
const service = axios.create({baseURL: 'http://192.168.184.133:7300/mock/5af314a4c612520d0d7650c7', // api的base_urltimeout: 30000, // 请求超时时间headers: { 'Authorization': 'Bearer '+getUser().token }})
export default service2 发吐槽与吐槽评论
2.1 发吐槽
2.1.1 构建页面
我们这里用到VUE常用的富文本编辑器vue-quill-editor
详见文档： https://www.npmjs.com/package/vue-quill-editor
（1）安装vue-quill-editor
cnpm install vue-quill-editor --save（2）plugins下创建nuxt-quill-plugin.js
import Vue from 'vue'
import VueQuillEditor from 'vue-quill-editor/dist/ssr'
Vue.use(VueQuillEditor)（3）修改nuxt.config.js ,配置插件和样式
plugins: [{ src: '~plugins/nuxt-quill-plugin.js', ssr: false }],// some nuxt config...css: ['quill/dist/quill.snow.css','quill/dist/quill.bubble.css','quill/dist/quill.core.css'],（4）pages/spit/submit.vue
<template><div class="wrapper release-tc"> <div class="release-box"> <h3>发布吐槽</h3> <div class="editor"> <div class="quill-editor" :content="content"@change="onEditorChange($event)"@blur="onEditorBlur($event)"@focus="onEditorFocus($event)"@ready="onEditorReady($event)"v-quill:myQuillEditor="editorOption"></div><div class="btns"> <button class="sui-btn btn-danger btn-release">发布</button> </div> <div class="clearfix"></div> </div> </div> <div class="clearfix"></div> </div> </template>
<script>
import '~/assets/css/page-sj-spit-submit.css'export default {data () {return {content: '',editorOption: {// some quill optionsmodules: {toolbar: [[{ 'size': ['small', false, 'large'] }],['bold', 'italic'],[{ 'list': 'ordered'}, { 'list': 'bullet' }],['link', 'image']]}}}},mounted() {console.log('app init, my quill insrance object is:', this.myQuillEditor)/*setTimeout(() => {this.content = 'i am changed'}, 3000)*/},methods: {onEditorBlur(editor) {console.log('editor blur!', editor)},onEditorFocus(editor) {console.log('editor focus!', editor)},onEditorReady(editor) {console.log('editor ready!', editor)},onEditorChange({ editor, html, text }) {console.log('editor change!', editor, html, text)this.content = html}}}
</script>
<style>
.quill-editor {min-height: 200px;max-height: 400px;overflow-y: auto;}</style>（5）修改pages/spit/index.vue 链接到此页面
<router-link class="sui-btn btn-block btn-share" to="/spit/submit">发吐槽</router-link>2.1.2 提交吐槽
（1）easyMock模拟数据
URL:spit/spit
Method: post
{"code": 20000,"flag": true,"message": "执行成功"
}（2）修改api/spit.js ，增加提交吐槽的方法
save(pojo) {return request({url: `/${group_name}/${api_name}`,method: 'post',data: pojo})}（2）修改pages/spit/submit.vue 引入API
import spitApi from '@/api/spit'在methods增加方法
save(){spitApi.save({ content:this.content } ).then(res=>{this.$message({message: res.data.message,type: (res.data.flag?'success':'error')})if(res.data.flag){this.$router.push('/spit')}})}$router.push()的作用是路由跳转。
（3）发布按钮调用方法
<button class="sui-btn btn-danger btn-release" @click="save">发布</button> 2.2 吐槽评论
2.2.1 评论弹出框
我们这里的评论弹出框使用elementUI的弹出框来实现
（1）修改pages/spit/_id.vue ,添加弹出框, 弹出框中放置富文本编辑器
<el-dialogtitle="评论":visible.sync="dialogVisible"width="40%" ><div class="quill-editor" :content="content"@change="onEditorChange($event)"v-quill:myQuillEditor="editorOption"></div> <span slot="footer" class="dialog-footer"><el-button @click="dialogVisible = false">取 消</el-button><el-button type="primary" @click="dialogVisible = false">确 定</el-button></span></el-dialog>为富文本编辑框添加样式：
<style>
.quill-editor {min-height: 200px;max-height: 400px;overflow-y: auto;}
</style>（2）修改pages/spit/index.vue代码部分
data(){return {dialogVisible: false,content: '',editorOption: {// some quill optionsmodules: {toolbar: [[{ 'size': ['small', false, 'large'] }],['bold', 'italic'],[{ 'list': 'ordered'}, { 'list': 'bullet' }],['link', 'image']]}}}},methods:{onEditorChange({ editor, html, text }) {console.log('editor change!', editor, html, text)this.content = html}}（3）修改pages/spit/_id.vue 中的回复链接
<a @click="dialogVisible=true;content=''"><i class="fa fa-commenting" aria-hidden="true"></i> {{pojo.comment}}</a>2.2.2 提交评论
修改pages/spit/_id.vue ，增加提交回复的方法
save(){spitApi.save({ content:this.content,parentid: this.pojo.id } ).then(res=>{this.$message({message: res.data.message,type: (res.data.flag?'success':'error')})if(res.data.flag){this.dialogVisible=falsespitApi.commentlist(this.pojo.id).then(res=>{this.commentlist=res.data.data})}})}编辑提交按钮
<el-button type="primary" @click="save">提交</el-button>3 问答频道
3.1 嵌套布局与标签导航
3.1.1 嵌套布局
（1）创建pages/qa.vue

4 图片上传
4.1 Data URL
Data URL给了我们一种很巧妙的将图片“嵌入”到HTML中的方法。跟传统的用img标记将服务器上的图片引用到页面中的方式不一样，在Data URL协议中，图片被转换成base64编码的字符串形式，并存储在URL中，冠以mime-type。
传统方式：
<img src="data:images/myimg.gif ">这种方式中，img标记的src属性指定了一个远程服务器上的资源。当网页加载到浏览器中 时，浏览器会针对每个外部资源都向服务器发送一次拉取资源请求，占用网络资源。大多数的浏览器都有一个并发请求数不能超过4个的限制。这意味着，如果一个 网页里嵌入了过多的外部资源，这些请求会导致整个页面的加载延迟。而使用Data URL技术，图片数据以base64字符串格式嵌入到了页面中，与HTML成为一体，它的形式如下

URL方式。
4.2 辅助插件vue-quill-editor-upload
如果你不想使用Data URL方式存储图片，我们可以通过一个辅助插件vue-quill-editor-upload 来让vue-quill-editor实现传统方式的上传。
（1）安装：
cnpm install vue-quill-editor-upload --save（2）修改submit.vue 引入插件
import {quillRedefine} from 'vue-quill-editor-upload'（3）将editorOption的值改为{}
data () {return {content: '',editorOption:{}//修改此处！}}（4）新增created 钩子函数
created () {this.editorOption = quillRedefine({// 图片上传的设置uploadConfig: {action: 'http://localhost:3000/upload', // 必填参数 图片上传地址// 必选参数 res是一个函数，函数接收的response为上传成功时服务器返回的数据// 你必须把返回的数据中所包含的图片地址 return 回去res: (respnse) => {return respnse.info},name: 'img' // 图片上传参数名}})}4.3 Multer（了解）
课程中提供了上传图片的服务端代码 upload-server ，我们可以先测试运行后，对照在线文档阅读并理解代码（课程不要求学员独立编写此段代码）
cnpm install
npm run start 这段代码主要应用两项技术：
（1）Express --node.js的web框架 在线文档： http://www.expressjs.com.cn/4x/api.html
（2）Multer --Express官方推出的，用于multipart/form-data请求数据处理的中间件 在线文档： https://github.com/expressjs/multer/blob/master/doc/README-zh-cn.md
4.4 云存储解决方案-阿里云OSS
为了能够解决海量数据存储与弹性扩容，我们在十次方项目中采用云存储的解决方案- 阿里云OSS。
4.4.1 准备工作
（1）申请阿里云账号并完成实名认证： 可以使用我们之前发短信用的阿里云账号。
（2）开通OSS: 登录阿里云官网。将鼠标移至产品找到并单击对象存储OSS打开OSS产品详情页面。在OSS产品详情页中的单击立即开通。开通服务后，在OSS产品详情页面单击管理控制台直接进入OSS管理控制台界面。您也可以单击位于官网首页右上方菜单栏的控制台，进入阿里云管理控制台首页，然后单击左侧的对象存储OSS菜单进入OSS管理控制台界面。
（3）创建存储空间
新建Bucket，命名为tensquare ，读写权限为公共读
4.4.2 代码编写
（1）安装ali-oss
cnpm install ali-oss --save
cnpm install co --save（2）修改file-upload-demo-master的server.js
var co = require('co');
var OSS = require('ali-oss');
var client = new OSS({accessKeyId: 'LTAIWaEERTRWSD2',accessKeySecret: 'PznrHXxYvTcADAFFDDDJnoAokJ0NSWEWF',endpoint: 'oss-cn-beijing.aliyuncs.com',bucket: 'tensquare'
