小编目前在做毕业设计，主题为“高考志愿信息交流平台”，面向高中生和大学生，辛苦各位读者大佬朋友们填下问卷，点击链接https://www.wjx.cn/jq/98944127.aspx或扫描二维码、微信小程序码均可，希望各位能提供一些调查数据，先在这里谢过各位了(*^_^*)
前言
本文先介绍了搜索结果页开发，包括搜索类型的传递、占位符设置和搜索功能实现；
再介绍了帖子详情页的开发，包括页面配置和通信、公共列表组件优化、关注顶踩功能完善、帖子内容和图片展示、评论输入框组件开发和封装、评论列表组件和分享功能组件开发等。
一、搜索列表页开发
首页有搜索帖子、动态页有搜索话题、消息页有搜索用户，因此需要实现搜索页。
1.搜索类型传递和占位符设置
不同页面的搜索类型不同，需要通过标识进行区别，index.vue如下：
// 监听导航栏搜索框
onNavigationBarSearchInputClicked() {
uni.navigateTo({
url: '../search/search?type=post'
})
},
news.vue如下：
<view class="p-2">
<view class="bg-light rounded flex align-center justify-center py-2 text-secondry" @click="openSearch()">
<text class="iconfont icon-sousuo mr-2">text>搜索话题
view>
view>
// 打开搜索页
openSearch() {
uni.navigateTo({
url: '../search/search?type=topic'
});
}
user-list.vue如下：
// 监听点击输入框事件
onNavigationBarSearchInputClicked() {
uni.navigateTo({
url: '../search/search?type=user'
});
},
msg.vue如下：
// 弹出层选项点击事件
popupEvent(e) {
switch (e) {
case 'friend':
console.log('Adding friend');
uni.navigateTo({
url: '../search/search?type=user'
});
break;
case 'clear':
console.log('Clearing list');
break;
default:
break;
}
// 关闭弹出层
this.$refs.popup.close();
}
search.vue完善搜索类型和占位符，如下：
<template>
<view>
<template v-if="searchList.length === 0">
<view class="py-2 font-md px-2">搜索历史view>
<view class="flex flex-wrap">
<view class="border rounded font mx-2 my-1 px-2" hover-class="bg-light" v-for="(item, index) in list" :key="index"
@click="clickSearchHistory(item)">{
{item}}view>
view>
template>
<template v-else>
<block v-for="(item, index) in searchList" :key="index">
<common-list :item="item" :index="index">common-list>
block>
template>
view>
template>

其中，$getAppWebview()是用来获取当前webview的对象实例，从而可以实现对 webview 更强大的控制，这里是用来根据搜索类型改变导航栏搜索框占位符的。
显示：
可以看到，根据不同的搜索类型显示了不同的占位符placeholder。
2.搜索功能实现
需要根据不同的搜索类型搜索不同的内容，search.vue如下：
<template>
<view>
<template v-if="searchList.length === 0">
<view class="py-2 font-md px-2">搜索历史view>
<view class="flex flex-wrap">
<view class="border rounded font mx-2 my-1 px-2" hover-class="bg-light" v-for="(item, index) in list" :key="index"
@click="clickSearchHistory(item)">{
{item}}view>
view>
template>
<template v-else>
<block v-for="(item, index) in searchList" :key="index">
<template v-if="type === 'post'">
<common-list :item="item" :index="index" :key="'user'+index">common-list>
template>
<template v-else-if="type === 'topic'">
<topic-list :item="item" :index="index" :key="'user'+index">topic-list>
template>
<template v-else>
<user-list :item="item" :index="index" :key="'user'+index">user-list>
template>
block>

searchText: '',
// 搜索结果
searchList: [],
// 当前搜索类型
type: 'post'
}
},
components: {
commonList,
topicList,

},
// 监听导航栏搜索框输入

console.log(e);
this.searchText = e.text;

pageTitle = '用户'
break;
default:
break;
}
// 修改搜索占位
// #ifdef APP-PLUS
let currentWebview = this.$scope.$getAppWebview(); // 当前窗口实例
let tn = currentWebview.getStyle().titleNView; // 当前窗口原生导航栏
tn.searchInput.placeholder = '搜索' + pageTitle; // 修改placeholder

clickSearchHistory(text) {
this.searchText = text;
this.searchEvent();
}
}
}
script>
<style>
style>
显示：
可以看到，实现了根据不同的搜索类型显示不同的搜索内容。
二、帖子详情页开发
1.pages.json配置和页面通信
先新建帖子详情页detail.vue，再在pages.json中配置页面右上角的菜单按钮，如下：
{
"path" : "pages/detail/detail",
"style" :
{
"navigationBarTitleText": "",
"enablePullDownRefresh": false,
"app-plus": {
"titleNView": {
"buttons": [
{
"type":"menu",
"float":"right"
}
]
}
}
}
}
帖子详情页一般从common-list组件进入，如下：
// 进入详情页
openDetail() {
uni.navigateTo({
url: '../../pages/detail/detail?detail='+JSON.stringify(this.item),
});
},
detail.vue修改如下：
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title:data.title
});
// 请求API
}
}
显示：
可以看到，页面的标题显示的是帖子的标题。
2.公共列表组件功能优化
对公共列表组件功能进行优化，以使其可以兼容到帖子详情页头部，此时传的属性值增加一个值isdetail用来判断是否是详情页，同时添加插槽用来插入帖子内容，common-list.vue如下：
<template>
<view class="p-2">
<view class="flex align-center justify-between">
<view class="flex align-center">
<image class="rounded-circle mr-2" :src="item.userpic" mode="" style="width: 65rpx; height: 65rpx;" @click="openSpace"
lazy-load>image>
<view>
<view class="font" style="line-height: 1.5;">{
{item.username}}view>
<text class="font-sm text-light-muted" style="line-height: 1.5;">{
{item.newstime}}text>
view>
view>
<view v-if="!item.isFollow" class="flex align-center justify-center rounded bg-main text-white animate__animated animate__faster"
hover-class="animate__jello" style="width: 90rpx; height: 50rpx;" @click="follow">
关注
view>
view>
<view class="font my-1" @click="openDetail">
{
{item.title}}
view>
<slot>
<image v-if="item.titlepic" class="rounded w-100" :src="item.titlepic" style="height: 350rpx;" @click="openDetail">image>
slot>
<view class="flex align-center">
<view class="flex align-center justify-center flex-1 animate__animated animate__faster" hover-class="animate__jello text-main"
@click="doSupport('support')" :class="item.support.type === 'support' ? 'support-active' : ''">
<text class="iconfont icon-dianzan mr-2">text>
<text>{
{item.support.support_count > 0 ? item.support.support_count : '支持'}}text>
view>
<view class="flex align-center justify-center flex-1 animate__animated animate__faster" hover-class="animate__jello text-main"
@click="doSupport('unsupport')" :class="item.support.type === 'unsupport' ? 'support-active' : ''">
<text class="iconfont icon-cai mr-2">text>
<text>{
{item.support.unsupport_count > 0 ? item.support.unsupport_count : '反对'}}text>
view>
<view class="flex align-center justify-center flex-1 animate__animated animate__faster" hover-class="animate__jello text-main"
@click="openDetail">
<text class="iconfont icon-pinglun mr-2">text>
<text>{
{item.comment_count > 0 ? item.comment_count : '评论'}}text>
view>
<view class="flex align-center justify-center flex-1 animate__animated animate__faster" hover-class="animate__jello text-main"
@click="openDetail">
<text class="iconfont icon-fenxiang mr-2">text>
<text>{
{item.share_count > 0 ? item.share_count : '分享'}}text>
view>
view>
view>
template>
<script>
export default {
props: {
item: Object,
index: Number,
isdetail: {
type: Boolean,
default: false
}
},
methods: {
// 打开个人空间
openSpace() {
console.log('Space opened');
},
// 关注
follow() {
console.log('Followed');
// 通知父组件
this.$emit('follow', this.index);
},
// 进入详情页
openDetail() {
// 处于详情页
if (this.isdetail) return;
uni.navigateTo({
url: '../../pages/detail/detail?detail='+JSON.stringify(this.item),
});
},
// 顶踩操作
doSupport(type) {
console.log(type);
// 通知父组件
this.$emit('doSupport', {
type,
index: this.index
})
}
}
}
script>
<style>
.support-active {
color: #FF4A6A;
}
style>
detail.vue如下：
<template>
<view>
<common-list :item="info" isdetail>
帖子详情
common-list>
view>
template>
<script>
import commonList from '@/components/common/common-list.vue';
export default {
data() {
return {
// 当前帖子信息
info: {
}
}
},
components: {
commonList
},
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title: data.title
});
// 请求API
this.info = data;
}
}
}
script>
<style>
style>
显示：
可以看到，实现了common-list组件的复用。
再给评论和分享按钮添加点击事件，如下：
<template>
<view class="p-2">
<view class="flex align-center justify-between">
<view class="flex align-center">
<image class="rounded-circle mr-2" :src="item.userpic" mode="" style="width: 65rpx; height: 65rpx;" @click="openSpace"
lazy-load>image>
<view>
<view class="font" style="line-height: 1.5;">{
{item.username}}view>
<text class="font-sm text-light-muted" style="line-height: 1.5;">{
{item.newstime}}text>
view>
view>
<view v-if="!item.isFollow" class="flex align-center justify-center rounded bg-main text-white animate__animated animate__faster"
hover-class="animate__jello" style="width: 90rpx; height: 50rpx;" @click="follow">
关注
view>
view>
<view class="font my-1" @click="openDetail">
{
{item.title}}

}
this.$emit('doShare');
}
}
}
script>
<style>
.support-active {
color: #FF4A6A;
}
style>
detail.vue如下：
<template>
<view>
<common-list :item="info" isdetail @doComment="doComment" @doShare="doShare">
帖子详情
common-list>
view>
template>
<script>
import commonList from '@/components/common/common-list.vue';
export default {
data() {
return {
// 当前帖子信息
info: {
}
}
},
components: {
commonList
},
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title: data.title
});
// 请求API
this.info = data;
},
// 点击评论
doComment() {
console.log('Commenting...');
},
// 点击分享
doShare() {
console.log('Sharing...');
}
}
}
script>
<style>
style>
显示：
可以看到，在贴子列表页点击评论和分享按钮时进入帖子详情页，在帖子详情页点击时会触发评论和分享事件。
3.详情页关注和顶踩功能完善
在详情页实现关注和顶踩功能，如下：
<template>
<view>
<common-list :item="info" isdetail @doComment="doComment" @doShare="doShare" @follow="follow" @doSupport="doSupport">
帖子详情
common-list>
view>
template>
<script>
import commonList from '@/components/common/common-list.vue';
export default {
data() {
return {
// 当前帖子信息
info: {
}
}
},
components: {
commonList
},
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title: data.title
});
// 请求API
this.info = data;
},
// 关注
follow() {
this.info.isFollow = true;
uni.showToast({
title: '关注成功'
});
},
// 顶踩操作
doSupport(e) {
let msg = e.type === 'support' ? '顶' : '踩';
// 之前操作过
if(this.info.support.type === e.type) {
return uni.showToast({
title: '您已经' + msg + '过了'
});
}
// 之前未操作过
if(this.info.support.type === '') {
this.info.support[e.type + '_count']++;
}
// 之前已顶过并且现在的操作为踩，则顶-1、踩+1
else if(this.info.support.type === 'support' && e.type === 'unsupport') {
this.info.support.support_count--;
this.info.support.unsupport_count++;
}
// 之前已踩过并且现在的操作为顶，则踩-1、顶+1
else if(this.info.support.type === 'unsupport' && e.type === 'support') {
this.info.support.unsupport_count--;
this.info.support.support_count++;
}
this.info.support.type = e.type;
uni.showToast({
title: msg + '成功'
});
},
// 点击评论
doComment() {
console.log('Commenting...');
},
// 点击分享
doShare() {
console.log('Sharing...');
}
}
}
script>
<style>
style>
index.vue如下：
// 切换选项
changeTab(index) {
if (this.tabIndex === index) {
return;
}
this.tabIndex = index;
this.list = this.newsList[this.tabIndex].list;
// 滚动到指定元素
this.scrollInto = 'tab' + index;
},
// 获取数据
getData() {
var arr = [];
for (let i = 0; i < this.tabBars.length; i++) {
// 生成列表模板
let obj = {
// 3种状态：1.上拉加载更多；2.加载中...；3.没有更多了。
loadmore: "上拉加载更多",
list: []
}
if (i % 3 !== 2) {
obj.list = test_data;
}
arr.push(obj)
}
this.newsList = arr;
this.list = this.newsList[this.tabIndex].list;
},
显示：
显然，已经实现了在首页和详情页进行关注和顶踩功能。
4.帖子内容和图片展示
给帖子数据增加content字段用于保存帖子内容、images字段（数组）用于保存图片，index.vue中测试数据如下：
// 测试数据
const test_data = [{
username: "Corley",
userpic: "/static/img/userpic/12.jpg",
newstime: "2021-01-24 上午11:30",
isFollow: false,
title: "uni-app入门教程",
titlepic: "/static/img/datapic/42.jpg",
support: {
type: "support", // 顶
support_count: 1,
unsupport_count: 2
},
comment_count: 2,
share_count: 2,
content: 'uni-app是DCloud官方推出的使用Vue.js开发跨平台应用的前端框架，一套代码可编译到iOS、Android、微信小程序等多个平台，学习和开发成本较低。在进行uni-app开发之前需要先搭建环境，下载并安装HBuilderX、微信开发者工具；新建项目时选择类型，创建之后会自动生成项目的默认目录，可以通过多种方式编译运行。一个典型的项目包括App.vue、main.js等文件和pages、static等目录；uni-app遵守Vue单文件组件规范，vue文件包括模板、脚本和样式3个顶级语言块。更多内容可点击https://blog.csdn.net/CUFEECR/article/details/111088889。',

<view>
<common-list :item="info" isdetail @doComment="doComment" @doShare="doShare" @follow="follow" @doSupport="doSupport">
<view>{
{info.content}}view>

template>
<script>
import commonList from '@/components/common/common-list.vue';
export default {
data() {
return {
// 当前帖子信息
info: {

}
},
components: {
commonList
},
computed: {
imagesList() {
return this.info.images.map(item=>item.url);
}
},
onLoad(e) {
console.log(e);
// 初始化操作

methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({

// 请求API
this.info = data;

// 关注
follow() {
this.info.isFollow = true;
uni.showToast({
title: '关注成功'
});
},
// 顶踩操作
doSupport(e) {
let msg = e.type === 'support' ? '顶' : '踩';
// 之前操作过
if(this.info.support.type === e.type) {
return uni.showToast({
title: '您已经' + msg + '过了'
});
}
// 之前未操作过
if(this.info.support.type === '') {
this.info.support[e.type + '_count']++;
}
// 之前已顶过并且现在的操作为踩，则顶-1、踩+1

this.info.support.support_count--;
this.info.support.unsupport_count++;

this.info.support.unsupport_count--;
this.info.support.support_count++;
}
this.info.support.type = e.type;
uni.showToast({

preview(index) {
uni.previewImage({

current: index
})
}
}
}
script>
<style>
style>
显示：
可以看到，显示了帖子内容，还可以预览图片。
5.评论输入框组件开发和封装
评论输入框和聊天页输入框类似，在components/common下新建组件bottom-input抽离底部输入框，如下：
<template>
<view style="height: 100rpx;" class="fixed-bottom flex align-center border-top bg-white">
<input type="text" v-model="content" value="" class="flex-1 rounded bg-light ml-2" style="padding: 5rpx 0;" placeholder="文明发言" @confirm="submit()" />
<view class="iconfont icon-fasong flex align-center justify-center font-lg animate__animated" hover-class="animate__jello text-main" style="width: 100rpx;" @click="submit()">view>
view>
template>
<script>
export default {
data() {
return {
content: ''
}
},
methods: {
submit() {
// 判断是否为空
if (this.content === ''){
return uni.showToast({
title: '消息不能为空',
icon: 'none'
});
}
this.$emit('submit', this.content);
// 清空输入框
this.content = '';
}
},
}
script>
<style>
style>
user-chat.vue如下：
<template>
<view>
<scroll-view scroll-y="true" style="position: absolute; left: 0; top: 0; right: 0; bottom: 100rpx;" :scroll-into-view="scrollInto" scroll-with-animation>
<block v-for="(item, index) in list">
<view :id="'chat'+index">
<user-chat-list :item="item" :index="index" :preTime="index > 0 ? list[index-1].create_time : 0">user-chat-list>
view>
block>
scroll-view>
<bottom-input @submit="submit">bottom-input>
view>
template>
<script>
import userChatList from '@/components/user-chat/user-chat-list.vue';
import bottomInput from '@/components/common/bottom-input.vue';
export default {
data() {
return {
list: [
{
user_id: 2,
username: 'Natalia',
avatar: '/static/img/userpic/14.jpg',
data: '大佬，你好',

user_id: 1,
username: 'Corley',
avatar: '/static/img/userpic/11.jpg',
data: '好的，我马上看',
type: 'text',
create_time: 1612157821
}
],
scrollInto: '',
username: ''
}
},
components: {
userChatList,
bottomInput
},
onLoad(e) {
console.log(e);
this.username = e.username;
},
// 页面加载完成
onReady() {
this.pageToBottom();
uni.setNavigationBarTitle({
title: this.username
});
},
methods: {
// 发送消息
submit(data) {
let obj = {
user_id: 1,
username: 'Corley',
avatar: '/static/img/userpic/11.jpg',
data: data,
type: 'text',
create_time: (new Date()).getTime()
}
this.list.push(obj);
// 滚动到底部
this.pageToBottom();
},
// 滚动到底部
pageToBottom() {
let lastIndex = this.list.length - 1;
if (lastIndex < 0) return;
this.scrollInto = 'chat' + lastIndex;
}
}
}
script>
<style>
style>
detail.vue如下：
<template>
<view>
<common-list :item="info" isdetail @doComment="doComment" @doShare="doShare" @follow="follow" @doSupport="doSupport">
<view>{
{info.content}}view>
<view class="">
<block v-for="(item, index) in info.images">

block>
view>
common-list>
<view style="height: 100rpx;">view>
<bottom-input @submit="submit">bottom-input>
view>
template>
<script>
import commonList from '@/components/common/common-list.vue';
import bottomInput from '@/components/common/bottom-input.vue';
export default {
data() {
return {
// 当前帖子信息
info: {
}
}
},
components: {
commonList,
bottomInput
},
computed: {
imagesList() {
return this.info.images.map(item=>item.url);
}
},
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title: data.title
});
// 请求API
this.info = data;
},
// 关注
follow() {
this.info.isFollow = true;
uni.showToast({
title: '关注成功'
});
},
// 顶踩操作
doSupport(e) {
let msg = e.type === 'support' ? '顶' : '踩';
// 之前操作过
if(this.info.support.type === e.type) {
return uni.showToast({
title: '您已经' + msg + '过了'
});
}
// 之前未操作过
if(this.info.support.type === '') {
this.info.support[e.type + '_count']++;
}
// 之前已顶过并且现在的操作为踩，则顶-1、踩+1
else if(this.info.support.type === 'support' && e.type === 'unsupport') {
this.info.support.support_count--;
this.info.support.unsupport_count++;
}
// 之前已踩过并且现在的操作为顶，则踩-1、顶+1
else if(this.info.support.type === 'unsupport' && e.type === 'support') {
this.info.support.unsupport_count--;
this.info.support.support_count++;
}
this.info.support.type = e.type;
uni.showToast({
title: msg + '成功'
});
},
// 点击评论
doComment() {
console.log('Commenting...');
},
// 点击分享
doShare() {
console.log('Sharing...');
},
// 预览图片
preview(index) {
uni.previewImage({
urls: this.imagesList,
current: index
})
},
// 提交评论
submit(data) {
console.log(data);
}
}
}
script>
<style>
style>
显示：
可以看到，底部输入框组件封装成功，模拟出了添加评论。
6.评论列表组件开发
评论列表组件使用uni-app官方提供的模板，如下：
<view class="p-2 font-md font-weight-bold">
最新评论 3
view>
<view class="uni-comment-list px-2">
<view class="uni-comment-face">
<image src="https://img-cdn-qiniu.dcloud.net.cn/uniapp/images/[email protected]" mode="widthFix">image>
view>
<view class="uni-comment-body">
<view class="uni-comment-top"><text>Oliviatext>
view>
<view class="uni-comment-content">大佬，写的不错view>
<view class="uni-comment-date">
<view>2天前view>
view>
view>
view>
显示：
可以看到，实现了评论列表。
7.分享功能组件开发
分享功能也是使用uni-popup组件实现，类型是bottom从底部弹出，如下：
<uni-popup ref="popup" type="bottom">
<view class="popup-content text-center py-2 font-md border-bottom border-light-secondary">分享到view>
<view class="popup-content flex align-center">
<block v-for="(item, index) in shareList" :key="index">
<view class="flex-1 flex flex-column align-center justify-center py-2" hover-class="bg-light">
<view class="iconfont text-white font-lg rounded-circle flex align-center justify-center" :class="item.icon+' '+item.color" style="width: 100rpx; height: 100rpx;">view>
<text class="font-sm mt-1 text-muted">{
{item.name}}text>
view>
block>
view>
<view class="popup-content text-center py-2 font-md border-top border-light-secondary" hover-class="bg-light">取消view>
uni-popup>
<script>
import commonList from '@/components/common/common-list.vue';
import bottomInput from '@/components/common/bottom-input.vue';
import uniPopup from '@/components/uni-ui/uni-popup/uni-popup.vue';
export default {
data() {
return {
// 当前帖子信息
info: {
},
shareList: [
{
icon: 'icon-weixin',
color: 'bg-green',
name:'微信好友'
},
{
icon: 'icon-pengyouquan',
color: 'bg-brown',
name:'朋友圈'
},
{
icon: 'icon-weibo',
color: 'bg-red',
name:'微博'
},
{
icon: 'icon-qq',
color: 'bg-blue',
name:'QQ好友'
}
]
}
},
components: {
commonList,
bottomInput,
uniPopup
},
computed: {
imagesList() {
return this.info.images.map(item => item.url);
}
},
onLoad(e) {
console.log(e);
// 初始化操作
if (e.detail) {
this.__init(JSON.parse(e.detail));
}
},
onNavigationBarButtonTap() {
this.$refs.popup.open();
},
onBackPress() {
this.$refs.popup.close();
},
methods: {
__init(data) {
// 修改标题
uni.setNavigationBarTitle({
title: data.title
});
// 请求API
this.info = data;
},
// 关注
follow() {
this.info.isFollow = true;
uni.showToast({
title: '关注成功'
});
},
// 顶踩操作
doSupport(e) {
let msg = e.type === 'support' ? '顶' : '踩';
// 之前操作过
if (this.info.support.type === e.type) {
return uni.showToast({
title: '您已经' + msg + '过了'
});
}
// 之前未操作过
if (this.info.support.type === '') {
this.info.support[e.type + '_count']++;
}
// 之前已顶过并且现在的操作为踩，则顶-1、踩+1
else if (this.info.support.type === 'support' && e.type === 'unsupport') {
this.info.support.support_count--;
this.info.support.unsupport_count++;
}
// 之前已踩过并且现在的操作为顶，则踩-1、顶+1
else if (this.info.support.type === 'unsupport' && e.type === 'support') {
this.info.support.unsupport_count--;
this.info.support.support_count++;
}
this.info.support.type = e.type;
uni.showToast({
title: msg + '成功'
});
},
// 点击评论
doComment() {
console.log('Commenting...');
},
// 点击分享
doShare() {
console.log('Sharing...');
},
// 预览图片
preview(index) {
uni.previewImage({
urls: this.imagesList,
current: index
})
},
// 提交评论
submit(data) {
console.log(data);
}
}
}
script>
为了本文项目练手所需，需要在https://www.iconfont.cn/中下载微信、朋友圈、微博、QQ等图标，同时将icon.css和iconfont.ttf更新为最新状态。
显示：
可以看到，实现了图标。
再进一步封装为组件，在components/common目录下新建more-share组件，如下：
<template>
<uni-popup ref="popup" type="bottom">
<view class="popup-content text-center py-2 font-md border-bottom border-light-secondary">分享到view>
<view class="popup-content flex align-center">
<block v-for="(item, index) in shareList" :key="index">
<view class="flex-1 flex flex-column align-center justify-center py-2" hover-class="bg-light">
<view class="iconfont text-white font-lg rounded-circle flex align-center justify-center" :class="item.icon+' '+item.color" style="width: 100rpx; height: 100rpx;">view>
<text class="font-sm mt-1 text-muted">{
{item.name}}text>
view>

detail.vue如下：
<more-share ref="share">more-share>
onNavigationBarButtonTap() {
this.$refs.share.open();
},
onBackPress() {
this.$refs.share.close();
},
效果与之前相同。
分享接口可参考hello_uniapp参考项目下pages/API下的share页面，使用的是uni.getProvider()接口动态获取服务商，如下：
<template>
<uni-popup ref="popup" type="bottom">
<view class="popup-content text-center py-2 font-md border-bottom border-light-secondary">分享到view>
<view class="popup-content flex align-center">
<block v-for="(item, index) in providerList" :key="index">
<view class="flex-1 flex flex-column align-center justify-center py-2" hover-class="bg-light" @tap="share(item)">
<view class="iconfont text-white font-lg rounded-circle flex align-center justify-center" :class="item.icon+' '+item.color"
style="width: 100rpx; height: 100rpx;">view>
<text class="font-sm mt-1 text-muted">{
{item.name}}text>

可以看到，实现了分享到微信好友和朋友圈。
总结
在进行uni-app开发时，因为官方提供了很多模板、组件和接口，可以实现常见的功能，我们可以在其基础上进行稍微的优化和改动，即可用于自己项目，例如评论列表模板、分享组件和API，这样可以大大加快开发效率。
