uniapp 聊天界面-仿微信聊天界面设计

简介：
本篇文章带来的是仿照微信设计的聊天界面，主要涉及到三个文件；下方已有介绍，代码块中也有相关说明，直接复制然后就可使用；注意获取消息的websoket和拉取历史消息的接口还是需要自己去写，下方只做大致参考；具体消息格式下方代码块中已列出

一、聊天主界面chatIndex.vue

二、timeMethod.js 工具类，在聊天界面会被引入

class TimeMethod {
	
	constructor() {}
	
	//日期格式化
	addZero(data) {
		if (parseInt(data) < 10) {
			return "0" + String(data);
		}
		return data;
	}	
	
	/**
	 * 获取当前日期
	 */
	getNowTime() {
		var myDate = new Date();
		let year = myDate.getFullYear();
		let mouth = this.addZero(myDate.getMonth());
		let day = this.addZero(myDate.getDate());
		let hour = this.addZero(myDate.getHours());
		let minute = this.addZero(myDate.getMinutes());
		let second = this.addZero(myDate.getSeconds());
		return year + '-' + String((parseInt(mouth)+1)) + '-' + day + 'T' + hour+ ':' + minute+ ':' + second
	}
	
	/**
	 * @param {Object} timestamp
	 * @param {Object} type
	 * 时间戳转时间
	 */
	timestampToTime(timestamp,type) {
			if(String(timestamp).length===10) {
				//时间戳为10位需*1000
				var date = new Date(timestamp * 1000);
			}else {
				var date = new Date(timestamp);
			}
	        var Y = date.getFullYear() + '-';	
	        var M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';	
	        var D = date.getDate() + ' ';	
	        var h = date.getHours() + ':';	
	        var m = date.getMinutes() + ':';	
	        var s = date.getSeconds();
			if(type==="date") {
				return Y+M+D;
			}else {
				return Y+M+D+h+m+s;
			}
	    }
		
		
	/**
	 * @param {Object} time
	 * 时间转时间戳
	 */
	timeToTimestamp(time) {
		//精确到秒，毫秒用000代替 ：Date.parse(date); 
		return new Date(time).getTime(); 
	}
	
	
	/**

		return weekArrayList[new Date(time).getDay()]
	}
	
	/**
	 * @param {Object} date
	 *  yyyy-MM-dd HH:mm:ss转为   yyyy-MM-ddTHH:mm:ss
	 */
	timeFormat(date,type) {
		if (type == "T")
			return date.replace(" ","T")
		else
			return date.replace("T"," ")
	}
	
	/**
	 * @param {Object} time
	 * 定时器
	 */
	timeSleep(time) {

	}

}

export default new TimeMethod();

三、消息菜单组件 ChatMsgMenu.vue（会在消息功能菜单中引用，长按消息会显示该菜单），组件使用的uniapp easycome模式，直接拿来使用即可

<template>
	<view class="menu-box">
		<view  v-for="item,index in menuList" :key="item.id">
			<view class="menu-box-inner" v-if="msgUserId==userId || !item.isShowSelf" @click="clickMenu(item.type,content)">
				<image class="menu-icon" :src="item.icon" />
				<view class="text-style">{{ item.name }}view>									
			view>
		view>
	view>
template>

<script>
export default {
	props: {
		msgUserId: {
			type: String,
			default: ""
		},
		msgId: {
			type: Number,
			default: 0
		},
		msgSortId: {
			type: Number,
			default: 0
		},
		content: {
			type: String,
			default: ""
		}
		,time: {
			type: String,
			default: ""
		}
	},
	data() {
		return {
			menuList: [
				{"id":1,"isShowSelf":true,"name":"撤回","type":"cancel","icon":"http://xxx/static/app/logo/publicLogo/cancel.png"},
				{"id":2,"isShowSelf":false,"name":"复制","type":"copy","icon":"http://xxx/static/app/logo/publicLogo/copy.png"},
				{"id":3,"isShowSelf":false,"name":"引用","type":"quote","icon":"http://xxx/static/app/logo/publicLogo/quote.png"}
			],
			userId: uni.getStorageSync("userId")
		}
	},
	methods: {
		
		//点击菜单
		clickMenu(type,text) {
			switch(type) {
				case "cancel":
					this.delMsg();
					break;
				case "copy":
					this.copyText(text)
					break;
				default:
					console.log(type)
			}
		},
		
		//撤回消息
		delMsg() {
			this.$request("/msg/delMsg","DELETE",{"msgId":this.msgId},{"Content-Type":"application/x-www-form-urlencoded"}).then(res=>{
				if (res.data.status=="ok") {
					uni.showToast({
						icon: "none",
						title: "消息已撤回",
						duration: 1000
					})	
					this.$emit("cancelMsg",this.msgSortId);
				}
			})
		},
		
		//复制信息
		copyText(text) {
			wx.setClipboardData({
				data: text,
				success(res) {
					 wx.getClipboardData({
						 success(res) {
							 uni.showToast({
							 	icon: 'none',
								title: "复制成功",
								duration: 1000

						 }
					 })
				}
			})
		}
	}
