本篇内容主要讲解“Laravel8/LaravelS如何实现弹幕功能”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Laravel8/LaravelS如何实现弹幕功能”吧!
第一步：安装Laravel8
composer create-project laravel/laravel labarrage 第二步：Laravel8中使用vue
注意：安装vue时请使用 php artisan ui vue --auth
第三步：安装及安装vue-baberrage
安装vue及bootstrap
npm install 安装弹幕组件
npm install vue-baberrage --save 运行
npm run dev第四步：安装LaravelS实现Websocket服务器
请参考 Laravel8使用laravel-s实现WebSocket服务器
第五步：项目中引入vue-baberrage组件
文件：resources/js/app.js 新增如下内容
import { vueBaberrage } from 'vue-baberrage'
Vue.use(vueBaberrage)
Vue.component('danmu-component', require('./components/DanmuComponent.vue').default);第五步：编写文弹幕组件
位置：resources/js/components/DanmuComponent.vue
<template> <div id="danmu"> <div class="stage"> <vue-baberrage
:isShow = "barrageIsShow"
:barrageList = "barrageList"
:loop = "barrageLoop"
:maxWordCount = "60"
> </vue-baberrage> </div> <div class="danmu-control"> <div> <select v-model="position"> <option value="top">从上</option> <option value="abc">从右</option> </select> <input type="text" style="float:left" v-model="msg"/> <button type="button" style="float:left" @click="addToList">发送</button> </div> </div> </div> </template> <script> import { MESSAGE_TYPE } from 'vue-baberrage'
export default {
name: 'danmu',
data () {
return {
msg: 'hello 自如初！',
position: 'top',
barrageIsShow: true,
currentId: 0,
barrageLoop: false,
barrageList: []
}
},
methods: {
removeList () {
this.barrageList = []
},
addToList () {
if (this.position === 'top') {
this.barrageList.push({
id: ++this.currentId,
msg: this.msg + this.currentId,
barrageStyle: 'top',
time: 8,
type: MESSAGE_TYPE.FROM_TOP,
position: 'top'
})
} else {
this.barrageList.push({
id: ++this.currentId,
msg: this.msg,
time: 15,
type: MESSAGE_TYPE.NORMAL
})
}
}
}
} </script> <style lang="scss" scoped> #danmu {
text-align: center;
color: #2c3e50;
}
.stage {
height: 300px;
width: 100%;
background: #025d63;
margin: 0;
position: relative;
overflow: hidden;
}
h2, h3 {
font-weight: normal;
}
ul {
list-style-type: none;
padding: 0;
}
li {
display: inline-block;
margin: 0 10px;
}
a {
color: #42b983;
}
.baberrage-stage {
z-index: 5;
}
.baberrage-stage .baberrage-item.normal{
color:#FFF;
}
.top{
border:1px solid #66aabb;
}
.danmu-control{
position: absolute;
margin: 0 auto;
width: 100%;
bottom: 300px;
top: 70%;
height: 69px;
box-sizing: border-box;
text-align: center;
display: flex;
justify-content: center;
div {
width: 300px;
background: rgba(0, 0, 0, 0.6);
padding: 15px;
border-radius: 5px;
border: 2px solid #8ad9ff;
}
input,button,select{
height:35px;
padding:0;
float:left;
background:#027fbb;
border:1px solid #CCC;
color:#FFF;
border-radius:0;
width:18%;
box-sizing: border-box;
}
select{
height:33px;
margin-top:1px;
border: 0px;
outline: 1px solid rgb(204,204,204);
}
input{
width:64%;
height:35px;
background:rgba(0,0,0,.7);
border:1px solid #8ad9ff;
padding-left:5px;
color:#FFF;
}
} </style>第六步：视图中使用组件
位置：resources/views/danmu.blade.php
@extends('layouts.app')
@section('content')
<danmu-component></danmu-component>
@endsection第七步：注册路由
Route::get('/danmu', function() {
return view('danmu');
});执行 npm run dev
第八步：编写websocket服务器
文件：AppHandlersWebSocketHandler.php
<?php
namespace AppHandlers;
use Hhxsv5LaravelSSwooleWebSocketHandlerInterface;
use IlluminateSupportFacadesLog;
use SwooleHttpRequest;
use SwooleWebSocketFrame;
use SwooleWebSocketServer;
class WebSocketHandler implements WebSocketHandlerInterface
{
public function __construct()
{
}
// 连接建立时触发
public function onOpen(Server $server, Request $request)
{
Log::info('WebSocket 连接建立:' . $request->fd);
}
// 收到消息时触发
public function onMessage(Server $server, Frame $frame)
{
// $frame->fd 是客户端 id，$frame->data 是客户端发送的数据
Log::info("从 {$frame->fd} 接收到的数据: {$frame->data}");
foreach($server->connections as $fd){
if (!$server->isEstablished($fd)) {
// 如果连接不可用则忽略
continue;
}
$server->push($fd , $frame->data); // 服务端通过 push 方法向所有连接的客户端发送数据
}
}
// 连接关闭时触发
public function onClose(Server $server, $fd, $reactorId)
{
Log::info('WebSocket 连接关闭:' . $fd);
}
}第九步：laravels.php注册
文件：config/laravels.php
'websocket' => [
'enable' => true,
'handler' => AppHandlersWebSocketHandler::class,
],第十步：启动
php bin/laravels start
