**体育赛事直播系统的炫彩弹幕直播间界面，“东莞梦幻网络科技”的源码技术实现方案，包括前端(Vue.js)、后端(ThinkPHP)、安卓(Java)和iOS(Objective-C)的实现代码。**
## 系统架构设计
**技术栈**
后端: PHP (ThinkPHP 6.x)
数据库: MySQL + Redis
前端: Vue.js 3 + Element Plus
移动端:
Android: Java + Retrofit
iOS: Objective-C + AFNetworking
实时通信: WebSocket (Swoole)
## 后端实现 (ThinkPHP)
**数据库设计**
```objectivec
// 直播表
Schema::create('live_streams', function (Blueprint $table) {
$table->id();
$table->string('title'); // 直播标题
$table->integer('sport_type'); // 运动类型
$table->string('home_team'); // 主队
$table->string('away_team'); // 客队
$table->datetime('start_time'); // 开始时间
$table->string('stream_url'); // 直播流地址
$table->integer('viewer_count')->default(0); // 观看人数
$table->integer('status')->default(0); // 状态 0-未开始 1-直播中 2-已结束
$table->timestamps();
});
// 弹幕表
Schema::create('barrages', function (Blueprint $table) {
$table->id();
$table->integer('live_id'); // 直播ID
$table->integer('user_id'); // 用户ID
$table->string('content'); // 弹幕内容
$table->string('color')->default('#FFFFFF'); // 颜色
$table->integer('position')->default(0); // 位置
$table->timestamps();
});
```
**控制器代码**
```objectivec
namespace app\controller;
use app\BaseController;
use think\facade\Db;
use think\facade\Request;
class LiveController extends BaseController
{
// 获取直播列表
public function getLiveList()
{
$page = Request::param('page', 1);
$size = Request::param('size', 10);
$list = Db::name('live_streams')
->where('status', '>=', 0)
->order('start_time', 'desc')
->paginate(['page' => $page, 'list_rows' => $size]);
return json([
'code' => 200,
'data' => $list->items(),
'total' => $list->total()
]);
}
// 获取直播详情
public function getLiveDetail($id)
{
$live = Db::name('live_streams')->find($id);
if (!$live) {
return json(['code' => 404, 'msg' => '直播不存在']);
}
return json([
'code' => 200,
'data' => $live
]);
}
// 发送弹幕
public function sendBarrage()
{
$data = Request::only(['live_id', 'content', 'color', 'position']);
$data['user_id'] = Request::middleware('user_id');
$id = Db::name('barrages')->insertGetId($data);
// 通过WebSocket广播弹幕
$this->app->swoole->pushToAll(json_encode([
'type' => 'barrage',
'data' => array_merge($data, ['id' => $id])
]));
return json(['code' => 200, 'msg' => '发送成功']);
}
// 获取弹幕列表
public function getBarrages($live_id)
{
$list = Db::name('barrages')
->where('live_id', $live_id)
->order('create_time', 'desc')
->limit(100)
->select();
return json([
'code' => 200,
'data' => $list
]);
}
}
```
## Web前端实现 (Vue.js)
**页面结构**
```objectivec
```
**Vue组件逻辑**
```objectivec
```
**样式部分**
```objectivec
```
## 移动端实现
**Android实现 (Java)**
```objectivec
// LiveActivity.java

});

});
// 发送弹幕
sendButton.setOnClickListener(v -> {
String content = barrageEdit.getText().toString();
if (!TextUtils.isEmpty(content)) {
viewModel.sendBarrage(liveId, content);
barrageEdit.setText("");
}
});
// 加载数据

}
@Override

}
}
// LiveViewModel.java

}

}

@Override

self.barrageTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, self.view.bounds.size.width - 80, 30)];

## 实时通信方案
**WebSocket服务端实现 (Swoole)**
```objectivec
namespace app\websocket;
use think\swoole\Websocket;
class LiveWebsocket
{
protected $websocket;
// 用户连接
protected $connections = [];
public function __construct(Websocket $websocket)
{
$this->websocket = $websocket;
}
// 连接建立
public function onOpen($ws, $request)
{
$liveId = $request->get['live_id'];
$userId = $request->get['user_id'];
$this->connections[$liveId][$userId] = $ws->fd;
// 更新观看人数
$count = count($this->connections[$liveId] ?? []);
$this->websocket->emit('viewer_count', [
'live_id' => $liveId,
'count' => $count
]);
}
// 收到消息
public function onMessage($ws, $frame)
{
$data = json_decode($frame->data, true);
switch ($data['type']) {
case 'barrage':
// 广播弹幕
$this->broadcastToLive($data['data']['live_id'], [
'type' => 'barrage',
'data' => $data['data']
]);
break;
case 'heartbeat':
// 心跳检测
break;
}
}
// 连接关闭
public function onClose($ws, $fd)
{
foreach ($this->connections as $liveId => $users) {
if (($key = array_search($fd, $users)) !== false) {
unset($this->connections[$liveId][$key]);
// 更新观看人数
$count = count($this->connections[$liveId] ?? []);
$this->websocket->emit('viewer_count', [
'live_id' => $liveId,
'count' => $count
]);
break;
}
}
}
// 广播到指定直播间
protected function broadcastToLive($liveId, $data)
{
if (isset($this->connections[$liveId])) {
foreach ($this->connections[$liveId] as $fd) {
$this->websocket->push($fd, json_encode($data));
}
}
}
}
```
**这个实现方案涵盖了从后端到前端，再到移动端的完整实现，您可以根据实际需求进行调整和扩展。**
