```APIDOC
## WebSocket Client Connection Example

### Description
Demonstrates how to connect to the local WebSocket server (`ws://127.0.0.1:8888`) using JavaScript to receive and process real-time danmaku and other live stream events.

### Usage Example (JavaScript)
```javascript
const ws = new WebSocket('ws://127.0.0.1:8888');

ws.onopen = function() {
    console.log('Connected to the danmaku server');
};

ws.onmessage = function(event) {
    const message = JSON.parse(event.data);

    switch(message.Type) {
        case 1: // Member entry
            console.log(`[Enter] ${message.Data.User.NickName} joined`);
            break;
        case 2: // Follow
            console.log(`[Follow] ${message.Data.User.NickName} followed the streamer`);
            break;
        case 3: // Danmaku
            console.log(`[Danmaku] ${message.Data.User.NickName}: ${message.Data.Content}`);
            break;
        case 4: // Like
            console.log(`[Like] ${message.Data.User.NickName} liked ${message.Data.Count} times`);
            break;
        case 5: // Gift
            console.log(`[Gift] ${message.Data.User.NickName} sent ${message.Data.GiftName} x ${message.Data.RepeatCount}`);
            break;
        case 7: // Stats
            console.log(`[Stats] Online: ${message.Data.OnlineUserCountStr}, Total: ${message.Data.TotalUserCountStr}`);
            break;
        case 8: // Live status
            console.log(`[System] ${message.Data.Content}`);
            break;
    }
};

ws.onerror = function(error) {
    console.error('WebSocket error:', error);

### IBarrageGrabService Interface

Source: https://context7.com/wushuaihua520/barragegrab/llms.txt

The core interface for implementing barrage grabbing services for different live streaming platforms. It provides methods to start, stop, and restart the grabbing process, along with events for connection status.

```APIDOC
## IBarrageGrabService Interface

### Description
Defines the contract for barrage grabbing services. Allows starting, stopping, and restarting the service, and provides event notifications for connection status changes (Open, Message, Error, Close).

### Methods
- **Start(string liveId)**: Starts the barrage grabbing service for a given live stream ID.
- **Stop()**: Stops the barrage grabbing service.
- **ReStart()**: Restarts the barrage grabbing service.

### Events
- **OnOpen**: Triggered when the WebSocket connection is opened.
- **OnMessage**: Triggered when a message is received.
- **OnError**: Triggered when an error occurs.
- **OnClose**: Triggered when the connection is closed.

### Usage Example (C#)
```csharp
var douyinService = new DouyinBarrageGrabService();

douyinService.OnOpen += (sender, e) => {
    Console.WriteLine("WebSocket connection established");
};

douyinService.OnError += (sender, e) => {
    Console.WriteLine("An error occurred, attempting to reconnect...");
    douyinService.ReStart();
};

// Start grabbing (provide the live stream ID)
douyinService.Start("751990192217");

// Stop grabbing
douyinService.Stop();
```
```

--------------------------------

### Global Configuration Settings

Source: https://context7.com/wushuaihua520/barragegrab/llms.txt

Defines essential global configuration parameters for the application, including WebSocket server addresses and API endpoints.

```csharp
public static class GlobalConfigs
{
    // 本地WebSocket服务器地址（客户端连接此地址接收弹幕）
    public static string LocalWebSocketServer_Location = "ws://0.0.0.0:8888";

    // 抖音直播间URL前缀
    public static string LiveUrl_Douyin = "https://live.douyin.com";

    // 当前版本号
    public static string Version = "v1.9.1";

    // 签名API服务地址（用于获取WSS签名）
    public static string SignApi_Domain = "https://api.aiobs.cn";
    public static string SignApi_Url = "/Douyin/Douyin/SignWss";

    // API Key（测试用，生产环境需申请独立Key）
    public static string SignApi_Key = "test-apikey-xxx";
}
```

--------------------------------

### 管理 LocalWebSocketServer 本地服务器

Source: https://context7.com/wushuaihua520/barragegrab/llms.txt

展示了如何初始化本地 WebSocket 服务器、广播 JSON 消息以及释放资源。

```csharp
// 服务器初始化和启动
var wsServer = new LocalWebSocketServer();
wsServer.Start();

// 广播消息给所有已连接的客户端
await wsServer.Broadcast("{\"Type\":3,\"Data\":{\"Content\":\"Hello World\"}}");

// 重启服务器
wsServer.ReStart();

// 释放资源
wsServer.Dispose();
```

### 实现 IBarrageGrabService 接口与使用

Source: https://context7.com/wushuaihua520/barragegrab/llms.txt

定义了弹幕抓取服务的核心接口，并展示了如何实例化服务、注册事件处理程序以及控制抓取生命周期。

```csharp
// 接口定义
public interface IBarrageGrabService
{
    // 启动弹幕抓取服务
    // liveId: 直播间ID，如抖音直播间URL https://live.douyin.com/751990192217 中的 751990192217
    void Start(string liveId);

    // 停止弹幕抓取服务
    void Stop();

    // 重启弹幕抓取服务
    void ReStart();

    // WebSocket连接打开时触发
    event EventHandler? OnOpen;

    // 收到消息时触发
    event EventHandler? OnMessage;

    // 发生错误时触发
    event EventHandler? OnError;

    // 连接关闭时触发
    event EventHandler? OnClose;
}

// 使用示例
var douyinService = new DouyinBarrageGrabService();

// 注册事件处理
douyinService.OnOpen += (sender, e) => {
    Console.WriteLine("WebSocket连接已建立");
};

douyinService.OnError += (sender, e) => {
    Console.WriteLine("发生错误，尝试重连...");
    douyinService.ReStart();
};

// 启动抓取（传入直播间ID）
douyinService.Start("751990192217");

// 停止抓取
douyinService.Stop();
```

import json

def on_message(ws, message):
    data = json.loads(message)
    msg_type = data.get('Type')

    if msg_type == 1:  # 进入房间
        user = data['Data']['User']
        print(f"[进入] {user['NickName']} 来了")
    elif msg_type == 3:  # 弹幕
        user = data['Data']['User']
        content = data['Data']['Content']
        print(f"[弹幕] {user['NickName']}: {content}")
    elif msg_type == 5:  # 礼物
        user = data['Data']['User']
        gift = data['Data']['GiftName']
        count = data['Data']['RepeatCount']
        print(f"[礼物] {user['NickName']} 送出 {gift} x {count}")

def on_error(ws, error):
    print(f"错误: {error}")

def on_close(ws, close_status_code, close_msg):
    print("连接关闭")

def on_open(ws):
    print("已连接到弹幕服务器")

if __name__ == "__main__":
    ws = websocket.WebSocketApp(
        "ws://127.0.0.1:8888",
        on_open=on_open,
        on_message=on_message,

}

// 创建弹幕消息示例
var chatMessage = new OpenBarrageMessage
{
    Type = MessageTypeEnum.Chat,
    Data = new DouyinMsgChat
    {
        MsgId = 7338697347818230818,
        Content = "主播好厉害！",
