TouchSocket.SocketIo

TouchSocket 框架的 Socket.IO 协议组件，提供完整的 Socket.IO 客户端实现。

协议支持

  • 兼容 Socket.IO 3.x 和 4.x 协议
  • 支持 Engine.IO v3 和 v4 协议

传输方式

传输方式 说明
WebSocket 高性能双向通信
HTTP 长轮询 兼容性回退方案
自动升级 默认先通过 HTTP 长轮询握手，成功后自动升级为 WebSocket

核心特性

  • Emit/Ack 模型 — EmitAsync 发送事件，EmitWithAckAsync 发送并等待 Ack 响应
  • 命名空间 — 支持连接到指定 Namespace（如 /chat）
  • 二进制附件 — 完整支持 _placeholder 占位符机制
  • 自定义 Query — 握手时可携带自定义查询参数
  • 插件扩展 — 通过 ISocketIoEventPlugin 拦截事件，ISocketIoHandshakedPlugin 监听握手
  • 可替换序列化器 — 默认内置 System.Text.Json，支持通过 ISocketIoSerializer 自定义

快速使用

var client = new SocketIoClient();
client.Setup(new TouchSocketConfig()
    .SetRemoteIPHost("http://localhost:3000")
    .Configure<SocketIoOption>(opt =>
    {
        opt.EIO = EngineIoVersion.V4;
        opt.Transport = EngineIoTransportType.WebSocket;
        opt.Namespace = "/chat";
    }));

await client.ConnectAsync();

// 发送事件
await client.EmitAsync("message", "hello");

// 发送并等待 Ack
var response = await client.EmitWithAckAsync("query", new object[] { "id" }, 5000);
var result = response.GetValue<string>(0);
