QuickStart

1. Install Library / 安装库

# Package Manager
Install-Package Cyaim.WebSocketServer

# .NET CLI
dotnet add package Cyaim.WebSocketServer

# PackageReference
<PackageReference Include="Cyaim.WebSocketServer" Version="1.7.8" />

2. Configure WebSocket Server / 配置 WebSocket 服务器

Using Minimal API / 使用 Minimal API

using Cyaim.WebSocketServer.Infrastructure.Handlers.MvcHandler;
using Cyaim.WebSocketServer.Middlewares;

var builder = WebApplication.CreateBuilder(args);

// Configure WebSocket route / 配置 WebSocket 路由
builder.Services.ConfigureWebSocketRoute(x =>
{
    var mvcHandler = new MvcChannelHandler();
    x.WebSocketChannels = new Dictionary<string, WebSocketRouteOption.WebSocketChannelHandler>()
    {
        { "/ws", mvcHandler.ConnectionEntry }
    };
    x.ApplicationServiceCollection = builder.Services;
});

var app = builder.Build();

// Configure WebSocket options / 配置 WebSocket 选项
var webSocketOptions = new WebSocketOptions()
{
    KeepAliveInterval = TimeSpan.FromSeconds(120),
};
app.UseWebSockets(webSocketOptions);
app.UseWebSocketServer();

app.Run();

Using Startup.cs / 使用 Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.ConfigureWebSocketRoute(x =>
    {
        var mvcHandler = new MvcChannelHandler();
        x.WebSocketChannels = new Dictionary<string, WebSocketRouteOption.WebSocketChannelHandler>()
        {
            { "/ws", mvcHandler.ConnectionEntry }
        };
        x.ApplicationServiceCollection = services;
    });
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    var webSocketOptions = new WebSocketOptions()
    {
        KeepAliveInterval = TimeSpan.FromSeconds(120),
    };
    app.UseWebSockets(webSocketOptions);
    app.UseWebSocketServer();
}

3. Mark WebSocket Endpoints / 标记 WebSocket 端点

Add [WebSocket] attribute to your controller actions:

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    [WebSocket]  // Mark as WebSocket endpoint / 标记为 WebSocket 端点
    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {
        var rng = new Random();
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
        {
            Date = DateTime.Now.AddDays(index),
            TemperatureC = rng.Next(-20, 55),
            Summary = Summaries[rng.Next(Summaries.Length)]
        }).ToArray();
    }
}

Note: The target parameter in requests is case-insensitive.
注意: 请求中的 target 参数不区分大小写。

Request and Response

Scheme namespace 👇
Request Cyaim.WebSocketServer.Infrastructure.Handlers.MvcRequestScheme
Response Cyaim.WebSocketServer.Infrastructure.Handlers.MvcResponseScheme

Request target ignore case

Request scheme

1. Nonparametric method request

{
	"target": "WeatherForecast.Get",
	"body": {}
}

This request will be located at "WeatherForecastController" -> "Get" Method.

Response to this request

{
	"Target": "WeatherForecast.Get"
	"Status": 0,
	"Msg": null,
	"RequestTime": 637395762382112345,
	"CompleteTime": 637395762382134526,
	"Body": [{
		"Date": "2020-10-30T13:50:38.2133285+08:00",
		"TemperatureC": 43,
		"TemperatureF": 109,
		"Summary": "Scorching"
	}, {
		"Date": "2020-10-31T13:50:38.213337+08:00",
		"TemperatureC": 1,
		"TemperatureF": 33,
		"Summary": "Chilly"
	}]
}

Forward invoke method return content will write MvcResponseScheme.Body.

2. Request with parameters

Example Code:

Change method code to:

[WebSocket]
[HttpGet]
public IEnumerable<WeatherForecast> Get(Test a)
{
    var rng = new Random();
    return Enumerable.Range(1, 2).Select(index => new WeatherForecast
    {
         TemperatureC = a.PreTemperatureC + rng.Next(-20, 55),
         Summary = a.PreSummary + Summaries[rng.Next(Summaries.Length)]
    }).ToArray();
}

Define parameter class

public class Test
{
    public string PreSummary { get; set; }
    public int PreTemperatureC { get; set; }
}

Request parameter

{
	"target": "WeatherForecast.Get",
	"body": {
	    "PreSummary":"Cyaim_",
	    "PreTemperatureC":233
	}
}

Request body will be deserialized and passed to the method parameter.

Response to this request

{
	"Target": "WeatherForecast.Get",
	"Status": 0,
	"Msg": null,
	"RequestTime": 0,
	"CompleteTime": 637395922139434966,
	"Body": [{
		"Date": "0001-01-01T00:00:00",
		"TemperatureC": 282,
		"TemperatureF": 539,
		"Summary": "Cyaim_Warm"
	}, {
		"Date": "0001-01-01T00:00:00",
		"TemperatureC": 285,
		"TemperatureF": 544,
		"Summary": "Cyaim_Sweltering"
	}]
}

Client SDKs / 客户端 SDK

We provide multi-language client SDKs with automatic endpoint discovery:

C# - Cyaim.WebSocketServer.Client
TypeScript/JavaScript - @cyaim/websocket-client
Rust - cyaim-websocket-client
Java - websocket-client
Dart - cyaim_websocket_client
Python - cyaim-websocket-client

Quick Example / 快速示例

C# Client:

using Cyaim.WebSocketServer.Client;

var factory = new WebSocketClientFactory("http://localhost:5000", "/ws");
var client = await factory.CreateClientAsync<IWeatherService>();
var forecasts = await client.GetForecastsAsync();

TypeScript Client:

import { WebSocketClientFactory } from '@cyaim/websocket-client';

const factory = new WebSocketClientFactory('http://localhost:5000', '/ws');
const client = await factory.createClient<IWeatherService>({
  getForecasts: async () => {}
});
const forecasts = await client.getForecasts();

Cluster / 集群

Cyaim.WebSocketServer supports multi-node clustering with Raft consensus protocol. You can use WebSocket, Redis, or RabbitMQ for inter-node communication.

Basic Cluster Setup / 基础集群配置

using Cyaim.WebSocketServer.Infrastructure.Cluster;
using Cyaim.WebSocketServer.Infrastructure.Configures;

var builder = WebApplication.CreateBuilder(args);

// Configure WebSocket route / 配置 WebSocket 路由
builder.Services.ConfigureWebSocketRoute(x =>
{
    var mvcHandler = new MvcChannelHandler();
    x.WebSocketChannels = new Dictionary<string, WebSocketRouteOption.WebSocketChannelHandler>()
    {
        { "/ws", mvcHandler.ConnectionEntry }
    };
    x.ApplicationServiceCollection = builder.Services;
});

var app = builder.Build();

// Configure WebSocket / 配置 WebSocket
app.UseWebSockets();
app.UseWebSocketServer(serviceProvider =>
{
    // Configure cluster / 配置集群
    var clusterOption = new ClusterOption
    {
        NodeId = "node1",
        NodeAddress = "localhost",
        NodePort = 5000,
        TransportType = "ws", // or "redis" or "rabbitmq"
        ChannelName = "/cluster",
        Nodes = new[]
        {
            "ws://localhost:5001/node2",
            "ws://localhost:5002/node3"
        }
    };
    
    return clusterOption;
});

app.Run();

Using Redis Transport / 使用 Redis 传输

# Install Redis transport package / 安装 Redis 传输包
dotnet add package Cyaim.WebSocketServer.Cluster.StackExchangeRedis

var clusterOption = new ClusterOption
{
    NodeId = "node1",
    TransportType = "redis",
    RedisConnectionString = "localhost:6379",
    ChannelName = "/cluster",
    Nodes = new[] { "node1", "node2", "node3" }
};

Using RabbitMQ Transport / 使用 RabbitMQ 传输

# Install RabbitMQ transport package / 安装 RabbitMQ 传输包
dotnet add package Cyaim.WebSocketServer.Cluster.RabbitMQ

var clusterOption = new ClusterOption
{
    NodeId = "node1",
    TransportType = "rabbitmq",
    RabbitMQConnectionString = "amqp://guest:guest@localhost:5672/",
    ChannelName = "/cluster",
    Nodes = new[] { "node1", "node2", "node3" }
};
