如何在C#中将数据从SignalR集线器推送到客户端

using Microsoft.AspNetCore.SignalR;

public class MyHub : Hub
{
    public async Task SendMessage(string message)
    {
        // 将消息发送给所有连接的客户端
        await Clients.All.SendAsync("ReceiveMessage", message);
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddSignalR();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // ...

    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapHub<MyHub>("/myhub"); // 配置SignalR的端点
    });
}

var connection = new HubConnectionBuilder()
    .WithUrl("https://example.com/myhub") // 指定SignalR集线器的URL
    .Build();

connection.On<string>("ReceiveMessage", message =>
{
    // 处理从集线器接收到的消息
    Console.WriteLine(message);
});

await connection.StartAsync(); // 连接到SignalR集线器

public async Task SendMessage(string message)
{
    await Clients.All.SendAsync("ReceiveMessage", message);
}
