SignalR通知及控制台日志示例 - 新一代.NET开发平台

在后台业务服务类中使用INotifyService发送通知

[WebApi, Service] // 构造函数注入INotifyService
class HomeService(Context context, INotifyService service) : ServiceBase(context)
{
    public Task DoXXXXAsync()
    {
        // 往母版页发送系统通知
        service.LayoutNotifyAsync("系统通知", "XXX服务已启动！");
    }
}

KConsole组件使用示例

在后端添加TestWorker后台服务

public class AppConstant
{
    public const string AddLog = "AddLog"; // 定义SignalR方法名
}

class TestWorker(INotifyService service) : BackgroundService
{
    private readonly TimeSpan _interval = TimeSpan.FromSeconds(1);

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            // 每秒往BizId为Test的控制台组件发送日志
            await service.SendAsync(AppConstant.AddLog, new ConsoleLogInfo
            {
                BizId = "Test",
                Type = ConsoleLogType.Info,
                Content = $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} 测试日志信息"
            }, stoppingToken);
            await Task.Delay(_interval, stoppingToken);
        }
    }
}

在后端AppServer中注册TestWorker

static class AppServer
{
    internal static void AddApplicationWeb(this IServiceCollection services, Action<CoreOption> action)
    {
        services.AddHostedService<TestWorker>(); // 注册TestWorker
    }
}

在前端添加组件显示实时日志

<KButton Type="@ButtonType.Primary" Name="日志" OnClick="OnLog" />
@code {
    // 弹窗显示控制台日志组件，实时显示TestWorker发送的日志
    private void OnLog()
    {
        var model = new DialogModel
        {
            Title = "控制台日志",
            Width = 600,
            Maximizable = true,
            Content = b => b.Component<KConsole>()
                            .Set(c => c.BizId, "Test")                   // BizId：日志业务ID
                            .Set(c => c.MethodName, AppConstant.AddLog)  // MethodName：SignalR方法名
                            .Build()
        };
        UI.ShowDialog(model);
    }
}
