剃刀组件从控制器页面预订事件

Question

我正在使用Razor组件Blazor服务器端ASP.NET Core项目。我有一个控制器，当收到新消息时，我从外部服务获取HTTP Post。我希望我的剃须刀组件在消息到达时立即显示它们。我希望多个剃刀组件能够注册到该事件

是否有一种方法可以从剃须刀组件注册到控制器内部的事件？还是应该使用其他方法，例如Xamarin Message Center？

控制器：

public class LoRaServerController : ControllerBase
{
    public event EventHandler<SensorData>? OnNewSensorData;
    // POST: api/LoRaServer
    [HttpPost]
    public async void PostUplink()
    {
        if (OnNewSensorData != null)
        {
            var uplink = await DeserializeBody<Uplink>(Request.Body);
            if (uplink != null)
                OnNewSensorData(this, new SensorData(uplink));
        }
    }

    private async Task<T?> DeserializeBody<T>(Stream body) where T : class
    {
        //Json deserialization...
    }
}

剃刀组件：

@attribute [Authorize(Roles = "Administrator")]
@page "/lora-debug"
@using Xxx.Controller
@using Xxx.Services.Entities
@inject LoRaServerController _ctrl; //this doesn't work as controllers are no services...
@implements IDisposable;
<h3>Sensor Server Debug</h3>


<table class="table">
    <thead>
        <tr>
            <th>Time</th>
            <th>EUI</th>
            <th>Uptime</th>
            <th>Voltage</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var msg in sensorData)
        {
            <tr>
                <td>@msg.Timestamp</td>
                <td>@msg.DeviceEUI</td>
                <td>@msg.Uptime</td>
                <td>@msg.Voltage</td>
            </tr>
        }
    </tbody>
</table>

@code {

    private List<SensorData> sensorData = new List<SensorData>();

    protected override void OnInitialized()
    {
        _ctrl.OnNewSensorData += Instance_OnNewSensorData;
    }

    public void Dispose()
    {
        _ctrl.OnNewSensorData -= Instance_OnNewSensorData;
    }


    private void Instance_OnNewSensorData(object? sender, SensorData e)
    {
        sensorData.Add(e);
        InvokeAsync(() => this.StateHasChanged());
    }
}
